Class 2 apparel is necessary for workers exposed to traffic traveling over 25 mph and who work against complex backgrounds.
FR treated material is designed to prevent after-flame. It is NOT
designed for use in ARC flash or flash fire applications. When a flame
source is removed from the treated material, the material will self
extinguish within a given time frame. The treated material can melt and
drip and has a limited life span dependent on washing and what the
garment is exposed to.
