High visibility clothing is any clothing worn that has highly reflective properties or a color that is distinct from any background. Yellow maintenance vests are a good example of
High visibility clothing.
Part of the surface of clothes may be made retroreflective (small parts of coats, large parts of special safety clothes for rescue workers etc.). 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.
For greater visibility at daytime, as well as for decoration, very bright colors are obtained with fluorescence. People working near traffic, mobile plant or equipment are regularly exposed to potential hazards, with the serious risk of impact.
High visibility clothing, as a form of personal protective equipment, does not establish a safe system of work in itself. In the order of control measures, high visibility clothing is among the least effective methods of controlling the risks associated with working near traffic, mobile plant or equipment under operator control.
You should only consider the use of this clothing if, after implementing other controls, some risk to the worker still remains (e.g. emergency and other services working adjacent to traffic) or when other control measures are impractical.
