High-visibility (hi-vis) clothing standards are governed by regulations that ensure worker safety in environments with poor visibility or high-risk conditions, such as construction sites or roadworks. The key standard is EN ISO 20471, which specifies the requirements for visibility, color, and retroreflective material.
Hi-vis clothing must meet these criteria:
- Class 1, 2, or 3: Defines the level of visibility, with Class 3 offering the highest visibility.
- Fluorescent colors: Typically yellow, orange, or red for daytime visibility.
- Retroreflective strips: To improve visibility in low-light conditions, such as nighttime.
