The need for hi-viz wear in dangerous occupations is readily apparent when we see workers constructing a roadway or on a construction site where vehicles and other equipment might pose a threat if the worker is not clearly visible. But for some occupations, being seen is only one part of the safety equation. Arcs, electric sparks, and flash fires pose a threat to those working in jobs such as welding, electrical responders, and those working in facilities where there are flammable materials and reactive chemicals posing a risk of flash fires. For these occupations, fire retardant and arc resistant clothing are a must.
Today's hi-viz fire retardant clothing not only meets the criteria for flame resistance but is also comfortable and available in ranges to meet ANSI Standards for safety and visibility. Non-durable flame resistant garments will be flame resistant until washed, but the durable flame resistant apparel, made of modacrylic fibers, will retain flame resistance after repeated washing. These modacrylic fibers are also excellent in their ability to resist chemicals and solvents while also being resistant to things such as mildew and moths.
So if your job demands the most in safety, choose apparel that gives the most in performance.
