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 ANSI Class 3 standard specifies the types, classes and colors of high-visibility safety garments required based on wearer’s activities and nearby vehicle and equipment speeds. 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.
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. ANSI Class 2 is worn when workers are on or near roadways, nearby vehicle and equipment speed: 25 to 50 mph, as well as roadway construction workers. ANSI Class 3 is required when workers are in high-risk situations. Allows them to be seen from a minimum distance of 1,280 feet, vehicle and equipment speed that exceeds 50 mph. Safety gear is ideal for utility workers, survey crews, law enforcement personnel, school crossing guards, railway workers, accident investigators, emergency personnel and others.
