Lack of visibility gives rise to the risk of being hit by a vehicle, both during the day and at night.
High visibility clothing is covered by standard EN 471.
The larger the area of fluorescence and reflectivity of a wearer's clothing, the more he or she will be visible and, therefore, protected against the risk of poor visilbility.
Directive 89/686/EEC, Annex II, Art. 2.13: PPE in the form of clothing capable of signalling the user's presence visually
"PPE in the form of clothing intended for foreseeable conditions of use in which the user's presence must be visually and individually signalled must have one (or more) judiciously positioned means of or emitting direct or reflected visible radiation of appropriate luminous intensity and photometric and colorimetric properties."
Elis offers a complete range of high-visibility PPE items that comply with the various requirements of standard EN 471.
