What is the significance of the signal word CAUTION on pesticide labels?

The signal word CAUTION on pesticide labels serves an important function in indicating that the pesticide in question requires careful handling and a heightened awareness of potential hazards. This signal word is associated with products that have low toxicity; however, that does not imply that they are completely without risk. The CAUTION label alerts users to the fact that, while the product may be safer compared to those labeled WARNING or DANGER, it still necessitates prudent use and respect for safety protocols. Users should be mindful of how they handle, apply, and store these products to mitigate any risks associated with their use.

The other options imply various meanings that do not accurately reflect the purpose of the signal word. For example, labeling a pesticide as safe for general use oversimplifies the complexities of handling chemicals, which can still pose dangers even when classified as low toxicity. Similarly, though CAUTION indicates low toxicity, the label does not eliminate the need for safety training or awareness; therefore, the notion that training is not required overlooks essential safety practices and legal requirements.
