G-FFOU Firefighting Operations Underground

Study Notes

Factors to consider for firefighting in underground areas include control of lobby and elevators, stairwells for smoke migration and removal, and entry and exit of persons and vehicles.
Smoke migration and contamination of multiple floors is a concern, as well as the need for effective communication systems and limiting the number of firefighters committed to the underground area until the fire is located.
Firefighters should wear complete personal protective equipment (PPE) including SCBA, and Thermal Imaging Cameras should be used to locate the fire and possible victims.

All high-rise firefighting operations should comply with Standard Operating Guidelines and Training Notes.
The first arriving company officer should position the apparatus to determine the location and extent of the emergency and establish the Incident Management System.
No entry is permitted without Entry Control.
Once the exact location of the fire is determined, it should be announced to all personnel operating at the incident.
Sprinkler and standpipe system connections should be made by a First Alarm Pumper at the scene.

Firefighters should enter with firefighting equipment including 65mm Hose Packs and Standpipe Kit, forcible entry tools, utility rope or hose line, and portable hand lighting.
Additional equipment may include lifeline or rope reel, SCBA with 60-minute cylinder air supply, and Thermal Imaging Camera.
A hose line should be deployed from the apparatus to the fire, if possible, and doors leading directly into the building from the underground area should be kept closed to prevent smoke contamination.

Entry into heavy smoke in underground areas should only be made by firefighters wearing complete PPE and in constant contact with a hose line or lifeline leading to a safe area.
The Incident Commander should designate a RIT crew(s) immediately and ensure the EVAC system is used and periodic updates are issued to occupants.
Firefighting personnel should ensure the power is disconnected to the electric door closer prior to entry or an auxiliary device is in place to prevent the door from closing.
Company Officers of each entry team should ensure the locking mechanism on all doors through which they pass are disengaged, unlocked, held open, or rendered inoperative to allow for escape.
