High visibility, or hi vis clothing, is a type of apparel that workers wear to improve their visibility on a jobsite. It is most frequently worn to alert drivers and other equipment operators of where workers are located. It’s essential in dangerous conditions, such as in close proximity to roadways, in dark conditions, and in areas where workers might be blocked by trees, traffic barriers, or construction equipment. Hi vis clothing includes vests and shirts, jackets, pants, coveralls, gloves, hats and accessories that combine fluorescent materials for daytime visibility with retroreflective materials to enable workers to be seen at night. Also included are hi vis vests for public safety workers such as police, fire services and emergency responders.
Nowadays, this product is used in many occasions and has become the first choice for outdoor workers to ensure their own safety.
