Question 7

What is the primary means of applying water to energized electrical components?

Answer 7

Tower ladder
Clear all sediment from the water supply by flushing the hydrants thoroughly before connecting to the pumper. The type of tip to be used on the tower ladder is dependent on the ability of the stream to reach the target area. Examples :stack tips to supply a solid stream and the akon turbo master nozzle which has been adjustable stream pattern from straight to fog position. The waterway of the tower ladder mustang be flushed away from the point of operation and all electrical components for several minutes until the water runs clear.

Question 8

Is it okay to have members in the tower that a basket while applying streams to electrical components?

Answer 8

All members are removed from the basket in the basket is then raised to operating position. All members are then removed from the apparatus. The stream will then be applied to the target area.

Question 9

If the stream is not reaching the intended target area where do you shut down the water supply?

Answer 9

At the pumper. Then the position of the basket or angle shall be adjusted. Once the basket is repositioned, and all members are off the apparatus water is against applied to the tower ladder. Note: when the stream is repositioned, in sure that the minimum safe operating distance for the type of stream employed is maintained.

Question 10

If the tower ladder is no good can we consider engine deck gone, latter pipe, or the Akron New Yorker?

Answer 10

Yes. Aqua stream Master nozzles carried by all engine and ladder companies is factory preset to a fog at 130°. Don’t use this because it doesn’t allow enough stream penetration to allow for maintaining safe distances.

Question 11

If the shit is hitting the fan can we enter a con Ed facility without approval of con Ed white hat?

Answer 11

Entry of members or any apparatus with in con ed facility shall only be with approval of con Ed white hat with an escort. Follow directions of white hat while inside facilities. FDNY members shall never enter inside the con Edison facility property line unless escorted by qualified con Edison station personnel and with the approval of the incident commander

Question 12

True or false
Confirm that all con ed equipment inside the con Ed property line is connected to the facilities station ground prior to applying water.

Answer 12

False
Confirm all FDNY equipment inside con Ed proper property line is connected to the facilities station ground prior to applying water. Con Edison personnel shall confirm this

Question 13

True or false

Either freshwater or salt water can be used for apply water streams on live electrical components.

Answer 13

False.

Only freshwater shall be used for applying water streams on live electrical components. Saltwater shall never be used.

Question 14

Is it safe to add foam while applying streams to electrical equipment?

Answer 14

No additives including any type of foam shall be used. Additives increase the electrical conductive any of the water.

Question 15

Fog streams are poor conductors of electricity and are there for the preferred water stream pattern. The desired fog pattern mode is a ___or greater fog stream.

Answer 15

30° or greater

Question 16

Fog streams can greatly be affected by wind conditions and may not reach the target area from a distance of 15 or 25 feet. In these situations what do you do?

Answer 16

A straight stream utilizing the fog tip or a solid stream shall be used and the standoff distances is increased

Question 17

True or false

The possibility of runoff water from a con Edison facility being charged with electrical current is extremely likely.

Answer 17

False
Is extremely remote. All con Edison facilities have Station grounding mats installed that would absorb any stray electrical currents and prevent pools of water outside the facility from being charged. However, avoid low spots when positioning apparatus and appliances. Member should also avoid water runoff.

Question 18

True or false
FDNY dispatchers will not give a specific address for a con Edison generating facility to responding units, but will use a more generic term e.g. con Edison victory Boulevard

Answer 18

True
The battalion chief can choose a rendezvous muster site placement of identifying decal. The decal is a larger version of an official far department shoulder patch with a con Edison white helmet and FDNY chiefs helmet display there
