| Post subject: | Arc Flash Rated Cut Resistant Gloves |
Looking for recommendations of a glove rated for both ANSI Cut 6 (or 7) and Arc Flash Category 2. Our current cut resistant gloves were a mitigating factor in an arc flash incident. My concern is that people make mistakes and someone could simply forget to change gloves before taking a measurement in a live bucket (especially people who have been in the trade for too long  )

I got mine from Grainger. They fit well and are comfortable. Opinions may vary as to whether or not they are fine for data collection but you're right, I wouldn't recommend them for live work. They don't provide tested, listed or labeled shock protection that I know of. |

Can you please provide a little more clarification since it sounds like you're wanting a pair of arc rated leather gloves (with a cut resistance rating) but then you say "taking measurements in a live bucket". First of all, where I come from the term "bucket" is associated with 600 volt rated MCCs which are normally energized at 480 volts. I'm assuming when you say "taking measurements" you're speaking of taking voltage and/or current readings with a DMM. If this is the case, then the Restricted Approach Boundary (RAB) is 12 inches/0.31 m for the voltage range of 151 to 750 VAC per NFPA 70E and CSA Z462 (since it looks like you're in Canada). Taking current reads may or may not but voltage readings using standard DMM probes will certainly place the hands well into the 12" RAB which will require shock protection of the hands. According to article 130.4(G) if the qualified person approaches or take conductive objects any closer than the RAB of an exposed energized part then he or that body part must be "insulated or guarded" from the exposed part. This is also reiterated in article 130.7(C)(7) specifically for the hands and arms. If this is also the case, then your electricians should be wearing rubber insulating gloves (min of class 00) with protectors rather than arc rated gloves, because the latter is only designed to protect against thermal energy and not electrical shock. That said, Youngstown Glove company has several types of leather protectors (to be worn over rubber gloves) and arc rated leather work gloves meeting the Category 2 (min 8 cal/cm2) APTV rating that also carries ANSI cut and puncture resistance. Several years ago we had an arc flash incident inside a 480V MCC where the worker's hands were completely inside the bucket and literally right next to the source of the arc flash, meaning well within the working distance of 18". While a LOT of mistakes were made by the electrician, he made one correct decision, that was to wear his class 0 rubber gloves with arc rated leather protections (36 cal/cm2) and a 40 cal arc flash suit and hood. Based on this one good choice he walked away with no injuries. Because these Youngstown protectors proved their worth during a real world arc flash I'm a HUGE proponent of their products. In any case here's the link to Youngstown Gloves website. https://ytgloves.com/ |
