During an application operation, when must pilots wear label-required personal protective equipment?

Pilots must wear label-required personal protective equipment (PPE) while making nozzle adjustments to ensure their safety and compliance with pesticide label requirements. This specific activity involves direct handling and potential exposure to chemicals, as nozzle adjustments can lead to spills or sprays of the pesticides being applied. The use of PPE, such as gloves, goggles, and respirators, protects pilots from harmful substances, minimizing the risk of exposure and ensuring their health during these critical operational tasks. Following these guidelines is essential to maintain safety standards within aerial application operations.

In contrast, activities like filing reports, conducting flight checks, or taking breaks generally do not involve the same risk of chemical exposure, thus the requirement for PPE is not as stringent during those tasks.
