ANSI High-visibility Clothing Standard

Protect your workers by following the ANSI standard for high visibility clothing

Do your employees work near vehicular traffic? Then they must wear high-visibility clothing so that they can be seen by motorists.

Hi-visibility Clothing

ANSI/ISEA 107 Standard
The ANSI/ISEA 107 standard is the uniform, authoritative guide for the design, performance specifications and use of high-visibility and reflective clothing for employees. The standard specifies the types, classes and colors of high-visibility safety garments required based on wearer’s activities and nearby vehicle and equipment speeds.

Worker Visibility Standard
In addition, a final rule was issued to the Manual on Uniform Traffic Control Devices (MUTCD) that requires all workers within the right of way of any roadway open to public travel to wear Class 2 or Class 3 ANSI/ISEA 107-2011 compliant high-visibility safety apparel effective December 31, 2011.

This rule also applies to people on foot whose duties place them within the right of way of any roadway open to public travel, including roads on private property. This includes construction, maintenance, survey and utility crews as well as first responders and law enforcement personnel responding to incidents or traffic-related issues within the right of way of any public roadway.
