What types of items should never be placed in a flammable liquid storage cabinet?

A flammable liquid storage cabinet is specifically designed to store flammable liquids safely, minimizing the risk of fire hazards in the workplace. The correct choice highlights that items like cardboard, paper, and combustible painting supplies should never be placed in such cabinets because they are all considered combustible materials. These items can ignite easily and contribute to the spread of fire, compromising the safety measures the cabinet is meant to provide.

By keeping flammable liquids away from combustible materials, the risk of an accident or fire is greatly reduced. Fire safety regulations generally prohibit the storage of combustible items in these cabinets to ensure that if a fire does occur, it does not have readily available fuel to spread rapidly.

Other options, like fire extinguishers and safety goggles, are actually essential in maintaining safety protocols and should be accessible in areas where flammable materials are stored. Non-toxic cleaning agents and water are usually considered safe for storage in such spaces, provided they do not possess flammable characteristics. Electronic devices and batteries may also pose some risk but are not as directly related to the purpose of the flammable storage cabinet as combustible supplies.
