CHAPTER 1
HSE POLICY, OBJECTIVES OF THE PTW SYSTEM AND CUSTODIANSHIP
1.1 GASCO HSE POLICY
The GASCO HSE Policy includes the statement that ‘GASCO shall conduct activities
in a manner designed to minimise HSE risk to a level which is As Low As Reasonably
Practicable (ALARP)’.
Amongst its activities, GASCO requires to carry out work, which may be in
Operational or Non-Operational Areas of Plant facilities or Pipelines. In order to
manage the potential risks associated with this activity to ALARP, GASCO has
developed a Management System of Control, called the “GASCO Permit to Work
(PTW) System”. The GASCO Permit to Work System is described in this Manual.
1.2 LEGAL REQUIREMENTS
The United Arab Emirates Law No. 8, for year 1980, on Conservation of Petroleum
Resources Chapter V, Articles 91 & 92, and Ministerial Order No. 32 for year 1982,
Protection of Employees Against Occupational Hazards Article-1, state that:
“Every employer shall provide adequate preventative equipment to protect workers
against the dangers of employment accidents and occupational diseases that may
occur during the work and also against fire hazards that may result from the use of
machines and other equipment. He shall also adopt all other preventative methods
ordered by the Ministry of Labour and Social Affairs.”
“Every worker shall use the protective equipment and the clothing supplied to him for
this purpose, shall comply with all the instructions given by the employer to protect
him against hazards and shall not take any action liable to hamper compliance with
such instructions.”
“Every employer shall display detailed instructions in a conspicuous position at the
work place indicating the measures to be taken to prevent fire and protect the workers
against the hazards to which they may be exposed while performing their work.”
The GASCO PTW system is a key part of the measures implemented by GASCO to
comply with these legal requirements.
Permit to Work Standard
Rev 2.0 2009
CHAPTER 1
Page 2 of 7
1.3 OBJECTIVE OF THE PERMIT TO WORK SYSTEM
The prime objective of the GASCO PTW system is to ensure that potentially
hazardous work is properly controlled and co-ordinated. It is the means of providing
written instructions and authorisation to people carrying out such work.
It is a key part of the measures taken to safeguard people doing the work, others who
may be affected by the work, and the facilities themselves.
It uses documents to define the work, the associated hazards and the precautions to
be taken for those hazards, and includes a system of authorised signatories for the
preparation of the documents.
It defines the roles and responsibilities of persons in the GASCO Organisation, and
those of Contractor management, with respect to the GASCO PTW System.
Permit to Work Standard
Rev 2.0 2009
CHAPTER 1
Page 3 of 7
1.4 PURPOSE AND SCOPE
The purpose of the GASCO PTW System is to ensure that a safe working
environment is achieved by providing management control over the various work
activities, which may be potentially hazardous.
The PTW System provides a formal and controlled process that identifies and
communicates hazards and risks associated with planned work and ensures that
appropriate precautions and control measures are implemented so that the work can
proceed and be completed safely.
It is important to note that a Permit to Work is not a permission to carry out hazardous
work. It is an essential part of a procedure that provides instructions on how to carry
out any potentially hazardous work safely and in a managed, controlled way. The
PTW System has the following key features:
•
It allows personnel to be aware of the potentially hazardous activities being
undertaken under PTW by providing a systematic overview. The specific
arrangement for the display of Permits allows identification of potentially
conflicting work tasks, both on a geographical and time basis;
•
It defines the controls required to prevent threats from releasing hazards during
the work as well, as the recovery controls that will mitigate the effects should a
hazard be released;
•
It sets limits to the duration and extent of the work;
•
It encourages formal and careful attention to safe systems of working by requiring
the signature of specified individuals, who must confirm satisfactory completion of
the various stages of the Permit lifecycle, viz:
o
Hazard Assessment and Risk Assessment
o
Precautions and Controls
o
Worksite Preparations
o
Handover and Handback

1.5 CUSTODIANSHIP OF THE PTW SYSTEM
The GASCO PTW System requires that appropriate ‘Custodians’ within the GASCO
Organisation undertake responsibility for the PTW System.
The Principle Custodian, responsible for authorising all changes to the GASCO PTW
System, is the Senior Vice-President Operations, (SVP (O)).
The Custodian responsible for the development of the PTW System and the
co-ordination across GASCO is the GASCO HSE Vice-President (HSE).
Custodians responsible for the implementation of the PTW System are the Plant and
Pipeline Vice-Presidents (the Asset Owners).

CHAPTER 1
Page 5 of 7
1.6 DEVIATIONS FROM THE PTW SYSTEM
Deviation from the PTW System may be necessary in special circumstances, but the
safety of personnel, the protection of the environment and assets must not be
jeopardised. Once the situation is normalised, the PTW System must be re-applied.
If anybody involved in the PTW System is unsure of a course of action, he must
consult a higher authority and not take risks.
Any planned deviations from the procedures contained in this document must be
requested by the Plant or Pipeline Vice-President, in writing, to the Senior
Vice-President Operations (SVP (O)).
Approved derogations will be issued as a Supplementary PTW procedure, authorised
by SVP (O) and approved for issue by the Plant or Pipeline Division Manager for
subsequent inclusion in Chapter 10 of the PTW System Manual.
The PTW Supplementary procedure will normally only apply to the location that has
requested derogation from the procedure. The Supplementary PTW procedure will
inculde a description of the deviation and the expiry and is to be issued, by the Plant
or Pipeline Division Manager, to all registered holders of the PTW System Manual at
that location.
During the validity period of the authorised derogation, the PTW Suppliementary
procedure is to be filed in the Deviation Chapter of the PTW System Manual by each
respective manual holder.
The required validity period of any PTW Supplementary procedure is to be agreed
with SVP (O). Upon reaching the expiry date, unless further approval is obtained in
writing from the SVP (O) for an extension to the original expiry date, the PTW
Supplementary procedure is to be rescinded and copies removed by the registered
holder of each controlled copy of the PTW System Procedures Manual at that
location.

1.7 CONTROL OF PTW SYSTEM MANUAL
Only controlled copies of the PTW System Manual are to be used.
The latest revision of the PTW System Manual will be available on the GASCO
Intranet for all staff.
To ensure that the PTW Manuals in circulation are current the following document
management procedure is to be complied with:
•
Hard copies of the PTW Manual will be circulated to registered holders only. Each
copy of the PTW Manual will have a unique number and will be registered as a
controlled copy.
No uncontrolled copies of Manuals, or sections of Manuals, should be made;
The PTW Manual is designed in Sections to allow easy revision and update
without the need for reissue of the complete manual. Each section will have a
revision number and effective issue date;
Only the register holders of the PTW Procedures Manual will be issued with
updates; A transmittal note will accompany original manuals, and subsequent
revisions to manuals, to each holder of the controlled copy of the manual
The holder of the controlled copy of the manual has the responsibility for:
•
Inserting revisions,
•
Removing and destroying superseded pages,
•
Updating the history page at the front of the controlled manual;
•
Completing the amendment record;
•
Completing the return section of the transmittal note to HSE/S;
•
Advising all his staff who are ‘users’ of the PTW System with regard to the
changes.

CHAPTER 3
FRAMEWORK OF THE PTW SYSTEM
3.1 INTRODUCTION
For the purposes of this Permit to Work System, work can be described as an activity
that comprise one or more tasks. It is implicit that the work has been agreed as
necessary, having been through the planning stage of the work management process.
The Permit to Work System is concerned with authorising and managing this work.
The issue of a Permit does not, by itself, make a job safe. Those preparing for the work
can only achieve that, together with those supervising and executing the work. In
addition to the PTW System other precautions may need to be taken, e.g. in relation to
Plant Operations and Worksite Preparation phases. All levels in the organisation must
clearly understand both the PTW System and their roles within it.
3.2 Restricted and Unrestricted Areas
GASCO facilities handle both flammable and hazardous materials. To differentiate
those areas where these specific hazards exist; the GASCO PTW System requires
that each Plant and Pipeline Division classify specific areas as either a Restricted Area
or an Unrestricted Area. Additionally, there is a requirement to further define zones
within the Restricted Areas where there is an identified Hydrogen Sulphide (H2S)
hazard.
Each Plant or Pipeline Vice-President is responsible for producing a plot plan of the
site or pipeline, indicating the Restricted and Unrestricted Areas and highlighting any
H2S hazard zones.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 3 of 42
3.2.1 Restricted Areas
These are areas, defined by the Plant or Pipeline Vice-President, under control of
the duty operations shift or pipeline operations staff, which has restrictions on the
access of personnel, and which requires the application of the GASCO PTW
System for defined work activities. Examples are:
(i).
(ii).
(iii).
Operating areas of the Plant and thus require precautions and controls.
These may, or may not, include access roads;
Areas deemed to be hazardous under Hazardous Area Electrical
Classification and, therefore, requiring further controls;
Critical for the operation of the facility, e.g. Control Rooms and Electrical
substations
3.2.1.1 H2S Zones
H2S Zone
An area of the operational plant or pipeline, within a restricted area,
where there is, or there is potential for, high levels of H2S (>500ppm
mole) to be present in the process stream. Whenever work involves
breaking into the operating envelope in an H2S zone, then the area
measuring 10 to 15 metres, horizontal and vertical, shall be termed the
‘H2S Sterile Area’ and persons entering this H2S sterile area shall wear
a BA set and a personal monitor.
3.2.2 Unrestricted Areas
These are all other areas within the Plant or Pipeline perimeter fence, which have
not been defined as Restricted, and which do not normally require formal control
under the PTW System.
Unrestricted (Operational) Area
An area of the plant or pipeline, under control of the duty operations shift or
pipeline personnel, which does not normally require the application of the GASCO
PTW System, other than for specific, identified higher risk activities The appointed
Operations Asset Operator, where required, issues the Permit.
Unrestricted (Non-Operational) Area An area of the plant or pipeline, not under
the control of the duty operations shift or pipeline staff, which does not normally
require the application of the GASCO PTW System, other than for specific,
identified higher risk activities. The appointed Asset Operator, normally
Maintenance/ Engineering, where required, issues the Permit

3.3 CONTROL OF WORK WITHIN CLASSIFIED AREAS
3.3.1
Work in Restricted Areas not normally requiring a Permit
All work in a Restricted area is normally subject to full PTW System controls.
It is not, however, intended that the full PTW procedures be applied to all
activities.
It is, therefore, sensible and practicable that work activities, for which the
Activity
Risk Assessment process has shown to be of Low Risk, be permitted with a
minimum of controls. Examples of work in Restricted areas not normally
requiring a Permit are:
•
Normal routine activities, conducted by competent personnel, in
accordance with agreed operating procedures;
•
•
Visual inspection of areas and equipment, except for confined spaces;
•
•
Handling of non-hazardous materials;
•
Routine sampling of hydrocarbon products (excluding product streams
containing high levels of H2S) as per approved procedures by competent
laboratory staff.
Operation of equipment for approved operational training activities;
Routine housekeeping activities inside restricted operating areas, but
excepting electrical substations, where electrical engineering
authorisation is required for entry;
It is also permissible for Plant or Pipeline Vice-Presidents, to add to the list, for
their specific location, if a risk assessment of the work shows that a Permit
would not add value. The Plant or Pipeline Vice-President, must maintain a
register of ‘Work in Restricted Areas not normally requiring a Permit’.
A Permit is not needed when urgent action is required to prevent/minimise/limit
loss or damage of personnel or equipment, i.e. actions in emergency
situations;

