Which hazmat class is divided into three divisions for flammable gas, non-flammable gas, and poisonous gas?

• A. Class Two - Gases
• B. Class Three - Flammable Liquids
• C. Class Five Oxidizing Substances and Organic Peroxides
• D. Class Four - Flammable Solids

Answer: (A)

Hazmat classification uses classes and, for gases, divisions to capture different gas hazards. Class 2 is specifically for Gases, and it is divided into three divisions: flammable gases, non-flammable (non-toxic) gases, and toxic (poisonous) gases. The question lists those three types—flammable gas, non-flammable gas, and poisonous gas—so the category that fits is Class Two – Gases. The other options describe different material states or hazard types (flammable liquids, flammable solids, or oxidizers/organic peroxides), which don’t match the gas-focused divisions described here.
