What PPE must be worn at all times while on the Aircraft Operations Area (AOA)?

The requirement to wear a safety vest and hearing protection while in the Aircraft Operations Area (AOA) is critical for ensuring the safety of personnel who are exposed to various hazards in this environment. The safety vest serves to enhance visibility, which is particularly important in potentially chaotic and busy areas with aircraft movement, ground vehicles, and personnel. High visibility helps to prevent accidents by allowing those operating vehicles or aircraft to see ground workers more easily.

Hearing protection is equally important in the AOA, where noise levels can be exceptionally high due to aircraft engines and ground support equipment. Prolonged exposure to loud noise can lead to hearing loss or impairment, making hearing protection a necessary part of personal protective equipment (PPE) in this setting.

While other forms of PPE like safety helmets, goggles, respirators, gloves, steel-toed boots, and high-visibility clothing are essential in specific contexts or tasks, the combination of a safety vest and hearing protection is universally mandated for all employees operating in the AOA to ensure their overall safety and compliance with industry standards.
