OSHA InterpretationI use OSHA's interpretation letter dated June 22, 1998 which can be found at
http://www.osha.gov. An exerpt:
Whether an employee needs to wear rubber insulating gloves while working with test equipment on energized circuits will depend on several factors including:
1. Whether the probes are designed so that the employee's hand can slip off the end of the insulated handle; and
2. Whether there are other exposed energized parts that the employee's hand might contact during testing.
If either of these conditions are present, the use of rubber insulating gloves or other electrical protective equipment would be warranted.
The letter also mentions 240 volt testing. This is one of those items that company policy should address. And we all know that everything will be great without gloves until someone gets hurt!
