In the DOT hazard class system, which class has oxidation as its primary hazard?

• A. Class 3 Flammable Liquids
• B. Class 2 Gases
• C. Class 5 Oxidizers
• D. Class 8 Corrosives

Answer: (C)

Oxidizers have oxidation as their primary hazard. In the DOT hazard class system, materials that promote or sustain combustion by releasing oxygen are placed in Class 5. Their defining danger is oxidation, meaning they can cause or intensify fires rather than being primarily flammable themselves. Examples include ammonium nitrate, potassium permanganate, and concentrated hydrogen peroxide. The other classes focus on different hazards: flammable liquids ignite easily, gases pose risks related to their gaseous state, and corrosives cause material and tissue damage through chemical corrosion. So, the class dedicated to oxidation is oxidizers.
