DOT hazard class 2 corresponds to:

DOT hazard class 2 corresponds to:

• A. Explosives
• B. Gases
• C. Flammable solids
• D. Corrosives

Answer: (B)

The main idea here is recognizing which DOT hazard class is assigned to gases. DOT class 2 is designated for gases, including flammable gases, non-flammable non-toxic gases, and toxic gases (which are categorized further as 2.1, 2.2, and 2.3). Gases are typically stored under pressure, may be compressed, liquefied, or dissolved, and can pose hazards such as pressure-related release, flammability, and toxicity depending on the specific gas. That’s why gases fit this class. Explosives belong to a different class, explosives, which is Class 1. Flammable solids are Class 4, and corrosives are Class 8.
