Question: 1 / 400

What does Toxicity Category 4 indicate?

Highly toxic

Moderately toxic

No signal word required

Toxicity Category 4 represents the lowest level of toxicity among the defined categories for pesticides and similar products. When a pesticide is classified as Toxicity Category 4, it indicates that the product poses a minimal risk to health when used according to the label instructions. As a result, no signal word—such as "Danger," "Warning," or "Caution"—is required on the label, which signals its relatively low toxicity. This is important for consumers and applicators, as it provides a clearer understanding of potential health risks associated with the product.

In contrast, higher toxicity categories carry specific signal words to alert users to the dangers presented by those products, emphasizing the need for caution and protective measures. For example, higher categories are associated with more significant health risks, impacting safety usage and handling protocols.
