Hazardous Materials Class 2 covers which type of material?

• A. Explosives
• B. Gases
• C. Oxidizers
• D. Radioactive

Answer: (B)

Gases are the focus of this class. Class 2 covers all gases, whether compressed, liquefied, or dissolved under pressure, including flammable gases (like propane), nonflammable non-toxic gases (like nitrogen), and toxic gases (like chlorine). The classification helps with packaging, labeling, and handling because gases can expand, leak, or ignite, so they require pressure-rated containers and specific safety measures. Explosives belong to a different class that deals with energetic materials capable of detonation, oxidizers are in their own class (oxidizing substances that can intensify combustion), and radioactive materials are classified separately due to radiological hazards.
