Which signal word indicates moderate toxicity?

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

Answer: (B)

Label signal words tell you how toxic a pesticide is and what level of protection is needed. The word used for moderate toxicity sits between the high-toxicity and low-toxicity levels. Moderate toxicity is indicated by “Warning.” When you see this on a label, you should follow the precautions and wear the recommended protective gear to prevent exposure, but it’s not as severe as the “Danger” level.

High toxicity is shown by “Danger” or “Poison,” which calls for the strongest protections and most careful handling. Low toxicity is indicated by “Caution,” meaning a lesser level of precaution. “Advisory” is typically used for informational guidance rather than a hazard warning.
