What section includes details about signals and warnings related to a pesticide's toxicity?

The section that includes details about signals and warnings related to a pesticide's toxicity is the one that focuses specifically on precautionary measures. Precautionary statements are critical because they provide specific information on the potential health hazards associated with the pesticide, ensuring users are aware of the risks. These statements often include signal words like "Danger," "Warning," or "Caution," which indicate the level of toxicity and necessary safety measures to take. By highlighting these warnings, the section serves to protect individuals from exposure and facilitates safe handling and application of the pesticide.

In contrast, first aid sections deal primarily with responses and treatments for exposure incidents, while dangers and precautions provide general safety information. Storage and disposal sections cover guidelines for safely managing the pesticide after use, lacking the specific hazard warnings related to toxicity that precautionary statements present.
