In pesticide labeling, what does the 'caution' signal word indicate?

The 'caution' signal word on pesticide labeling indicates that the product is considered to be slightly toxic. This classification system is a way to communicate the level of toxicity and potential risk associated with pesticide products.

Signal words are part of the labeling requirements for pesticides and are critical for informing users about the safety and handling of the chemical. The terms 'caution', 'warning', and 'danger' establish a hierarchy of toxicity; 'caution' signifies the least degree of toxicity among these classifications, meaning that while the product can still pose risks to health and the environment, the risks are not as severe as those indicated by higher toxicity ratings. Therefore, it is essential to understand that even though 'caution' suggests a lower toxicity, precautions should still be followed when handling these products.
