Which set of signal words could be required on a pesticide label?

• A. Notice; Alert; Caution
• B. Caution; Warning; Danger
• C. Safe; Hazard; Danger
• D. Warning; Caution; Hazard

Answer: (B)

Signal words on pesticide labels convey hazard level and the precautions you should take. The standard words used to indicate increasing risk are Danger, Warning, and Caution. A product with the highest acute toxicity might use Danger, a less hazardous one Warning, and a still lower hazard level Caution. The set that includes Caution, Warning, and Danger uses exactly these official signal words in the correct terminology, so it could appear on a pesticide label.

Other options mix terms not used as hazard signal words on labels, such as Notice, Alert, Safe, or Hazard. Since these aren’t the recognized signal words for communicating hazard levels, they wouldn’t be the correct set to appear on a pesticide label.
