WORK PERMIT SYSTEM
1.0 INTRODUCTION
The Work Permit System is an important
tool for safety in hydrocarbon processing /handling. The recommended Work Permit
System is described covering various
aspects like when a work permit is required,
types of permits, responsibilities, check
lists, validity etc. The success of a Work
Permit System depends upon the training,
motivation and participation of all
individuals concerned with itsimplementation. Since several maintenance/
construction jobs are often carried out withassistance from contractors, it is essential to
provide sufficient exposure to contractor
and his employees as well.
If the work has to be performed in a
hydrocarbon processing/ handlinginstallation by any person other than the
operating personnel of that area, a duly
authorised written permit shall be obtained
by the person/agency executing the work
before commencement of the work.
However, even for operating personnel,
when work has to be performed outside
their normal routine, an exclusive permit to
that effect by the authorised person shall be
obtained.
2.0 SCOPE
The Work Permit System shall cover all
hydrocarbon processing / handling
installations such as onshore /offshore
processing platforms, gas treating units,
crude oil terminals, refineries, pipelines,marketing installations and LPG bottling
plants.
3.0 DEFINITIONS
a) Hot Work : Hot Work is an activity which
may produce enough heat to ignite a
flammable air - hydrocarbon mixture or aflammable substance.
b) Cold Work : Cold Work is an activity which
does not produce sufficient heat to ignite a
flammable air- hydrocarbon mixture or a
flammable substance.
4.0 TYPE OF WORK PERMITS
Based on the nature, the work shall beundertaken either under Hot Work Permit
or Cold Work Permit, for which formats are
exhibited in pages 17-38. Explanatory notes
to check-list items of the formats are
provided under Section 7.0.
The two types of permits, one for cold work
and the other for hot work are the minimum
requirements which must be fulfilled before
commencing work. For jobs like
excavation, road/dyke cutting, electrical
lockout / energising etc., where the work
permit issuing authority may have to take
clearances from other sections/ personnel,
organisations may introduce supplementary
formats for these purposes, if they considerit necessary. Format for electrical lockout/
energising is given in OISD-STD-137 on
"Inspection of Electrical Equipment".
Radiography must be carried out when
occupancy is least. For precautions to be
taken during radiography, refer OISD-STD-
155 on "Personal Protective Equipment".
In addition to the regular work permit,
supplementary permits as required by thelocal statutory bodies are also to be issued.
5.0 PROCEDURE FOR WORK PERMIT
SYSTEM
Following is the procedure for theimplementation of Work Permit System :
2
-
7/28/2019 20468421 Work Permit System
3/30
(a) The Work Permit System shall always operate
on "Owner - In-charge" concept. (Example:
Process Unit-Shift In-charge; Laboratory-
Chief Chemist; Depot-Depot Manager;
Pipelines Installation- Shift In-charge). Theconcerned management shall issue the
appropriate authority limits for variousinstallations and type of permits based on
this concept.
(b) The permit shall be in printed form.
(c) Separate forms shall be used for Hot Workand Cold Work.
(d) A system of colour coding is recommended to
identify two types of permits. The
recommended colours are pink for Hot
Work Permit and yellow for Cold Work
Permit. All permits shall be serially
numbered.
(e) Hot Work Permit shall be in four copies. Theoriginal shall be in pink colour and other
copies shall have the word "COPY" printed
in large pink letters.
Cold Work Permit shall be in two copies. The
Original shall be in yellow colour and the
copy shall have the word "COPY" printed
in large yellow letters.
(f) It is recommended that both Hot Work Permit
as well as Cold Work Permit be made in theform of books with tear-off facility. In the
case of Hot Work Permit, the authorised
Original copy shall be given to the receiver,
the Duplicate to the Fire Section, Triplicate
to Safety Section and Quadruplicateretained in the book. In case of Cold Work
Permit, the authorised Original shall be
issued to the receiver, retaining the
Duplicate in the book.
