DEFINITIONS AND ABBREVIATIONS
a)
Hot Work: An activity that can produce a spark or flame or other source of ignition having sufficient energy to cause ignition, where the potential for flammable vapors, gases, or dust exists. This includes all works, which produces spark, running of IC engine, breaking of concrete, use of ordinary torches, use of battery operated devices etc.
b)
Cold Work: Cold Work is an activity that does not produce sufficient heat to ignite a flammable air- hydrocarbon mixture or a flammable substance.
c)
Radiation Work : Any activity that is carried with a source of ionizing radiation, which does not produce sufficient heat to ignite a flammable air- hydrocarbon mixture or a flammable substance.
d)
Working at Height : Any activity that is carried out at 2.0 meters & above on temporary structure, scaffolds or on a structure not meant to do particular job safely.
e)
Excavation : Any job, which requires excavation / digging of earth. An Excavation is any man-made cut, cavity, trench, or depression in an earth surface that is formed by earth removal. A Trench is a narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth of a trench is greater than its width, and the width (measured at the bottom) is not greater than 15 ft (4.6 m). If a form or other structure installed or constructed in an excavation reduces the distance between the form and the side of the excavation to 15 ft (4.6 m) or less (measured at the bottom of the excavation), the excavation is also considered to be a trench.
f)
Confined Space : It is an enclosure with known potential hazards and restricted means of entrance and exit. It is not meant for normal occupancy of people and is usually not well ventilated such as vessels, boilers, storage tanks, large diameter piping etc. The excavation more than 1.2 M deep, entry into floating roof tanks, when roof is more than
ISMS Standard-1006
Page 7 of 34
3M down from the top, space located below ground level such as pits, drain channels etc shall also be considered as confined space. g)
Lower Explosive Limit (LEL): LEL is the minimum concentration of a vapour in air (or other oxidant) below which propagation of flame does not occur on contact with an ignition source. This is usually expressed as volume percentage of the vapor in air.
h)
Upper Explosive Limit (UEL): UEL is the maximum concentration of a vapor in air (or other oxidant) above which propagation of flame does not occur on contact with and ignition source. This is usually expressed as a volume percentage of vapors in air.
i)
Pyrophoric Substance : Substances that ignites spontaneously in air at ambient temperature. In hydrocarbon industries iron sulphide is the most commonly observed pyrophoric substance and is called as pyrophoric iron.
ij
Self Contained Breathing Apparatus (SCBA): It is an life saving personal protective apparatus consisting of a face mask, combined with a hose and source of fresh air generally in form of a cylinder of compressed air, to be carried by bearer.
k)
Gas Safety Inspector (GSI)/Issuer: GSI means a designated officer authorized to perform all necessary tests before signing a work permit. He must satisfy himself by a personal inspection that the tank / vessel /line /equipment/ any other confined space involved is safe for the work intended. He can independently issue Cold work permit and permit for working at height.
l)
Fire Permit Signatory (FPS)/Issuer: FPS means a designated officer authorized to issue work permit. He is ‘Fire Permit Signatory’/‘Issuer’ in case of Hot work/ Vessel entry/ Excavation permit and for any other permit. He issues the permit for the particular job after addressing the checklist points of permit for the units/ areas, where he is the incharge. FPS will sign the permit after getting satisfied that GSI has carried out all the tests/checks and signed the permit.
m)
Receiver (Permittee) : The ‘Receiver’ the designated person authorized to receive work permit. Receiver generally is the executing department officer, who has to execute the particular job for which permit has been issued. The executing officer can be Engineer In-charge / Site in-charge of the job or any other nominated officer for executing dept. (normally service dept).
n)
Blanket permit : The hot work permit issued to areas after due consideration to safety (the fire hazard is minimum and hazards due to adjoining facilities taken into consideration) with approval of local management for a maximum period of 1 month. Such permit shall not need shift-wise renewal, however the executer has to ensure that permit conditions are complied throughout the work period.

Page 26 of 34
d. Surrounding area checked / cleaned: Unsafe conditions for performance of work may arise from surrounding area. It should be cleaned-up to remove flammable material such as oil, rags, grass etc. e. Sewers, Manholes, Closed Blow Down (CBD) etc. and Hot Surfaces covered: Flammable gases may be released from nearby sewers. Hot un-insulated surfaces (equipment / pipelines) may provide a source of ignition and therefore, these are to be properly covered to prevent fires. f. Hazard from other routine / non-routine operations considered and persons alerted: Other activities (routine / non-routine) being carried out near-by, which can create conditions unsafe for performance of the permit work, should be taken into consideration and the concerned persons should be alerted accordingly. g. Equipment electrically isolated and tagged: Before issuing a permit, it shall be ensured that electrical isolation has been done, switches are locked-out and cautionary tags duly signed with date and time are attached. h. Running water hose / Portable extinguisher provided / Fire water system available: Running water hose and portable fire extinguisher are required to flush / dilute in case of release of any hazardous chemical or to quench sparks and to put out small fires immediately. In order to meet any contingency, it should be ensured that the fire water system including firewater pumps, storage, network etc. is checked and kept ready for immediate use. i.
Equipment blinded / disconnected / closed / isolated / wedge opened: Equipment for which the work permit is being issued, should be isolated from the rest of the plant 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 ways of isolation. Blinds should be installed as close to the equipment as possible. If lines cannot be blinded, these should be disconnected and the open ends should be made safe by installing pipe caps / plugs, blind flanges etc.
j.
Equipment properly drained / depressurised: Equipment under pressure should be depressurised after isolation. This should be followed by draining / purging / water flushing etc. as the case may be.
k. Equipment containing liquid hydrocarbons should be drained completely. There may be a possibility of overlooking of liquid collected in pockets or inaccessible areas such as level gauges, small nozzles / bleeders on vessels, laterals in pipe work etc. All low point drains should be in unplugged condition. l.
Equipment properly steamed / purged: Purging of equipment (tanks, vessels, pipelines etc.) is done to make them free of flammable hydrocarbon and toxic gases. Steam / Inert Gas is used for gas freeing of vessels and pipes in refineries and other locations. Other means of purging is by displacement with water and final traces of gas removed by properly earthed air eductor. All high point vents should be unplugged while purging. It
ISMS Standard-1006
Page 27 of 34
should be done in a systematic manner to cover the entire equipment / plant and continued till the concentration of toxic / flammable gas is lowered to allowable level. m. Equipment water flushed: Water flushing is an effective means of cooling, cleaning and even gas freeing of equipment. It is also employed to remove traces 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. n. Gas / Oxygen deficiency test done: Gas test includes measurement of: • • •
•
Hydrocarbons by Explosive meter. Oxygen Deficiency by Oxygen Meter. Toxic gases like Hydrogen Sulphide, Carbon Monoxide, Sulphur dioxide by multi-gas meter. Nickel Carbonyl, and Chlorine etc. by techniques like Indicator Tube method, Lead Acetate Paper Paper etc. For details of gas testing refer standard on “Confined Space Entry”.
