What is the primary difference between Class 1 and Class 2 hazardous materials?

The primary difference between Class 1 and Class 2 hazardous materials lies in their definitions and the types of hazards they present. Class 1 materials, also known as explosives, include substances that can cause a rapid release of gas and heat when subjected to certain conditions. This class encompasses items such as dynamite, fireworks, and other explosive devices, which are highly regulated due to the potential for causing significant damage and injury.

On the other hand, Class 2 materials refer to gases, which can be compressed or liquefied and can include flammable gases, non-flammable gases, and toxic gases. Examples include propane, acetylene, and chlorine. These gases can pose risks through flammability, asphyxiation, or toxicity when they are released into the environment.

Thus, the distinction clearly places Class 1 as focusing on explosive materials, while Class 2 encompasses a variety of gases with different properties and hazards. Understanding this classification is vital for safety in handling, transporting, and responding to incidents involving these substances.
