What should applicators do if they are working with highly toxic organophosphate or carbamate insecticides?

When working with highly toxic organophosphate or carbamate insecticides, it is essential for applicators to check their cholinesterase level. These types of insecticides can inhibit the enzyme cholinesterase, which is crucial for the proper functioning of the nervous system. Monitoring cholinesterase levels helps to assess exposure to these chemicals and can be a critical part of a safety program.

By regularly checking these levels, applicators can determine whether their exposure to these pesticides is within safe limits and whether they need to take additional health precautions. If cholinesterase levels are found to be low, it may be an indication of overexposure, which can lead to serious health complications. This proactive approach is crucial in ensuring the safety and health of those handling these toxic substances.

Other options suggest immediate medical attention or inappropriate practices that do not address the necessary precautions required when working with such hazardous materials.
