Which of the following is classified as a HAZMAT class 1?

The classification of hazardous materials under the HAZMAT system is divided into several classes based on the nature of the hazards they present. HAZMAT class 1 specifically refers to explosives. This classification includes materials that may cause explosive reactions under specific conditions, such as heat, shock, or friction. Explosives are further divided into subclasses based on their properties and the manner in which they present their hazards.

Understanding this classification is important for responders, as it influences the safety measures taken during transport, storage, and emergency response scenarios. Classifying materials accurately helps in preventing accidents and ensuring appropriate precautions are taken to manage risk associated with these dangerous substances.
