Which class in the HAZMAT classification includes gases?

The classification of hazardous materials (HAZMAT) is crucial for ensuring safety in various environments, especially in emergency situations. Class 2 specifically pertains to gases, which can be further divided into several categories, such as flammable gases, non-flammable gases, and toxic gases. This classification is essential for identifying the potential risks associated with these materials, as gases can pose unique challenges in terms of containment, transportation, and exposure.

Understanding this classification helps emergency responders prepare and respond effectively to incidents involving gases, ensuring that proper precautions and protective measures are taken. In contrast, the other classes mentioned focus on different types of hazardous materials that do not include gases; Class 1 deals with explosives, Class 4 focuses on solids, and Class 5 pertains to oxidizers. By recognizing Class 2 as the category that includes gases, responders can appropriately address the specific hazards associated with gaseous substances.
