1. Before opening any enclosure that may contain
energized circuit parts or equipment, every source
of power over 50 volts must be disconnected and
appropriate lockout/tagout procedures initiated.
2. After the enclosure is opened, a “qualified person
wearing suitable PPE must use appropriate test
equipment to test all exposed parts insuring that the
equipment is electrically safe. Special consideration
must be given to insure that all capacitors are
discharged and that all control power disconnected.
Until the testing is completes, OSHA considers the
equipment to be electrically unsafe.
There are only two exceptions to this requirment:
1. It will create a greater hazard to de-energize the
equipment typified by disconnecting ventilation to
hazardous areas, or alarm systems.
2. Access to energized equipment is required to
perform voltage, current, or other tests.
