Multiple Choice

Hazard class 2.2 is associated with which type of materials?

Gases fall under hazard class two, and division two point two specifically covers non-flammable, non-toxic gases. That’s why non-flammable compressed gases are the correct type. These gases don’t burn and don’t release toxic vapors under normal conditions, but they can pose risks like asphyxiation if they displace air or create high-pressure hazards when released. The other options don’t fit because flammable gases belong to a different division (2.1), toxic liquids aren’t gases (toxic gases fall under 2.3), and corrosive solids aren’t gases (they’re assigned to other classes/ divisions).
