As infrastructure ages, workers across the country are working tirelessly to keep the lights running. Unfortunately, many times this requires exposure to dangerous, and unpredictable cramped, confined, and underground spaces. As a result, NATIONAL SAFETY APPAREL’s research and development team has designed a safety product specifically for these conditions: a high-tech suppression blanket to protect workers from arc blasts in underground vaults, switchyards, tunnels, and any other confined space.

National Safety Apparel spends a significant amount of time and energy on design and testing to ensure the safety of the workers, and this product is no exception.  The ArcGuard Blanket is one of the few arc suppression blankets available today that has been tested and rated per ASTM F2676.

The blanket is designed to be attached to fixed points near the arc flash hazard area to redirect the release of energy that may occur. NSA offers high-strength Kevlar® webbing straps to be used with the blanket.

The blanket has been tested according to ASTM F2676, and meets OHSA 1910.269(T)(7) and NFPA 70E-2012 standards. Its maximum arc current Imax rating is 25 kA, and it has a breakopen threshold performance equal to 362 kA*cycles.
