Which type of signal word indicates that a pesticide is moderately toxic?

The choice indicating that a pesticide is moderately toxic is associated with the signal word "WARNING." In pesticide labeling, signal words are essential for conveying the level of toxicity of the product to users, including applicators and consumers.

The signal word "WARNING" is specifically used to indicate that the product poses a moderate risk if it is ingested, inhaled, or absorbed through the skin. It serves as a caution to users that while the pesticide is not as highly toxic as those labeled "DANGER-POISON," it still requires careful handling and appropriate safety measures.

Understanding these signal words is crucial for safe pesticide use and handling; they guide users in recognizing the potential health risks. By knowing that "WARNING" indicates moderate toxicity, users can make informed decisions about personal protective equipment and safety practices when using the product.

The other options include "DANGER-POISON," which denotes a high level of toxicity, "CAUTION," indicating low toxicity, and "SAFE," which does not correspond to any accepted toxicity classification in pesticide labeling. Therefore, the signal word "WARNING" clearly marks the product as moderately toxic.
