Qualified Persons

When a qualified person is working close to overhead lines, whether in an elevated position or on the ground, the person must stay at the distance from exposed energized parts shown in Table S-5. Furthermore, such person must also keep any conductive object lacking an approved insulating handle at the distance from exposed energized parts shown in Table S-5.

Exceptions to Table S-5 Distances

The only exceptions to the distances outlined in Table S-5 are as follows:

• The person is insulated from the energized part (by gloves, with sleeves if necessary, rated for the voltage involved) or
• The energized part is insulated both from all other conductive objects at a different potential and from the person, or
• The person is insulated from all conductive objects at a potential different from that of the energized part.

Interlocks

Only a qualified person may defeat an electrical safety interlock, and then only temporarily while he or she is working on the equipment. The interlock system must be returned to its operable condition when this work is completed.
