Electrical gloves should be inspected for damage before each day’s use and immediately following any incident that can reasonably be suspected of having caused damage. If during the inspection any of the following defects are found the gloves must be removed from service: holes, tears, punctures, cuts, ozone cutting, ozone checking, embedded foreign objects, swelling, softening, hardening, or becoming sticky or inelastic. As part of this daily inspection an air test should be conducted. The test method is described in American Society for Testing and Materials (ASTM) F 496, Specification for In-Service Care of Insulating Gloves and Sleeves. Basically, the glove is filled with air, either manually or by an inflator, and then checked for leakage. The leak is detected by either listening for escaping air or holding the glove against the tester’s cheek to feel air releasing. Here’s the part most users don’t do – the procedure should then be repeated with the glove turned inside out. Beyond the daily inspection, an electrical test will be conducted every six months to reliably indicate whether the electrical gloves can withstand the approved voltages. The test procedure to be used is ASTM D 120-87, Specification for Rubber Insulating Gloves. This test method must be performed by a testing laboratory. If the equipment passes the electrical testing, it is very common for the testing lab to mark the gloves certifying their use for another six months. Hint: when you purchase your electrical gloves, purchase two pairs. The first pair of gloves should be used from January thru June and the second pair from July thru December. It’s also a good idea when you place your order to order two different colors (or more). This will allow you to visually check valid glove use very quickly. For example, black gloves are used from January thru June and 0range gloves from July thru December.
