Which symbol corresponds to Corrosive?

• A. Radioactive
• B. Oxidizing
• C. Corrosive
• D. Explosive

Answer: (C)

Understanding hazard pictograms and what corrosive means in safety labeling. The corrosive symbol is the one that shows a liquid being poured onto a hand and a metal surface, both of which are being damaged. This specifically communicates that the substance can cause chemical burns to skin and damage or corrode metals, so it demands protective gear and careful handling to prevent contact. The other common pictograms represent different hazards: a trefoil for radioactive materials, a flame over a circle for oxidizing agents that can fuel or intensify fires, and an exploding bomb for materials that may detonate. Since corrosives are defined by their ability to chemically burn skin and corrode materials, the hand-and-metal damage pictogram correctly conveys that warning.
