Which signal word indicates a product is moderately toxic either orally, dermally, or through inhalation, or causes moderate eye and skin irritation?

• A. Danger-Poison
• B. Danger
• C. Warning
• D. Caution

Answer: (C)

Signal words on pesticide labels show how toxic a product is in acute exposure. When a product is moderately toxic by mouth, skin, or inhalation, or it causes moderate eye or skin irritation, the label uses the word that sits in the middle of the hazard scale: Warning. This level indicates a middle-range hazard, higher than what would be labeled Caution but not as severe as Danger or Danger-Poison. So the correct choice communicates that moderate risk clearly to users, guiding them to take appropriate precautions. The other terms correspond to higher or lower hazards: Danger means very high toxicity or severe effects, while Caution signals only minor hazards. Always follow the label’s directions and wear the recommended PPE.
