What is the correct procedure for testing the integrity of lineman’s gloves, and why is this an important thing to do?
What will be an ideal response?
These gloves must be class "00" rubber insulating gloves, rated at 1000-volts. The condition of the gloves must be checked before each use. Make sure there are no tears or signs of wear. Electrons are very small can enter through the smallest of holes. To check the integrity of the gloves, blow enough air into each one so they balloon out. Then fold the open end over to seal the air in. Continue to slowly fold that end of the glove toward the fingers. This will compress the air. If the glove continues to balloon as the air is compressed, it has no leaks. If any air leaks out, the glove should be discarded.
