Understanding the ANSI/ISEA 107-2015 High Visibility Standard

The ANSI/ISEA 107-2015 is the approved standard for High-Visibility Work Safety Apparel and Accessories offering garment categories of performance classes. These classes are based on worker hazards and tasks, the complexity of the job site's background and vehicular traffic and speed.

Because of the varying degrees of required visibility, industrial safety apparel is separated into three performance classes. After a hazard assessment of your work site, you should be able to determine which class is needed in your particular environment.


Type O Apparel

Meant for off-road applications, Type O provides added visibility to workers who are not exposed to traffic. Type O HVSA provides daytime and nighttime environments which pose struck-by hazards from moving vehicles, equipment and machinery.

Type R Apparel

Type R apparel offers enhanced visibility for workers who are exposed to highway traffic and working against complex backgrounds during daytime and nighttime environments. This includes exposure to vehicles using the highway for purposes of travel, roadway temporary traffic control (TTC) zones or from work vehicles and construction equipment within a roadway temporary traffic control (TTC) zone.

Type P Apparel

Enhanced visibility for off-road and roadway environments. Type P garments are ideal for emergency personnel, incident responders and law enforcement personnel. The standard requires less fluorescent background material in order to incorporate colored panels to easily identify and distinguish personnel. It also permits for shorter garments in order to make tactical access to equipment belts easier and safer.

These garments are ideal for those workers who are mostly separated from traffic that does not exceed 25 mph, and where the background is not complex enough for them to blend in with the surroundings. Situations include parking service attendants, workers in warehouses with equipment traffic, and shopping cart retrievers.

  • Type O Only

Provides the minimum amount of high-visibility materials required to differentiate the wearer visually from noncomplex work environments, in scenarios in which the struck-by hazards will not be approaching at roadway speeds, and therefore operative detection and identification. distances.


Class 2 apparel, made with more retroflective material than Class 1, is designed for workers who are near roadways where traffic speeds exceed 25 mph, or that may be working in inclement weather conditions. Those in this classification include railway workers, school crossing guards, parking and toll gate personnel, airport ground crews and law enforcement personnel directing traffic.

  • Type R & Type P

Designed to define the human form more effectively, Type R & P apparel provides for the use of additional amounts of high-visibility materials. Performance Class 2 HVSA have the potential to provide longer detection, longer identification distances, and increased conspicuity performance compared to Performance Class 1 HVSA.


This class provides the highest visibility protection for situations in which traffic exceeds 50 mph. These garments are required for workers such as roadway construction personnel and vehicle operators, utility workers and emergency responders, and include striping on the torso, arms and legs for ultimate safety protection

  • Type R & Type P

Performance Class 3 can offer greater visibility to the wearer in both complex backgrounds and through a full range of body movements by mandatory placement of background, retroreflective and combined-performance materials on sleeves and pant legs (if present).Regardless of the area of materials used, a sleeveless garment or vest alone shall not be considered Performance Class 3.

  • Supplemental Class E

Class E apparel includes pants, bib overalls, shorts, and gaiters. These garments are not compliant when they are worn alone, though, when combined with Class 2 or Class 3 apparel, the combination satisfies Class 3 requirements.


Roadwork, railyard, construction and emergency response tasks are not limited to just the daytime, and it's critical to be easily seen in all light conditions and backgrounds. From safety vests to work shirts, through to warm winter jackets that keep workers safe and seen no matter what the job, PIP® offers hi-viz garments for all conditions, climates and applications where workers are at risk.  Now all you need to do is hit the link and ...
