Which Hazard Class Covers Corrosive Substances?

• A. Class 2 Hazards
• B. Class 5 Hazards
• C. Class 8 Hazards
• D. Class 7 Hazards

Answer: (C)

Corrosive hazards are categorized by their ability to chemically burn tissue and corrode materials, so they belong to a class dedicated to caustic substances. This Class 8 designation covers acids, bases, and other materials that cause severe damage on contact with skin or eyes and can damage metals. That’s why corrosives are placed here rather than in other hazard classes. For comparison, Class 2 covers gases, which pose pressure or asphyxiation risks; Class 5 includes oxidizers and organic peroxides that can intensify fires; Class 7 covers radioactive materials with radiation hazards. So the correct classification for corrosives is the class focused on caustic substances. When handling them in the field, expect splash hazards and the need for chemical-resistant PPE and proper decontamination procedures.