CHAPTER 3
Page 5 of 42
3.3.1.1 Control of Work (not requiring a Permit) in Restricted Areas
In order that Operations staff may be aware of people visiting Restricted
Areas, or working in Restricted Areas without a Permit, a control
mechanism is required. Each site is to implement a ‘Restricted Area
Access and Work Register’. Suggested outline content for the register is:
•
•
•
•
•
Date / Time visit or work commenced;
•
Time visit or work completed.
Plant Area;
Purpose of visit / Work being undertaken;
Department / Name and signature of person(s) involved;
Approval signature of Operations Shift Controller, or Assistant Shift
Controller;
It is further recommended that the agreed list of work (as per 3.3.1),
which can be undertaken without a Permit, be appended to the
Restricted Area Access and Work Register, for reference purposes.
3.3.1.2 Control of Work in the Vicinity of Pipelines
In Pipeline Division, 30 metres either side of a designated pipeline, or
pipeline corridor, is defined as a Restricted Area. The intent is that no
work may take place within 30 metres of any Pipeline containing
hazardous material without GASCO PTW controls being applied.
In Pipeline Division, a specific form, the Authorisation to Work (ATW), is
provided (see Chapter 5, Section 5.9). The Purpose of an ATW is to
provide a process for the control of work being undertaken in the vicinity,
but not directly on, GASCO pipelines by GASCO, Third Parties or
Contractors, and to communicate this to other interested parties. A
flowchart is provided in Appendix G to aid the Permit Originator and
Permit Issuing Authorities in determining Pipeline Division PTW
requirements.
3.3.2 Control of Work (requiring a Permit) in Unrestricted Areas
In general, work in Unrestricted Areas is not required to be subject to the PTW
System. There will, however, be some work activities in Unrestricted Areas, which
are considered to be of a higher risk, which require further controls to be applied.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 6 of 42
Work in Unrestricted Areas requiring a Permit is
•
Work involving naked flame, grinding or welding (other than in defined,
approved areas e.g. Maintenance Workshops);
•
•
•
•
•
Confined Space Entry, e.g. sewers, pits or tanks;
Activities which introduce an electrical hazard;
Excavations, which are in proximity to underground services or pipelines.
Work involving a radiographic source
Any work where a hazard requiring controls is identified by the Originator,
e.g. working at heights on buildings or structures, and this list is not
exhaustive.
Depending on circumstances, Plant or Pipeline Vice-Presidents, may require
certain other work in Unrestricted areas to be subject to the PTW System. In
this case a Register of such work must be maintained. As with the 'Work in
Restricted Areas not normally requiring a Permit' (see 3.3.1) details are to be
maintained by the Plant or Pipeline Vice-President.
In Pipeline Division, where the distance from the pipeline exceeds 30 metres,
but is less than 200 metres, Third Parties and Contractors are required to
advise GASCO of proposed work activities and to obtain a No Objection
Certificate (NOC) prior to commencing work. After evaluating the risk, the Asset
Owner decides what PTW System controls (if any) are required.
3.3.2.1
Authorisation of Work in Unrestricted Areas
Where work in Unrestricted Areas is subject to the PTW System, the
authority for authorisation of work will normally be the Asset Holder of
that particular section of the site or facility.
Where there is potential to affect Plant Operations, the Operations
Shift Controller (the Asset Operator for Restricted Areas) should also
countersign the Permit.
The Plant/ Pipeline Vice-President, is responsible for authorisation of
the Asset Holders and Asset Operators, who will sign permity, for
defined areas of the site or facility.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 7 of 42
3.3.3 Work Requiring a Permit
All work to be done in a Restricted Area or H2S Zone, that is not included in
3.3.1, or is in an Unrestricted Area requiring controls, then the work is subject to
the PTW System.
3.3.4 Permits Covering more than one Work Activity
At the discretion of the Asset Holder, a Permit may be issued to cover more than
one simultaneous work activity within a designated area, subject to the following
criteria:
(i).
A Risk Assessment has shown the site conditions and hazards are of a
similar nature and can be covered on one Permit;
(ii).
There are clear isolation/ master isolation boundaries;
(iii). The same GASCO Maintenance/ Engineering discipline or Contractor is
involved, or, where considered appropriate, a lead Trade discipline has
been appointed with agreed responsibilities for overseeing the work
activities;
(iv). The jobs/ activities are all under the supervision of a single designated
PICWS (as per (iii) above) and there is no conflict with the PICWS role as
the ACCEPTOR of the Permit.
(v).
The area covered by the Permits is clearly defined on marked up drawings
(and attached to the Permit) and can be adequately supervised by one
person;
(vi). In general, the PICWS should have clear line of sight to all activities
undertaken under a single Permit, and have adequate access to, and
communication with all persons involved in the activities.
(vii). Gas tests, where required by the Permit, must be carried out as
appropriate to cover all activities within the designated area. The results
are to be recorded on the Gas Test Certificate (see Chapter 5, Section 5.2).
If any measurement is outside permissible levels, then the Permit must be
suspended and, if necessary, separate Permits issued.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 8 of 42
Typically, no more than four simultaneous activities, which meet the
aforementioned criteria, should be included on a Permit that is under the
supervision of a single PICWS. In special circumstances, the Asset Owner may
give dispensation to deviate from this standard, e.g. during major Plant
shutdowns, where the Plant is positively isolated and declared free of
hazardous and flammable materials, and it is deemed reasonable to expand
the work under the control of a single PICWS.
3.3.5
Work which requires Interface Procedures
Interface procedures apply whenever there is a risk of interference or mutual
risk between two parties working within close vicinity of each other. They exist
to ensure that all parties are aware of each others activities and that the risks
and potential hazardous interactions have been jointly identified and
communicated, and that satisfactory control measure have also been jointly
identified and implemented to allow the work activity to continue safely.
PTW Interface procedures (see 3.3.5.1 to 3.3.5.5) apply for all work being
undertaken within the following designated interface areas:
(i). Within 30m of the boundary between two different GASCO Area
Authorities who are responsible for a section of the plant within the
responsibility of the same Asset Operator;
(ii). Within 30m of the boundary between two different GASCO Asset
Operators, e.g. Habshan Plant/ Facility having different Shift Controllers;
(iii). Within 30m of an ADNOC Group Company administered area, facility or pipeline;
(iv). Where the work is conducted within the designated boundary of an
ADNOC Group Company facility, pipeline corridor or administered area by
GASCO or GASCO contractors;
(v). Where the work is conducted within the designated boundary of an
GASCO administered area, facility or pipeline corridor by an ADNOC
group company or their contractors;
(vi). Where the work is conducted within the designated boundary of a shared PTW
Interface Area by GASCO, or by GASCO contractors.
NB. A shared PTW interface area is one that is jointly administered by both GASCO
and another ADNOC Group Company (such as the Joint Pipeline Corridor).

CHAPTER 3
Page 9 of 42
3.3.5.1
Interface Procedures between Asset Operators/ Area Authorities
Any hot work being conducted within 30 metres of the boundary
between two separate Areas (Habshan) requires the countersignature of
the adjacent Asset Operator (the Area Shift Controller) as well as that
counter endorsement (initial) of the adjacent Area Authority.
For hot work being conducted within 30 metres of the boundary between
two distinct areas within a defined Plant or facility, having different Area
Authorities, e.g. between two separate Process Trains, the counter
endorsement (initial) of the adjacent Area Authority is required.
3.3.5.2
Interface Procedures for ADCO working within GASCO Controlled
Areas
Work by ADCO within GASCO controlled Areas, or within 30 metres of
GASCO Pipelines, requires the use of the GASCO PTW System.
The GASCO Asset Owner (the Plant or Pipeline Vice-President,) should
have an updated list, from the ADCO Division Manager, of ADCO
personnel who are Authorised signatories under the GASCO PTW
System having satisfied GASCO Competency requirements.
Prior to work commencing, the Issuing Authority (Asset Operator) is to
jointly visit and check the work site with the ADCO Authority to confirm
that all work site precautions required by both Authorities are in place.
The GASCO Permit must be referenced to any ADCO Permit which has
been issued, and which is related to the same work activity. In such
cases, the GASCO Authority is to countersign the Issue Section of the
ADCO Permit or Hot Permit.
The ADCO Authority is to countersign the Issue Section of the GASCO
Permit and any supporting Hot Work Permit(s).

CHAPTER 3
Page 10 of 42
3.3.5.3
Interface Procedures for GASCO working within ADCO Controlled
Areas
All personnel who have to enter areas under ADCO control for monitoring or
checking their equipment must obtain permission from the relevant ADCO
Area Authority. Where GASCO has to work in ADCO controlled areas, either
on their existing plant, on ADCO plant or new construction, they must first
obtain an ADCO PTW.
The ADCO Permit request must be signed and submitted by a GASCO
Permit Originator. The GASCO Permit Originator must meet the equivalent
job grade criteria (minimum supervisory Grade 11) as required by ADCO
PTW procedure. The GASCO Permit Originator must be authorised on a
written list submitted to the relevant ADCO Area Manager by the respective
GASCO Asset Owner (the Plant or Pipeline Vice President) to request work
to be undertaken within ADCO controlled areas.
Prior to work commencing, the ADCO PTW Procedure requires the ADCO
Issuing Authority to jointly visit and check the work site with the GASCO
Authority to confirm that all work site precautions required by both Authorities
are in place. The GASCO Authority (the Asset Operator) is to countersign the
Issue Section of the ADCO Permit or Hot Permit.
The ADCO Permit must be referenced to any GASCO Permit which has
been issued, and which is related to the same work activity. In such cases,
the ADCO Authority is to countersign the Issue Section of the Work Permit or
Hot Work Permit.
3.3.5.4
Interface Procedures for Working in Shared PTW Interface Areas
Shared PTW Interface Areas of GASCO and another ADNOC Group
Company, are those areas specifically designated on maps/ drawings where
both Companies have plant and/ or equipment and where neither Company
has overall responsibility. In general, these areas are commonly where
flowlines and pipeline are in close vicinity to each other or cross (see
Appendix A).

