Introduction to EN ISO 20471
EN ISO 20471 sets the international standard for high visibility clothing. It improves worker safety in low visibility environments. This standard sets clear requirements for fluorescent materials, reflective tape, and garment design. It helps workers stay visible in daylight and low-light conditions.
High visibility clothing certified to EN ISO 20471 is widely used by construction workers, road maintenance crews, warehouse staff, logistics personnel, airport ground teams, and emergency responders.
Why Is EN ISO 20471 Important?
Workers operating near moving vehicles or heavy equipment face significant visibility risks. Poor visibility can increase the likelihood of accidents, particularly during nighttime operations, adverse weather conditions, or busy traffic situations.
EN ISO 20471 helps improve safety by:
- Increasing worker visibility during the daytime
- Enhancing visibility at night through reflective materials
- Providing consistent performance requirements
- Supporting workplace safety programs
- Helping employers meet project safety requirements
Key Requirements of EN ISO 20471
The standard evaluates several aspects of high visibility clothing:
Fluorescent Background Material
Reflective Tape
Garment Design
EN ISO 20471 Classes Explained
The standard classifies garments into three visibility levels.
| Class | Visibility Level | Typical Applications |
| Class 1 | Lowest | Low-risk work environments |
| Class 2 | Medium | Warehouse, logistics, and light construction |
| Class 3 | Highest | Highway maintenance, road construction, and high-risk traffic areas |
Class 3 high visibility clothing provide the highest level of visibility and are commonly used in roadwork and infrastructure projects.
