Which signal word indicates the highest hazard on a pesticide label?

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

Answer: (C)

Signal words on a pesticide label show how hazardous the product is and what level of protection is needed. Danger is used for the most serious hazards, such as highly toxic or severely corrosive products, and it tells you that strict precautions are necessary to prevent serious harm. This often means using special protective equipment and handling practices to keep people, pets, and the environment safe. Warning indicates a moderate hazard, while Caution and Advisory point to lower levels of risk. So, the signal word that indicates the highest hazard is Danger.
