Rowframes Flashcards
Rowframe bldgs will be either _ or _ construction
Balloon frame or Braced frame
Salient feature common to rowframes
Common cockloft spreading over all the bldgs in the row. 1’ to tall enough for a man to stand in
Major defects or faults in the construction of rowframes
Lack of fire stopping and vast quantity of combustible material used in construction.
Rowframes: a serious fire burns out the entire 1st fl, there is a danger of collapse. Especially in _ bldgs and _
Corner bldgs and Stand alone bldgs
Rowframes: are partitions that separate apts fire stopped between the ceiling of one floor and the underside of the floor above
NOT fire stopped. May permit lateral extension across the bldg and heavy smoke condition in the apt which is not directly over the fire apt

TL supply
Rowframe fully involved- can 1st three HLs be stretched into 3 different bldgs?
Yes: 1st HL fire bldg
2nd HL: BU 1st HL or if not needed then top fl or most severe exposure.
3rd HL: if 2nd HL BU 1st HL, 3rd HL to top fl of most severe exposure. If 2nd HL at most severe exp 3rd HL to top fl or fire bldg or opposite exposure
Rowframes: T/F any HL stretched after 1st line and 2nd line will be under the direction of a Chief
True.
Vacant in a row of Occupied Frames “VOM FOFO”
Vacant Occupied
Most severe exposure 1st HL
Fire bldg or Opposite exposure 2nd HL
Fire bldg or Opposite exposure 3rd HL
Additional Eng and Truck at rowframe fire
When a floor is fully involved in fire from front to rear a full 1st alarm assignment req’d. Advisable for an additional Eng and Truck.
2nd alarm at rowframe fire
2/more floors fully involved, or top flr fire has extended to cockloft, 2nd alarm must be considered. 2 bldgs involved- 2nd alarm
3rd Alarm at rowframe fire
Prompt consideration must be given to transmitting 3rd alarm if fire extends beyond two bldgs.
Choose incorrect
A. Brownstone type Rowframe will generally have 3 front windows w/1 apt going front to rear and a rear fire escape
B. OLT frame has 2 RR flat apts per fl. Generally 4 windows across the front with a rear fire escape
C. Depth of OLT type will determine size and number of rooms. May have a dumbwaiter or light shaft present
D. Rowframes can be either balloon or braced frame. Balloon construction fire can extend vertically. Braced framing stops vertical ext by use of a girt.
A No rear fire escape usually found
Choose incorrect Rowframe fire
A. Heavy fire in cockloft will burn roof supports and cause collapse of roof into top fl
B. Rear walls can pull away from bldg and collapse in one section into the yard
C. Collapse of sidewalls is a danger. Even when walls bordering the gap are braced, the danger is still present
D. Serious fire that burns out entire top fl, will have a danger of complete collapse, especially in corner bldg and stand alone bldgs
D Fire on 1st floor
Incorrect HL fire on 1st fl Rowframe
A. Brownstone type 1st HL stretched via front door on parlor fl to maintain integrity of interior stairs
B. OLT type 1st HL stretched to location of fire
C. OLT type 2nd HL if not needed to BU 1st HL, stretched to fl above the fire
D. Brownstone type 2nd HL if not needed to BU 1st HL is stretched via front door on 2nd fl to maintain integrity of interior stairs
A Stretched via 1st floor door.
