Which term describes a substance that has slight toxicity?

The term that describes a substance with slight toxicity is "CAUTION." In the context of pesticide labeling, different signal words signify the level of toxicity associated with a product. “CAUTION” indicates that a pesticide is mildly toxic, generally requiring users to exercise care and follow specific precautions while using it. This term suggests a lower level of hazard compared to terms like "DANGER," which denotes high toxicity, and “WARNING,” indicating moderate toxicity.

While "relatively non-toxic" may imply that a substance poses minimal risk, it is not an official label or classification used in pesticide regulation. The use of established terms like "CAUTION" ensures clarity and consistency in communication about the toxicity and hazards of chemical products, guiding users in their safe handling and application. Understanding these signal words is crucial for pesticide applicators to ensure safe practices in their work environment.
