What Does High Visibility Safety Apparel (HVSA) Mean?
High visibility safety apparel (HVSA) is clothing that workers wear in order to improve their visibility. HVSA is commonly used on work sites where there are drivers of any sort of equipment and particularly when the work site may be dark. Other scenarios where HVSA may be required are working in the wilderness, hunting, or when a worker's body may be hidden. HVSA includes reflective vests, hard hats, coveralls and bibs.