CHAPTER 3
Page 11 of 42
3.3.5.4
Interface Procedures for Working in Shared PTW Interface Areas
(Cont.)
Interface procedures also apply to the Joint Pipeline Corridors when
working in the vicinity of ADCO, GASCO or ADNOC pipelines. Joint
Pipeline Corridors will be bounded by an area 30m either side of the
outmost pipelines.
Within a Shared PTW Interface Areas, including the Joint Pipeline
Corridor, the PTW system of the Company undertaking the work will
apply, i.e. if GASCO, or GASCO contractors, are working a GASCO
PTW will be required; if another ADNOC Group Company is working
then their PTW will be required.
In all cases the work activity and PTW must be discussed with the Asset
Operator of the other ADNOC Company (in ADCO the Area Authority)
sharing the area before the work commences. The other ADNOC
company’s Asset Operator must countersign the PTW prior to issue. All
Permit Signatories authorised to sign/ countersign PTW, within Joint
PTW Interface Areas, must be authorised by the Asset Owner (the Plant
or Pipeline Vice-President,). This is to be on a written list submitted to
the other ADNOC company’s equivalent Asset Owner (in ADCO, the
Area Manager).
Work in the Ruwais Easement Areas is under the control of TAKREER
3.3.5.5
Requirements for Identification of PTW Interface Areas with ADCO
All areas within ADCO’s concession area are designated ADCO
administered areas, except for those areas specifically agreed and
marked up on approved drawings. ADCO PTW procedures and
requirements apply for all parties working within ADCO administered
areas.
Drawings clearly detailing the agreed designated boundaries of ADCO,
other ADNOC Group Company PTW administered areas, and agreed
PTW Interface Areas as specifically referred to in this section must be
available for all sites.
A simplified layout drawing, depicting GASCO/ ADCO PTW Interface
areas is included as a reference in Appendix A at the end of this Chapter.

3.4 RISK MANAGEMENT PROCESS FOR WORK
There are, in general, three types of work activity:
•
Work activities that have had a Risk Assessment previously completed and
recorded in procedures or in Maximo;
•
Work activities that are new or have not been risk assessed, and
•
Work activities that can be covered by individual’s competence, skills and training.
In all cases, the initial Risk Assessment should be undertaken prior to the origination
of the Work Permit and any supporting Permits or Certificates (see Chapter 5). It is the
responsibility of the Maintenance/ Engineering Authority to initiate the process and
record the Risk Assessment
An overview of the risk assessment process for work activities, and its application
within the PTW System is provided in flowchart form in Appendix B at the end of this
section.
The following sections describe, for each of these types of activities, the steps that
must be taken in order to ensure the integrity of the risk assessment process.
3.4.1
Introduction to the Activity Risk Assessment (ARA) Process.
Whenever work has to be undertaken by GASCO, Third Parties or Contractors
on GASCO sites, or in the immediate vicinity of GASCO pipelines, it is
necessary to make a suitable and sufficient assessment of the risks to the
health and safety of employees and others, for the purpose of identifying the
necessary control measures. Practically this involves four basic steps, which
are to:
•
•
Identify the possible hazards associated with the work activity;
•
Introduce control measures (precautions) to prevent or reduce the risks to
a level ‘As Low As Reasonably Practicable’ (ALARP). See 3.4.1.3 for
further explanation and guidance on demonstrating ALARP;
•
Specify recovery measures in case the controls fail.
Assess the consequences of the hazardous event(s) and the likelihood of
their happening, i.e. evaluating the risks arising from them;

3.4.1 Introduction to the Activity Risk Assessment (ARA) Process. (Cont.)
The process of identifying the hazards, evaluating risks and applying controls
and specifying any recovery measures will be referred to as ‘Activity Risk
Assessment’ (ARA). This is shown diagrammatically in Fig. 3.4/1 below.

Figure 3.4/ 1 – The Activity Risk Assessment (ARA) Process
In practice, these steps are not always distinct and many decisions about the
overall process will be taken as part of the Activity Risk Assessment. Completing
the four steps of the ARA will produce risk reduction measures that both prevent
incidents, by reducing the probability of occurrence, and mitigate chronic and
acute effects by reducing the consequences.
3.4.1.1 Assessing the Risks
Assessing risk involves considering how likely it is that each hazard
could cause harm, by considering the threats which may lead to the
release of the hazard, what the consequences could be, and, in some
cases, the potential for the event to escalate.
The extent of any risk assessment will depend on the nature of the
risks, the complexity associated with the activity, and on whether the
risks are well understood. The ARA in the workplace can be as basic as
deciding how to go about doing a task safely for simple routine jobs.
GASCO has developed a Risk Assessment Matrix (RAM) as a tool to
help categorise the risk, based on its consequences and the probability
of the potential consequence occurring (see Appendix C).
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 14 of 42
3.4.1.2 Controlling the Risks
Controlling risk involves eliminating the hazard wherever possible, or
applying measures to prevent the hazardous event and/or the harm
from happening.
In all cases, the extent of any risk assessment and the controls arising
from it should be proportionate to the risks. The higher the risk, the
greater the degree of control required and the more senior the
management level required to approve the activity.
Figure 3.4/ 2 below illustrates that, as the risk increases, the necessary
level of control for the activity can be achieved by adding controls or by
strengthening existing ones.

CHAPTER 3
Page 15 of 42
3.4.1.3 Demonstrating ALARP
ALARP means to reduce a risk to a level, which is as low as
reasonably practicable. This involves balancing reduction in risk
against the time, trouble, difficulty and cost of achieving it. This level
(ALARP) represents the point, objectively assessed, at which the time,
trouble, difficulty and cost of further reduction measures becomes
disproportionate to the additional risk reduction obtained.
A key concept in identifying the ALARP level is to ensure that all
possible options for risk reduction have been identified. It is often the
case that only the obvious or easy options are considered. It is
important, however, to look at all options even if at first they appear
difficult or costly.
The Risk Assessment Matrix (RAM), (see Appendix C) is a tool that
provides a standard approach to the qualitative assessment of risk. All
activities, which fall in the yellow (medium) or red (high) sectors of the
RAM, require documented evidence that they have been reduced to
ALARP. An Activity Risk Assessment (ARA) form is provided for this
purpose (see Appendix E).
Specific guidance on the completion of the ARA form is given in 3.4.3,
Stage 6, and Appendix D.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 16 of 42
3.4.2 Performing an ARA for Previously Assessed Activities
Most activities that are undertaken are not new, they are routine, or common
tasks that have previously been risk assessed and/ or are covered by existing
procedures. They have probably been developed through established good
practice and with due consideration for the hazards that may be present.
Such activities do not need a new risk assessment each time they are carried
out, but do require that the assessment is subject to periodic review, primarily
to identify if anything has changed that would affect the outcome of the
assessment.
Some questions, which should be asked, are, for example:
•
Have the persons doing the activity changed and are any new persons
competent?
•
•
Have new hazards been introduced?
Are new tools being used or new procedures introduced?
If new controls are identified then the Permit Originator should update the ARA
and the date of the review should be recorded.
3.4.3 Performing a New Activity Risk Assessment
This section describes the steps required to perform a risk assessment for an
activity, or combination of concurrent activities, which have not been previously
assessed. This process should also be used if a previously assessed routine or
common task has been reviewed and the risk assessment found to be not
appropriate for the particular job.
When a new risk assessment is performed, all hazards and threats should be
identified and the risk assessed such that controls can be identified to reduce
the risk to ALARP (see 3.4.1.3). If the risk cannot be reduced to ALARP, the
activity should be redefined or not undertaken.

3.4.3 Performing a New Activity Risk Assessment (Cont.)
Stage 1:
The Originator will Identify and form the ARA Team.
The ARA is normally conducted within the Department responsible for doing
the activity and should include personnel who are:
•
•
Responsible for the task;
•
Have sufficient knowledge, expertise and competence in the activity to be
performed to have an understanding of the hazards it presents;
•
•
Knowledgeable about the location, and the hazards that are present;
Competent to conduct an ARA;
To be Involved in carrying out the task.
The ARA should be undertaken prior to origination of the permitry. Where
appropriate, the team should visit the worksite. The activity can be broken
down into a number of smaller tasks where it is considered necessary.
Stage 2.
Identify the Hazards and Effects.
Each task is to be studied to identify the hazards, hazardous events and
potential incidents whether they arise from the actions of people or from the
conditions surrounding the activity.
The assessment should identify who or what might be harmed and the findings
recorded.
Stage 3.
Identifying Risk Ratings for Initial Risks
Risk rating is a means whereby the risks associated with a particular hazard or
hazardous activity can be expressed as a value and compared with acceptable
limits.
The initial risk rating should be assessed on the situation that prevails before
any controls are implemented for each hazard. The Risk Assessment Matrix
(see Appendix C) should be used to calculate risk ratings.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 19 of 42
Stage 4.
Identify Control and Recovery Measures.
Taking each hazard in turn, the ARA team should develop ways to either,
eliminate the hazard or provide appropriate control and recovery measures to
mitigate them. In practice, a mixture of different controls often produces
effective control, e.g. engineering controls, personnel protective equipment
and procedures.
Stage 5
Review Residual Risks.
The residual risk is any risk that remains after all the control measures are
applied.
The Risk Assessment Matrix (RAM) should again be used and the results
entered in the ARA Worksheet. The residual risk should be ALARP (see
3.4.1.3).
Stage 6
Document and Record.
The ARA should be recorded using the ARA Worksheet. A copy of the ARA
Worksheet is included in the Appendices (see Appendix E). An annotated
version of the ARA is also provided in Appendix D, which provides guidance on
its completion.
The ARA Worksheet can be used to:
•
Communicate the outcome and actions to those responsible for
implementing the control measures and performing the activity
•
Ensure the information is available to others who may have to perform the
activity.
3.4.4 Activities covered by Individuals Competence
It is recognised that some low risk activities are adequately covered by the
competency and skills of the individual. Therefore, where a formal risk
assessment would not produce any significant findings it is not necessary to
formally record the risk assessment.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 20 of 42
3.4.5 Responsibility for ARA process
The Plant and Pipeline Vice-Presidents are responsible in their respective
areas for the ARA process as described in 3.4.1. In addition, for certain
activities, they are personally responsible for approving the ARA where there is
a higher level of initial risk, such as, (though not exhaustive):
•
•
•
•
Hot tapping on live hydrocarbon process streams
Disjointing and/ or spading on live flare lines or lines containing H2S
Confined space entry in oxygen deficient or toxic atmospheres
Heavy lifting operations over live hydrocarbon process lines
It is the responsibility of the Area Superintendent to bring such high-risk
activities to the notice of the Plant/Pipeline Vice President
3.4.6 Linking the ARA and the Permit to Work
This section should be read in conjunction with the Work Permit (see Chapter
5, Section 5.1, Fig. 5.1).
A matrix diagram, which provides an overview of the Work Permit Lifecycle
versus Signatory Responsibilities, is provided in Appendix F.
Before work commences following the ARA, authorisation must be obtained
through the Permit to Work system by issuing a Work Permit together with any
necessary supporting documentation.
The Work Permit has a number of consecutive steps that are all part of the
overall Risk Management process and are in addition to the ARA. These steps
are as follows:
STEP 1 Work Description and Risk Assessment
Following completion of the ARA, the person who is requesting the work, the
Originator, has to describe what work is to be done and what equipment is to
be used. The work scope must be clearly defined in order that the persons
undertaking the worksite preparations are clear as to the intent.
The results of the ARA are also recorded on the Permit in terms of the hazards
associated with the work and the controls necessary during its execution.
Where the work activity covers several tasks, or is of a more complex nature
requiring sequential controls, with different persons responsible for individual
tasks, an Activity Sequence Control Sheet (ASC) should be completed (see
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 21 of 42
Chapter 6) and submitted with the permitry.
One of the controls to be specified is the requirement for the supervision of the
work, defined as the Person in Charge of the Worksite (PICWS). The level of
supervision (the category of worksite presence required) should be appropriate
to the risk of the job being undertaken.
The category of worksite presence is defined as follows:
Category A:
Continuous attendance of the PICWS, with signed transfer of
responsibility when one PICWS is replaced by another. Work MUST
stop when no PICWS is present. The PICWS is not to hold any other
Permit whilst nominated as a Category A, PICWS presence.
A Hot Work - Category 1, Permit and other designated high-risk jobs
(e.g. Vessel Entry) would normally require a Category A presence.
Category B:
As Category A, but work may continue during short (e.g. not more than
45 minutes) absence of the PICWS. One person cannot be responsible
for more than one Permit when nominated as a Category B, PICWS
presence, unless the other Permit is in close proximity to the first one
and can be safely supervised by one person.
Category C:
The PICWS is to make an initial visit, and is then required to make only
periodic visits to the worksite. The number of Permits, with a Category C
PICWS presence, which can be held by one PICWS, should be limited
to a maximum of six and is further dependent on the PICWS ability to
provide adequate supervision for all Permits under his control.
As a guideline, each worksite should be visited by the PICWS at least
three times during a shift/ normal work period.

