6 Types of Permits
6.1
General
A written permit to work system provides formal written procedure and formal actions to
ensure that
potentially hazardous activities are carried out as safely as possible. The work permit is a
written document which authorizes persons to carry out the work concerned warns of possible
dangers and clearly states the precautions to be taken for the job to be carried out safely.
The permit ensures that full consideration is given to the hazards and risks, and that these are
properly dealt with, prior to commencement of the work.
The permit to work shall clearly specify the particular equipment and the construction area
involved, the extent of work allowed the conditions to be observed and the duration of the
permit. Whenever there is any doubt regarding the requirements for specific types of
permits, the HSE team should be consulted.
The instructions in the procedure are the minimum requirement and are mandatory.
Personnel must always comply with them and are not permitted to make arbitrary changes.
The present procedure considers the following permits:
• General Work Permit (cold)
• Hot Work Permit
• Confined Space Permit
• Electrical Work Permit
• Excavation Work Permit
6.2
Activities Requiring a Permit to Work
A Permit to Work will be required for the following activities:
• Any activity on live electrical equipment.
• Areas electrically classified.
• Closure of site roads to enable excavation and similar activities to be carried out.
• Confined space work (i.e., any work inside a manhole etc.).
• Connection to the electrical supply.

General Work Permit (cold)
The general Work Permit shall be utilized for all activities requiring a Permit to Work,
other than those capable of generating or using sources of ignition.
The general Work Permit will facilitate all activities from scaffold erection to
those controlling activities such as pressure testing.
The general Work Permit has the facility to be validated for a period of 07 consecutive
days.
Revalidation of any Permit to Work shall remain at the discretion of Construction
Manager and only if all Permit Signatories are in agreement, that there is no significant
change in condition, changes in work schedule or there is no significant changes in
personnel.
Permits to Work shall clearly specify the particular equipment and the construction
area involved the extent of work allowed the conditions to be observed and the
duration of the permit.
6.4
Hot Work Permit
The Hot Work Permit shall be utilized for all activities requiring a Permit to Work, capable of
generating or
using sources of ignition. Some examples include:
• Electrical welding and use of welding machine,
• Flame cutting,
• Grinding (producing sparks)
6.5
Confined Space Permit
A confined space entry permit is required to allow personnel to enter a confined space such as a
blade, trench, tank, vessel, etc.
When hot work, cold work, electrical work, and/or energy isolation work is carried out in a
confined space, an additional permit(s) (as required by the type of work) must be applied.
Entry into confined spaces is subject to special requirements being put into place prior to the
commencement of work. This will include but not be limited to:
• Condition monitoring
• Presence of a Safety Watch Person
• PPE/RPE
• Emergency Escape Plan
P a g e 10 | 23
6.6
Electrical Permit
An electrical permit is required for work on electrical systems
where there is a possibility of contacting energized electrical conductors. Some
examples include:
• Work involving the installation or repair of electrical conductors,
• Connection or disconnection of electric motors,
• Reaching into any panel, transformer or other electrical enclosure which may have
energized circuits, capacitors, wiring, etc.
6.6.1 Lock out-tag out
De-energization (Isolation) may be required prior to installation, inspection, repair, cleaning or
dismantling. Where a job involves isolation of equipment, there shall be a work permit for the job
and a lockout and tag-out procedure shall be followed:
A lockout generally involves:
• Stopping all energy flows (for example, by tuning off switches or valves on supply
lines).
• Locking switches and valves.
• Securing the machine, device or power transmission line in de-energizer state.
Electrical isolation may be required to immobilize machinery or to protect personnel working
in electrical equipment. Situations involving electrical isolation including rotating machinery
and machinery with moving parts and entry into vessel which contain stirrers or agitators.
Electrical isolation should be performed only by a competent electrical engineer.
Energization may be required for executing pre-commissioning electrical test. Where a job
involves temporary energization, there should always be a work permit for the job and a
power on and power off procedure should be followed.
• The padlock has to be provided with a tag reporting:
• ID number as recorded in the isolation logbook.
• Date and time of lock out.
• Name and signature of the individual who installed the padlock and the reason of the
installation.
• Warning tags has to be properly secured with wire to the isolation points to ensure the
same does not fall off.
An example of a Warning Tag and Tag-out and lock-out are shown in Figure 3.
