ANSI/ISEA 107 Explained: Choosing the Right Hi-Vis Class for Your Job
The ANSI/ISEA 107 standard is the benchmark for high-visibility safety apparel in the United States. Understanding its classification system is essential for employers and safety managers who need to select the correct PPE for their workers.
Background Material Requirements
ANSI/ISEA 107 specifies minimum amounts of fluorescent background material based on performance class. The three approved colors are:
- Fluorescent Yellow-Green: Highest daytime visibility, ideal for low-light or shaded environments
- Fluorescent Orange-Red: Best contrast against natural backgrounds, preferred for road work
- Fluorescent Red: Used in specific applications such as emergency responders
Retroreflective Tape Requirements
Retroreflective tape must meet minimum width (2 inches) and placement requirements. Combined-performance material — which is both fluorescent and retroreflective — can be used to meet both requirements simultaneously.
Performance Classes at a Glance
- Class 1 (Type O — Off-Road): Parking lot attendants, warehouse workers away from vehicle traffic. Minimum 217 sq in background material.
- Class 2 (Type R — Roadway): Road construction workers, survey crews, school crossing guards. Minimum 775 sq in background material.
- Class 3 (Type R — Roadway, highest risk): Highway workers, emergency responders, utility workers near high-speed traffic. Minimum 1,240 sq in background material.
Type P — Public Safety
A separate Type P classification exists for police, fire, and EMS personnel who need high visibility combined with other protective features.
How to Choose
Match the class to the risk level. When in doubt, choose a higher class — over-protection is never a problem. RANOVA USA can help you assess your work environment and select the right class for your team.
