8.2.2 Flammable Storage Cabinets
The requirements for the use of flammable storage cabinets are determined by the classification of the flammable liquids, the quantities kept on hand, the building construction (fire wall ratings), and the floor of the building the flammables are being stored on.
For stand-alone flammable cabinets (as opposed to cabinets underneath fume hoods), there are vent holes on each side of the cabinet (called bung holes) that must have the metal bungs screwed into place for the cabinet to maintain its fire rating. Venting of flammable cabinets is NOT required, however, if a flammable cabinet is vented, the cabinet must be vented properly according to the manufacturer’s specifications and NFPA 30.
Typically, proper flammable cabinet ventilation requires that air be supplied to the cabinet and the air be taken away via non-combustible pipes. If you plan to vent your flammable storage cabinet, please contact EHS at 607-255-8200 or askEHS@cornell.edu for more information.
