Do I need to test my gloves?

Yes, however it varies by class. For example Class 0 gloves, a common glove used with repairing EVs, must be tested by a blow test (either by manually blowing into the glove to identify any holes or leaks, or by using a Pneumatic Glove Tester. They should be tested before each use with a blow test and every (6) months thereafter and upon indications the insulating value is suspect. The OSHA Regulation 29 CFR 1910.137 states all insulating equipment must be inspected for any damage before each day’s use and immediately following any incident that can reasonably be suspected.
