Which signal word indicates a product is highly toxic by any route of exposure and can cause death in very small doses?

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

Answer: (A)

Signal words on pesticide labels indicate how acutely toxic a product is and how strict the precautions must be. The strongest warning is “Danger-Poison,” which means the product is extremely toxic by any route of exposure and can cause death in very small doses. Because of this level of hazard, the label demands maximum safety measures—appropriate personal protective equipment, careful handling to avoid skin or inhalation contact, and secure storage and placement away from children and animals. In comparison, “Danger” alone signals a high hazard but is not necessarily tied to death from any route; “Warning” denotes a moderate hazard, and “Caution” indicates relatively low hazard. So recognizing the exact phrase “Danger-Poison” tells you to treat the product with the utmost care and follow all labeling instructions precisely.
