What classification does flammable gas fall under in hazard classes?

The classification of flammable gas within the hazardous materials system is classified as Class 2. This category specifically identifies gases that can ignite easily and support combustion. Class 2 is subdivided into three divisions: Division 2.1 for flammable gases, Division 2.2 for non-flammable, non-toxic gases, and Division 2.3 for toxic gases.

Understanding this classification is crucial for emergency responders, as it helps to identify the required safety measures and response protocols when dealing with incidents involving flammable gases. This classification supports proper labeling, storage, and handling practices to mitigate risks associated with these materials.

Class 3 pertains primarily to flammable liquids, while Class 4 includes flammable solids and materials that may spontaneously ignite. Class 5 is associated with oxidizers and organic peroxides. Each of these classifications has different characteristics and safety requirements, further highlighting the importance of recognizing the correct hazard class for effective emergency management.
