What does the signal word 'Danger' indicate?

• A. Highly toxic.
• B. Moderate toxicity.
• C. Low toxicity.
• D. Not toxic.

Answer: (A)

Signal words on labels tell you how severe the hazard is. When you see "Danger," it signals a high level of risk—often indicating something is highly toxic or capable of causing serious harm with even short exposure. That’s why it’s the strongest warning word used for toxicity and other severe hazards, so you should take the strictest precautions and follow all label directions exactly. The other end of the spectrum uses milder wording for less severe hazards, so they don’t indicate the same level of risk as Danger.
