Which pictogram is used to indicate corrosion hazard to skin and metals?

• A. Corrosive
• B. Exclamation mark
• C. Environment
• D. Health hazard

Answer: (A)

This pictogram signals a corrosion hazard. It indicates that the chemical can cause skin burns and eye damage and may be corrosive to metals. You’ll typically see imagery suggesting a substance attacking a hand and a metal surface, which communicates both personal injury risk and material damage.

Because of this, it’s a cue to use protective gloves, goggles or a face shield, and protective clothing, and to handle and store the chemical away from metals and incompatible materials. The other pictograms have different meanings: the exclamation mark covers milder hazards like irritation or eye irritation; the environment pictogram warns about harm to aquatic life; and the health hazard pictogram covers more serious long-term health effects such as carcinogenicity or respiratory hazards.
