HIGH VISIBILITY

​High-visibility clothing, a type of personal protective equipment (PPE), is any clothing worn that has highly reflective properties or a colour that is easily discernible from any background. Yellow waistcoats worn by emergency services are a common example.

 

Part of the surface of the garment may have retroreflective stripes. This way they become much more visible in the dark for observers near a light source, such as the driver of a car with its headlights on. The pattern of the retroreflecting parts also helps to distinguish between objects and people. Area reflective fabric has proven to be the most effective way of outlining the body, so that drivers can distinguish a human shape at night.

For greater visibility during the daytime, very bright colours are used for the main body of the garment by means of fluorescent material.



EN 471

A European Standard for high-visibility clothing. It deals with High-Visibility Specifications.

Only YELLOW and Orange hi vis vests are en471 spec by law. Red vests, green vests and all other colours do not meet en471 specification  Below are some of the required codes and safety explainations for various items of Hi Visibility and Personal Protective Equipment.

EN471 - Specification for High Visibility Clothing
There are 3 classes of garment type based on the levels of conspicuity they provide. On all garments the retro-reflective tape must not be less than 50mm wide.

THE HIGHEST LEVEL OF CONSPICUITY
Minimum background material 0.80m2
Minimum retro-reflective material 0.20m2


CLASS 2

Selection of the most suitable class of garment is based on your risk assessment.
