Row Frames (construction/fire travel/characteristics)s Flashcards
Row Frames?
- 2 to 5 stories
- 20-30 feet wide
- depths 40-60 feet
- with or without cornices
- stoops similar to brownstones, but all wood
Rowframe/BROWNSTONE type layout?
3 FRONT WINDOws per floor w/one apartment going front to rear and NO REAR FIRE ESCAPE
Rowframe/OLT TYpe?
railroad flat with 2 apartments per floor
- 4 WINDOWS ACROSS, with a rear fire escape
- dumbwaiter shaft
- light shafts
Rowframes are either…?
BALLON FRAME
OR
BRACE FRAME CONSTRUCTION
- these buildings are large rectangular boxes of dry lumber, danger of fire spread in all directions
- INTERIOR CONSTRUCTION similar to tenements and brownstones, usually wood lathe and plaster
EXTERIOR IS WOOD, OR VENEER OVER OUTER WOOD SHEATHING (brownstone have NON COMBUSTIBLE outer shall)
The salient feature common to all, regardless of variation in design is….?
COMMON COCKLOFT
vary in height from 1 foot tall to enough for a man to STAND IN
-common cornices may be present
How do we gain entrance to roof from interior of the building..?
SCUTTLE- iron ladder from top floor
-usually NEAR SKYLIGHT OVER STAIRS (brownstone is closet)
Cellars?
lack of fire stopping-fire travel from one cellar to another, sometimes cellar runs under more than one building with no separation
-common partition walls between building permit fire spread
LIFE HAZARD IS GREAT duet to the LARGE NUMBER OF OCCUPANTS and RAPIDITY OF FIRE SPREAD
Major defects or faults in construction are the…?
LACK OF FIRE STOPPING
and
QUANTITY OF COMBUSTIBLE MATERIAL
HORIZONTAL fire spread?
COMMON COCKLOFT
- common cornice
- common cellars
- wood cellar beams
- thins flimsy walls BETWEEN BUILDINGS
- via WINDOWS and SIDING TO ADJOINING BUILDINGS
presence of store may add to fire…TIN CEILINGS WILL MAKE OPENING UPMORE DIFFICULT
Vertically:
- pipe recesses
- via light/air shafts
- auto exposure front /rear windows/siding
- interior walls/partitions
DANGER OF COLLAPSE with FIRES in this type of structure is …?
A FACTOR DESERVING CONSIDERATION
Collapse..?
- heavy fire in cockloft will burn roof supports and collapse roof into top floor
- rear walls can pull away from the building and collapse in one section
- collapse of sidewalls is a danger, especially true when building in a ROW HAVE BEEN DEMOLISHED OR REMOVED
- when a serious fire burns out the entire first floor, there is a danger of collapse, especially in corner buildings and buildings standing alone
- steel plating on interior/exterior walls will add to weight of collapse
- weight of FIRE ESCAPE can cause COMPLETE COLLAPSE of an exterior wall
VISUAL check of rear and sides from ROOF LEVEL, is responsibility of…?
1st LADDER
2nd ladder- CHECK REAR AND SIDES FOR EXTENSION AND VICTIMS
For fires on the TOP FLOOR…2nd LADDER WILL…?
check EXPOSURES for extension
Light fire situation…?
fire which can be extinguished with the operation of one handline and /or hand extinguisher or those that can be readily extinguished without resorting to extinguishing agents
MEDIUM FIRE SITUATION?
indicates a FIRE WHICH CAN BE EXTINGUISHED WITH THE OPERATION OF 2 HANDLINES
At a TOP FLOOR FIRE, (BROWNSTONE TYPE LAYOUT)who is responsible for VEIS of top floor and EXAMINATION OF COCKLOFT?
1ST LADDER -INSDIE TEAM
AT A TOP FLOOR FIRE (BROWNSTONE TYPE), the 2nd LADDER WILL..?
SPLIT COMPANY AND EXAMINE EXPOSURES 2 AND 4 for extension
TOP FLOOR fire, (OLT TYPE)…1st LADDER INSIDE TEAM..?
VEIS of the FIRE APARTMENT-examine cockloft
2nd LADDER TEAM at TOP FLOOR FIRE (OLT type layout)..?
VEIS ADJOINING APARTMENT- examine cockloft
1ST DUE- LCC…?
shall no operate in a manner that will in any way impeded their return to the pedestal and cause a delay in positioning or repositioning the aerial for rescue or removal operations
-THE LCC MUST NOTIFY THE COMPANY OFFICER OF INTENDED DESTINATION WHEN LEAVING THIS PRIMARY POSITION
LCC- COMPLETE COVERAGE…UNABLE TO DO SO..?
NOTIFY INCIDENT COMMANDER
LCC raise aerial to roof, then?
WAIT FOR COMPLETION OF ROOF SIZE UP
ROOF indicates NEED FOR LSR..?
LCC will proceed to the roof to assist
Variation from normal LCC duties..?
KNOWN LIFE HAZARD
- aerial ladder/portable ladder rescue in front of building
- LSR RESCUE
In a RF (brownstone type) LCC will VEIS.?
TOP FLOOR (team up with 2nd LCC)
In a RF (OLT type) LCC will VEIS..?
FIRE APARTMENT (team up with 2nd Lcc) -then adjoining , then floor(s) above
Fire on 1st or 2nd floor, VEIS..?
FROM PORTABLE LADDERS
FIRE ON 3RD FLOOR AND ABOVE?
AERIAL
OV…TOP FLOOR FIRE?
1ST DUE LADDER
SAW AND HALLIGAN
OV..TOP FLOOR FIRE..?
- proceed to roof and descend FIRE ESCAPE FOR VEIS
- unable to descend, NOTIFY LCO and attempt to vent fire apt. from roof, then assist with roof vent
At BROWNSTONE type ROWFRAMES…?
10’ HOOK OR 10’ SCISSOR LADDER can be taken to rear to assist with venting or gaining access
