10-25 Manhole or Transformer Fire or Emergency
Any type of manhole or transformer fire or emergency.
Without Code: Code 1:
Code 2:
Code 3: Code 4:
Note:
Situation other than as described in Codes 1, 2, 3, or 4.
Fire has extended from a manhole, conduit, or transformer into a building.
Fire has blown one or more manhole covers, or smoke is issuing from a manhole under pressure.
Smoke is seeping from a manhole.
Fire or smoke condition from a transformer at any location, i.e., pole, vault, room, etc.
Utility Company will dispatch an emergency crew immediately upon receipt of a Code 1 or Code 4 signal.
1.2 Should conditions change after original report, a supplementary report shall be transmitted immediately to describe the existing conditions in accordance with the above code.
Units should be alert to the possibility that a manhole/transformer incident could have damaged the adjacent gas piping. If an odor of natural gas is encountered at these incidents, the dispatcher must be notified to request the immediate response of a utility’s gas crew in addition to their electric crew. Additionally, downed overhead primary and secondary wires have the potential to damage underground gas piping. All gas piping (plastic, steel, cast iron and copper) can be impacted by burning, arching or smoldering electric cables.
*ic calls utility unit stays on scene
During periods of multiple incidents within an area, the following actions may be authorized by the deputy chief in charge:
One or more units shall be relieved from response assignments and utilized as follows:
A. A member of the unit shall be left at the scene of each incident.
B. The officer and the chauffeur shall remain with the apparatus to perform surveillance of the incident locations.
**C. BATTALION CHIEFS SHALL PROVIDE FOR NECESSARY RELIEF OF UNITS OR MEMBERS.
D. Deputy Chiefs may authorize the use of messenger vans and spare cars for travel and shelter of members at incident locations.
TEST
Members should not pull covers off electrical manholes at manhole fires or if a manhole fire is in the area. It is the responsibility of utility crews to open manhole covers at these incidents.
(-At gas leak we can pull round sewer and round electric round electric you need IC and con ed. Sewer just IC )
-Note: This does not change Department policy of pulling electric manhole covers under certain circumstances at gas emergencies.
***Only round cover not rectangular covers
Underground transformers are not easily noticed since they are located in subsurface concrete structures. CON EDISON has stated that there are approximately 75,800 transformers citywide. The subsurface structures, known as transformer vaults, come in various sizes but a typical vault is approximately 12’ x 4’. These vaults are installed either in the street or the sidewalk below grade level.
- Vaults in the street sometimes have solid gratings since heavy vehicles may cause damage to the weaker slotted gratings. The gratings are usually rectangular in shape.
- The transformers convert primary voltage (27,000 Volts) to secondary voltage (120 Volts) for use by CON EDISON customers. Either of these voltages can cause fatal injury if not handled properly.
All transformers that are in the vaults contain dielectric oil, which acts as a coolant, in amounts ranging from 200 gallons to 600 gallons. The trade name for the newer oil that CON EDISON is presently using is SUN-OIL or MOBIL-X. This oil contains PCBs in the range of 10- 49 PPM and therefore is considered a Non-PCB Transformer. However, CON EDISON still has in use vault transformers that are considered PCB-CONTAMINATED TRANSFORMERS that contain 50-499 PPM of PCBs.
Note: The New York City Fire Department considers a transformer with any amount of PCBs as a PCB Transformer. Operate accordingly.
- The possibility of asbestos may also be present,
- The greatest hazard of course is the amount of electricity that is contained in these vaults.
Con Ed transformer vault.
- Members are not to enter these vaults until Con Edison has made their examination.(even if people inside)
2. 4 Con Edison will make the determination that the vault is safe for entry, if necessary, by F.D. personnel.
2. 5 F.D. personnel receiving this authorization will conduct a cursory search of the vault for victims.
ADD 1
TEST** (on chief off can call)
Chief Officer at the SCENE of an electrical emergency to telephone the Shift Manager at the Borough Electric Control Center.(not for substataion) This policy applies to situations where certain technical or response advice from Con Edison would assist the Incident Commander in making operational decisions OR WHERE conditions change to a degree that a PRIORITY CON EDISON RESPONSE IS WARRANTED. (code 1 or 4)
Some conditions that might require notification to the Con Edison Shift Managers are:
RESPONSE TO TRANSFORMER VAULT AND MANHOLE EMERGENCIES
3.1 Con Edison dispatches an Emergency Crew to a Signal 10-25, Code 1 or Code 4 incidents. The Emergency Crew’s time of arrival can vary, depending on availability of crews, i.e. work in progress and geographic location of the crews and the number of ongoing incidents. If an incident becomes more severe than originally stated, or if technical information is required, the Incident Commander can now telephone the Con Edison Shift Manager directly to request assistanceA dedicated FDNY telephone number installed at each of the regional control centers will be established for this purpose. (differant numbers for each bough)
RESPONSE TO SUBSTATION EMERGENCIES
4.1 At times, Con Edison substations may not be staffed during an FDNY response or the Substation Operator may not be available. In this situation, the I.C. should then contact the Substation Shift Manager at 212-460-3848.
Note: Con Edison substations do not fall under the jurisdiction of the Electric Control Center.
*TEST**
If Con Edison’s ETA is not satisfactory or if conditions worsen while waiting for the Emergency Crew, the I.C. shall call the respective Electric Control Center Shift Manager with an updated report and explain the need for a priority response. AN UPDATED PROGRESS REPORT MUST ALSO BE TRANSMITTED TO THE DISPATCHER.
5.3 If technical information is required, the I.C. shall call the Electric Control Center Shift Manager for advice and assistance.
*TEST
Notes:
1. Only a Chief Officer may call Con Edison from the scene.
**2. IF A SITUATION ESCALATES TO INVOLVE SEVERAL OCCUPANCIES OR IF THE CONDITION AFFECTS A LARGE AREA, THE I.C. SHOULD CONTACT OEM FOR ASSISTANCE.
3. This policy does not preclude the responsibility of the FDNY Incident Commander from transmitting the proper signal or progress reports via the Department Radio.(even call con ed still udate dispther)
4. Con Edison telephone numbers should be programmed into Battalion cellular phones.
5. Con Edison has cell phone numbers for each Battalion in the event they need to speak to the on-site Battalion Chief (Incident Commander).
