1. In order to operate effectively, it is necessary to have a working knowledge of the physical properties of underground and under river transit facilities. Which point below is not correct regarding under river tubes and tunnels? (2.2)
A. Tunnel is a general term which describes a below-grade passageway. There are numerous underground tunnels between transit stations throughout the NYCT system. The Transit Authority also refers to its 14 sets of under river crossings as tunnels.
B. Most under river tunnels actually consist of two separate structures referred to as tubes. Under river tubes are constructed of brick, concrete, or tubular cast iron. Some cast iron tubes are lined with concrete and the walls are between 2 and 2½ feet thick.
C. Most tubes have no access to the adjacent tube throughout the underwater areas. You cannot ride a train halfway across the river, get out of the train and cross over to the adjoining tube.
D. Under river tubes are wider than underground tunnels. There is ample space between the train and the tube. In the event of a collision or an explosion, it will be very easy to access the side of the train from the exterior.

1. D

 Under river tubes are narrower than underground tunnels. There is very little space between the train and the tube. In the event of a collision or an explosion, it may be impossible to obtain access to the side of the train from the exterior.

3. The NYCT Guidebook for Emergency exits distinguishes between two types of emergency exits. Standard exits are emergency exits where the doors of the exits are flush with the sidewalk while upright exits have vertical doors and are located in the side of a structure. To open these emergency exit doors the subway triangle key and the billy bar can be used. Which point about these tools is incorrect? (2.5)
A. Both the standard and the upright emergency exits can be opened using the subway emergency tool, the triangle key.
B. The ring around the lock is a security device designed to prevent the opening of exit doors by unauthorized persons.
C. The Billy Bar Tool has two points that fit into the holes in the ring, preventing its movement, allowing the locking device to be opened.
D. The Billy Bar Tool aids in opening the doors more quickly and easily. Without the use of the Billy Bar Tool the subway emergency exit doors will not open.

3. D

Although not essential, the Billy Bar aids in opening the doors more quickly and easily.

7. The Emergency Evacuation Device (EED) was designed by the New York City Transit Authority and is provided for FDNY use. EED’s are located throughout the Transit Authority’s subway system. Which point below is the only incorrect point about the EED? (AUC 207 Add. 11)
A. The EED is a yellow, 7-foot long device with steps on the front and a flat surface on the backside. A non-skid surface is applied to both sides. When positioned against the side or end doors of a subway car the EED will reach the roadbed at approximately a 70° angle.
B. At underground and grade level stations, the EED is located at the first Blue Light location north of the northbound platform (typically within 100 feet of the platform end). At elevated stations, the EED will be located in the area of all token booths. An EED is located at the base of the emergency exit, on one side of each under river tunnel.
C. Metal mounting brackets are provided at each location and are secured with a corrosion resistant padlock. If a key cannot be obtained, the locks can be forced using conventional forcible entry methods.
D. EED’s can be used as a ladder from the bench wall or a train to track level, or as a bridge between adjacent subway cars. With the flat side up they can be used to move passengers from one train to another. When this is done, ropes or hooks should be used as guides.

8. L100 is operating at a train derailment in an under river tube that connects Manhattan and Queens. There are no reported injuries however, a determination has been made by the IC that the passengers must be walked out of the tube to the nearest station on the Queens side which is about 1000’ away. The power has been removed and the passengers will walk on the track bed. Members of L-100 would be most correct to take which action below? (2.2.1)
A. Have the passengers walk between the rails since this area is flat with no obstructions. Also be aware that the 3rd rail always runs along the right side of the train.
B. Have the passengers walk between the rails but use caution since there is a drainage trough which could create a tripping hazard. Also be aware that the 3rd rail always runs along the left side of the train.
C. Have the passengers walk in the area outside of the rails on the opposite side of the 3rd rail. Also be aware that the 3rd rail alternates sides as it goes through the tube/tunnel.
D. Have the passengers walk in either the area between the rails or outside of the rails whichever is easiest for the passengers. Also be aware that the 3rd rail alternates sides as it goes through the tube/tunnel.

