What is a pesticide's "signal word" on the label used for?

The signal word on a pesticide label serves to designate the level of toxicity of that product. These words, which typically include "Caution," "Warning," and "Danger," provide critical information regarding the potential hazards associated with the pesticide.

For instance, "Caution" generally indicates that the product is slightly toxic, "Warning" suggests moderate toxicity, and "Danger" signifies a high level of toxicity that could be life-threatening. This system allows users, from trained applicators to homeowners, to quickly assess the safety risks when handling and applying the product.

Understanding this classification is vital for ensuring safe usage and minimizing the risk of harm to humans, animals, and the environment. The other options, while related to different aspects of pesticide labeling, do not pertain to the primary purpose of the signal word.
