Q: Would retesting be needed if I don't use the electrical safety gloves very often and visually see no damage?
A: Yes. Retesting is still needed to help verify the integrity of the material and to ensure electrical safety is maintained for the user.
Q: Can I just use the rubber glove only, and not buy the leather part?
A: A leather protective glove should always be worn over rubber insulating gloves to provide the needed mechanical protection against cuts, abrasions and punctures. However there are some exceptions highlighted in OSHA’s electrical protective equipment standard 1910.137 (c ) 2 (vii) (A) – (C). If the voltage is 250 volts AC, or 375 volts DC, protector gloves need not be used with Class 00 gloves, under limited-use conditions, when small equipment and parts manipulation necessitate unusually high finger dexterity. It also states that protectors need not be used with Class 0 gloves under the same limited-use conditions. Persons inspecting rubber insulating gloves used without protectors need to take extra care when visually examining them. Employees using rubber insulating gloves under these conditions need to take additional caution when handling sharp objects that could nick or cut the glove. Any other class of gloves may be used without protector gloves, under the same limited-use conditions if the class of gloves is one class higher than that required for the voltage involved. Rubber insulating gloves that have been used without protector gloves may not be reused until they have been retested.
Q: How do I size my leather protector that is worn over my rubber insulating glove?
A: It is suggested to select the same size leather protector as the rubber insulating glove. For length, the insulating glove cuff must be longer than the leather protector glove and the distance is specified by class. Use the following guidelines:
Q: Where can I get my gloves retested?
A: Grainger offers glove retesting and other environmental, health and safety services, or utilize a testing laboratory accredited by North American Independent Laboratories (NAIL) for Protective Equipment Testing.
Q: If I find a hole, can I just "patch it," like a tire inner tube?
A: Per 1910.137(c)(2)(x)(D), “Rubber insulating gloves and sleeves with minor physical defects, such as small cuts, tears, or punctures, may be repaired by the application of a compatible patch. Also, rubber insulating gloves and sleeves with minor surface blemishes may be repaired with a compatible liquid compound. The repaired area shall have electrical and physical properties equal to those of the surrounding material. Repairs to gloves are permitted only in the area between the wrist and the reinforced edge of the opening.” Repaired insulating equipment must be retested before it can be used.
