Chap 12 Multiple- Family Dwellings Flashcards
These dwellings are occupancies that house three or more families and come in all shapes and sizes. These buildings have complex layouts that present serious life safety risk to fire fighters.
Multiple-family dwellings
Effective and of the response area are critical components when applying fire ground strategies and tactics.
Preplanning and knowledge
In large, multi-family dwellings, where should the accountability officer be placed?
At entry points
General priorities for a multiple-floor search include:
- Fire floor
- Floor above the fire
- Top Floor
- The rest of the building.
Form of isolation that provides a level of protection while leaving people in place, usually homes or unaffected areas of large buildings.
Shelter-in-place
Possible avenues of fire extension in Older multifamily apartment dwellings.
- Pipe Recess
- Utility shafts
- Air/light shafts
- Dumbwaiter shafts
- Renovation /alterations
- autoextension from floor to floor
For basement fires in multifamily dwellings it is important that the house line is stretch where and why?
Front door to the cellar stairs to protect the interior hall for occupants who are trying to evacuate.
Getting the between the buildings occupants and the fire may save more lives than trying to perform multiple rescues.
Initial hose line
Ways to get to the roof of an old apartment multiple dwelling? What must you do one you made it to the roof?
Adjoining building or aerial.
Must avoid interior stairs.
Ventilate by opening bulkhead/scuttle
These can be accomplished by vertical ventilation
- Relieves upper portions of heat and smoke
- allows for a thorough search above the fire floor
- Creates a vertical flue for smoke and heat removal
- limits horizontal fire spread
- Increases victims chances of survival.
How should a double hung window be opened during horizontal ventilation?
Two thirds at the top, one third at the bottom
Biggest structural difference in newer apartment buildings?
Introduction of unprotected steel I beams
The component of a building that connects two wings.
Throat
What are newer apartments interior stairways constructed with?
Fire resistive materials ( metal threads with marble stairs and landings) surrounded by fire resistive walls.
The extensive use of these allows a path of fire travel in newer apartments.
Steel I beams
One 50 foot length of hose stretched through the well of stair way can reach how far?
5 floors
A cut for ventilating a confined in which the cut is the entire distance of the roof; useful in confining a fire in a cockloft that is spreading horizontally.
Trench cut
When ventilating newer apartment buildings, fire fighters can pull ceilings on top floor to examine cockloft, if fire is in the cock loft what must be done?
Roof cutting should begin immediately.
Using an elevator to reach fire floor is not recommended practice, however, if one must be used where should you stop?
At least two floors below the fire floor and take the stairs the rest of the way.
What floor should you hook up to a standpipe?
At least floor below fire.
Where should the back up line be hooked up to?
At least two floors below fire floor in the same stairway.
General Concern in row frame building fires.
Rapidity with which fire spreads and the great potential of structural collapse
Best way to get to the roof on Row houses.
The use of aerials.
What may be necessary to fire in common cocklofts of row houses?
Trench cut a few buildings down to stop the spread.
These were built in the 1800s and early 1900s, similar to row houses but have noncombustible exterior and brick walls separate each buildings and extend through the cockloft.
Brownstone Multifamily
These dwellings have landscaped gardens and create access to buildings difficult for fire fighters?
Garden apartments.
