1. What EN ISO 20471 covers
EN ISO 20471 organizes garment visibility according to the amount and placement of fluorescent and reflective material.
In practice, it helps distinguish garments for occasional support, work around machinery or stronger exposure to traffic and low light.
- Class 1 for lower exposure.
- Class 2 for intermediate visibility.
- Class 3 for maximum wearer visibility.
2. Different roles need different choices
A delivery driver, a public works operator and an outdoor warehouse team do not share the same risk.
B2B buying should separate roles, shifts and environments to avoid under-specifying or over-specifying the whole workforce.
The point is not buying more yellow. The point is matching the right class to the real risk.
3. Logo, washing and replenishment
Customization must respect visible areas and avoid covering critical reflective material.
It is also worth defining a stable reference by role, because improvised replenishment often breaks color, class or sizing consistency.
- Define class by role.
- Validate marking area.
- Store references and sizes.
- Review wear and washing.
