Why are special requirements needed for flammable liquid storage rooms in industrial operations?

by Nils Deacon, Manager, Inspections and Rating Services

Industrial operations use fuel, paints, and other agents that have very low flash points which can ignite at low temperatures when exposed to an ignition source. The ignition sources can vary from static electricity to open flame heating units.

NFPA 30, The Flammable and Combustible Liquids Code, and NFPA 30A address the need for proper storage of flammable liquids in these settings.

Flammable liquid storage rooms must have 8’’ masonry walls with concrete floors. A raised 4’’ sill or ramp and a self closing 1-½ hour rated fire door complete the enclosure. Electric lighting and fixtures must be installed with Class 1 Hazardous rating. To vent flammable vapors, mechanical exhaust with explosion proof motors is required.
