Which pictogram is used to indicate a corrosive substance?

• A. Corrosive
• B. Explosive
• C. Flammable
• D. Environmental

Answer: (A)

The pictogram that signals a corrosive substance shows a liquid pouring from a container onto a hand and a surface, both being damaged. This icon communicates that the chemical can cause skin burns, eye damage, and can corrode metals. It’s distinct from the others: the explosive symbol indicates a hazard of explosion, the flame indicates flammability, and the environmental symbol shows harm to aquatic life and the environment. So the image with the hand and surface being damaged is the one used for corrosive materials.
