Which class is assigned to Corrosive materials?

• A. Class 7
• B. Class 3
• C. Class 2
• D. Class 8

Answer: (D)

Hazardous materials are grouped by the type of danger they pose, and corrosive substances are placed in the corrosives class. These materials can cause severe chemical burns to skin and eyes and can corrode metals, so they’re treated as a distinct danger with specific handling and packaging requirements. The category includes acids and alkalis, like sulfuric acid, hydrochloric acid, and sodium hydroxide, which is why they’re grouped together.

This helps explain why corrosive materials belong to the corrosives class rather than the other classes. Gases have their own class, flammable liquids have their own class, and radioactive materials have their own class. So the correct association is the corrosives class.
