Which statement about hazard signal words is true?

• A. Caution indicates high toxicity
• B. Danger indicates low toxicity
• C. Danger indicates high toxicity
• D. Warning indicates high toxicity

Answer: (C)

Hazard signal words communicate how severe a hazard is. Under the standard labeling system, the word used for the most serious hazards is Danger, while Warning is used for less severe hazards. Caution isn’t a standard signaling term for high-toxicity hazards on these labels. Therefore, Danger indicates high toxicity because it flags the highest level of hazard and often accompanies statements like “Fatal if swallowed” or “Highly toxic,” signaling you must handle the substance with maximum care. The other statements don’t fit the established signaling system: Danger does not indicate low toxicity, and Warning does not indicate the highest level of hazard.
