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

The purpose of the signal word on a pesticide label is to indicate the product's relative acute toxicity to humans and animals. This critical information helps users quickly assess the potential danger associated with the pesticide formulation. Signal words such as "Caution," "Warning," and "Danger" are standardized indicators that reflect the level of hazard, guiding users in their decisions regarding handling and applying the product safely. The presence of this word directs attention to the precautions that must be taken to avoid harmful exposure, facilitating informed choices about which pesticides are appropriate for specific situations based on the toxicity associated with them.
