YOU ARRIVE AS THE 1St DUE ENGINE AT A FIRE IN A CON EDISON ELECTRICAL FACILITY, YOU ORDER YOUR MEN TO STRETCH 3 1/2” HOSE TO AN AKRON NEW YORKER AND BEGIN APPLYING WATER TO THE FIRE, DID YOU OPERATE CORRECTLY?

A

NO

++The decision to apply water streams to electrical components at Con Edison facilities will not be undertaken by first responding units. This decision can only be made by a Chief Officer above the rank of Deputy Chief (or a Deputy Chief operating as Car 421 or Car 422) in consultation with the Con Edison White Hat at the scene.++

26
Q

WHAT IS THE PRIMARY MEANS OF APPLYING WATER TO ENERGIZED ELECTRICAL COMPONENTS OF A CON EDISION ELECTRICAL FACILITY?

A

TOWER LADDER

++5.4 The primary means of applying water to energized electrical components is through the use of a Tower Ladder. When using a Tower Ladder the following procedure shall be adhered to:

  1. 4.1 Clear all sediment from the water supply by flushing the hydrant thoroughly before connecting to the pumper.
  2. 4.2 The type of tip to be used on the Tower Ladder is dependent on the ability of the stream to reach the target area. All Tower Ladder Companies are equipped with stacked tips to supply a solid stream and the Akron Turbomaster Nozzle which has an adjustable stream pattern from straight to fog position.
  3. 4.3 The waterway of the Tower Ladder must then be flushed away from the point of operation and all electrical components for several minutes until the water runs clear.
  4. 4.4 Attach the selected tip to the basket mounted stang. If using the Akron Turbomaster Nozzle, set the desired stream pattern. The basket mounted stang is then set to the desired angle and locked in place.
  5. 4.5 The safe operating position for the apparatus will be determined in conjunction with Con Edison personnel. Once determined, all members are removed from the basket and 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.

5.4.6 If the stream is not reaching the intended target area then the water supply must be shut down at the pumper and the position of the basket or the angle and/or pattern of the stream must be adjusted. Once the basket is repositioned, and all members are off the apparatus, water is again supplied to the Tower Ladder. NOTE: When the stream is re-positioned, ensure that the minimum safe operating distance for the type of stream employed is maintained.

27
Q

TRUE/FALSE

AT FIRES IN CON EDISON ELECTRICAL PLANTS IT IS ALLOWABLE TO USE THE AQUASTREAM NOZZLE.

A

FALSE

++NOTE: The Aquastream Master Stream Nozzle carried by all Aerial Ladder and Engine Companies is factory pre-set to a fog stream pattern of 130 degrees. This nozzle shall not be used because it does not provide enough stream penetration to allow for maintaining safe operating distances.++

28
Q

TRUE/FALSE

FDNY MEMBERS SHALL NOT ENTER A CON ED FACILITY WITHOUT A CON ED ESCORT AND APPROVAL OF INCIDENT COMMANDER.

A

TRUE

++FDNY members shall never enter inside the Con Edison facility property line unless escorted by qualified Con Edison station personnel and with the approval by the Incident Commander.++

29
Q

WHO CONFIRMS THAT ALL FDNY EQUIPMENT PLACED INSIDE THE PROPERTY LINE AT A CON ED FACILITY IS CONNECTED TO THE FACILITY’S GROUND GRID?

A

CON ED PERSONNEL

++Con Edison personnel shall confirm that all FDNY equipment inside the Con Edison property line is connected to the facility’s station ground grid.++

30
Q

TRUE/FALSE

SALT WATER CAN BE USED WHEN APPLYING WATER TO ELECTRICAL COMPONENTS AT CON ED FACILITIES.

A

FALSE

++Only fresh water shall be used for applying water streams on live electrical components. Salt water shall never be used.++

31
Q

TRUE/FALSE

FOAM CAN BE USED IN CON FACILITIES.

A

FALSE

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

32
Q

WHAT IS THE DESIRED FOAM PATTERN WHEN APPLYING WATER TO CON ED FACILITIES?

A

30 DEGREE

++Fog streams are poor conductors of electricity and are therefore the preferred water stream pattern. The desired fog pattern mode is a 30 degree or greater fog stream.++
