WHAT are Performance Class and Garment Type desig- nations, and how do they impact product selection? When it comes to high-visibility clothing, there are many options. With different color-ways, reflective tape patterns, sleeve lengths, it can be tricky choosing the right apparel for the job. The ANSI/ ISEA 107-2015 standard, which is voluntary, sets forth what is an approved fluorescent material and reflective tape, as well as what level of brightness and coverage are recommended for various kinds of work environments.
ANSI 107 sets forth four performance classes (Class 1, 2, 3, and E) and three garment types (Type O, P, and R) of high- visibility apparel.
Performance Class 1 garments offer the minimum amount of high-visibility materials needed to differentiate the wearer from non-complex work environments, such as in warehouses. On the other side of the spectrum, Class 3 apparel offers the greatest amount of high-visibility materials to allow for the best definition of the human form in both complex backgrounds and through a full range of movement. Class 3 performance clothing is typically worn by road or maintenance workers in highway work zones. Class 2 garments fall between the other two in the amount of back- ground and retroreflective materials.
In addition, Class E describes pants or bibs. When worn with Class 2 or Class 3 vests, shirts, etc., the total ensemble of pants/bibs and tops is classified as Class 2 or Class 3.
In addition to the performance classes, the ANSI standard also establishes three garment types: Type O for work that takes place off-road or in controlled environments, Type R intended for roadways, and Type P intended for public safety workers. Perfor- mance class and garment type are co-dependent, which means that to qualify under the ANSI standard, the apparel must have both a class and a type (not just one or the other). The chart in this ar- ticle provides some general guidelines that can help in choosing the right clothing.
