What type of materials must be stored in designated locked locations according to fire safety regulations?

Storing hazardous materials in designated locked locations is crucial for maintaining safety at construction sites. Fire safety regulations specifically require that any substances classified as hazardous—such as flammable liquids, toxic chemicals, and reactive materials—be secured to prevent unauthorized access, minimize the risk of accidents, and protect workers and the public from potential harm.

Designated locked locations help ensure that these dangerous substances are handled properly and only accessed by trained personnel, reducing the likelihood of spills, fires, or other emergencies. This regulation is part of a broader effort to promote workplace safety, as improper storage of hazardous materials can lead to severe health risks and environmental damage.

In contrast, materials such as construction paper, personal protective equipment, and wooden pallets do not typically pose the same level of risk and therefore do not require the same stringent storage protocols.
