Lee Hale: I have seen class 0 gloves that have lasted 6-8 years if properly protected and used with the correct glove talc. I’ve also seen the “baby powder glove approach” that won’t make three tests. It’s all in the usage, proper storage and correct glove talc or glove liner. If your folks are using baby powder, the glove will not last very long.
Hugh Hoagland: Gloves are replaced when they fail a visual inspection, air test or electrical test. If there is anything that makes a worker suspect the glove is unfit for service, feel free to replace it but there is no annual replacement requirement. Many high voltage gloves will last for 5-8 years depending on use. Please use ASTM F496 and the manufacturer’s website for guidance.
