ANSI/ISEA 107 High Visibility – 2015
ANSI/ISEA 107-2015 is the American National Standard for High Visibility Safety Apparel and Headwear. The industry standard developed by the American National Standards Institute provides a uniform, authoritative guide for the design, performance specifications, and use of High Visibility and reflective apparel including vests, jackets, bib/jumpsuit coveralls, pants, and harnesses. Garments that meet this standard can be used at work 24 hours a day to provide users with a high level of conspicuity through the use of combined fluorescent and retro-reflective materials.
ANSI/ISEA 107 Performance parameter:
High Visibility Garment Types are designated by the work environment in which the wearer is performing a task. There are 3 types as shown on the table below – Type O, Type R and Type P.
Performance Classes provide a range of design options corresponding with the needs of the user in the expected risk environment.
Class 1 (Type O) is worn in non-complex work areas in which vehicles will not be moving at roadway speeds.
Class 2 (Type R or P) uses more high visibility material than Class 1 which allows the HVSA to define the human more effectively.
Class 3 (Type R or P) can offer greater visibility to the wearer in both complex backgrounds and through a full range of body movements by the mandatory placement of background material and reflective tape on sleeves, legs, etc.
Class E Supplemental Items such as pants, overalls, shorts, and gaiters shall not be worn alone to meet HVSA PPE requirements. When a Class E item is worn with Performance Class 2 or Class 3, the overall classification shall be Performance Class 3.
