HIGHLY FLAMMABLE LIQUIDS AND FLAMMABLE COMPRESSED GASES:
1. Application-These rules will be applicable to all factories where highly flammable liquid or
flammable compressed gases are manufactured, stored, handled or used.
2. Definitions-For the purposes of this Schedule-
(a) "flammable compressed gas" means flammable compressed gas as defined in Section
2 of the Static and Mobile Pressure Vessels (Unfired) and Rules, 1981 framed under the
Explosives Act , 1984; and
(b) "highly flammable liquid" means any liquid including its solution, emulsion or
suspension which when tested in a manner specified by Sections 14 and 15 of the
Petroleum Act, 1934 (Act No. 30 of 1934), gives off flammable vapours at temperature
less than 32 degrees centigrade.
3. Storage-(1) Every flammable liquid or flammable compressed gas used in every factory shall be
stored in a suitable fixed storage tank, or in a suitable closed vessel located in a safe position under the
ground, in the open or in a store room of adequate fire resistant construction.
(2) Except as necessary for use, operation or maintenance, every vessel or tank which contains or
had contained a highly flammable liquid or flammable compressed gas shall be always kept closed and all
reasonably practicable steps shall be taken to contain or immediately drain off to a suitable container any
spill or leak that may occur.
(3) Every container, vessel, tank, cylinder, or store room used for storing highly flammable liquid
or flammable compressed gas shall be clearly and in bold letters marked "Danger-Highly Flammable
Liquid" or "Danger- Flammable Compressed Gas".
4. Enclosed systems for conveying highly Flammable Liquids-Wherever it is reasonably
practicable, highly flammable liquids shall be conveyed within a factory in totally enclosed systems
consisting of pipelines, pumps and similar appliances from the storage tank or vessel to the point of use.
Such enclosed systems shall be so designed, installed, operated and maintained as to avoid leakage or the
risk of spilling.
5. Preventing formation of Flammable Mixture with Air-Wherever there is a possibility for leakage
or spill of highly flammable liquid or flammable compressed gas from an equipment, pipeline, valve, joint
or other part of a system, all practicable measures shall be taken to contain, drain-off or dilute such spills or
leakage as to prevent formation of flammable mixture with air.
6.Prevention of Ignition-
(1) In every room, workplace or other location where highly flammable liquid or flammable
compressed gas is stored, conveyed, handled or used or where there is danger of fire or explosion from
accumulation of highly flammable liquid or flammable compressed gas in air, all practicable measures
shall be taken to exclude the sources of ignition. Such precautions shall include the following-
(a) all electrical apparatus shall either be excluded from the area of risk or they shall be of such
construction and so installed and maintained as to prevent the danger of their being a
source of ignition;
(b) effective measures shall be adopted for prevention of accumulation of static charges to a
dangerous extent;
(c) no person shall wear or be allowed to wear any footwear having iron or steel nails or any
other exposed ferrous material which is likely to cause sparks by friction;
(d) smoking, lighting or carrying of matches, lighters or smoking material shall be prohibited;
(e) transmission belts with iron fasteners shall not be used; and
(f) all other precautions, as are reasonably practicable shall be taken to prevent initiation of
ignition from all other possible sources such as open flames, all frictional sparks,
overheated surface of machinery or plant, chemical or physical-chemical reaction and
radiant heat.
7. Prohibition of smoking-No person shall smoke in any place where highly flammable liquid or
flammable compressed gas is present in circumstances that smoking would give rise to a risk of fire. The
occupier shall take all practicable measures to ensure compliance with this requirement including display of
a bold notice indicating prohibition of smoking, at every place where this requirement applies.
8.Fire Fighting- In every factory where highly flammable liquid or flammable compressed gas is
manufactured, stored, handled or used, appropriate and adequate means of fighting a fire shall be provided.
The adequacy and suitability of such means which expression includes the fixed and portable fire
extinguishing systems, extinguishing material, procedures and the process of fire-fighting, shall be to the
standards and levels prescribed by the Indian Standards applicable, and in any case not inferior to the
stipulation clause 31 of section 18(2)(f) and rude made thereunder.
9.Exemptions-If in respect of any factory, the Chief Inspector-cum-Facilitator is satisfied that
owing the exceptional circumstances of infrequency of the processes or for any other reason, all or any of
the provisions of this Schedule is not necessary for protection of the workers in the factory, the Chief
Inspector-cum-Facilitator may by a certificate in writing, which he may at his discretion revoke at any time,
exempt such factory from all or any of such provisions subject to such conditions, if any, as he may specify
therein.
