When someone is using a pesticide with the "DANGER" signal word, how often should others check on them?

The correct practice regarding monitoring individuals using a pesticide labeled with the "DANGER" signal word is to check on them every two hours. The "DANGER" signal word indicates a highly toxic pesticide that requires careful handling and oversight to ensure the safety of the applicator and those nearby. Regular monitoring every two hours helps ensure that any potential exposure or adverse reactions can be addressed quickly.

This interval of checking is standard because it allows enough time to assess the situation without allowing too much time to pass, which could be critical in the event of a pesticide-related emergency. Frequent checks are particularly important for high-risk scenarios involving hazardous substances, where timely intervention may be necessary to mitigate health risks.
