Which COSHH sign would indicate a toxic substance?

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

Answer: (A)

Reading hazard signs is what this item tests. The skull-and-crossbones pictogram is used to show acute toxicity—substances that can cause death or poisoning from a single exposure or short-term exposure at low doses. That is why it indicates a toxic substance. The other signs point to different hazards: a flame warns of flammability, a symbol for corrosion warns that contact can burn skin or corrode materials, and the harmful (exclamation) symbol signals a less severe hazard such as irritation or mild toxicity.
