Flashcards in Ch. 15 Garden Apartments and Townhouses Deck (18)
Townhouses are similar to _______ but are __________. They normally ________ common cocklofts or crawl spaces.
One-family private homes (room size/fire loading).
Attached to other homes on each side.
Townhouses typically have ____ or more floors (as many as ___ living levels found in split-level designs of ____ story bldg). connected by an OPEN INTERIOR stair.
Individually owned homes with common party walls
Common problems for garden apartments and townhouses (4)
Layout complex itself and access for apparatus).
Bldg to bldg extension = closely spaced bldgs, wood-frame constr. and roofing/siding combustibles.
Hydrant spacing and flow are often deficient.
Access/egress to complex itself may be a challenge (high-security)
Long hose stretch countered by:
2 1/2 in. with break apart nozzle.
-connect 1 3/4 in to nozzle.
-if it's bad, 2 1/2 back in service for exposures.
1 3/4 on gated wye/water thief from 3 in.
Garden apartments are usually: (height)
1-3 stories, can be as big as 6 stories (wood frame)
Biggest difference between fire ops in these bldgs and other apartment bldgs is due to:
Prevalence of lightweight combustible construction.
-sudden catastrophic collapse
Fire in the voids.
Realistic evaluation of life hazard and likelihood collapse should prompt:
Overwhelming blitz attack from position outside collapse zone
Ch. 15 garden/townhouses, 2-3 story apartments and collapse zone danger isn't _____ but rather ______ and ____.
Floors and roofs
Key weapon taken away for truss bldgs that was used on old-style row frame when cockloft fire was discovered:
With no roof vent, how do we cut off fire in cockloft? Ch 15 garden/town
Behind Defendable Barrier.
Preferably fire wall.
Preferably above the roof.
-more likely PARTY wall
-from foundation (through cockloft) to at least roof boards
Garden apartments noted for common void space unusual in most other occupancies:
Common cellar, basement or crawl space.
-space for common laundry facilities.
-source of significant number of fires.
Under the ENTIRE ROW of buildings
Ch. 15. Exposures are 1, 2, 3 and 4. What direction?
2-exp. to left (after that is 2A, 2B...).
3-exp. to rear.
4-exp to right
Largest losses in garden/townhouses is when:
They are being built (Open-framed stage).
No gypsum board, doors or windows
Each apt has its own living space on only one floor, although smaller complexes may be built like townhouses with two-story apartments.
Often have a common cockloft.
Normally no interior stair
Several factors that could defeat a defensive strategy: (3)
Mansard roofs-wrap around division walls, allow fire to sneak around them in large volumes.
So called "fire walls" are not true fire walls, not meant to be self-supporting.
Fire that burns out the joists/trusses on the fire side of a party wall and may result in some structural damage to the party wall.
Party walls have joists or trusses from both sides of the wall laid on the top of each story either ________ or _______.
Side by side.