P a g e 11 | 23
Figure 3. Example Warning Tag and Tag-out/Lock-out tags.
If the equipment is provided with an electrical isolation facility available on the field (e.g.
start/stop button or other switchgear) then the Competent Electrical Engineer should attempt
electrical start test in the field. This is to ensure that the equipment is no longer live and to
verify that the electrical isolation is effective. The Competent Electrical Engineer then, shall
fit a second numbered padlock, together with a “Danger: Do Not Operate” tag, to the local
electrical isolation point.
In situation where it is not possible to lockout or chain off an isolating device, isolation may be
accomplished by removal of fuses, disconnection of electrical cables or physical removal of a
component of the system supplying energy to the equipment. The point of physical interruption
shall be identified with a dedicated tag.
If other organizations or individuals working on equipment shall also install their locks and
tags at locations have to be fit. In that case multiply lockout clips (Hasps) shall be used if
necessary. When all padlocks will be removed energization will be possible. An example of
Hasps is shown in Figure 4.
Figure 4. Example HASP
P a g e 12 | 23
The Competent Electrical Engineer shall report all actions on the substation logbook for record
purpose. As a general rule other discipline engineers cannot interfere with any electrical
isolation work to be executed inside the substation for safety reasons and nobody (with the only
exception of the Competent Electrical Engineer) can take or keep the padlock keys for their
scopes.
Field HSE Supervisor should hold spare keys for all Lock Outs. This ensures no keys will go
missing.
6.6.2 Execution of Energization, Removal of Tags, Padlock and Restoration of Power
The case where ENERGIZATION is required, the Competent Electrical Engineer shall proceed
to energize the equipment. The following procedure covers the energization for safe execution of
the pre-commissioning electrical tests.
• If a padlock and a tag are installed (to show that the switchgear is isolated) the Competent
Electrical Engineer shall remove both of them.
• The Competent Electrical Engineer will give power to the equipment.
• As soon as the equipment is energized the Component Electrical Engineer shall
hung a tag “IN SERVICE” close to the switchgear, as shown in Figure 5.
The Competent Electrical Engineer shall report all actions on the substation logbook for record
purpose.
Figure 5. Example of “In Service” tag.
6.7
Excavation Permit
An Excavation permit is required for any excavation or ground disturbance activity that
involves digging, trenching, excavating, or removing soil or ground.
P a g e 13 | 23
A designated spotter will be added to the permit when mechanical equipment is being used
to excavate or disturb the ground such as trenchers, backhoes, excavators, etc. This will ensure
adequate observation is being conducted to prevent hitting underground utilities and to
detect any unusual objects or sounds.
6.8
Permit issuance and duration
The Permit to Work will involve the following steps shown below:
1. Conduct a thorough risk assessment and determine who is at risk, what control measures are
necessary to eliminate the hazards, and the level of residual risk.
2. Prepare a written system of work identifying the following:
•
List Isolation / Pre-work precautions
•
List prohibited activities (communicate to others as necessary)
•
List Plant and Equipment required
•
List Personnel Protective Equipment to be used
•
List sequence of events as planned with identified hazards/residual risks and controls
clearly defined
•
Emergency procedures for all foreseeable risks (ensure that procedures are conveyed to
competent persons and fully understood)
3. Discuss the hazards and controls necessary to prevent them from occurring with those who
will be required to operate under the Permit to Work (for example during Toolbox Talks and
STARRT card).
4. Ensure that those conducting the task know that the safe system must be followed in full, and
that no other methods or sequence of work are allowed (i.e., work must stop, all persons
withdrawn, and the safe system reviewed by the Authorized Person). If the safe system is found
to be flawed, then the Permit must be cancelled, the system of work reassessed, a new Permit
raised, and those conducting the task re-briefed.
5. Ensure that the permit is displayed at the work site, to provide information to all those who
need to know.
6. Ensure that the work area is clean, tidy, and that all safety devices have been replaced and are
functioning correctly, prior to inspection by the Authorized Person.
The Permit to Work can be invalidated under any of the following conditions:
•
•
•
The conditions on the permit are not complied with.
Area or unit conditions change, e.g., venting or spillages of hazardous materials occurred,
etc.
Any time an emergency or alarm raises at the site, ALL PERMITS ARE
SUSPENDED. This confirms that personnel are disengaged from the work and that all
P a g e 14 | 23
work activities cease during an emergency or perceived emergency.
