How are Arc Flash thermographer’s gloves used?
Arc Flash Thermographer’s gloves are manufactured of an arc-rated fabric that has been tested according to ASTM F1959 to provide protection against the thermal incident energy of an Arc Flash. Like the Arc Flash garments that are used in this application, the fabric is arc-rated and flame resistant and provides some level of insulating protection against the thermal incident energy. Again, like the Arc Flash suits, they are assigned an arc rating to reflect the level of protection offered (either ATPV or EBT).
Arc Flash Gloves are NOT manufactured of rubber. As such, they do not provide shock protection against voltage. They should not be used within the Restricted Approach Boundary as defined by NFPA 70E where there is the risk of contact with voltage due to proximity to the energized circuit. Within this space, only rubber electrically insulating gloves should be used to protect the worker from accidental electric shock. The NFPA 70E Standard requires that a shock risk assessment be performed and documented.
Further, Arc Flash Thermographer’s Gloves are not to be used as an alternative to leather protectors for rubber insulating gloves. Leather protectors are worn over rubber insulating gloves to protect the rubber gloves from physical damage. Even the smallest puncture can provide an avenue for the voltage to penetrate the glove and contact the worker. Thermographer’s Gloves are manufactured of a woven fabric, which will provide limited protection from mechanical hazards. Leather is a dense material that resists and decreases the likelihood of puncture.
Arc Flash Thermographer’s Gloves are promoted to workers working within the Arc Flash Protection Boundary.
Arc Flash Gloves available by Oberon include 25, 40, 65 and 100 calorie versions.