8. C

Typical under river NYCT subway tube. Note the following features: Cylindrical tube shape, drainage trough between running rails, benchwall, dry chemical extinguisher, blue light phone and standpipe. Also note that it would be unsafe to walk between the running rails due to the drainage trough. Personnel and evacuating passengers should walk in the area outside the rails, opposite to the third rail; be aware that the 3rd rail alternates sides as it goes through the

10. Lt. Smith was discussing communications with his members during an afternoon drill and was talking about using the Post Radio at under river rail operations. Which point made by Lt. Smith was not entirely correct? (2.9.6)
A. When the Post Radio is going to be used within the subway system NYC Transit must be notified.
B. The increased wattage of the Post Radio may increase our operating range within the subway system.
C. The Post Radio can be used in any area of the subway system since it is electrically shielded and won’t cause electrical interference.
D. Post Radios may be useful to communicate above ground from one side of the river to the other side of the river.

10. C

2.9.6 Post Radio
Do not use Post Radios in immediate vicinity of signals, communications equipment or train operator cabs, due to the possibility of electrical interference. Notify NYCT
when Post Radios are in use within the subway system. The increased wattage of these Post Radios may increase our operating range. Post Radios may be useful to communicate above ground from one side of the river to the other.

11

11. The first consideration on arrival at an operation involving electrified track will be a determination of whether the power is to remain on or be turned off. When power removal is required it shall be accomplished at all times via apparatus radio through our own Dispatcher. The only exception to this is when there is immediate danger and power must be shutoff to save lives in imminent danger. In this case the nearest power removal box shall be used and the Desk Superintendent shall immediately be notified via the emergency telephone that power is to remain off. Members operating in the various rail transit systems in NYC would know which choice below about electrical power is correct? (AUC 207 Add. 9 2.1, 2.8, Add. 11 Section 7)
A. Overhead catenary wires deliver 10,000 to 30,000 volts of AC power.
B. Standing trains can be supplied with power via a cable that will deliver 360 volts of AC Power.
C. The Air Train is powered by a third rail power system which delivers 750 volts DC Power.
D. In under river tubes 2,000 volt electrical lines may run throughout the tube at the ceiling level.
E. The 3rd rail in the NYC Subway system delivers 660 volts of AC Power.

11. C

2.1 CATENARY WIRES – Overhead electrical wires delivering approximately 12,000 (12KV) volts of alternating current (AC).

2.8 480 VOLT STAND-BY POWER – Electrical power supplied to a standing train via a cable supplying 480 volts of AC power to operate the refrigeration, lighting, air conditioning, and any other incidental electrical equipment between runs.

9.1.1 Electrical Power
Third rails in the affected tube and in adjacent tubes may be live. In addition, 1,000 volt lines may run throughout the tubes at ceiling level.

A track with a Dual Power System may be supplied simultaneously by an Overhead Catenary Line, usually
11,000 Volts AC current and also a ground level 3rd Rail, usually 660 Volts DC current.

15. When responding to incidents in under river tubes and nearby stations it is important for units to evaluate all information upon arrival so they can distinguish between a routine incident and a more serious incident. If a potentially serious incident is suspected members should assume a defensive position while performing a thorough size up and hazard assessment. All of the following points below indicate a serious event except which one? (3.1)
A. When the dispatcher receives information from a single source from either side of the tube.
B. Reports indicating heavy smoke or fire, an explosion, or a chemical release.
C. One or more trains that are stuck in the tube.
D. Unusual smoke or vapors in the station.
E. Reports of numerous sick or overcome passengers.

15. A

Indications of a serious incident:
 Reports indicating heavy smoke or fire, an explosion, or a chemical release.
 Dispatcher receives information from SEVERAL sources, possibly from both sides of tube.
 One or more trains are stuck in the tube.
 Reports of numerous sick or overcome passengers.

