What is the signal word for a label with skull and crossbones?

• A. Caution
• B. Warning
• C. Advisory
• D. Danger

Answer: (D)

Signal words convey how dangerous a pesticide is, and the skull and crossbones pictogram is the classic symbol for poison, indicating the highest level of acute toxicity. When this symbol is present, the label uses the strongest warning word: Danger. It cues you to take very strict precautions and wear appropriate protective gear. Caution would be for minor hazards, Warning for moderate hazards, and Advisory isn’t used with this pictogram. So, the correct signal word is Danger.