It is recommended that plot plans of the
installation and the operating blocks should
be displayed in the Fire and concerned UnitControl Rooms respectively and site of hot
jobs under progress should be indicated onthese plot plans with red pins. This helps
the incoming supervisor /s (both in Fire and
Operating Departments) to get a quick idea
of the hot jobs being undertaken and help in
identifying the areas which require
inspection / attention, depending upon the
criticality of the area and the job.
The Safety Officer/Fire Officer / Officer
authorised will make periodic check of the
Hot Work Sites and see that the work is
being carried out as per conditions laiddown in the Hot Work Permit. At any point
of time, if he considers that the conditionsare not safe enough for the work, he may
suspend the work and inform the Work
Permit Issuing Authority to restore the safe
conditions so that work can be restarted.
(g) For simplification of procedure, Hot WorkPermit also covers permission for vessel
entry, vessel boxing-up and excavation. All
activities outside the scope of Hot Work
Permit shall be covered by Cold Work
Permit.
(h) No hot/cold work shall be undertaken without
a work permit except in the areas pre-determined and designated by the owner-in-
charge. All work permits shall be issued bythe person who is designated as responsible
person for the operation of the area where
work is to be carried out. In respect of work
permits for handling highly critical types of
work and also for long duration work such
as in construction jobs in a running
installation, the authorising level should be
elevated.
(i) The work may be planned to be done either
departmentally or through a contractor. Ineither case, the work permit should be
received and signed by the maintenance /
project /construction supervisor of the
company as he is responsible for the work
of the contractor also. Where no suchindependent
supervisor exists, for example in small
installations, the owner-in-charge can issue
the permit to the contractor's supervisor
directly and obtain his signature.
(j) Permit should be issued only for a single shift
and its validity should expire at thetermination of the shift. However, where
the work has to be continued, the samepermit may be revalidated in the succeeding
shift, by authorised person after satisfying
the normal checks.
In instances like plant turn around or an
activity where work is of continuous nature
involving round the clock activity, blanket

(vi) Running water hose/Portable extinguisher
provided
Running water hose and portable fire
extinguisher are required respectively toflush / dilute in case of release of any
hazardous chemical or to quench sparks andto put out small fires immediately.
(vii) Fire water system checked for readiness
In order to meet any contingency, it should
be ensured that the fire water systemincluding fire water pumps, storage,
network etc. is checked and kept ready for
immediate use.
(viii) Equipment blinded / dis-connected / closed
/ isolated / wedge opened
Equipment / Vessel, on which the workpermit is being issued, should be
completely isolated from the rest of theplant with which it is connected during
normal operation, in order to ensure that
there is no change in the work environment
with respect to presence of toxic /
flammable gases, liquids, hazardous
chemicals etc. in the course of the work.
Blinding is one of the most effective waysof isolation. Blinds should be installed as
close to the vessel as possible. If lines
cannot be blinded, they should bedisconnected and the open ends should be
made safe by installing pipe caps/plugs,
blind flanges, mud packing etc.
(ix) Equipment properly drained /
depressurised
Equipment under pressure should be
depressurised after isolation.This will be
followed by draining / purging / water
flushing etc. as the case may be.
Equipment containing liquid hydrocarbonsshould be drained completely. There may
be a possibility of overlooking liquidcollected in pockets or inaccessible areas
such as level gauges, small nozzles /
bleeders on vessels, laterals in pipework
etc. All low point drains should be in
unplugged condition.
(x) Equipment properly steamed / purged
Purging of equipment (vessels, pipelines,
compressors etc.) is done to make them free
of flammable hydrocarbons and toxic gases.
Steam / Inert Gas is used for gas-freeing ofvessels and pipes in refineries and other
locations. Other means of purging is bydisplacement with water and final traces of
gas removed by air eductor. All high point
vents should be unplugged while purging.
Purging may be done continuously or in
batches to conserve purge medium. It
should be done in a systematic manner tocover the entire equipment/plant and
continued till the concentration of toxic /
flammable gas is lowered to allowable
level.