Page 22 of 42
STEP 1 Work Description and Risk Assessment (Cont.)
Supporting documentation may also be originated at the same time as the
Permit because the Risk Assessment Process (ARA) may also have identified
particular hazards introduced by the work, which require further formal
controls. Examples are:
•
•
The introduction of risk due to hot work
•
Use of radioactive sources.
Confined space entry
Where such risks are identified, then Supporting Permits or Certificates are
needed. These are listed in Table 3.4/ 1 for specific activities and provide the
mechanism for defining the controls required.
Illustrations of all Permits and Supporting Certificates are given in Chapter 5,

STEP 2 Permit Review and Validation
Following the origination stage of the Permit, it is necessary to present the
Permit to Operations (the Asset Operator) so that agreement can be reached
with respect to the timing of the work. This is normally done at the daily Permit
to Work meeting.
This PTW meeting is the forum for Maintenance/ Engineering and Operations
to review all new permitry submitted for work that has been agreed as
necessary in the Maintenance/ Engineering Work Plan. It is here that any risk
assessment which has been previously undertaken (as described under 3.4.1)
and which requires submission of a formal Activity Risk Assessment sheet is
discussed, and further elements of the overall Risk Management process are
developed. Because of the importance of this daily PTW meeting it is described
here in more detail.
At weekends, or where permitry is not submitted via the daily PTW Meeting, the
Asset Operator and Authorised Maintenance/ Engineering Authority must
undertake the process of reviewing and validating of permitry.
DAILY PTW MEETING*
Objective:
(i)
To provide a daily overview of all ongoing and planned work under the
control of the Permit to Work System and to identify any potential
conflicting activities.
(ii)
For Operations to review and agree new Permits, including any Activity
Risk Assessments previously undertaken, time scales and resource
requirements.
Note that the daily PTW meeting is not the forum for undertaking the ARA.
(iii) To provide an effective handover mechanism to duty shift teams through
the recording of work that is to be undertaken in the Operations Area.
(iv) To provide a Maintenance/ Engineering and Operations interface for
Permit to Work requirements.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 25 of 42
3.4.6 Linking the ARA and the Permit to Work (Cont.)
DAILY PTW MEETING*
Attendees
As a minimum, the daily PTW Meeting will be attended, by the Operations
Coordinator, who will normally be the Chair Person, Shift Controller (as
available) and appointed Maintenance / Engineering staff.
Further attendees, for example Technical Support and/ or HSE, will be present if
requested by the Operations or Maintenance/ Engineering attendees, when it is
recognised that further expertise or advice is relevant.
Terms Of Reference
(i)
The meeting will be held daily, taking into account weekend working.
(ii)
Key input mechanisms to the daily PTW Meeting will be work details/ status
of ongoing work and any new activities. Any preparatory requirements for
new activities should be highlighted.
(iii) As far as is possible/ practicable, all new Permits should be processed
through the daily PTW meeting, unless it is HSE or production critical and
cannot wait. In such cases, Permits may be processed outside of the PTW
Meeting, but the Maintenance/ Engineering Authority and the Asset
Operator must still adhere to the same review and validation process.
(iv) Permitry must be submitted with adequate advance warning to allow
Operations the required timescale for detailing and recording of isolation
procedures and for equipment preparation.
A check must be made to ensure that there is no foreseen conflict, both
geographically (i.e. across other work boundaries) or on a time basis (activities
which may start later). This is to be done by the Asset Operator.
Once the permitry has been discussed at the daily PTW Meeting and controls
agreed, the Permit can be VALIDATED, that is, accepted by the Asset Operator
as an agreed piece of work that has been risk assessed and is to be undertaken
in an area controlled by Operations (or for Unrestricted Areas the appointed
Asset Operator).
* Pipelines Division may hold the meeting at a lesser frequency, as workload
requires but not less than weekly

STEP 3 Permit Issue
When the worksite preparations are complete, and any additional Permits/
Certificates prepared, the final stage of the authorisation process can take
place, that is, the ISSUING of the Permit.
It is important to note, however, that although the Permit is issued, work may
not start until all of the necessary Permits are accepted and endorsed (see
Steps 4 & 5).
STEP 4 Permit Acceptance
The person responsible for the work activity ACCEPTS the Permit. This is the
Person who will be, or will hand over to, the Person In Charge of the Work Site
(PICWS) and he must arrange any necessary Toolbox Talk(s).
The Toolbox Talk is the last step in the Risk Management process and is the
final opportunity to discuss the hazards and controls with the persons who will
execute the work. Generally speaking, a Toolbox Talk is required for all
activities undertaken under a Permit, although for routine, lower risk, activities
need not necessarily be formally recorded.
Guidance notes on undertaking Toolbox Talks is given in Chapter 7, which
includes an example of a Toolbox Talk record sheet.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 27 of 42
3.4.6 Linking the ARA and the Permit to Work (Cont.)
STEP 5 Worksite Responsibility
The PICWS must now sign the Permit to demonstrate that he understands the
hazards of the work and the controls necessary. He has the responsibility for
making sure everyone in the work party understands his particular role in the
work, and that they understand the relevant hazards and the required controls.
Should the PICWS change, or there be more than one PICWS, e.g. if there are
different shift teams, the same criteria of accepting responsibility apply.
STEP 6 Endorsements for the Continued Safety of the Worksite
6.1 Initial Endorsement
The Maintenance/ Engineering Authority, who has accepted the
Permit, must take it to the worksite and obtain the endorsement of the
Area Authority that it is safe for the work to start. This is a control as it
gives the Area Authority the opportunity for a further discussion of the
work and to identify any activities in the area, which may conflict with
the work.
The Permit is then endorsed by the PICWS, who accepts
responsibility for the worksite prior to work start, and is the final
opportunity to discuss the work prior to its commencing.
Once all parties have initialled for work start, the Permit is now
ENDORSED.
6.2 Recording of Work Stop
When work has stopped at the worksite, normally at the end of the
Maintenance/ Engineering work period, this is recorded on the Permit
by the PICWS. Once the PICWS has initialled for Work Stop, the
Permit is termed as SUSPENDED.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 3
Page 28 of 42
STEP 6 Endorsements for the Continued Safety of the Worksite (Cont.)
6.3
Permit Re-endorsement
At the start of each new shift, a further re-endorsement is required by:
i)
The Asset Operator to confirm there is no conflict with any other
activity;
ii) The Area Authority to confirm that there is no change to worksite
conditions;
iii) The PICWS to accept responsibility for the continued safety of the
worksite.
STEP 7 Permit Closure
When work has been completed, or requires Permit renewal, the
CLOSURE portion of the Permit must be completed.
In particular, when work has been completed or will lapse for an
extended period, but isolations must remain in force, it is important
that the controls associated with the isolations remain valid. Such
controls must be visibly continued and displayed in the PCF.
Once the PICWS has initialled the Closure portion of the Permit it is
now termed as CLOSED.
3.4.7 Visibility of Permits
As part of the Risk Management process, Permits must be displayed in a
systematic arrangement, clearly showing work in progress or work suspended,
for each defined Operating Area. The display should be at a suitable Permit
Control Facility (PCF) (see Chapter 8). Management and Operations staff can
therefore readily see the activity status for all work subject to the PTW system.
Included in Chapter 8, Appendix A is a simplified flowchart showing the various
stages in the Permit lifecycle and how the continued safety of the worksite is
managed and administered.

CHAPTER 3
Page 29 of 42
3.4.8 Layout and Colour of Permits
References should be made to Permit and Supporting Certificate examples,
Chapter 5, Figure 5.1 through to Figure 5.8.
The Work Permit is designed as a double A4 format to provide a sequencing of
signatures as the Permit passes through its various stages.
The Work Permit is the core the PTW System and is the only Permit which can
be 'stand-alone'.
Supporting Permits and Certificates are designed to identify specific hazards
and controls, additional to those recorded on the Work Permit. A Work Permit
MUST accompany all supporting Permits and Certificates.
For visibility purposes, and to aid identification of documents, different colours
are used on the border of Permits and Certificates as per Table 3.4/ 2 below.

The second copy, which has a yellow coloured background, is retained in
the Permit Control Facility.
3.4.9 Permit Signatories
3.4.9.1
Authorised Permit Signatories
The key steps of Validating, Issuing, Accepting and Endorsing of
Permits is done by Persons who have been assessed as competent
to execute the Risk Management Process associated with these
separate steps.
Certain activities, namely those that require supporting Permits, have
a higher level of risk and consequently higher levels of authorisation
exist.
Permit Signatories are those who have had sufficient training and
experience and have been duly authorised as those Permit
Signatories by Plant and Pipeline Vice-President.
The Authorised Signatories, who are responsible for signing the
various sections of the Work Permit and Supporting Permits or
Certificates, are tabulated in Table 3.4/ 3.

