MOS Reference: NFPA 2112 certified flame-resistant work shirt constructed from inherently FR-treated cotton blend fabric that self-extinguishes when removed from an ignition source. Arc-rated (ATPV 8.9 cal/cm2) for protection against electric arc flash hazards in HRC Category 2 environments. Relaxed fit allows layering and unrestricted movement. Two chest pockets with flap closures and button front. Fabric maintains FR properties through the life of the garment regardless of wash cycles. Essential for oil and gas, electrical utility, and welding operations where flash fire or arc flash exposure is a risk.
