What is the purpose of the signal word on a pesticide label?

The signal word on a pesticide label serves a vital purpose by indicating the acute toxicity level of the product. This classification helps users understand the potential danger associated with the pesticide's use. Signal words are standardized terms derived from the pesticide's toxicity data, providing quick insight into how hazardous the product might be.

For example, a label may use signal words such as "Caution," "Warning," or "Danger," with "Danger" indicating a high level of toxicity, and "Caution" suggesting a lower level. This system is crucial because it informs handlers and users about the level of care and protective measures they need to take when using the product, ensuring safety for both people and the environment. Understanding this information is essential for the responsible application of pesticides and for compliance with safety regulations.