3.5 RULES GOVERNING PERMITRY
3.5.1 Permit and Certificate Validity Periods
To ensure that precautions required for tasks of a long duration are
reviewed regularly, limits are set on the validity periods that Authorised
Permit Signatories may set for Permits. These are:
Work Permits.....................................
7 consecutive (calendar) days.
Hot Work Permit, Category 1 & 2……
7 consecutive (calendar) days
Radiation Permits...............................
24 hours
Isolation Confirmation Certificate.......
No Validity period
Excavation Permit..............................
28 consecutive (calendar) days
Confined Space Entry Certificates…
28 consecutive (calendar) days
Gas Test Certificate…………………
No Validity period
Pipeline Authorisation to Work (ATW)… 28 consecutive (calendar) days
(max. extension of 3 x 28 days)
3.5.2 Permit Endorsement Periods
The maximum endorsement period for Permits, supporting Permits and
Certificates is 12 hours. An endorsement may not straddle an Operations
Shift change. Where a shorter endorsement period is required, a
statement in the 'Particular Hazards and Additional Precautions' section
of the Permit should indicate where this is required.
Pipeline ATW Forms have endorsement periods but are subject to
worksite checks by the Area Authority on a frequency defined by the Asset
Operator (see Chapter 5, Section 5.9.4).
3.5.3 Maximum Number of Permits
In normal circumstances, there should be a sensible limit on the
maximum number no of Permits to be administered and issued by the
Asset Operator and each Area Authority on a shift basis. Guidelines for
the maximum number of Permits are given in Table 3.5/ 1 below.
Preferably, the number of Permits should be managed below these
recommended figures.
GASCO Permit to Work Standard

The recommendation covers only the numbers of Work Permits and Hot Work
Permits to be managed, and does not take account of any other supporting
Permits or Certificates issued.
In other circumstances, e.g. during major shutdowns when Permit requirements
are greater, special arrangements for the control and administration of Permits
should be made and agreed with the Plant or Pipeline Division Manager.
At the daily PTW meeting, the Asset Operator should review the current number
of Permits per operational area prior to accepting new Permits. Any increase
beyond these criteria should first ensure that the quality control, safety and
individual responsibility is not compromised.
3.5.4 Stoppage of Work Following an Alarm
All work is to cease immediately on initiation of any Plant alarm or advised
change of Plant status away from normal by the Area Authority or Asset
Operator.
On the re-establishment of normal status, the PICWS is to obtain the verbal
authorisation of the Area Authority before restarting work except where there
has been an escape of H2S when the Permits issued in H2S zones must be
re-endorsed.
For Hot Work activities, or where there has been an escape of H2S, the PICWS
is to return the Hot Permit to the Permit Control Facility for subsequent
re-endorsement of the Asset Operator before restarting work.

3.5.5 Changes to Work Details on a Permit
If changes are required to the work details on any Permit prior to the Work
Permit validation, the Originator must initial them. If changes are required
after the Work Permit validation, they are to be initialled by the Originator
and the Validating Authorities (the Asset Operator and Authorised
Maintenance/ Engineering Authority).
Precautions and controls may be added to, but not deleted from, a Permit.
These should be agreed with the Validating and Issuing Authorities prior
to making changes on the Permit details. All Permit signatories must then
initial against the agreed changes.

Assess the POTENTIAL CONSEQUENCES of the hazard for each of the four categories (People, Assets, Environment, Reputation)
Assess the PROBABILITY of these POTENTIAL CONSEQUENCES occurring for each of the four categories (People, Assets, Environment,
Reputation)
Classify the risk on the matrix for each of the four categories (People, Assets, Environment, Reputation) from the intersection of the chosen row
(POTENTIAL CONSEQUENCES) with the chosen column ( PROBABILITY)
In order to document the risk classification, first record the PROBABILITY (A - E), then the POTENTIAL CONSEQUENCES (1 - 5), and finally the
category to which the classification applies (People = P, Assets = A, Environment = E, Reputation = R ), for example C3P.
Based on the risk classification, identify and implement appropriate remedial action for each of the four categories (People, Assets, Environment,
Reputation) as indicated below:
•
LOW risk – manage for continuous improvement
•
MEDIUM risk – demonstrate that the risk is at a level that is as low as reasonably practicable (ALARP)
•
HIGH risk – take action to reduce the risk to a level that is as low as reasonably practicable (ALARP)

CHAPTER 4
WORKSITE PREPARATIONS
4.1 INTRODUCTION
Once the hazards associated with a particular job have been identified, it will be
necessary to consider how they can be separated or isolated from the equipment or
plant to be worked on. Flammable, toxic, pressurised, high temperature, or low
temperature fluids will normally have to be removed from the isolated plant before
working on it.
An essential ingredient of any Safe System of Work is the integrity of the isolation
procedure. Whilst the Work Permit identifies the isolation requirements it does not
provide the specific isolation details. These are to be documented and appended to
Permits as per existing, Plant specific, Isolation and re-instatement procedures.
All sites must ensure that the latter are controlled in accordance with specified
standards. These should be in compliance with the following.
4.2 STANDARD OF ISOLATION
4.2.1 Isolation Requirements
In general, Plants are built with isolation provisions an integral part of the design
(for example, DGS-0000-020) with the basic premise that the isolations prevent
leakage. In case this premise in practice is not confirmed additional controls are
required to manage risk to As Low As Reasonably Practicable
There are two main methods of isolation:
a) Positive isolation.
There are specific situations where positive isolation is required such as
Confined Space Entry and Hot Work with a Naked Flame. This means
incorporating the use of spades, spectacle blinds, or removable spools and
blind flanges. Spades and blinds must be fully rated; use of thin blinds must
be with site management approval. Positive isolations must be at the closest
point possible to the work.
b) Valved isolation
Under less hazardous situations a valved isolation may be applied:
i)
Double Block and Bleed.
•
Breaking of the hydrocarbon or toxic gas envelope should be against a
double block and bleed with the tightness of the isolation confirmed by
testing. Residual pressure must be zero at the work location.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 4
Page 2 of 10
•
If the breaking of the hydrocarbon or toxic gas envelope has to be done
against a single isolation valve a risk assessment is required involving as a
minimum Superintendent level. Tightness of the isolation must be confirmed by
testing and if not 100% tight, additional barriers are required.
ii) Single valve isolations
Single valve isolations may be used for less hazardous materials e.g. water and nitrogen.
•
When work is to be undertaken which requires isolation of equipment a formal
written scheme of isolation must be prepared with isolations documented on the
Isolation Confirmation Certificate The isolations must provide control of all
hazardous energy sources within the defined system and/or equipment isolation
boundaries including electrical power, process fluids, hydraulic, pneumatic,
thermal, chemical and mechanical systems. Where appropriate (e.g. where there
are no tag numbers or where the isolation is complex), a P&ID showing the
isolations must accompany the isolation procedure.
4.2.2 Establishment of Isolation Boundaries
The Operations Superintendent is responsible for ensuring that a comprehensive
suite of documented procedures is in place, which define the mechanical
(process) system isolations for all plant and equipment.
The Maintenance Superintendent is responsible for ensuring a comprehensive
suite of documented procedures is in place, which define the electrical and
instrument Isolation boundaries for plant equipment.
The Shift Controller is responsible for the authorisation of the isolation of
equipment to be worked on, and any action necessary to prepare the equipment
for safe working, such as de-pressurising or purging. He is also responsible for
the authorisation of de-isolations on completion of work.
4.2.3 Control of Equipment Preparation
The preparation and isolation / de-isolation of equipment can introduce particular
hazards. The Shift Controller must ensure that controls are in place to manage the
risks associated with these hazards at each step of the preparation, isolation and
de-isolation process.
4.2.4 Documentation of Isolations
4.2.4.1 Mechanical and Instrument Isolations
Where isolations form part of the preparations for work, there must be a clear
description of the isolation procedure, including a detailed list of all items (e.g.
valves, spades, blinds, pipework removed, blank flanges fitted, vents and
drains opened, breakers racked out, etc.), utilised in the isolation. These are
to be documented on the Isolation Confirmation Certificate
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 4
Page 3 of 10
Where appropriate (e.g. where there are no tag numbers or where the
isolation is complex), a P&ID showing the isolations must accompany the
isolation procedure.
The Isolation Confirmation Certificate together with any P&IDs used to
show isolations, must be kept in the PCF with the copies of the relevant
Work Permits.
Any changes to the isolation procedure or isolation boundaries are to be
approved and initialled, after the relevant section of the procedure, by the
Maintenance/ Engineering Authority and the Shift Controller. This should
be done prior to making any change in the isolation.
4.2.4.2 Electrical Isolations
The document for recording electrical isolation and de-isolation
operations, for the purpose of the PTW System, shall be the Isolation
Confirmation Certificate. (See Chapter 5, Section 5.7) The use of any
Sub-Station/ Switching Logs and Switching Programmes required for by
the Electrical Safety Rules, to record isolations and de-isolations, are
additional to the PTW System requirement.
The only exception to the rule that specifies the need for an Electrical
Isolation on an Isolation Confirmation Certificate to be raised is when an
electrical isolation is required for low voltage (<50 volts) electrical work.
An Electrical Person, having the required level of competence, may carry
this out providing he has been duly authorized by the Senior Electrical
Engineer to undertake this type of work.
4.2.5 Master Isolations
A Master Isolation may be used to establish isolation boundaries for major
tasks, which encompass more than one process system and/or piece of
equipment. This is so that a number of tasks can be undertaken within a
single boundary. Recommended standards for controlling work under A
Master Isolations are as follows:
(i) Each Master Isolation Boundary should be clearly defined in a written
procedure. The specific isolation details covered in the procedure should
indicate the isolated and de-isolated position of each isolation device and
the equipment and/ or system affected.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 4
Page 4 of 10
The Operations Co-ordinator has the responsibility for approving this procedure.
Final authorisation for its use rests with the Operations Superintendent.
(ii) Control of the Permits in use within the boundary is to be maintained by the
Shift Controller.
(iii) When a Master Isolation is in place, the Shift Controller is to ensure that all
Permits in use within the boundary have been closed out before the Master
Isolation integrity is compromised, i.e. prior to allowing any de-isolations to be
undertaken.
4.2.6 Minor Mechanical Isolations
The recording of isolation details is not mandatory for Small Bore Instrument
Mechanical Isolations carried out by an Instrument Person, assessed to the
required level of competence, provided ALL the following conditions are met:
(i) The work is minor routine maintenance work, i.e. work that is considered to
present no more risk than that associated with achieving a physical
isolation;
(ii) A Work Permit exists to cover the work, endorsed by the Shift Controller and
Area Operator;
(iii) The isolations are listed on a suitable document to the satisfaction of the
Shift Controller;
(iv) The isolations are of such a minor nature that they will not degrade the
integrity of any Safety/ Emergency System;
(v) The work to be done under the isolation will be undertaken by the person
who applied the isolation, who will not leave the worksite whilst the isolation
is in place. If the isolation is to remain in place beyond a single shift, then the
isolation details must be recorded and the isolation points secured and
labelled.
(vi) The isolation does not form part of an isolation boundary for other work;
4.3 PHYSICAL SECURING AND TAGGING OF ISOLATIONS
4.3.1 Requirements for Securing Valve Isolations
Valves require to be immobilised in such a manner that they cannot be
inadvertently operated. In this case the interference with the isolation will be
immediately obvious.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 4
Page 5 of 10
4.3.1.1 Immobilising Devices
The range of valves fitted on GASCO facilities would require a number of
different methods of Immobilisation. Some valves may already have fixed,
immobilising devices fitted, e.g. Castell Locks, Ellis Locks, etc. As it is not
practical to provide such devices for all valves, the recommended method is to
use simple securing mechanisms with locking and tagging.
4.3.1.2 Securing, Locking and Tagging
Multi part labels, as shown below, are to be utilized to identify isolation and
break points. Each Vice President for Plant and Pipelines is responsible for
developing detailed procedures for the labels.
a) Securing
Valves and other isolation devices required to be physically secured in such a
manner that they cannot be inadvertently operated without destroying the
securing mechanisms (e.g. chain and lock arrangements). The preferred
method is to use Red and white high strength polycarbonate chain. This has
good visibility, is easily handled and secured, and is sufficiently strong to provide
adequate integrity of the isolation.
b) Locking
A tamper-proof seal to be used to lock the securing mechanism or where
appropriate to directly lock the immobilizing device in position is the nylon Grip
Rip seal
c) Isolation Tagging
A visible Isolation Tag (see Fig.1) is to be used for valve isolations which is:
a)
Made up of material which cannot be torn off easily.
b)
Red in colour printed with a unique number on each of 3 parts part so that
the stubs and counterfoils can be kept with isolation details in the PCF
when the label is attached to the isolation point.
c)
Capable of being written on with a permanent marker.
d)
Fitted with large secure eyelet to enable the sealing device to fit through
it, thus making it an integral part of the securing arrangement.
e)
Identified with the Work Permit number related to the isolation, and the
Labels own unique serial number on all the three parts of the label.

