Study Notes

Responsibility

All personnel are responsible for understanding and following TFS Standard Operating Guidelines (SOGs) and TFS Training Notes relating to the TTC.
The Incident Commander (IC) is responsible for developing an Incident Action Plan (IAP) and ensuring safe, efficient, and effective management of the emergency incident.
The IC is responsible for implementing Unified Command with the TTC Incident Commander (IC).

Firefighter Equipment

When responding to a fire in a subway station, firefighters should be equipped with: • SCBA (60-minute cylinders if proceeding into the tunnel at track level) • Minimum of one Thermal Imaging Camera per crew • 65mm Hose Packs and Standpipe Kits • TTC access keys
Additional equipment to consider: • Class ‘C’ extinguishers • One set of forcible entry tools (30” halligan and flat head axe irons) • Search Ropes • Entry Control Kit • Bull Horn

Safety Precautions

Always treat the Third Rail as live, even after performing an Emergency Power Cut/Trip.
Track/Rail Switches are still operational even after an Emergency Power Cut/Trip to the Third Rail has been performed, as they receive power from a separate source.
Do not step on or near Track/Rail Switches.
Do not step beside the control box as they are operated automatically from a remote location.
Request assistance from the TTC Transit Control Centre if needed.
A Catwalk is the walking area through the tunnel, which is on an elevated platform above and beside the track bed.
The minimum width of a Catwalk is 600mm (24 in) throughout the tunnel.
If the Catwalk width is less than 600mm (24 in), it is identified as a non-clearance area.
TFS crews shall never walk on the Catwalk when a train is in motion.
Collector Shoes must be treated as “live”, and contact shall be avoided.
Running Rails, Crossovers, Drainage Ditches, and Paper Catchers are trip hazards to be aware of while working at track level.

Minor Smoke, Minor Fire or Burning Odour Responses

TFS will not be responsible for investigating these types of incidents unless specifically requested by TTC through TFS Communications.
The TTC IC may exercise caution in investigating and extinguishing small fires not exceeding 30 metres (100 feet) into the tunnel.
If investigation by the TTC IC would require exceeding 30 metres (100 feet), TTC policy requires the TTC IC to return to the platform and await assistance from TFS.

TTC Definitions

Burning Odours: A burning odour is the property or substance in the air, typically emitted from combustion and activates the sense of smell.
Minor Smoke: Minor smoke can be described as a haze, and can be seen 500 ft through the smoke.
Minor Fire: A minor fire is a fire in the incipient (growth) or smoldering (decay) phase and may be easily extinguished by a single person with a fire extinguisher.