16. BC Question - The first arriving Battalion Chief at an incident in an under river tube has to make many critical decisions that can affect the safety of operating members and evacuating civilians. At a recent incident in an under river tube the 1st arriving Battalion Chief took the following actions and was incorrect in which one?
A. The Chief special called a Battalion Chief, one Engine Co., one Ladder Co. and a Haz Mat Technician Engine to stage at the stations and emergency exits nearest to the under river tube.
B. Since SOC resources at this incident were stretched thin, the Chief only used SOC units to assist self-evacuating passengers, to perform structural assessment, and to use their meters to monitor for radiation and chemicals.
C. The Chief consulted with the Transit Authority Liaison and took into consideration that the Transit Authority will be attempting to move any operable trains out of the affected tube in the early stages of the operations.
D. When there were indications that there were civilians on the tracks power removal was immediately requested in the affected tube. Members were also notified to operate as if the power was still on.

16. B
 At an incident like this, SOC resources may be stretched thin and should be used only as necessary for monitoring, structural assessment, and technical rescue.
If use of the SOC Rebreather System is being considered, request it as soon as possible, due to the time it takes to put into operation.

17

17. BC Question - A new Battalion Chief was operating at an incident where a train stalled and was stuck in an under river tube. The stalled train was near a crossover at an emergency exit. Prior to the fire departments arrival about 20 passengers self-evacuated the train and were standing on the live tracks of the adjoining tube. When the 1st due Ladder Co. arrived they quickly got the passengers safely back on the stalled train, notified the Battalion Chief that the passengers were able to be safely sheltered in place on the stalled train, and remained on the stalled train with the passengers. Power was requested and confirmed removed to the tracks that the stalled train was on and also to the tracks in the adjoining tube. The Chief ordered power restored to the adjoining tube, and told the conductor and train operator it was safe to proceed into the adjoining tube. After removing the 20 passengers with the rescue train, a complete search of the adjoining tube was conducted. Do you Agree or Disagree with the Chief’s actions at this incident? (4.5)
A. Agree or D. Disagree

17. D

 A decision will need to be made regarding the power status of the adjacent tube, which may be accessible via the crossover at the emergency exit. If passengers and/or firefighters are in the adjacent tube, request power removal. AFTER the adjacent tube is searched and secured, the IC may request a “Rescue Train” be routed through this tube, in which case the power would have to be restored.

18

18. The Incident Commander at an under river tube incident may authorize limited entry into the tube for reconnaissance. This can provide the Incident Commander with invaluable first-hand information about incident conditions. Which unit(s) listed below would be a logical choice to use as a reconnaissance unit? More than one correct. (6.1.1)
A. An Engine Co. standing fast at the incident.
B. The 2nd due Ladder Co.
C. The Hazardous Materials Unit.
D. A Rescue Company.
E. A Squad Company.

18. D, E

6.1 Reconnaissance
Depending on the results of the size-up and hazard assessment, the IC may authorize limited entry into the tube for reconnaissance (recon). This would provide us with invaluable first hand information about incident conditions.
6.1.1 A Rescue or Squad Company would be a logical choice as a recon unit for the following reasons:
 Metering capability
 1 hour SCBA cylinders
 Knowledge of structural issues

19

19. One important aspect to a successful operation at an incident in an under river tube is ventilation. Controlled and coordinated ventilation will increase the chances of survival for passengers and enable firefighters to operate more safely and efficiently. Which point listed below about ventilation is not correct? (4.6)
A. It is critical to contact the trainmaster to determine fan status, and to obtain available information about smoke conditions in the tube, especially in the vicinity of any stalled trains.
B. Be cautious when changing the ventilation actions that were initiated by the Trainmaster. These actions may have been based on specific information that we are not aware of. Also, there may be unintended consequences of such a change.
C. If possible, exhaust smoke and other contaminants toward evacuating passengers by using the fans on one side in the supply mode while using fans on the opposite end in the exhaust mode. This will ensure fresh a fresh air supply is being pushed toward the evacuating passengers.
D. Evacuation should take place away from any fan operated in the exhaust mode. This may not be possible at an incident in an under river tunnel. If a fire or explosion occurs in the middle of a train, passengers may self-evacuate in both directions.

