What is classified as class four hazards?

Class four hazards are specifically associated with flammable solids. This classification pertains to materials that can ignite easily and may cause fires through friction, absorption of moisture, or spontaneous combustion. The properties of flammable solids necessitate careful handling and storage to avoid incidents that could lead to fires.

Oxidizing substances, which are meant to enhance combustion, are classified under different regulations. Explosives, due to their ability to create sudden and violent reactions, fall within another hazard class focused specifically on such reactions. Corrosive materials are classified as those that can cause destruction of living tissue or severe corrosion of material, indicating a very different type of hazard than that of flammable solids.

Understanding these classifications is crucial for emergency response teams to properly identify and manage hazardous materials during incidents.