(xi) Equipment water flushed
Water flushing is an effective means ofcooling, cleaning and even gas-freeing of
equipment. It is also employed to removetraces of acids / chemicals. Equipment
metallurgy must be considered before using
sea / saline water. Sometimes, flushing with
demineralised water would be necessary
depending upon the metallurgy of the
equipment.
(xii) Gas / Oxygen deficiency test done and
found OK
Gas test includes measurement of :
(a) Hydrocarbons by Explosimeter
(b) Oxygen Deficiency by Oxygen Meter
(c) Use of Calibrated Meters
(d) Toxic gases like Hydrogen Sulphide,
Carbon Monoxide, Nickel Carbonyl,
Chlorine etc. by techniques like Indicator
Tube method, Lead Acetate Paper etc.
Measurement of lead in air is required forentering leaded tanks and personal
protective equipment shall be worn beforeentering the tank. Octel/Ethyl regulations
are to be followed while handling leaded
gasoline tanks.
Gas tests may be specified for vessel entry
including open excavation where head of a
man will be below ground level and when

(xxii) Precaution against public traffic taken
In case hot work is to be carried out in
close proximity of a public road, for
example in the case of a trunk pipeline, itmay be desirable to block-off/divert public
traffic for the duration of the job as aprecautionary measure.
(xxiii) Clearance obtained for excavation from
Technical/ concerned departments
For any excavation work which may affectunderground sewers / telephone lines /
cables / pipelines etc., Technical Services
Dept. and / or other concerned departments,
should be consulted for obtaining the co-
ordinates and the depth to which excavation
can be resorted to, without damaging the
existing facilities. Markers should be put
around the area where excavation can bedone and the depth can be indicated in the
work permit.
(xxiv) Clearance obtained for road cutting from
Technical / Fire / concerned
departments
Since road cutting can hamper the
movement of the fire vehicles, initial
clearance should be obtained from FireDepartment and final approval from the
higher designated authorities. If the road is
wide, preferably the road should be cut halfat a time. Duration of road cut should be
restricted as far as possible.
(xxv) Clearance obtained for dyke cutting
When the dyke is cut, any mishap in the
tank farm can lead to a free flow of oil to
outside the bund. A high level authority
should be designated for authorising dyke
cutting. Further, it should be ensured that
dyke would be reconstructed in the shortest
possible time. For example, if pipes have to
be laid through the dykes, the pipes shouldbe laid quickly and plugged / capped so that
the dyke can be closed. Thereafter, balanceof pipe fabrication can continue without any
risk. Standby personnel should be available
at the work site, who should possess a
suitable size steel plate for blocking the
opening in case of mishap/tank failure. If no
work is undertaken in evening and night
shifts, invariably the gap should be closed
with steel plate and mud packing at the endof day's work.
(xxvi) Checked Flame / Spark arrestor on
mobile equipment
No vehicle / engine without flame / spark
arrestor is permitted in operating areas.
(xxvii) Checked for oil / gas trapped behind
lining in equipment
Before undertaking hot jobs, a check should
be done for oil / gas trapped behind lining
in the equipment. Many a times oil / gas
trapped behind lining depicts itself in the
form of swelling and can be confirmed byway of drilling holes.
(xxviii) Welding machine checked for safe
location
Welding machine should be located in a non-
hazardous and ventilated area. It should
have proper supervision while welding job
is in progress. It should be switched off
immediately on completion of the job.
(xxix) Checked for earthing/return connection to
the equipment being welded
Before commencing the welding job, ensure
that all the cables and earthing connections
are as per the standard welding codes /
practices.
(xxx) Oxygen and Acetylene cylinders kept
outside the vessel / tank
While performing welding / cutting jobs in
confined spaces like vessel / tank, ensure that
oxygen and acetylene cylinders are kept
outside and hoses for the gases are in goodworking condition, without any cracks or
wrinkles. Also, hoses should be tightlysecured at both the ends i.e. the torch and the
cylinder.
