Which hazard class is corrosives categorized under, and give an example.

• A. Class 7; example: radioactive material.
• B. Class 8; example: sulfuric acid.
• C. Class 3; example: acetone.
• D. Class 1; example: explosives.

Answer: (B)

Corrosives are classified as the hazard class that covers materials capable of causing chemical burns to skin and tissue and can also corrode metals. This focus on corrosive injury and material damage is why sulfuric acid, a strong acid that can severely burn and corrode, is a classic example. Recognizing that corrosives cause rapid tissue and metal damage helps explain the strict handling, PPE, and containment precautions used with them. Other hazard classes include radioactive materials, which involve radiation risks; flammable liquids like acetone, which burn readily; and explosives, which pose detonation hazards.
