Hi Vis clothing or HV clothing, is the short form for High Visibility clothing. This type of clothing has been mainly introduced in the form of Hi Vis Jackets. Hi Vis Jackets are a kind of Personal Protective Equipment that make the wearer conspicuous even in poor light, thus preventing accidents that may have otherwise occurred due to poor visibility.
Hi Vis jackets are now an essential feature of the uniforms worn by a vast number of workers, including those personnel who work as construction workers, traffic policemen, railway track workers, search and rescue mission operatives, linesmen, ground handling personnel on airside as well as pilots.
Hi Vis jackets are also worn nowadays by early morning joggers and pedestrians. As people become more and more aware about personal safety and the different methods of accident prevention available to them, the market for Hi Vis Jackets has been expanding at an impressive rate. This is a result of awareness and increased amounts of available information.
The federal law in the United States of America has made it legally binding for workers working on highways to wear Hi Vis jackets or vests.
Hi Vis jackets are mainly made of fluorescent fabric or dyed with fluorescent dyes.
