Where can first-aid instructions for pesticide exposure typically be found?

The correct choice is that first-aid instructions for pesticide exposure can be typically found on pesticide labels. Pesticide labels are essential documents that provide critical information about the safe and effective use of the product. They are legally required to include clear instructions on what to do in case of a pesticide exposure, including the appropriate first-aid measures. This information is designed to be readily accessible and easily understandable, ensuring that users can quickly respond in an emergency situation.

While other sources like OSHA's Emergency Response website, supplemental labeling, and manufacturer literature may contain relevant safety information and guidelines, pesticide labels are specifically mandated to feature first-aid instructions as part of their regulatory requirements. This makes pesticide labels the most direct and reliable source for first-aid instructions in scenarios of pesticide exposure.
