What is the primary purpose of using Personal Protective Equipment (PPE) in aerial applications?

The primary purpose of using Personal Protective Equipment (PPE) in aerial applications is to prevent pesticide exposure to applicators. Aerial applicators often work with chemicals that can be harmful to their health if they come into contact with skin, are inhaled, or are ingested. By wearing appropriate PPE—such as gloves, goggles, respirators, and protective clothing—applicators significantly reduce their risk of exposure to hazardous substances. This is crucial not only for their safety but also for compliance with health and safety regulations governing pesticide application.

Other aspects, such as enhancing communication with ground crews, improving flight performance, or keeping the aircraft clean, do not directly address the fundamental health risks associated with handling pesticides, highlighting why they are not the primary function of PPE in this context.