19. C

 If possible, exhaust smoke and other contaminants away from evacuating passengers by using the fans on one side in the supply mode while using fans on the opposite end in the exhaust mode.

20

20. BC Question - You are working a day tour in B98 and have just arrived at an explosion in a subway station that is the last station before the tube crosses the river into Queens. Upon your arrival you are told by an NYPD ESU Captain that a terrorist detonated an IED in an attempted chemical attack, but the chemical did not release and is contained at this time. He also says there are numerous injured passengers and some minor structural damage to the station. The Deputy Chief, who just arrived, turns to you and asks you the Battalion Chief the following two questions: Who is the IC at this incident, us or the NYPD? Since an IED was detonated we shouldn’t allow cell phone and handie talkie use within how many feet of the incident? You would be correct to tell the Deputy Chief? (5.3, 5.7, AUC 276 6.1)
A. The FDNY is the IC / 300’
B. The NYPD is the IC / 150’
C. The FDNY is the IC / 600’
D. The NYPD is the IC / 1000’

20. B

6.1 CIMS states that the NYPD is the Incident Commander for CBRN/Haz-Mat Incidents where crime or terrorism is suspected or has occurred. A Unified Operations Section will be implemented in all circumstances, based on agency Core Competencies, with FDNY responsible for life safety and mass decontamination, and NYPD responsible for overall site
management and crime/terrorism assessment and investigation. As soon as NYPD determines the incident does not involve crime or terrorism, a Unified Command is formed between FDNY and NYPD. For chemical incidents, DEP will make final adjustments to hot, warm and cold zones and direct mitigation. For biological or radiological incidents, DOHMH will make final adjustments to hot, warm and cold zones and direct mitigation.

21

21. FDNY members are operating at a serious train derailment in an under river tube. Since this incident occurred at 3 am there are not many patients on the train. The Rescue Company performing recon of the train notifies the IC that there are approximately 20 passengers on the train with various injuries. The Rescue Officer reports there are:
- Five ambulatory victims.
- Five non ambulatory victims, two of which are red tags and three who are yellow tags.
- Five red tag victims requiring extrication.
- Five black tag victims.
The victims should be removed in which order below? (7.1)
A. Ambulatory victims, non-ambulatory victims (yellow tags first then red tags), red tag victims requiring extrication, and the black tag victims.
B. Black tag victims, ambulatory victims, non-ambulatory victims, and the victims requiring extrication.
C. Ambulatory victims, non-ambulatory victims (red tag then the yellow tag victims, black tag victims, and the victims requiring extrication.
D. Ambulatory victims, non-ambulatory victims (red tag then the yellow tag victims), victims requiring extrication, and the black tag victims.

21. D

Victims should be removed in the following order:
7.1.1 Ambulatory Victims
Evacuate passengers who have walked from the incident to the emergency exit.
7.1.2 Non-Ambulatory Victims
 Red Tag (Immediate Transport)
 Yellow Tag (Delayed Transport)
7.1.3 Victims Requiring Disentanglement/Extrication
 Red Tag (Immediate Transport)
 Yellow Tag (Delayed Transport)
7.1.4 Black Tag (deceased victims)

22. Planning and logistics are an important aspect to operations since a massive search and rescue operation will present FDNY Units with many obstacles to overcome. Which point listed below is incorrect regarding planning and logistics at an under river rail incident? (6.2, 6.3)
A. Plan tactics in the proper sequence. For example, carrying bulky equipment down an emergency exit while the exit is being used for evacuation will save time and maximize the use of the exit.
B. Determine what can be done to maintain the highest degree of safety for operating members. Establish sectors, groups and task forces as necessary to maximize efficiency and control.
C. Ensure availability of APR adaptors and canisters. Even if continuous SCBA use is not necessary, we can expect large quantities of dust, including steel dust, to be airborne.
D. Lighting methods should cause as little noise and heat buildup as possible. Monitor for CO buildup when using generators to operate portable lighting. Consider the use of glow sticks, hand lights, and portable lighting.

