I was looking for some advise on gloves. We are working in a lab environment were handling heavy electrical work is not typical. More probing. So I am looking for the best grip as compared to rough electrician work. We were looking into getting the class 0 Salisbury gloves 1. Any difference on synthetic versus rubber ? 2. Any color easier to identify a glove defect or other advantage ? 3. Is goat skin better to work with then cow hide ? |

First, you have to identify what's your danger (ArcFlash or Electrical Shock)? ArcFlash, use a pair of Youngstown gloves goat skin HRC3 or Oberon Thermographer Gloves. https://www.ytgloves.com/products.asp?productId=301&categoryId=44&subCategoryId=0&subCategory2Id=0 http://www.oberoncompany.com/ourproducts2.php?cate=6 Electrical Shock, use a pair of Salisbury, Marigold, Novax, Magid. Question, why you want to use Class 0 (1000V)? http://www.novax-intl.com/products_gloves.php http://www.marigoldindustrial.com/ http://www.magidglove.com/ |

I'm going to bet your lab environment is a lot like mine. You are looking at class 0 gloves because NFPA 70E and OSHA require them for voltage >50V and you don't have an arc flash hazard because all your equipment is fed either cord & plug or from a 208Y120 circuit breaker panel down stream from a 125kva transformer. Some of the product we test is 3000v but fed from a micro amp source. A lot of the work require fine manual dexterity which you will not get wearing rubber gloves AND the protectors. NFPA 70E allows for just using the rubber gloves. Main thing is to get the fit right. Our lab doesn't allow glove dust & if you want to be able to take off the gloves repeatedly you will need liners. Gloves have to be sized for that. For testing, get a glove inflator. Doing the manual inflation test by fold the cuff and spinning doesn't work all that well for micro pricks from test probes and component leads |

Below 300 V, 70E says "avoid contact" but does not specify what that is. Some folks are interpreting this to mean insulated tools. If this were not so then all the 70E sections talking about insulated tools really have no practical purpose. |

If I look at table 130.7(c)(15)(a) there is a column for "rubber insulating gloves" and another for "insulated and insulating hand tools". From looking over the 8 scenarios provided in the category of <240 volts, it certainly seems the intent is to require the use of rubber insulating gloves (and tools) when you are putting your hands near live unprotected parts, which would include tasks such as voltage testing. The tasks that do not require the insulated gloves all either have some sort of assumed distance between the person's hands and the live parts, or covers on. For example you can remove a bolted cover to expose live wires with no gloves, but as soon as you need to work on the live wires, or do voltage testing, then you need the gloves on. Agree or disagree? |
