What type of activities require the use of Class 3 vests?

Class 3 vests are designed to provide the highest level of visibility for workers in environments where there is a high volume of vehicle traffic. These vests feature retroreflective materials that enhance visibility from a distance, ensuring that they stand out even in potentially dangerous conditions.

The need for extreme visibility arises particularly in situations where workers are in close proximity to moving vehicles or machinery, such as construction sites or busy roadways. These vests are essential in protecting personnel by making them clearly identifiable to drivers and others in the area, thus minimizing the risk of accidents.

While low traffic work or nighttime operations may require specific types of personal protective equipment, Class 3 vests are particularly critical in high-traffic scenarios where visibility is paramount. General public safety is a broader category that does not specifically address the reflective requirements for Class 3 vests. Therefore, the emphasis on extreme visibility work reflects the specific need for such equipment in high-risk environments.
