How many gallons of Category 1, 2, or 3 flammable liquid can be stored in a cabinet?

The correct answer is based on the National Fire Protection Association (NFPA) standards and the Occupational Safety and Health Administration (OSHA) regulations regarding the storage of flammable liquids. A storage cabinet for flammable liquids is designed to provide a safe environment for their storage and protect them from external hazards.

For Category 1, 2, or 3 flammable liquids, the maximum capacity allowed in a single storage cabinet is 60 gallons. This limit is established to minimize the risk of fire and ensure that if an incident occurs, it is contained within the cabinet, reducing the potential for widespread damage and exposure. The storage cabinet is required to be designed to withstand fire for a certain period to protect its contents.

The other choices suggest amounts above this limit, which do not comply with safety regulations that prioritize the handling and storage of flammable materials to prevent accidents and safeguard employees. Thus, the maximum specified amount of 60 gallons in a cabinet aligns with safety best practices and regulations.