Spade and Blank insertion is generally the preparatory activity for other work
and is identified in the approved Method Statement supporting a Work Permit
and Isolation Confirmation Certificate
To assist in the identification of spading points, and to identify the spacers that
may be removed when a spade is fitted; a blue spade location tag is attached to
the spading point at the planning stage (see FIG.3). When the spade is fitted,
the Blue tag is attached to the removed spacer. This ensures the spacer is
refitted into correct location. Spade location tags do not have stub and
counterfoil portions.
!
Figure: 3
d)
Re-instatement of Process Line-Breaks
All flanges/joints above 10” that have been ‘broken’ by Maintenance Department
are required to be torqued /tensioned. These are to be positively identified in order
to record the location, re-instatement and final pressure testing of the joint.
Operations will maintain a ‘Joint Broken’ register in the to control room and record
compliance to these requirements. A unique 3-part, multi-colored, Joint Assembly
Tag, is to be utilized for this purpose (see Fig.4)

Figure: 4
4.3.1.3 Common Isolations
Where a single valve is used as isolation for more than one isolation boundary,
a tag label relating to each Work Permit is to be applied to the device. In this
situation the securing device fitted SHALL NOT be removed until the last
isolation label applicable to the valve or spade is removed.
4.4 LOSS OF ISOLATION RECORDS
Where isolation is found with some, or all, of its documentation missing, an
investigation will be required before the isolation can be removed. The following
procedure should be followed:
(i) The Shift Controller is to double-check the Permit, in the PCF and the archive
for the relevant documentation;
(ii) The Area Authority is to carry out an onsite check of the system against a P&ID
for any other isolations, for valves not in their normal operating position, or
breaks/open ends in the system;
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 4
Page 9 of 10
4.5 EXTENDED PERIOD ISOLATIONS
Extended Period Isolations (EPI's) are isolations, which are required to remain in
place although no work is being carried out within their boundary. They may be
required for two main reasons
(i) Where work has commenced but is, or is likely to be, suspended for a period
exceeding the validity period of the Work Permit, for example, when awaiting
spares for a repair;
(ii) Where an item of equipment becomes redundant and is to be isolated pending
a Plant Change Proposal to remove it or provide a more permanent means of
isolation.
4.5.1 Documenting of EPI's
The procedure for the documenting of EPI’s is as follows:
(i) The Shift Controller is to record the EPI in an EPI Register in the PCF. The
white copies of the Work Permit and the Electrical Isolation Certificate and/
or other isolation details are to be retained in the EPI section of the Permit
Rack in the PCF.
(ii) When it becomes possible for work to restart within the EPI boundary the
Originator is to raise a new Work Permit. The isolation details are then to be
attached to the new Work Permit, and handled by the Originator in the
normal manner.
(iii) The Shift Controller will record the fact that the EPI has been cancelled in
the EPI Register.

CHAPTER 5
COMPLETION OF THE WORK PERMIT, SUPPORTING PERMITS AND
CERTIFICATES
5.1 COMPLETION OF THE WORK PERMIT
This procedure should be read whilst referring to the Work Permit (see Chapter 5,
Figure 5.1). The responsibilities of the Permit of Work Signatories are explained in
Chapter 2, Section 2.2.
5.1.1 Work Description and Risk Assessment
The work order number should be entered into the space provided
Box 1a. Identification of the Task and its location
Permit Originator is to enter:
•
An overview of the task so that is easily visible from the Work
Permit’s slot position in the Permit display rack, and the date that the
Work Permit is required;
Box 1b. The Originator enters the Location/ Tag number and Area/ Worksite in
order to clearly identify the equipment and area where the work is to
take place. The Originator ticks the Boxes relevant for the Area (and if
he does not know, then the Asset operator will tick the boxes).
Box 2
Work Description and Equipment
The Originator is to describe the work in summary form but containing
sufficient detail so that appropriate worksite preparations can be made.
Any special equipment to be used, especially where it may introduce a
threat or hazard, is to be entered. Reference may be made to
engineering method statements and if this is the case the engineering
method statement should be attached to the Permit.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 5
Page 2 of 45
Box 3
Particular Hazards and Special Precautions
When the Originator undertakes the Activity Risk Assessment (ARA)
process and subsequently the review with the Validator, hazards may
be identified that require to be highlighted on the Work Permit.
Provision is made for this in Box 3.
Whenever a protective function is being disabled or a Safety/
Emergency system being isolated, it is mandatory to enter in Box 3 the
controls necessary to prevent escalation should a hazard be released.
The Originator will also enter the category of worksite presence by the
PICWS, after agreement with the Asset Operator during the PTW
Planning Meeting. This is a worksite control.
Box 4
Worksite Supporting Documents
Box 4a The Originator enters the reference number of any supporting Permits
or Certificates required as a result of the ARA process These
supporting documents will accompany the Work Permit when
presented to the daily PTW meeting, or, where the work is of an urgent
unplanned nature, directly to the Asset Operator.
Box 4b The Originator enters the reference number of any related Work
Permits including the Trade that the related Work Permit has been
issued to. Where the Work Permit is a continuation then the previous
Work Permit reference number is also entered.
Box 4c The Originator is to tick the relevant Boxes for any other supporting
documentation that is to be submitted with the Permit.
Box 5
Specific HSE Requirements
The Originator will tick the relevant Boxes in the ‘required’ column of
Box 5 thus indicating the HSE equipment/ resources necessary as
precautions for the work. These will have been identified during the
Activity Risk Assessment step
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 5
Page 3 of 45
Box 6 Work Permit Originator
The Originator completes Box to signify the end of the origination steps.
It should be noted, however, that the subsequent Permit review,
Validation and Issue steps might identify a need to add to Boxes 3, 4 or 5.
If this is the case, the Originator must initial any such change to signify
that he is aware of them and accepts them.
5.1.2 Permit Review and Validation
Box 7 Worksite Preparations
When the Work Permit is presented to Operations, the Asset Operator
(Operations Co ordinator or his deputy) will decide what preparation and
isolations are to be made on the equipment (refer to Chapter 4, Worksite
Preparations) and tick the required Box.
When the preparation is complete the Area Operator or Assistant Shift
controller will initial the check Box.
In the case of Protective Function Disable or Safety Systems isolations,
the Asset Operator ticks the requirement in Box 7. The Shift Controller
records the detail in the Trip and Safety System Defeat Register, which is
held in the Main Control Room, when the protective function is disabled.
Box 8 The Maintenance/ Engineering Authority completes Box 8. When more
than one Maintenance/ Engineering Authority is involved, the
Maintenance/ Engineering Authority who signs does so on behalf of the
others and assumes overall responsibility for the permitry aspects.
Box 9 The Asset Operator (the Operations Co-ordinator or Shift Controller)
completes Box 9. This validation step is normally completed at the Permit
Planning Meeting when the Activity Risk Assessment (ARA) is reviewed.
The Asset Operator then sends the Validated Work Permits to the PCF for
display in the Validation slot of the display rack.
GASCO Permit to Work Standard

CHAPTER 5
Page 4 of 45
5.1.3 Permit Issue by Operations
Box 10 Once it is confirmed that:
(i). The worksite preparations are complete, and
(ii). There is no conflict with any other Work Permit or work activity.
The Shift Controller completes Box 10.
(If the work requires any type of isolations, then ICC certificate must be
completed prior permit issue).
When the work involves an interface activity (defined in Chapter 3,
Section 3.3.5) or the work involves a higher degree of risk (see
Chapter 3, Section 3.4.3) then a countersignature is required, by the
other Asset Operator or the Asset Holder, in the space provided in Box
10.
5.1.4 Permit Acceptance by Maintenance/Engineering Authority
Box 11 The Maintenance/ Engineering Authority accepts the Permit from the
Shift Controller and completes Box 11.
5.1.5 Worksite Responsibility
Box 12 The Maintenance/ Engineering Authority will enter the name of the
Person in Charge of the Worksite (PICWS) in Box 12(a). The PICWS
will sign to acknowledge he understands his responsibilities after Area
Authority endorsement at the worksite.
Normally the PICWS will remain in charge for the duration of the job,
but to cater for a change in the designated PICWS, extra spaces are
provided in Box 12(b). Also if there is more than one designated
PICWS, e.g. to cater for shift working, then the name of the additional
PICWS should be entered in Box 12(b). In both cases the PICWS must
sign Box 12(b).
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 5
Page 5 of 45
5.1.6 Endorsement for the Continued Safety of the worksite
Box 13 The Maintenance/ Engineering Authority will take the top (white) copy to
the worksite for endorsements in Box 13 by the Area Operator and
PICWS. The PICWS will display the Permit at the worksite. (Note for
Pipelines the endorsement may take place in the PCF)
The 2nd (yellow) copy is retained in the Permit Control Facility and
visibly displayed by the Shift Controller, or Assistant Shift Controller, in a
slot in the Endorsed section of the display rack.
At the end of the Engineering work period, the PICWS initials the space
in Box 13 (Work Stop) on the top (white) copy displayed at the worksite
to state that work has stopped. The PICWS takes the top (white) copy to
the Maintenance/ Engineering Authority for return to the Permit Control
Facility.
The original and the copy are now brought together by the Operations
Shift Co-ordinator and placed in a slot in the Suspended section of the
PCF display rack, with the white top (white) copy uppermost. This allows
Operations Department to gain an overview of Suspended Permits and
the following days commitments.
Box 13 Shift Handovers:
When a shift change occurs within an Engineering work period (e.g. 8
hour shifts) the work must stop until both the oncoming Asset Operator
and Area Authority have endorsed the Work Permit prior to endorsement
of the PICWS
Further Endorsements:
Where work has to continue on the following day the Asset Operator will
again check for conflict and approve the work continuation by initialing
Box 13. The top (white) copy is then issued at the Permit Control Facility
to the Maintenance/ Engineering Authority, who again takes it to the
worksite for endorsements as described above

space in Box 14b for the worksite.
The Asset Operator completes Box 14b, including the statements on
isolations.
Box 15a If the work is not completed, the PICWS will initial the space provided
in Box 15a and take the top copy to the Maintenance/ Engineering
Authority. The Maintenance/Engineering Authority takes the copy to
the PCF and completes Box 15a indicating the work status.
Box 15b If the Maintenance/ Engineering authority has indicated in Box 15a
that the worksite has been cleared the Area authority will confirm the
fact and sign Box 15b. The Asset Operator then completes Box 15b.
5.1.8 Archiving
After close-out, the Asset Operator is to file the original (white) copy of all
Permits, together with the top copies of any supporting Permits or Certificates,
as per archiving requirements (see Chapter 8).

