| Electric Utility Control During Structural Firefighting |
|
| Structure fires involve a risk of electrical contact for firefighters as well as building occupants. Coordinating with Duke Energy and following the tips below can help decrease this risk. |

|
| Coordinate with Duke Energy |
| Structural firefighting operations place firefighters in direct proximity to electric power lines and wiring that may be compromised by fire conditions or by the fire suppression effort itself. These facilities may pose hazards to a structure’s occupants as well as to you and your team. |
| When responding to a structure fire, remember that utility personnel are the experts in utility control. Duke Energy should be asked to respond to every structure fire. Once on the scene, utility personnel should be incorporated into the command structure. |
| Protect Yourself and Building Occupants |
| 1. |
Identify the location of overhead power lines, service drop wires and electrical panels during your 360-degree size-up. When evacuating occupants, direct them safely away from compromised utility lines. |
|
| 2. |
During operations, continuously communicate the status of electric service to operating crews and your dispatch center. |
|
| 3. |
Work with Duke Energy personnel to coordinate the safe control of electric utilities. |
|
| 4. |
Be aware that fire conditions may cause energized power lines to sag or disconnect from their structure and drop to the ground. |
|
| 5. |
Be alert for conductive objects when using aluminum ladders around structures. Fire may compromise electric wiring inside walls, energizing metal awnings and siding. |
|
| 6. |
Even after the electricity has been shut off, a backup generator may be in place and begin to operate. Treat all wires outside the structure as potentially energized and stay away until Duke Energy personnel inform you the lines are de-energized and grounded. |
|
| 7. |
When water must be used to protect exposures, use a modified hose stream of 30-degree fog at 100 psi. Direct the stream away from energized lines and other energized objects. |
|
| 8. |
Ensure that all personnel, ladders and aerial equipment remain at least 20 feet away from overhead power lines. Remember that higher voltages require greater distances. |
|
| What NOT to Do |
| • |
Do NOT park firefighting apparatus or other vehicles under power lines. |
|
| • |
Do NOT stand on the ground when operating aerial equipment in the vicinity of power lines. |
|
| • |
Do NOT cut electric lines, even if you believe that they have been de-energized. |
|
| • |
Do NOT move downed electric wires. |
|
| • |
Do NOT disconnect the service wiring on a structure or pull the electric meter out of its socket. |
|
| • |
Do NOT enter utility vaults, enclosures or switching cabinets. |
|
| • |
Do NOT enter a Duke Energy substation unless directed to do so by a utility representative. Do not spray water or foam inside a substation. |
