National Safety Apparel has designed a high-tech suppression blanket to protect workers from arc blasts in underground vaults, switchyards, tunnels and any other confined space. The ArcGuard Blanket™ has been tested and rated per ASTM F2676. It is designed to be attached to fixed points near the arc flash hazard area to redirect the release of energy that may occur.
