What essential equipment must aerial applicators use for safety?

The essential equipment that aerial applicators must use for safety is personal protective equipment (PPE). PPE is critical as it provides a barrier against various hazards associated with aerial application, including exposure to chemicals, potential physical injuries, and environmental factors. Items commonly included in PPE for aerial applicators are gloves, goggles, respirators, and protective clothing, which help to reduce the risk of chemical exposure and enhance safety during operations.

While some other equipment, like navigation aids and drones, can enhance operational efficiency and safety if used correctly, they do not primarily address the specific safety concerns related to the applicator's personal protection. Similarly, binoculars and compasses, along with heaters and fans, serve other purposes, such as navigation or improving comfort within the aircraft, but they do not provide personal safety in the context of handling pesticides or hazardous materials. Therefore, PPE is fundamentally necessary for ensuring the health and safety of aerial applicators during their work.
