What does the presence of a caution signal word on a pesticide label generally indicate?

The presence of a caution signal word on a pesticide label typically indicates that the product is considered to have a lower level of toxicity compared to other classifications. In the context of pesticide labeling, signal words help users understand the toxicity level and the potential risks associated with the use of the chemical.

When a pesticide is labeled with "caution," it signifies that while the product may still pose some risk, it is not highly toxic or life-threatening. This categorization places it in a more moderate range, suggesting that users should handle it with care, but it does not necessitate the higher level of precautions that would be associated with terms like "danger" or "warning." The signal word serves to guide consumers and applicators in assessing the necessary safety measures when using the pesticide.

In contrast, labels that indicate higher toxicity might employ more alarming terms, signifying a greater risk of causing acute illness or serious harm. Thus, "caution" effectively communicates that while the pesticide may still require careful handling, it is not among the most hazardous substances.
