Q

How should passengers be evacuated from an under river subway tube?

A

Evacuate passengers along space OUTSIDE of running rails, OPPOSITE 3rd rail.

A

No

22
Q

Is there repeater coverage INSIDE most emergency exit stairways?

A

No

Q

To ensure maximum repeater coverage, the I/C should?

A

Ensure that a member operating on the repeater channel is at street level in a position at the CLOSEST station on BOTH sides of the river.

24
Q

Blue light phones are found?

A

Near the emergency power removal boxes, approximately 600’ apart.

25
Q

Who can you call from this phone?

A

The T/A trainmaster or the phone in the token booth of the nearest station.

26
Q

Who carries T/A portable radios?

A

a) Conductors
b) Train Operators
c) T/A supervisors
* These radios MAY NOT work above ground.*

27
Q

Is it good practice to use the Post Radio during subways operations?

A

No. Do not use post radios in the immediate vicinity of
a) signals
b) communications equipment or
c) train operator cabs
due to the possibility of electrical interference.

28
Q

Who do we notify when utilizing the Post Radio?

A

Notify NYCT.

*They may be useful to communicate ABOVE ground from one side of the river to the other.

29
Q

What are the parameters of the blue light phone?

A

It CANNOT be used to call outside the system but can RECEIVE calls from outside the system.
1+area code (718)+three digit EXCHANGE+four digit EXTENSION.

30
Q

Where are the NYCT under river tube reversible fans located?

A

At both ends, USUALLY in the vicinity of the emergency exits NEAREST to the water.

31
Q

What are the exceptions to the reversible fans?

A

There are no fans on the Brooklyn side of the Greenpoint-Jackson Ave. Tubes OR
on the Bronx side of the 149th St. tubes.
There are no ventilation fans or ductwork in he tubes themselves.

32
Q

Side “A” of the operational guide contains what info?

A

a) Maps
b) pictures
c) Information to locate a particular set of tubes,
d) the associated emergency exits and stations.
* The I/C can use this side to determine where to assign resources.
* Individual units can use it to understand where they need to go to carry out their assignments.

33
Q

Side “B” of the operational guide contains what info?

A

a) Diagram of the tube
b) Information about emergency exits,
c) distances and
d) crossovers.

34
Q

What does the acronym “LIVES” stand for?

A 
Location of incident/Life hazard
Incident information
Ventilation
Evacuation/Egress & access points
Safety
35
Q

If passengers are self evacuating…..

A

Request power-off on the affected tracks.

36
Q

Where will the Command Post be established?

A

In most cases, the initial Command Post will be located at the station CLOSEST to the tunnel, in the BOROUGH of the FIRST ASSIGNED Deputy Chief.

37
Q

Preparations for operations in under-river tubes have three main elements:

A

Reconnaissance
Planning
Logistics

38
Q

Who would be a logical choice as a recon unit?

A

A Rescue or Squad company.
Metering capability
1 hour cylinders
Knowledge of structural issues.

39
Q

The order of victim removal is

A

1) Ambulatory victims
2) Non-ambulatory victims
* Red Tag (Immediate Transport)
* Yellow Tag (Delayed transport)
3) Victims requiring Disentanglement/Extrication
* Red Tag (Immediate Transport)
* Yellow Tag (Delayed Transport)
4) Black Tag - Deceased victims.

40
Q

What three items must we consider if we decide to move ambulatory passengers along the track to the nearest station?

A

1) Travel distance
2) Patient condition
3) The status of 3rd rail power

41
Q

List, in order, the three ways to remove ambulatory victims out of a tube.

A

a) Direct passengers to walk along the track to the nearest station
b) Emergency Exit Stairways
c) Rescue train

42
Q

What are the two possible scenarios for use of rescue trains?

A

1) A rescue train may be used on the track in the ADJACENT TUBE, accessed via the emergency exit crossover or
2) A rescue train on the same track AS INCIDENT.

43
Q

When should potential rescue trains be swept for secondary devices by law enforcement personnel?

A

Prior to deployment.

44
Q

The primary method for moving patients and equipment?

A

Rail carts, which ride on the tracks.

More efficient than any other method

45
Q

What four options are available to remove NON-Ambulatory victims from a tube?

A

1) Victim removal teams
2) SKED stretchers
3) Rail carts
4) Rescue trains

46
Q

What is one of the most important INITIAL DUTIES of SOC units?

A

Atmospheric monitoring.

47
Q

For extended operations into a tunnel with a distance of UP TO ____’ FROM THE POINT OF ENTRY, consider using SOC units with their supplied air cart and hose.

A

300’

48
Q

What is the voltage of the lines that run throughout the tubes at ceiling level?

A

1,000 volts

These lines are NOT DEACTIVATED by routine requests for power removal.

49
Q

What are indications of train movement?

A

Increased noise levels and powerful air movement.

50
Q

Indications of an approaching train are…..

A

A distant light reflecting on the running rails or vibration in the tracks.

51
Q
