What does the signal word Danger indicate?

• A. Moderate toxicity
• B. Low hazard
• C. High toxicity
• D. Unknown risk

Answer: (C)

High hazard level is signaled by the word Danger on chemical labels. It tells you that exposure can cause severe health effects or serious injury, so you must take extreme precautions and use appropriate protective measures every time you handle or work with the substance. This is why the correct choice is high toxicity—the Danger label indicates a high level of hazard.

Moderate toxicity or low hazard would be shown with less severe words, and unknown risk isn’t conveyed by Danger, which signals a known, significant hazard. When you see Danger, treat it as a cue to maximize safety: minimize exposure, use proper PPE, and follow strict handling and emergency procedures.
