LP-gas (propane, butane or mixture) is, in many cases, an indispensable fuel for industrial space heating.
When use of portable containers is necessary and their location outside of buildings or structures is impracticable, containers and equipment may be used inside in accordance with the provisions of NFPA Pamphlet 58 as are applicable to the particular use or occupancy. The common sense rules in this bulletin should be applied for the safe use of LP-gas in such instances.
Space heating refers to the heat for personnel or other requirements and usually means infra-red heaters, salamanders or standard space heaters.
Locate containers, regulators, piping and hose where they will not be subjected to damage, tampering or excessive temperature. Container valves should be protected from physical damage while in use either by being recessed or by a suitable protective collar. Containers, in use, must be upright and on a firm foundation or secured.
Do not drop containers.
Temporary space heating units must be designed for use with LP-gas and should be listed by a
nationally recognized testing laboratory such as American Gas Association, Underwriters’
Laboratories, Canadian Gas Association and/or be acceptable to the authority having jurisdiction.
Heaters shall be located at least 6 ft. from any LP-gas container. This shall not prohibit the use of heaters specifically designed for attachment to the container or to a supporting standard, providing they are designed and installed so as to prevent direct or radiant heat application from the heater onto the container. Blower and radiant type heaters shall not be directed toward any LP-gas container within 20 ft.
