Which hazard class is represented by the placard illustration labelled 'Corrosives'?

• A. Dangerous when wet
• B. Radioactives
• C. Poison gases
• D. Corrosives

Answer: (D)

Seeing a placard labeled Corrosives points to substances that can cause severe damage to skin and eyes and can corrode metals. This identifies the corrosives hazard class (Class 8). The placard symbol typically shows a liquid contacting a hand and a metal surface, illustrating the corrosive effect. Because the label explicitly names corrosives, it directly matches this class rather than other hazard categories. The other options correspond to different classes—dangerous when wet, radioactive, and toxic gases—each with its own distinct placards and meanings, so they don’t fit the label shown.
