Corporate Safety – Procedure
Permit to Work
1.
Purpose
The Permit to Work (PTW) procedure defines the minimum requirements to provide a safe
system of Work when plant is taken from service for breakdown, maintenance or capital work
and when Work is not controlled as Pre-Approved Work at Seqwater operational sites. The
system also provides a trigger for the use of other permits for high risk work (2nd Tier
Permits) such as hot work, work at heights, confined spaces work, excavation, fault finding,
HV, and grid mesh, handrail and flooring removal.
This procedure is a documented system that provides a notification of intent and an approval
process, to undertake a specific scope of Work.
2.
Scope
The PTW process forms part of the Site Access and Works Control System (SAWCS) and
covers Seqwater employees, contractors and sub-contractor employees engaged in
operational, maintenance, inspection, construction, commissioning, decommissioning or
alteration activities, that are not controlled as Pre-Approved Work, carried out at Seqwater
owned and operated sites.
All principal contractors shall abide by this procedure or submit a Safety Management Plan
for endorsement by the Seqwater Workplace Health and Safety and Environment
Departments. Any submitted Safety Management Plan must, as a minimum, achieve the
intent of this procedure.
3.

Corporate Safety – Procedure
Permit to Work
TERM
DEFINITION
Isolations are discipline specific. Isolations and de-isolations must only
be performed within the Workers training, qualifications and competency
e.g.
Additional Isolator
Only licensed electricians may perform electrical isolations within an
electrical exclusion zone.
As a result, Permit Recipients will require additional resources to carry
out isolations when working with energy sources requiring multi
discipline isolations.
Additional Isolators work only under the direction of the Permit Recipient
or the Pre-Approved Worker.
Applicant
Person applying for access and or PTW from the Access Officer. The
Applicant may be requesting access on behalf of the Worker or
requesting access for themselves and their work party.
Break in work
Any time a Permit Recipient or Permit User of a PTW needs to leave a
job for any period of time other than for meal and ablution breaks.
CIS
Corporate Information System
De-isolation
The process of re-energising hazardous energy sources
Equipment Identification Tags are used to formally identify
equipment (in the field) and associate it to Pre-Approved Work or a
particular PTW.
Equipment
Identification Tag
Equipment Identification Tags are placed by the Pre-Approved
Worker or Permit Recipient prior to the commencement of any work
under the control of a PTW.
Equipment Identification Tags should be removed by the Worker-inCharge or Permit Recipient upon the completion of the task.
Equipment Identification Tags are green in colour.
An emergency is the sudden, unexpected, or impending situation that
may cause injury, loss of life, damage to property, and/or interference
with the normal activities of a worker or operations and which, therefore,
requires immediate attention and remedial action. e.g. fire, flood,
medical emergency.

Permit to Work Process
8.1 Application for a Permit to Work
Work is generally planned in advance allowing appropriate time for the management of plant
output to minimise disruption to services.
To begin the process the Permit Recipient or Applicant acting on their behalf sends the
request for Site Access and PTW via a MS Outlook Calendar Appointment addressed to the
appropriate Access Officer at least 48 hours in advance of the planned start date, where
possible by:
1. Searching the Access Officer Register (REG-00538) for the appropriate Access
Officer
2. Generating a MS Outlook Calendar Appointment addressed to the appropriate
Access Officer

The Appointment should contain the following information:
a. A description of the work (may include Work Order Number)
b. The location
c.
The time and duration for access
d. A message containing relevant information for the Access Officer to
approve your application, e.g. PTW.
Attach the required supporting documentation if available e.g. JSEA, Isolation
Instruction etc and send the outlook meeting request
If the Applicant/ Permit Recipient is unable to send an outlook meeting request they may use
the Access Officer Group telephone number to contact the relevant Access Officer. The
relevant information above must be provided verbally.
If there is no JSEA and or Isolation Instruction, one must be drafted on arrival to site before a
PTW Activation Number can be issued.
8.2 Call outs/ Breakdowns / Reactive Work
In the case where work is unscheduled (i.e. a breakdown/callout), the PTW process must still
be followed by the submission and review of a JSEA however:
1. The Access Officer may grant approval for access verbally via the call out and
record it in the Access Log at a later date
2. Review of the JSEA may be accepted by the signature of the Access Officer on
the JSEA and recorded in the Site Access Log at a later date
3. Approval and closure of the PTW may be granted by the signature of the Access
Officer on the PTW and recorded in the Access Log at a later date
8.3 Approval for Work
The Access Officer assesses the application by reviewing the JSEA and taking into account:
1. The type, priority and timing of the work.
2. Production and maintenance plans.
3. The items of plant and equipment that would require isolation and the impact this
would have on operations.
4. Confirm with the Supervisor the training and competency of those nominated to
conduct the work.
5. The impact of 2nd Tier Permits on operations.
The Access Officer notifies the applicant of acceptance or rejection of the application
Where a conflict with other works arises and or, there is a lack of information in the
application, the Access Officer may reject the Application.
Where a rejection occurs, the Access Officer identifies the issues with the Applicant and may
suggest an appropriate re-scheduling time.

Corporate Safety – Procedure
Permit to Work
The Access Officer shall:
1. If there are no sign in facilities i.e. remote site, the Access Officer must enter the
date and time of arrival in the Access Log.
2. Review the JSEA and Isolation Instruction with the Permit Recipient to:
Ensure the proposed Work does not produce conflicts in operational and
maintenance requirements for the site.
Identify area specific and process hazards that the Worker may not be
aware of (e.g. other workgroups in the area, chemical storage facilities,
changed conditions, etc).
Add any necessary controls to the JSEA.
3. Access to Work may be denied based on an inadequate JSEA, conflicting
priorities, and or a lack of information in the application.
4. Where a rejection occurs, identify the issues with the Permit Recipient. This may
include suggesting an appropriate re-scheduling time.
8.6 PTW Activation
When the Permit Recipient is ready to have the PTW activated they carry out the following
tasks:
1. Fill out the PTW
2. Review the JSEA with the work party
3. Fill out any 2nd Tier Permits as required
4. Confirm controls are in place for 2nd Tier permits if required
5. Attach the green Equipment Identification Tag to the equipment work is proposed
for, where appropriate
6. Contact the Access Officer to request a signature or a PTW Activation number.
A PTW can be activated by either the signature of the Access Officer or a PTW Activation
Number. The PTW Activation Number is generated from the Access Log. The Access
Officer must carry out the following tasks before activating the PTW:
1. Review the JSEA and check for work conflicts that impact or may be impacted
upon by the work proposed under the PTW.
2. Confirm controls are in place for 2nd Tier permits if required.
3. Confirm there is an isolation Instruction if required.
The Access Officer then signs the PTW or issues the PTW Activation Number and the Permit
Recipient records the number on the PTW to confirm the permit is activated.
If there are no Isolations required, the Permit Recipient locks their Personal Danger Lock and
Tag and Permit Recipient Tag onto the Permit Board.
8.7 Undertaking Isolations
Isolations are discipline specific. Isolations must only be performed within the Worker’s
discipline specific training, qualifications and competency. As a result, Permit Recipients will
require Additional Isolators when working with energy sources requiring multi discipline
isolations.
