The VolCore Work Shirt, No. FRS-003, from Radians helps protect workers from short-term thermal hazards, including arc flash and flash fire. The work shirt is compliant with ASTM 1506, NFPA 2112, and NFPA 70E PPE CAT 2 industry-wide FR standards. According to the company, because the work shirt self-extinguishes and does not melt when exposed to flame, it dramatically reduces the severity of burn injuries. It is made with 7 oz. 100 percent cotton soft woven twill and provides comfort and mobility. The shirt is available in navy, gray, and khaki and sizes M-XL and tall sizes.
