Which signal word indicates the lowest toxicity?

Which signal word indicates the lowest toxicity?

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

Answer: (C)

Pesticide labels use signal words to show how toxic a product is and what precautions to take. Among the common signal words, Danger signals the highest toxicity and requires the strongest precautions, Warning indicates a moderate hazard, and Caution indicates the lowest level of acute toxicity. Therefore, the word that best represents the lowest toxicity is Caution. It means the product is less hazardous than those labeled Danger or Warning, so the precautions associated with it are correspondingly less stringent.
