Not more than ___ gallons of flammable liquid shall be stored in any one approved storage cabinet.

• A. 5
• B. 3
• C. 60
• D. 120

Answer: (C)

Storing flammable liquids in an approved cabinet is limited by the cabinet’s listed fire-load rating. The maximum amount allowed in one cabinet designed for flammable liquids is sixty gallons. Keeping to this limit ensures the cabinet’s listing remains valid and the heat and vapors are contained within its design, giving responders and occupants a safer scenario if a spill or ignition occurs. If you need to store more, you’d use additional cabinets or a different approved storage area. The larger figure typically cited—one hundred twenty gallons—applies to combustible liquids in a cabinet, not flammable liquids, which is why that option isn’t correct here.
