What is the main difference between a "Class 1" and a "Class 2" hazardous material?

The distinction between Class 1 and Class 2 hazardous materials is rooted in the specific classifications established by the U.S. Department of Transportation. Class 1 materials are classified as explosives, which includes a wide variety of substances that may detonate or cause a rapid reaction, potentially leading to dangerous situations, particularly in a fire or impact scenario. This classification is crucial as it requires specialized handling, storage, and transport protocols to mitigate the risks associated with their explosive nature.

On the other hand, Class 2 materials encompass gases, which can be further categorized into flammable gases, non-flammable gases, and toxic gases. The nature of gases as a form of matter presents unique hazards, including the risk of explosion, as well as health risks from exposure or inhalation.

Understanding the specific nature and risks associated with these classes allows for adequate safety measures to be implemented when dealing with hazardous materials, ensuring the protection of emergency responders and the public.
