The need to be seen is critical for worker safety. Low visibility is a serious hazard for all workers who must perform tasks near moving vehicles or equipment. Workers must be visible to vehicle operators in all light conditions, and against complex backgrounds. The sooner a vehicle operator sees a worker, the longer the operator has to avoid an incident. High-visibility safety apparel and accessories dramatically enhance worker visibility.

The American National Standard for High-Visibility Safety Apparel and Accessories, ANSI/ISEA 107-2015, is a consensus standard that specifies requirements for apparel and accessories worn by workers to visually signal their presence. It was developed by the International Safety Equipment Association (ISEA) and first published in 1999. Since then, the standard has been recognized and compliance mandated by federal, state and local authorities as well as private industry entities.

This document was prepared by ISEA to answer some of the commonly asked questions about the standard and its relationship to federal, state and local regulations; and describe the changes in the 2015 revision.
