Which signal word indicates the highest hazard on pesticide labels?

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

Answer: (B)

Signal words on pesticide labels communicate how toxic a product is and what level of precautions are needed. The order from lowest to highest hazard is caution, warning, danger, with danger-poison signaling the most severe risk. The phrase "Danger-Poison" indicates an extremely toxic product where even very small exposures can be fatal or cause serious harm, so it triggers the strictest safety measures, including enhanced PPE and restricted entry. The other terms convey high risk but not to the same extreme level.
