Classes of Hi-Vis Clothing

Hi-Vis Jacket

High-visibility clothing is a must in some work environments – think construction, on the flight line and in asset recovery operations – but there are different levels of hi-vis apparel. Each of the three classes, created by the American National Standards Institute (ANSI), fits certain risk levels. Most employers, and in some cases the Occupational Safety and Health Administration (OSHA), require workers in risky professions to wear Class 1, Class 2 or Class 3 visibility apparel. Supplemental items feed into Class E reflective apparel, which provides the highest level of visibility. In addition to the three classes, there are three official types: Type O, Type R and Type P. Each refers to different professions that are using hi-vis or reflective apparel, including high-visibility jackets, hi-vis parkas, and other clothing.

What Are the Three ANSI Hi-Vis Classes?

The following are the three main ANSI hi-vis classes: • Class 1. Class 1 is for off-road use and provides the lowest level of protection. It’s often used by parking attendants, warehouse workers and people working off the roadway. • Class 2. Class 2 is for roadway use and provides a moderate level of protection. This class is typically best for school crossing guards, airport ground crews and people who are directing traffic in an official capacity. • Class 3. Class 3 is also for roadway use, but it provides the highest level of protection. It’s effective for road construction workers, utility workers, survey crews and emergency responders, as well as other people who work near traffic.

Type O, Type R and Type P Visibility Garments

Aside from the ANSI hi-visibility classes, there are several types of hi-vis garments designed for specific professions. You’ll find a wide range of apparel that fits into each type, including vests, jackets, and parkas. Here’s a breakdown of each type:

  • Type O. Type O apparel is designed for workers who aren’t required by OSHA to wear hi-vis garments, but who still work in hazardous environments where visibility is a concern.
  • Type R. Type R garments are for workers who are exposed to traffic or those who work in a place with moving equipment or vehicles.
  • Type P. Type P apparel is typically designed for police, fire and EMS personnel who deal with roadway hazards and other hazards.