22. A

6.2.4 Plan tactics in proper sequence. For example, don’t be carrying bulky equipment down an emergency exit while the exit is being used for evacuation.

23

23. At a recent incident in an under river tube, ambulatory patients walked to the base of an emergency exit and were directed to continue walking along the track to the nearest station which was about 750’ away. The decision to move passengers along the track to the nearest station will be based on all of the following factors except which one? (7.2.2 A)
A. The patient’s condition.
B. The smoke condition in the tube.
C. The status of the 3rd rail power.
D. The travel distance.

23. B

A. Direct passengers to walk along the track to the nearest station The decision to move passengers along the track to nearest station will be based on travel distance, patient condition, and the status of 3rd rail power.

24

24. Safety is paramount at any operation but especially in an under river tube. There are many factors that can lead to unsafe operating condition such as heavy smoke condition, high heat, water from a ruptured tube, and moving trains to name a few. Which point below regarding safety at an under river rail incident is incorrect? (9.1)
A. Once committed to the tubes, members must realize that the route they approached from may be their only means of egress. Conditions at the scene may not allow members to pass to the other side of the incident
B. An explosion, collision, or derailment would generate large amounts of airborne dust. In addition to being a respiratory hazard, the dust would severely affect unprotected eyes.
C. Third rails in the affected tube and in adjacent tubes may be live. In addition, 1,000 volt lines may run throughout the tubes at ceiling level. These lines are deactivated by routine requests for power removal.
D. Numerous severe injuries will result in body parts and bodily fluids at the incident scene. As time passes, high heat conditions in such an enclosed area will result in tissue decomposition.

24. C

9.1.1 Electrical Power
Third rails in the affected tube and in adjacent tubes may be live. In addition, 1,000 volt lines may run throughout the tubes at ceiling level. (Figure 16) These lines are not deactivated by routine requests for power removal.

25

25. It is critically important that FDNY members operating in an under river tube understand how to use a power removal box in order to remove power in an emergency life threatening situation. Which choice below is incorrect regarding power removal and the blue light phone? (AUC 207 8.1, 8.2, Under River Rails 2.9.7, 4.5)
A. Contact shoes are pieces of metal that conduct electricity from the third rail to car motors. They stick out from the sides of the car near the wheels. There are contact shoes on both sides of the cars. If any contact shoe is on the third rail, all contact shoes of car will be energized.
B. Whenever NYC Transit personnel determine that a Power Removal Box or the Telephone is out of service, they will be covered with a bag to identify them as being out of service. This bag will be white, with red lettering, and it will state Out Of Service.
C. If a member encounters an out of service power removal box, the member should go to the next closest power removal box and use this box to shut the power and contact the Rail Control Center (RCC) to request the removal of power.
D. To operate the telephone at a power removal box, remove the handset from inside the box and depress the button on the handset, keeping it depressed at all times during the conversation. Releasing the button will terminate the call.

25. C

If a member encounters an out of service Power Removal Box, the member should use the associated Telephone to contact the Rail Control Center (RCC) to request the removal of power. The member must identify him/herself, state the reason that the power must be removed, and
remain on the phone until they receive confirmation that power has been removed.

26

26. True or False? A blue light phone can be used to call outside the system and can receive calls from outside the system. To call a blue light telephone from outside of the system, dial 1 + the area code (usually 718) + the three digit exchange + the four digit extension number. (2.9.7)
A. True or B. False

26. B

 A blue light phone cannot be used to call outside the system, but can receive calls from outside the system. To call a blue light telephone from outside of the

7.3.1 Victim Removal Relay Teams may be used to remove non-ambulatory victims. Teams would spread out from victim location to emergency exit. Victims would be passed from team to team in a relay fashion. This action would prevent carrying teams from having to pass each other in a narrow space. The relay concept has been tested in FDNY exercises and found to be a more efficient method of moving large numbers of patients over significant distances.
7.3.2 SKED stretchers have proven to be useful to move patients long distances over
difficult terrain.
