What does it mean if a substance has a signal of "CAUTION"?

A substance labeled with a signal of "CAUTION" indicates that it is slightly toxic. This classification is used to inform users that while the substance can pose some level of risk, it is generally less hazardous compared to substances that carry more severe warnings. The "CAUTION" signal alerts individuals to handle the substance carefully, as moderate or even high toxicity substances would have more prominent warnings. Understanding this classification is essential for the safe handling and application of pesticides, ensuring that users are aware of the necessary precautions without causing unnecessary alarm over a relatively low toxicity level.
