Organizations using flammable and combustible liquids should have a designated storage area. In facilities where significant amounts of flammable and combustible liquids are stored, a flammable liquid storage cabinet provides added protection to keep employees and property safer from fires.
Flammable liquid storage cabinets serve a number of purposes:
Flammable liquid storage cabinets are only effective if they can withstand the high temperatures common to flammable liquid fires. Employers may fabricate their own flammable liquid storage cabinets or purchase them from a commercial supplier or local dealer.
Whether purchased from a dealer or fabricated in-house, all cabinets should conform to OSHA standard 1910.106(d)(3), “Design, construction and capacity of storage cabinets”. All flammable liquid storage cabinets purchased from a manufacturer should be listed or approved by a nationally recognized testing laboratory.
Flammable liquid storage cabinets do not require ventilation. If ventilation is desired, the ventilation openings should be:
Cabinet doors should remain closed when not in use. Although many cabinets are equipped with a fusible link designed to shut the doors during a fire, the best practice is to keep the doors closed and properly latched at all times.
Cabinets must be conspicuously labeled to indicate that the cabinet contains flammables or combustibles. A label, such as “Flammable — Keep Fire Away” should be displayed on the cabinet doors to inform employees to keep open flames and sources of ignition away.
According to the NFPA®, a maximum quantity of 60 gallons of flammable liquids or 120 gallons of combustible liquids may be stored in a single flammable liquid storage cabinet. Additional cabinets should be purchased if storage requirements exceed the recommended amounts.
