8.0 GS
False
-All Fire Department units are to treat downed wires as live wires until an on scene utility company representative confirms that the wires have been de-energized. There is currently no safe way for FDNY personnel to move energized power lines, even if it presents a condition imminently dangerous to life.

with a wooden hook or rope?
8.0
Do not attempt to move wires with any hook or rope.
-• Do not place weighted objects on downed wires. This may cause the wire to make substantial contact with the ground and produce arcing and whipping as well as produce a voltage gradient in the immediate area.
Of the following which is incorrect, only one?
Immediately upon confirming that live electrical wires are down and are creating a situation that places human life in danger: do following?
A - Request response of Battalion Chief if not already assigned.
B- Responding Battalion Chief shall contact dispatcher indicating that life is in danger and request priority response and request forthwith power removal and priority response by utility company.
C- Isolate the area,Keep apparatus away. Overhead wires are supported by poles, which could possibly topple in a domino effect, thereby endangering members if they are within the area of possible pole collapse.

NOTES:
Check nearby buildings for heat at fuse box/electrical service entrance box. Utilize thermal imaging cameras as hand contact may result in electrocution if the box is energized.
T/F?
In situations involving live electrical wires which are down but do not present an imminent life hazard, the Department can only guard against the hazards of fallen wires by isolating the area, notifying the utility company and standing by until a utility company crew responds. It is the utility company that will correct the problem.
True 8.2 GS
In either situation involving live electrical wires which are down wheather do or dont present a imminent life hazzard Stretch line with fog nozzle. Use distance as a safety factor. Keep at least ____ feet away from any downed wire while operating this handline.?
page 8 GS
25 Feet.
Notes:
Do not open the house service. Heated wires may generate carbon monoxide gas in the service box, which can explode when the opening of a breaker creates a spark.
POWER STATION EMERGENCY/SUBSTATION EMERGENCY
Actions to be taken. which is incorrect . only one?
A-Place a priority call to the Fire Department dispatcher for power removal. Be sure to request that ALL electrical equipment at the station be deactivated and request the immediate on site response of a utility company representative.
B- All electrical equipment at the station/substation is to be considered energized until verification of power removal is made by the on site utility company personnel.
C-Under no circumstances are members to enter substation until arrival of power company representative.
D-Do not under any circumstances bring metal ladders or metal tools inside of gate of generating station. Do not enter fenced off areas without power company representative.
8.3 GS
C incorrect.
C-Unless human life is in jeopardy, do not enter substation until arrival of power company representative.
Note:
No ladders, metal or wood, should be supported by metal superstructures.
T/F?
Overheated fluorescent ballasts may leak PCB-contaminated oil. SCBA must be used while performing the above operations.
9.0 GS
True
Page 21
Presence of leaking asphalt material from a ballast is not necessarily an indication of a PCB leak. But if the liquid does not solidify after cooling it could be an indication that the capacitor fluid has leaked. This fluid could be the dielectric used in ballast’s manufactured prior to 1979 and could be a PCB liquid.
When a Fire Department unit is called to provide assistance with the removal of a disabled passenger from a wheelchair lift, the following precautions must be taken before any members are permitted to start removal operations:
22 GS
- The keyed switch at the bus driver’s seat that supplies power to the wheelchair lift, and the keyed switch located at the wheelchair lift that activates the lift must be in the off position and the key removed before operations commence.
- The officer shall insure that the wheelchair lift is secured, chocked, and stabilized to insure that the wheelchair lift will not move in the event of hydraulic or mechanical failure.
