What type of hazardous materials are classified as Class 1?

Class 1 hazardous materials are classified as explosives. This classification includes substances and items that can undergo a rapid chemical reaction, releasing gas and heat, which may lead to an explosion. Explosives are further divided into several divisions based on the nature of the explosive and the potential hazards they present.

Understanding this classification is essential for safety and regulatory compliance in transportation, storage, and handling of such materials, as they require specific precautions to prevent accidental detonation and to ensure safety during operations.

The other classifications mentioned—flammable solids, gases, and oxidizers—each have their own groups under different classes of hazardous materials but do not fall under Class 1, which is specifically reserved for explosives.
