In which of the following situations is there an exception to the regulation requiring employee handlers to wear eye protection when handling pesticides?

The correct answer is based on specific regulatory provisions that address safety measures for employee handlers of pesticides. The regulation regarding mandatory eye protection is formulated to minimize the risk of exposure to harmful chemicals. However, there are exceptions, and working in an enclosed cab is one of them.

When employees are operating equipment that is enclosed, such as a tractor or other machinery designed to house the operator safely, the risk of pesticide exposure to the eyes is significantly reduced. The design of the cab minimizes the chances of pesticide drift or splatter reaching the operators, thereby removing the necessity for eye protection in that specific context.

In contrast, situations like mixing pesticides, working in poorly ventilated areas, or during stormy weather present different exposure risks that warrant the use of eye protection to ensure the safety of the handlers. Therefore, the enclosed cab exception recognizes a specific scenario where the risk is mitigated, making it unnecessary to adhere to the eye protection requirement.
