What type of vest is required for personnel working in a workzone?

The requirement for personnel working in a work zone is to wear a reflective vest. This type of vest is essential for ensuring visibility, especially in low-light conditions or when visibility is reduced due to weather or the environment. Reflective materials help to enhance the visibility of workers, making it easier for drivers to see them and thereby reducing the risk of accidents.

The use of reflective vests is a critical safety measure as it provides a clear indication of the presence of workers on or near roadways, allowing vehicle operators to take appropriate precautions. This is in line with OSHA standards, which emphasize the importance of visibility in protecting workers in active traffic areas.

In contrast, frayed, colored, or heavy-duty vests do not necessarily include the reflective elements that are crucial for adequate visibility in work zones, thus making them less suitable for ensuring the safety of personnel in these high-risk environments.
