| Post subject: | Voltage Measurement & Rubber Insulated Gloves |
Do you wear rubber insulating gloves when voltage testing on 240vac and 120vac? Standard practice has been to use leather gloves only at our site. The task table in 70E table 130.7(C)(9) indicates that rubber insulated gloves are are necessary. When I read 130.2(C) I do not think that they are necessary because no body part would cross the RAB. What are your opinions. |

Working On Live Parts In the definitions "Working On (energized electrical conductors or circuit parts). Coming in contact with energized electrical conductors or circuit parts with the hands, feet, or other body parts, with tools, probes, or with test equipment, regardless of the personal protective equipment a person is wearing. There are two categories of “working onâ€: Diagnostic (testing) is taking readings or measurements of electrical equipment with approved test equipment that does not require making any physical change to the equipment; repair is any physical alteration of electrical equipment (such as making or tightening connections, removing or replacing components, etc.)." Some of us old timers have used the phrase "Testing is Touching". Probes fail. Arcs happen in meters and the arc itself is conductive. People get shocked on 120V and slam their hand into 480V supplies in some locations. The DOE had a fatality in which someone was testing 42V control wires, got a shock and hit a 480V terminal block with their hands. The block arced and ignited their HRC 0 shirt killing the worker. Habits are the KEY. Just wearing rubber insulating gloves, saves more lives that just about anything we can do. The standard is very clear on this. |
