Which signal word indicates the highest acute toxicity?

Which signal word indicates the highest acute toxicity?

• A. Danger
• B. Warning
• C. Caution
• D. None

Answer: (A)

Signal words on pesticide labels convey how severe the hazard is from acute exposure. The word that indicates the highest acute toxicity is Danger. It signals a serious health risk and is used when a product can cause severe harm quickly, often requiring immediate precautions. This is why it’s the best answer. Warning and Caution indicate progressively lower levels of acute hazard, so they’re used for less dangerous substances. None isn’t correct because there is a distinct label for the most severe acute hazard.
