Show answer & explanationAnswer & explanation
Correct answer: B. Ability to cause severe damage to living tissue or corrode materials.
Class 8 materials are defined as corrosive substances. Their primary hazard is their ability to cause severe damage to living tissue (skin, eyes, respiratory tract) upon contact or to corrode metals and other materials.
Why the other options are wrong
- A. Radiation is associated with Class 7 (Radioactive Materials).
- C. Explosion is primarily associated with Class 1 (Explosives).
- D. Flammability is associated with Class 3 (Flammable Liquids) or other flammable classes, not Class 8.
Class 8: Corrosive Materials
Class 8 hazardous materials are corrosive substances that, by chemical action, will cause severe damage when in contact with living tissue or, in the case of leakage, will materially damage or destroy other freight or the transport vehicle.
- Primary hazard: tissue damage and material corrosion.
- Includes acids, bases, and other corrosive chemicals.
- Requires protective measures for handling and transport.
Memory trick: Eight is Great for Dates, but for Corrosives, It's Destructive Traits!
