Reflective safety vests are required by ANSI if you work around traffic or heavy machinery. ANSI requires different amounts of retro-reflective material that need to meet specified performance criteria, the width and placement of the material, the design, and the color of safety vests. We carry ANSI certified reflective safety vests in lime and orange. Class II ANSI vests are designed for workers who are exposed to roadways with traffic greater than 25 miles per hour or who need to have higher visibility in poor weather conditions. ANSI Class II reflective safety vests are ideal for railway workers, school crossing guards, parking and toll gate personnel, airport ground crews and law enforcement personnel directing traffic. ANSI Class III safety reflective vests provide the highest level of visibility and are designed for workers exposed to traffic exceeding 50 miles per hour and high risk environments. ANSI Class III safety vests are ideal for all roadway construction personnel and vehicle operators, utility workers, survey crews, emergency responders, railway workers and accident site investigators.
