High visibility garments issued to employees should conform to all relevant performance standards (EN ISO 20471, European standard for High Visibility Clothing), and should be worn and maintained correctly for maximum protection.

In order to comply with all UK and European legislation, you need to ensure that the high visibility garments you buy comply with the
following: High visibility clothing conforming to Class 1, 2, or 3, which must be worn at all times.

The colour of the background materials should normally be fluorescent yellow or fluorescent orange. The retro-reflective material
enhances your visibility in low light situations. This reflective material returns light to a light source - such as vehicle headlights - creating a bright image that motorists are more likely to see from a distance. As a result, motorists and pedestrians have more time to react.
