- All overhead electric lines are to be considered as energized and life threatening until or unless it is positively confirmed that the proper authorities have identified and have deenergized them.
- All overhead ground lines that are discovered or become severed must be considered energized on both sides of the sever, and be treated accordingly.
- In general, equipment or machinery being moved or transported must maintain minimum clearances of 25 ft. to all power lines. If equipment or machinery must operate within 25 ft. of energized power lines, one of the following must occur before beginning work:
- The senior company employee on the site must positively confirm the voltage(s) of the line(s) involved and coordinate the following information with the Carter & Carter Safety and Health Manager to confirm the minimum clearances for the lines:
Line Voltages | Minimum Clearance |
---|---|
50 KV and less | 10 ft. |
51 KV to 200 KV | 15 ft. |
201 KV to 345 KV | 20 ft. |
346 KV to 500 KV | 25 ft. |
NOTE:
- In lieu of the above clearances, a distance of at least twice the length of the line insulator may be used, but never less than 10 ft.
- Equipment swing and/or boom restraints or alarms may be installed to physically limit or warn against proper clearance encroachment.
- If the operation of the project allows, the senior company employee on the site may contact the proper authorities and arrange to have the line(s) be deenergized, including physical grounds, for the duration of the operation.
- Arrangements are made with the proper authorities to have all such power line(s) effectively shielded during the construction operation.
- The senior company employee on the site is to designate a person to assist the equipment operator in observing and maintaining proper clearances in order to comply with the above.
- An adequate ground line or jumper shall be placed as needed in order to dissipate any induced voltage charge (static electricity) in equipment or materials being handled in the vicinity of transmitter towers or high voltage electric lines. In addition, combustible and flammable liquids are not allowed to be stored or transported through such areas.
