High visibility (Hi Vis) is clothing that is made to make the wearer highly visible in low light. Bright hues like yellow or orange and reflective elements like stripes or tape are common in hi-vis clothing, which helps to reflect light from headlights and other sources.
People working in dangerous areas, such as construction sites, where visibility is poor and the potential of accidents is great, require this kind of apparel. To ensure that they are quickly identified in emergency circumstances, emergency services personnel like police, paramedics, and firefighters frequently wear hi-visibility work clothing. Hi-visibility work attire can increase safety and lower the possibility of workplace accidents.
