How frequently must a supervisor monitor a handler using a highly toxic pesticide?

When handling highly toxic pesticides, it is crucial to ensure the safety and protection of the applicators, the environment, and public health. The regulation requiring supervisors to monitor handlers of these substances mandates that supervision occurs at least once every two hours. This frequency is important to mitigate the risks associated with exposure, as highly toxic pesticides can pose significant health hazards.

By monitoring at this interval, supervisors can ensure that handlers are adhering to safety protocols, using personal protective equipment correctly, and recognizing any signs of potential exposure. This practice is designed to provide a balance between ensuring safety and allowing handlers a reasonable amount of time to perform their duties without constant supervision.

Monitoring every 30 minutes or every hour might seem more vigilant, but the specific requirement sets clear standards that must be met to comply with regulations; therefore, two-hour intervals provide an adequate framework for supervision while emphasizing handler safety and performance.
