Q

Collapse considerations at Row Frame building fires

A
  • Rear walls can pull away and collapse in 1 section
  • Heavy cockloft fire can cause roof to collapse onto top floor
  • Corner buildings and stand alone buildings have an increased danger of collapse particularly if the fire bunted out the entire 1st floor
  • Indiscriminate removal of structural members during overhauling can cause a partial or complete collapse of the building

Q

Construction features of Row Frame buildings

A
  • Common cockloft form 1 foot high to height of a man
  • Light & air shafts are found in some buildings of longer length
  • Lack of fire stooping at cellar ceilings may permit fire travel to an attached exposure
  • Wood cellar beams from adjoining buildings resting on a common wall may spread fire to an exposure
  • Fire may spread from the roof of one building to the roof of an adjoining building
  • In the old law tenement type layout with 2 apts per floor the partitions that separate the apartments are NOT fire stopped between the ceiling of one floor and the underside of the floor above

A
  • 1st line - into the fire building
  • 2nd line - top floor of most severe exposure
  • 3rd line - top floor of opposite exposure
3
Q

Concerning Row frame buildings if a floor is fully involved from front to rear it is

A

Advisable to call for an additional engine and ladder above the full 1st alarm

4
Q

Concerning Row frame buildings if 2 buildings are fully involved we have a

A

2nd alarm situation

5

A

2nd alarm must be considered

6

Promptly consider transmitting a 3rd alarm

7
Q

At a 3rd alarm cockloft fire involving 4 buildings the correct tactics are

A
  • Set up a perimeter of lines consisting of heavy caliber streams in the front and rear and 1 3/4 lines flanking the sides of the fire and moving toward the center of the fire
  • Pull ceilings on the top floor after charged hand lines are in position and IF POSSIBLE after the cockloft has been vented from above
  • As the fire becomes more controlled 2 1/2 lines operating in the front and rear can be converted to 1 3/4 lines and advanced via the rear fire escape and the front entrance of the center fire buildings
