DOT Hazard Class 5 consists of which type?

DOT Hazard Class 5 consists of which type?

• A. Flammable liquids
• B. Flammable solids
• C. Oxidizers
• D. Poisons

Answer: (C)

Class 5 is about oxidizing substances. These materials release oxygen or contain oxygen-rich compounds that can help other fuels burn more fiercely, sometimes even igniting on contact with heat or friction. They’re not primarily about being flammable liquids or flammable solids, and they’re not poisons. That’s why oxidizers are the correct focus for this class, and organic peroxides are included as a reactive subgroup within it. Examples of oxidizers you might encounter include ammonium nitrate or potassium nitrate, which can promote combustion of nearby materials, unlike plain flammable liquids or toxic substances.