5.2
COMPLETION OF THE GAS TEST CERTIFICATE
This Section should be read whilst referring to the Gas Test Certificate (See
Chapter 5, Figure 5.2).
If not specified by the Operations Co-ordinator at the Daily PTW meeting, the Shift
Controller should complete the Gas Test Certificate sections, relating to:
•
•
The Gas Testing Requirements;
•
The gas or gases to be tested for Worksite Certification.
The Test Frequency;
The results of the gas test will be entered on to the Gas Test Certificate which is
on the backside of the Work Permit, at the worksite, by the Authorised Gas Tester,
and (if the Area Operator is not undertaking the gas test) advise the Area Authority
of the result.
If the Area Authority is not undertaking the gas testing, then he must initial the
Certificate in the space provided to show he is aware of the test result(s).
For higher risk activities, such as Confined Space Entry and Hot Work-Category
1, the Issuing Authority is to witness the initial gas test prior to the issue of the
supporting Permit or Certificate.
Subsequent gas test results, as stipulated in the Test Frequency requirements
section, are to be recorded in the Additional Gas Test Record Section.
5.2.1 Archiving
After close out the Gas Test Certificate will be automatically archived with the
Work Permit

Any previous Hot Work Permit, Category 1, is to be entered
in the space provided.
Box 1a Identification of Task and its Location
The Originator will enter in Box 1a a description of the work for which
the Hot Work Permit is raised. It will be more specific than the
associated task description on the Work Permit and it will be the
description visible in the Permit display rack in the PCF.
The date that the Hot Work Permit is required is entered. This allows
planning of the preparatory work by Operations.

CHAPTER 5
Page 9 of 45
Box 4 Specific HSE Requirements
At the PTW Review Meeting the Maintenance/ Engineering Authority and
Operations Co-ordinator also agree the specific HSE equipment requirements
and tick the first column in Box 4a. Further, they will agree the PPE requirements
and tick the first column in Box 4b.
Box 5 Particular Hazards and Special Precautions
The Operations Issuing Authority completes Box 5, if any requirements are
identified over and above those already stated in Boxes 3 and 4.
The Issuing Authority must enter the category of PICWS presence. In Restricted
Areas, after agreement with the Asset Holder. The normal category of worksite
presence will be ‘A’ for Restricted Areas but in Unrestricted Areas will be
dependent on the risk.
The Hot Work Permit remains with Operations in the Permit Control Facility,
along with (but behind) its associated Work Permit, until it is ready for issue.
5.3.2 Permit Review and Issue
Box 6 In a Restricted Area, when the worksite preparations are complete, and the work
is ready to start, the Asset Holder will visit the workplace to personally confirm
that the requirements of Boxes 3, 4 and 5 are complete and initial the
appropriate spaces in Boxes 3 and 4. He will then sign Box 6.
If the Area is classified as Unrestricted then the Asset Operator for that area will
carry out the confirmation checks and sign Box 6.
If an interface activity is identified (see Chapter 3, Section 3.3.5) then a counter
signature is required from the Asset Operator of the other area.
For Pipelines only, because of the geographical practicality, the Asset Operator
may sign box 6 providing the Asset Holder has reviewed the Hot Work Permit
and authorized the Asset Operator to sign on his behalf

5.3.4 Endorsement for Continued Safety of the Worksite
Box 8
The Maintenance/ Engineering Authority will take the top (white) copy to
the worksite for endorsements in Box 8 by the Area Operator and
PICWS. The PICWS will display the Hot Work Permit at the worksite, on
top of the worksite copy of the Work Permit, in the plastic folder
provided for this purpose.
The 2nd (yellow) copy is retained in the Permit Control Facility and
visibly displayed in front of the associated copy of the Work Permit by
the Shift Controller.

CHAPTER 6
ACTIVITY SEQUENCE CONTROL FORM
6.1 OBJECTIVE
The Activity Sequence Control (ASC) form provides a useful tool in the PTW
System for work that involves several stages, or is complex, by allowing the work
to be described in a stepwise sequence, whereby:
•
the hazards are identified for each work activity
•
the controls to mitigate the associated risks are defined
•
the responsible parties at each stage are identified
The use of an ASC is recommended whenever a Work Permit covers more than
one work activity (see Chapter 3, Section 3.3.4), which requires clear identification
of boundaries of responsibility, e.g. more than one Trade discipline is involved.
6.2 Use of ASC in the Permit to Work System
The ASC is not intended to be a substitute for a Maintenance/ Engineering Method
Statement, but more a sequential listing of tasks so that hazard identification and
application of controls is structured. In particular, it provides a control mechanism
should any stage of the work require a signature of approval before proceeding to
the next stage.
An annotated version of the ASC, which provides guidelines for its completion, is
given in Figure 6.1.
A blank copy of the ASC Form is provided in Figure 6.2.
6.2.1 Responsibility for Identifying the Need for an ASC
The Activity Risk Assessment (ARA) team will normally be responsible for
identifying the need for, and the writing of an ASC (see Chapter 3, Section
3.4.2). An ASC will normally be presented with the Permit at the PTW
planning meeting for review and discussion, and is to be cross-referenced
in Box 4c of the Work Permit. Where incorporated, it is to be included in the
Toolbox Talks associated with the work.

CHAPTER 7
TOOLBOX TALKS
7.1 INTRODUCTION
This Section supports the Activity Risk Assessment Process described in Chapter 3,
Section 3.4 and should be read whilst referring to the Work Permit (Chapter 5,
Figure 5.1).
One of the last steps in the Activity Risk Assessment (ARA) Process is to discuss
the Work Permit, and any supporting Permits or Certificates, with the persons who
will actually be carrying out the work, and therefore be directly exposed to possible
release of hazards. This is achieved by holding a 'Toolbox Talk '.
Toolbox Talks are an essential element of safe working practices in GASCO’s sites
for both GASCO and contractor staff. The purpose of the talk is to discuss with the
working party:
• What the work activities will be;
• What hazards have been identified that will require controls during the course of
the work;
• What those controls are and how the work party will be affected.
The work party may, by virtue of their experience identify further hazards or may be
able to suggest alternative, or improved, controls. Where this is the case, the
hazards and additional precautions section of the Permit should, if necessary, be
modified and initialled after consultation and agreement with the validating and
issuing authorities.
The Originator of the Permit should formally capture this feedback by updating the
ARA, which can then be utilised the next time the work is undertaken.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 7
Page 2 of 7
7.1.1 Deciding on the need for a Toolbox Talk
The requirement for a Toolbox Talk will be decided by the Permit Originator,
based on his judgement of the risks involved and the work party’s experience
and familiarity with the task.
A formal Toolbox Talk is not normally required for routine jobs, covered by
maintenance procedures, which are carried out by competent staff and
which are undertaken frequently.
If the job is unusual, complex, is done infrequently, or, is being done by new
persons then a formal Toolbox Talk is required. The Toolbox Talk need not
cover all of the work at the same time. The Toolbox Talks may be given at
different stages of the job and should, where applicable, be linked to the Activity Sequence Control Form (ASC).
7.1.1.1 Checklist for identifying the need for a Toolbox Talk
To help the Originator decide if a formal Toolbox Talk is required
guidance is given in the matrix below
Work Aspect
Yes
No
Are there any Inexperienced (work experienced) Members
in the Work Party?
Is the Task unfamiliar to the Work Party?
Is the Work Site unfamiliar to the Work Party?
Is the Work Scope of a complex nature?
Is Multi-Trade Co-ordination required?
Is the Task HSE Critical?
Is the Task Operationally Critical?
Are hazards, or potential hazards, present?
Has there been any change to Work Scope?
Can Adverse Weather Conditions affect the Task?
Are Operations or Specialist Personnel to be
present?
If the answer to all questions is NO, a formal Tool Box talk is not required.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 7
Page 3 of 7
7.1.2 Format of the Toolbox Talk
Where there is a perceived higher risk, the Permit Originator should stipulate the
requirement for a formal record of the Toolbox Talk. In such cases, the Toolbox
Talk is to be recorded on the Toolbox Talk Record Form on the back of the PTW
The Toolbox Talk Record Form provides an effective communication means for
ensuring the work party are:
•
•
•
•
•
•
•
•
•
Aware of the work scope;
Aware of the hazards;
Knowledgeable as to the methods/ procedures to be adopted;
Aware of the PTW precautions/ controls;
Aware of any constraints;
Aware of what tools and equipment are to be used;
Aware of Environmental considerations;
Aware of any potentially conflicting activities;
Able to clarify any issues and provide comments.
Where included, the Toolbox Talk Record Form should be cross-referenced by
ticking the box in Section 4c of the Work Permit.

Rev 2.0 2009
CHAPTER 7
Page 4 of 7
7.1.3 The Presenter of the Toolbox Talk
The presenter of the Toolbox Talk(s) is to be agreed at the Daily PTW Meeting.
It is normally the person who knows most about the job. Depending on the
circumstances, it may be more than one person. For example, an Operations
person rather than an Engineering member of staff can better describe hazards
that may arise from Operations.
All members of the work party must indicate that they understand the Toolbox
Talk. Where different nationalities are involved, it may be necessary to appoint
an additional person who is conversant in that language, to assist the presenter
in the talk, in order to overcome any language barriers or literacy issues.
The Toolbox Talk should be repeated if:
(i).
The work party changes or new personnel are assigned to the work party;
(ii).
Circumstances, or conditions, relating to the work activity change;
(iii).
The work enters a different phase.

7.1.4 Checklist for the Toolbox Talk Presenter
After giving the Toolbox Talk, the Presenter should confirm the understanding of
the Work Party by using the following checklist as an aide-memoir:
Can all the personnel in the Work Group answer YES to the following questions?
Are all members of the work party aware of the hazards involved with the
work activity?
Are all members of the work party aware of the control measures required
to mitigate the risks associated with the hazards?
Are those people in the work party who are responsible for implementing
these control measures aware of their responsibilities?
Are these control measures in place?
Is everyone aware of what is being done at the worksite?
Is the work party aware of what everyone else is doing at the worksite?
Is there other work ongoing in close vicinity to the worksite, which the work
party need to be aware of?
Does the Person in Charge of the Worksite (PICWS) know an additional
Toolbox Talk is required should there be any significant change to the work
scope?
Does the PICWS understand the requirement to provide a Toolbox Talk to
any new people joining the work party?
Are there any Language/ Literacy Issues?
Does everyone know what to do in the event of a site alarm or
emergency?
If the answer to any of these questions is NO, then the safety of
people is at risk and must be addressed.

