Study Notes

Accountability/Entry Control

Entry Control should be established at the forward-most safe location within the proximity of the entrance to the controlled area.
The location should be chosen with smoke, fire, and civilian crowd conditions in mind.
Common areas can be at street level, in the station, or other obvious points of entry.
If TFS crews reach the end of the platform area and investigation is required further into the tunnel at track level, 60-minute cylinders are required, and another Entry Control area should be established at this Sector with the Sector Officer/Entry Control being on air if required.

Firefighting Operations

IC's should consider all access points, emergency exit shafts, EEB's, subway station entrances, and tunnels for entry and evacuation.
Emergency exit shafts are extremely dangerous and should not be used for TFS crews or TTC passengers, but may be used to lower or hoist equipment to track level.
In the event of an incident in the subway that requires moving people or equipment on the track system, the IC shall request at least one Subway Emergency Rescue Vehicle (SERV) be brought forward to the scene.
SERV Carts are placed at track level at locations at either EEB's or at the end of subway station platforms.
IC's shall advise TFS Communications to have additional apparatus respond to the next station in the direction and relation to the fire if needed.
Prior to entering track level, TFS crews shall request an Emergency Power Cut/Trip to the Third Rail and to the Track Switches if the Track Switches are near the emergency incident location.

Ventilation

All TTC subway stations have a Fan Room(s) housing high-capacity fans.
The Fan Room(s) shall not be accessed without a TTC staff member as fans are activated remotely, without warning.
The activation or de-activation of fans and louvres for the tunnel shall be coordinated with the TTC IC to ensure proper removal of smoke and maintain control of flow paths within the tunnel for the safety of passengers and TFS crews.
TTC Transit Control Centre controls all fans and louvres in the subway system.
Fans, louvres, and vents are strategically placed throughout the subway system for ventilation purposes.

Rapid Intervention Team (RIT)

RIT shall be equipped with 60-minute cylinders.
A separate SERV Cart should be considered as part of the RIT equipment being staged.
The SERV Cart should be brought forward to the scene if needed.
