Heavy-duty protection in lightweight package
Two synthetic fabrics are combined in the ArcSafe™ Suppression Blanket from Workrite (Your Uniform for Life Company). Both space-age fabrics are aramid-fiber types. The inner layer is Kevlar® and the outer is NOMEX® III.
Kevlar is the same aramid fiber used in combat helmets and body armor. Flame-resistant NOMEX III is used as the cover to protect the Kevlar core from ultraviolet degradation.
Because the blankets consist of thin layers, ArcSafe blankets offer unrivaled portability and are extremely easy to maneuver in confined spaces. They weigh only 1/5 pound per square foot ( 5/8 kg. per m2 ).
Applications and conforming to OSHA law
When draped or loosely wrapped over a defective cable or splice, ArcSafe provides a protective shield for exposed workers. Velcro® straps sewn on the back help keep ArcSafe where positioned.
ArcSafe blankets meet or exceed OSHA requirements for manhole protection.
Beginning in 1991, OSHA mandates that if cables in manholes appear defective . . .
". . . and cannot be de-energized due to service load conditions, employees may enter the manhole provided they are protected from the possible effects of a failure by shields or other devices that are capable of containing the adverse effects of a fault in the joint." [29 CFR Part 1910.269(t)(7)]

Tested successfully at 42,000 amps fault current
ArcSafe was subjected to fault-current testing at Chance laboratories. ArcSafe was placed over a small section of 2/0 copper cable that was faulted to ground, simulating a cable or splice failure. The maximum fault current generated was 42,432 amps for a duration of 13 cycles.
Other than black deposits, ArcSafe experienced no damage and provided total fault-blast containment.
Kevlar® and NOMEX® are DuPont registered trademarks for its aramid fibers. Only DuPont makes Kevlar and NOMEX.
Warning: The ArcSafe Suppression Blanket has been developed by leading industrial and safety engineers, and Workrite believes it to be the best available for its intended purpose. However, explosions and blasts due to electrical faulting may be erratic and unpredictable, and we do not claim that ArcSafe offers total protection. It improves the chances of a worker's survivability in a life-threatening incident. In addition, ArcSafe is NOT classified as "Electrically Insulated" and must NEVER be used as such. Before using this or any protective product, please avail yourself of all information concerning its use.
