What is the purpose of a reflective vest when working on antenna towers?

The purpose of a reflective vest when working on antenna towers is primarily for visibility and safety. When individuals are operating in potentially hazardous environments, such as near roadways or in low-light conditions, wearing a reflective vest enhances their visibility to others, such as passing vehicles or nearby workers. This increased visibility helps to prevent accidents by ensuring that others can see the person working on the tower, thereby reducing the risk of collisions or other dangerous situations.

Reflective vests are commonly used in various occupations where visibility is critical, especially in construction and outdoor work environments. The design typically includes bright colors and reflective strips that reflect light, making the wearer more noticeable, especially in areas where visibility may be compromised. While the other options mention important safety mechanisms related to working on towers, the primary role of a reflective vest directly relates to enhancing visibility, which is crucial for worker safety.
