Which signal word indicates the highest toxicity level for pesticides?

The signal word "Danger" indicates the highest toxicity level for pesticides. In the context of pesticide labeling, signal words are crucial for understanding the potential hazards associated with the chemical. "Danger" is used when a pesticide poses a high toxicity risk and could cause severe harm or even death if proper precautions are not followed. This signal word alerts users to the critical nature of the product, emphasizing the need for strict adherence to safety guidelines during handling and application.

Other signal words, such as "Warning" and "Caution," represent lower levels of toxicity. "Warning" indicates a moderate toxicity level, while "Caution" signifies a lower hazard risk. The term "Alert" is not a standard signal word used to describe pesticide toxicity, adding to the clarity of "Danger" as the most severe indicator of risk. Understanding these distinctions is essential for safely managing and applying pesticides.
