Understanding ANSI/ISEA 107 & EN ISO 20471 Visibility Standards

The ANSI/ISEA 107 and EN ISO 20471 standards establish internationally recognized requirements for high-visibility safety apparel, helping workers remain visible in low-light conditions and hazardous work environments.

These standards define garment design, fluorescent background materials, reflective tape placement, and minimum visibility requirements to improve worker safety. Although both standards share the same goal of enhancing visibility, they use different classification systems and performance requirements. Understanding these differences helps employers choose the right high-visibility PPE for specific industries, job roles, and workplace hazards.

ANSI/ISEA 107 Garment Types & EN ISO 20471 Classes

Both ANSI/ISEA 107 and EN ISO 20471 establish requirements for high-visibility safety apparel, but they classify garments differently.

  • ANSI/ISEA 107 Standard: Categorizes garments into Type O, Type R, and Type P based on work environment and potential hazards, while assigning Performance Classes 1, 2, and 3 to indicate visibility levels.
  • EN ISO 20471 Standard: Classifies garments solely by Class 1, Class 2, and Class 3 based on the minimum required area of fluorescent background material and retroreflective tape.
  • Compliance & Selection: Understanding both standards helps employers choose the right high-visibility PPE for their workplace while meeting regional safety requirements.

ANSI/ISEA 107 & EN ISO 20471 Visibility Classes

Both ANSI/ISEA 107 and EN ISO 20471 classify high-visibility safety apparel to help workers remain visible in hazardous environments and reduce the risk of workplace accidents.

ANSI/ISEA 107 Classes

  • Class 1 – Designed for low-risk environments with minimal traffic and lower visibility hazards.
  • Class 2 – Recommended for workers near roadways or equipment operating above 25 mph, including construction crews, utility workers, and survey teams.
  • Class 3 – Provides the highest level of visibility for high-risk environments such as highways, road maintenance, and emergency response.
  • Class E – Supplemental garments, including high-visibility pants, bib overalls, and gaiters, that must be worn with Class 2 or Class 3 upper-body garments to achieve a Class 3 ensemble.

EN ISO 20471 Classes

  • Class 1 – Basic visibility for low-risk work environments.
  • Class 2 – Enhanced visibility for workers exposed to moderate traffic and industrial hazards.
  • Class 3 – The highest level of visibility, offering maximum fluorescent and reflective coverage for high-risk work environments.
