When is it advisable to use reflective vests on a job site?

Using reflective vests on a job site is primarily advisable in poor visibility conditions. Reflective vests are designed to enhance the visibility of workers, making them more noticeable to both vehicle operators and other personnel on the site, especially in situations where visibility may be compromised. This includes low-light conditions, such as dawn, dusk, and during inclement weather.

While reflective vests are beneficial at night and in scenarios where crews are working above ground, relying solely on those situations can lead to safety oversights. Additionally, wearing them throughout the day regardless of conditions may not be strictly necessary and could be seen as redundant in areas with ample lighting and clear visibility. Therefore, using reflective vests specifically in poor visibility conditions ensures that safety protocols are effectively targeting the most critical moments for worker safety.
