What is the maximum amount of Category 4 flammable liquid that can be stored in a cabinet?

The maximum amount of Category 4 flammable liquid that can be stored in a cabinet is 120 gallons. This aligns with the guidelines set by the National Fire Protection Association (NFPA) and Occupational Safety and Health Administration (OSHA), which categorize flammable liquids based on their flash point and define safe storage practices to minimize fire hazards.

Category 4 flammable liquids are those with flash points of greater than 200 degrees Fahrenheit, which are considered less hazardous compared to those with lower flash points. The limit of 120 gallons in a storage cabinet is established to prevent excess quantities of flammable materials in a single area, thereby reducing the risk of fire or explosion and ensuring easier management in case of emergencies. This quantity allows for safe storage while also considering accessibility for use and adherence to safety regulations.

The other amounts listed exceed the safe limit for a single cabinet, which is designed to contain potential hazards and prevent larger-scale incidents.
