What is classified under Class 1 of hazardous materials?

Class 1 hazardous materials are classified as explosives, which include substances and articles that can undergo a rapid chemical reaction resulting in the release of gas, heat, and possibly fragments. This classification focuses on materials that can create a significant risk of an explosion, which can be triggered by heat, shock, friction, or other external forces.

Understanding this classification is crucial for Hazmat Technicians, as it informs the appropriate handling, storage, and transport protocols necessary to mitigate risks. Proper identification and containment of explosives are essential to prevent accidents and ensure safety in environments where these materials are present.

The other classifications, such as flammable liquids, gases, and oxidizing substances, fall under different categories and do not share the explosive characteristics that define Class 1 materials.
