The most common personal protective equipment (PPE) used when installing access points (APs) on high ceilings includes items designed for both safety and visibility in potentially hazardous work environments. Utilizing a hard hat protects the worker's head from falling objects, which is crucial when working at height. A high visibility vest ensures that the worker is easily seen, reducing the risk of accidents in busy areas where machinery or other workers might be present. Lastly, a body belt offers support and safety while working at elevation, helping to prevent falls.

In contrast, the other options do not address the specific hazards associated with installation at heights. Glasses, gloves, and jackets are typically more relevant for tasks that involve electrical work or chemical handling rather than the physical dangers of falling. Clean suits, masks, and glasses or gloves and jackets are generally used in environments requiring contamination control rather than in situations where visibility and the physical safety of the worker are paramount. Thus, the combination of hard hat, high visibility vest, and body belt is tailored to the safety needs of high-altitude installation work.
