According to the National Institute for Occupational Safety and Health (NIOSH), work zone crashes remain a leading cause of occupational injuries. In this guide to ANSI Safety Apparel Ratings, we'll break down how the standard's Types (O, R, P) and Classes (1–3) help you choose life-saving high-visibility gear for every work environment.
Understanding ANSI Safety Apparel Ratings helps you choose the right protection for your specific work environment and keeps your team safe from preventable accidents. The American National Standards Institute sets these ratings to regulate apparel visibility and protection across different industries, ensuring workers remain visible to equipment operators, drivers, and other personnel who might otherwise miss them in busy work zones.
The Basics of ANSI Safety Apparel Ratings
ANSI began developing safety standards in 1918, evolving from the American Engineering Standards Committee into today's comprehensive standards organization. The first high-visibility safety apparel standard, ANSI/ISEA 107-1999, was largely based on existing European standards and has undergone regular updates to improve worker protection.
The current standard, ANSI/ISEA 107-2020, combines fluorescent background materials with retroreflective strips to make workers visible in various lighting conditions while organizing safety apparel into three distinct types based on work environment:
Type O (Off-Road) garments protect workers in non-roadway environments like warehouses and loading docks. These workers face vehicle hazards but don't work near public roads.
Type R (Roadway) apparel meets requirements for workers exposed to roadway traffic. This includes construction crews, utility workers, and anyone working within road rights-of-way.
Type P (Public Safety) gear serves law enforcement and emergency responders who need quick access to equipment while maintaining visibility. These garments often feature shorter designs to accommodate duty belts and gear.
Each type comes in different performance classes that determine the amount of visible material required. The ANSI/ISEA 107-2020 standard specifies exact material requirements for each combination:
- Type O Class 1 – 217 in² background, 155 in² reflective
- Type R Class 2 – 775 in² background, 201 in² reflective
- Type R Class 3 – 1,240 in² background, 310 in² reflective
- Type P Class 2 – 450 in² background, 201 in² reflective
- Type P Class 3 – 775 in² background, 310 in² reflective
All ANSI-compliant garments must carry a label indicating ANSI/ISEA 107-2020 compliance, the garment Type, and Performance Class. This classification system ensures workers get appropriate protection based on their specific hazards and work environments.
Key Differences in ANSI Safety Apparel Ratings
ANSI classes differ significantly in their visibility requirements and material specifications. Understanding these differences helps you select appropriate protection for each work situation.
Class 1 ideal for low-risk zones (warehouses, parking lots).
Class 2 ideal for road construction workers, airport ground crews, and flaggers typically wear Class 2 apparel. The Manual on Uniform Traffic Control Devices requires Class 2 or higher for all roadway workers (MUTCD Section 6D.03) [FHWA].
Class 3 garments resemble short-sleeve shirts due to their extensive coverage requirements. Class 3 apparel suits high-speed traffic environments, nighttime operations, and situations where workers cannot devote full attention to surrounding hazards.
The retroreflective strips must provide 360-degree visibility with horizontal gaps of 50mm or less. Garments without reflective sleeves need additional shoulder reflective material to maintain proper visibility angles.
Selecting the Right Apparel for Your Work Environment
Choosing appropriate ANSI-rated gear depends on your specific work conditions and regulatory requirements. Different job roles demand different protection levels based on traffic speed, equipment proximity, and environmental factors.
Delivery drivers and warehouse workers typically need Class 1 protection when working in controlled environments with slow-moving vehicles. Municipal workers, construction crews, and airport personnel require Class 2 apparel for medium-risk environments with moderate traffic speeds.
Highway construction workers, emergency responders, and utility crews working near high-speed traffic need Class 3 protection. Survey crews and tow truck operators also benefit from maximum visibility apparel due to their exposure to fast-moving vehicles.
Background materials come in fluorescent yellow-green, fluorescent orange-red, and fluorescent red to maximize daytime visibility. Consider seasonal requirements when selecting safety apparel. Safety winter gear maintains ANSI compliance while providing cold-weather protection. Waterproof rain gear keeps workers visible and dry during adverse weather conditions.

Proper Care and Maintenance for Longevity
Maintaining high-visibility apparel preserves its protective properties and extends service life. Proper care practices keep retroreflective materials effective and background colors bright.
Machine wash safety apparel in cold water using mild detergents. Avoid bleach and fabric softener, which can damage retroreflective strips and fade fluorescent colors. Don't wash high-visibility clothing with rough fabrics like denim that might damage adhesive bonds.
Inspect garments before each shift for signs of wear, fading, or damage. Clean visible dirt and dust after each use to maintain optimal visibility. Check retroreflective strips for peeling, cracking, or loss of reflectivity. Best practices recommend inspecting reflective strips for cracking or delamination.
Replace daily-use hi-vis apparel every six months; occasional-use garments may last up to three years, depending on wear and care [BorderStates]. Replace apparel that shows fading, tears, or reduced reflectivity. Garments should remain visible at 1,000 feet during both day and night conditions. Effectiveness matters more than age when determining replacement needs.
Proper storage in cool, dry locations away from direct sunlight helps preserve fluorescent colors and retroreflective properties. Regular maintenance and timely replacement ensure continuous compliance and optimal worker protection.
