Which COSHH sign would indicate a corrosive substance?

• A. Corrosive symbol
• B. Flammable symbol
• C. Toxic symbol
• D. Harmful symbol

Answer: (A)

The main idea is recognizing the hazard pictogram used for corrosive substances. The corrosive sign shows a hand and a metal surface being attacked by a liquid, which directly communicates that the chemical can cause severe skin burns, eye damage, and can corrode metals. That direct message is what makes it the indicator for corrosive hazards. Other signs point to different dangers—one warns of flammability, another of poisoning or acute toxicity, and another of general harmful effects. They don’t convey the specific risk of corrosion, so they aren’t the correct symbol when the hazard is corrosive.