CHAPTER 8
PERMIT CONTROL FACILITY AND ADMINISTRATION OF THE PTW SYSTEM
8.1 OBJECTIVE
A fundamental requirement of any PTW System is that it provides a suitable
display of permitry on the facility, in a central location, to allow staff an overview of
current status. It is also required that all closed out permitry be archived in a
systematic fashion for easy reference and follow-up auditing purposes.
This section contains the detailed procedure for the handling of Work Permits,
supporting Permits and Certificates, and other related documents as they pass
between signatories and are administered through the Permit Control Facility
(PCF).
8.1.1 Permit Control Facility Requirements
8.1.1.1 Purpose of the Permit Control Facility
The Permit Control Facility (PCF) will be provided in a central point
of the Plant or Pipeline facility through which all Permits pass each
time their status changes, i.e. when Authorised, Endorsed,
Suspended or Closed.
This enables a check to be made that the work specified does not
conflict with any ongoing Permit work. It also allows a continuous
display of work in progress to be maintained.
It can, in addition, provide the venue for the daily Permit-to-Work
(PTW) meeting whereby all work requirements will be discussed
and agreed.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 2 of 10
8.1.1.2
Layout and Location of the PCF
The size and layout of the PCF will depend upon the complexity and
configuration of the facility. For a small and less complex facility it may be a
section of the Control Room, whilst for a more complex facility, if space
permits, it may merit a separate room.
The PCF should ideally be located in, or in close proximity to, the Control
Room or other central facility. Where this is impractical, the location should
be selected carefully to ensure that it is readily accessible to users, and will
not cause excessive additional journeys for personnel obtaining signatures.
A PCF has to be of sufficient size to house, in one location, all the
information displays boards, permit racks, and all the relevant files and data
that are required to be stored, for the Asset under the authority and control
of the Asset Operator. Where there is more than one Asset, with several
Asset Operators (e.g. Habshan), it is permissible to have separate PCF
facilities, providing the Shift Superintendent (the Asset Holder) can maintain
an overview.
Within the PCF, there should be physical separation between the occupants
and the customers so that only nominated personnel can alter the displayed
data.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 3 of 10
8.1.1.3 Facilities Within the PCF
Permit Rack: As a minimum, there are to be conventional racks for the display
of paper copies of all Permits from all departments on the Plant or Pipeline.
It is to be arranged in such a way that Permit location and status are readily
visible. This enables staff to readily check which equipment is under
maintenance and is not available for operation.
Permit Location Board: Ideally, there should be a plan of all areas and units
of the facility showing, as appropriate, the Hazardous Areas in correct
geographical orientation. The location of all Permit work in progress can be
indicated with suitable markers, together with safety system inhibits and the
position of barriers and scaffolding work.
Firemain and Fire & Gas System Schematic Diagrams: It is useful for
schematic diagrams of the Firemain and Fire & Gas System network to be
displayed in the PCF. These can be arranged in such a way that equipment for
maintenance or repair can be indicated in a highly visible manner. This
provides an indication of fire and safety systems not available for operation.
Desk and Counter Arrangement: This should be arranged to suit the
configuration of the PCF. It is recommended that it provide physical separation
between the customers and the Issuing Authority. This will allow the customers
visibility of the information displayed whilst ensuring that only authorised
personnel can alter the displayed data.
The Shift Controller, who is the Asset Operator responsible for shift operations,
will manage the PCF. The Assistant Shift Controller may assist him but there
must be clear understanding as to their individual roles and responsibilities,
when changing Permit status and updating displays, to avoid potential conflict
situations arising.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 4 of 10
8.1.2 PCF - Principles of Operation
In the PCF, for each asset under the control of the Asset Operator (Shift
Controller), all Permits and systems isolation boundaries will be systematically
displayed in one location, so that operators can readily see and check which
equipment is isolated for maintenance and not available for operation.
At the PCF, staff will be able to obtain key information to aid their decisions with
respect to Permits and the isolating and de-isolations of equipment. Data
displayed will cover the whole facility.
The facilities of the PCF are to be available throughout periods when work is in
progress on the Plant. When unattended, the PCF should be secured to
maintain the integrity of the information it contains.
8.1.3 Review and Control of Work under PTW
No work under a Permit is to be commenced until that Permit has been reviewed
by the Asset Operator (Shift Controller) to give confirmation that:
(1) The work does not clash with that being undertaken under the authority of
any other Permit or isolation.
(2) The Authorised Signatory is correct for the category of work and that the
Permit is correctly filled in.
No isolation or De-isolation is to be started until the appropriate
isolation/deisolation details are documented and agreed by the Shift Controller.
The Shift Controller should confirm that the proposed isolation boundary is
compatible with any other isolation boundaries in force under the PTW System.
Only when the above has been properly completed may the Permit be issued.
All Suspended and Closed Permits are to be displayed separately from those
Endorsed and Validated in the PCF Permit Display Racks.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 5 of 10
8.1.4
Segregation of Permits in Permit Display Racks
The Permit Control Facility (PCF) is to provide a Permit Rack system, suitable
for the display of permitry, sub-divided by Area of the Plant or Pipeline facility.
The Permit Rack arrangement should allow for the further segregation and
visual presentation of permitry status within the following sections (see also
diagrammatic representation, Figure 8.1):
VALIDATED Section
After validation, by the Maintenance/ Engineering Authority and the Asset
Operator (normally the Operations Co-ordinator), the Work Permit, together
with its additional supporting certificates are placed in the 'VALIDATED'
section of the Permit Display Rack.
Operations staff is now aware that planned work in the Operations area
has been approved but has not yet started.
The Shift Controller shall, prior to arranging for any worksite preparations,
check the Permit against other Permits displayed in the PCF for conflicting
activities. If any conflicts are identified, he is to advise the Originator and
Operations Co-ordinator who will agree either to:
a) Withdraw the new Work Permit, or,
b) Arrange for other Permits to be Suspended or Cancelled, dependent upon
relative priorities.
Once this step is completed the Shift Controller may authorise Worksite
preparations to proceed. He is to ensure that any other supporting documentation
(e.g. isolation/ blind lists) is retained in the Permit Rack along with the
associated permitry.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 6 of 10
8.1.4 Segregation of Permits in Permit Display Racks (cont.)
ENDORSED Section
When the worksite preparations and checks for conflict are complete, the permit
is issued by the Asset Operator (Shift Controller) and accepted by the
Maintenance/Engineering Authority who then takes the top, original (white) copy
to the worksite for Area Endorsement.
The 2nd (yellow) is transferred to the 'ENDORSED' section of the Permit
Display Rack
Operations staff is now aware that the planned work is actually proceeding
in the Operations Area.
At the start of each new shift period, prior to each subsequent endorsement of
the Work Permit, the Asset Operator will again check for conflict with any other
Work Permit or ongoing activity prior to releasing the Permit.
NB. It is permissible for the Assistant Shift Controller to carry out subsequent
endorsements of permitry on the agreement of the Shift Controller who is the
principle Asset Operator.
SUSPENDED Section
At the end of the Maintenance/ Engineering work period the original top copy, is
returned to the PCF and, together with the other copy, is transferred to the
'SUSPENDED' section of the Permit Display Rack. The permitry is to be
arranged with the top original (white) copy on top.
Operations staff are now aware that work which was in progress will/ has
been suspended but is to continue and isolations will/may be in place.
In the event of the Maintenance/Engineering Authority not returning permitry for
re-endorsement at the end of a shift period, the Asset Operator (Shift Controller
or Assistant Shift Controller) should change the display to SUSPENDED. As the
yellow copy will be displayed (instead of the white), it will be evident to the
incoming Asset Operator that action must be taken to follow-up with the
responsible Maintenance/Engineering Authority.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 7 of 10
CLOSED Section
When work has been completed, or a new permit is required, all the permitry
is transferred to the ‘CLOSED’ section of the Permit Display Rack.
Operations staff is now aware that the work is completed or requires
new permitry.
Prior to arranging for any de-isolations of equipment, the Shift Controller is to
check that de-isolations will not conflict with any other Work Permit or work
activity in progress.
NB. The permitry can be archived only once it is confirmed that all
de-isolations are complete.
8.1.5
PTW Administration and Document Control
8.1.5.1
Permit Return
The persons working under the PTW (the Accepting Authorities)
should have no direct access to Permit Display Racks. Only the Shift
Controller (or his nominated Assistant) may alter permit displays.
To provide a workable system for the return of completed, or
suspended, permits at the end of the working period, or on completion
of the job, it is recommended to provide a tray system in the PCF.
The tray system should have (as a minimum) two trays to accept the
return of all original permitry:
•
One for CLOSED - for completed and/or expired Permits out with
validity periods.
•
One for SUSPENDED - where work is to continue.
The Shift Controller (or his assistant) will then transfer them to, and
update, the Permit Display racks.
Closed permitry is to remain in the CLOSED section of the rack until
it is confirmed that the worksite conditions are as stated and, where
applicable, de-isolations have been completed and equipment
returned to normal status.
GASCO Permit to Work Standard
Rev 2.0 2009
CHAPTER 8
Page 8 of 10
8.1.5.2 Archiving of Permitry
All permitry is to be archived, by Area, in the PCF, or other adjoining facility,
which has a controlled access. The retention period for all permitry is 6 months
from the date of closure.
The recommended method of filing is to have a short term (monthly) archive
and long term (6-monthly) archive system. Closed out Permits are placed by
the dayshift Shift Controller into the short-term archive for later filing in the
long-term archive.
The long-term archive will have all Permits archived by month and area. Each
month the short-term archive contents will be transferred to the long-term
archive, replacing all permitry from the first month of the preceding 6-month
period. Such permitry removed from the Archive is to be destroyed.

sources:
(1) Proposals for Change.
(2) Audit Reports.
(3) Incident Reports.
(4) PTW training course feedback.
(5) Feedback from GASCO and Contractor Personnel.
All information from whatever source must be submitted in the form of a
Change Proposal (see 9.8) to enable it to be incorporated in the review
mechanism.
When the VP-HSE believes that sufficient changes to the PTW System
have been agreed to warrant it, he will request SVP (O) to authorise the
issue of an amendment to all controlled copies of the PTW System manuals.
9.5.3 Annual Review of Gasco PTW System
Proposals for changes to the PTW System Manual and/or procedures
therein should be submitted, in writing, by the respective Plant or Pipeline
Vice President, to the HSE custodian for initial review and approval. Any
subsequent amendments may then be authorised for issue by SVP (O),
if urgent, or, where not urgent, incorporated as part of the annual review
process.
There will be a formal annual review of the PTW System, and its operation,
led by the HSE Vice President. This review will encompass but will not
necessarily be limited to:
•
•
•
•
•
Incidents relating to PTW violations and non-compliances;
Level 1 and Level 2 Audit results;
The review of proposals for change to the PTW System;
All deviations applied for;
