After above complete all members removed from roof
When encountering a pull down those stair with a rope that gives access to an attic this stair can be used by operating forces to access the attic
No should not be used for access or stretching lines use portable ladders
If encountering two secondary entrances adjacent to each other on the same side of house (exposure 2 or 4) one with stoop one at ground level this usual indicate a
Entrance at ground level will lead into kitchen and cellar
Entrance with stoop will lead directly to second floor
If off set windows are encountered near a secondary entrance (usually with stoop ) it usually indicates that stair goes to second floor and these windows should be used to VEIS if IC GIVES approval
No should not be used to VEIS

Order of preference for roof access of peaked pd is
- TL
- Aerial.
- Portable
When using TL to access the roof of peaked pd what is the preferred position
Parallel to front of building so basket can be placed over corner of building near peak of roof …turntable should be positioned so basket can reach two sides
Placing the basket to cover two sides of pd will facilitate the following
Rescue of occupants on 2nd and 3rd floors
Vent of the front and side
Entering the upper floors when stairs unstable
Overhauling difficulties to reach and unstable areas
If TL basket cannot be placed in its preferred position to reach a peaked roof how shall you position apparatus
Place the basket to the valley area where a hook ladder can be used to each peak
When using an aerial ladder to access the roof of a peaked roof pd you should position the apparatus where ?
Position the apparatus to facilitate raising and extending the ladder over the corner of the building. This permits max coverage of the front and one side of building
Note if cannot be placed adjacent to peak position in valley area where a hook ladder can be used to reach the peak
When using an aerial ladder to access the roof of a peaked roof pd you should place ladde how many feet above the peak ?
5 feet above and to one side of peak
This ensures:
- Easy mounting and dismounting
- Ensure ladder will be visible in heavy smoke
- Prevent members from passing directly in front of and over the upper window as they ascend
Portables are the last option to reach a peaked roof pd. They shall be used if setbacks or other obstructions negate the use of TL or aerials. How can they be used to reach peak ?
- A 35 ‘ extension ladder may be raised to a dormer roof or into the valley on the side of the dormer where a hook can be used to reach peak
- Portable May be used to roof of porch as long as pitch not to steep. Then portable to fro porch roof to main peak ..ensure portable butt end is secured on porch roof prior to ascending
Where should the first hole cut in a peaked roof pd be placed
At the main gable
This allows venting of blind attic space the knee walls and the attic hall and rooms below allowing rapid line advancement and search by the inside team ..prior to vent need permission from officer operating in fire area
When cutting a hole in peaked roof with axe what position shall the member take and where should he cut ?
Work from a position of straddling roof parallel and on the lee side of the ridge
Cutting a hole in a peaked roof with an axes will be limited in size too
A members reach and maneuverability but will generally be about 2x3
In a Queen Anne when cutting the roof with an axe what additional tool should you bring to help vent the roof
10’ hook to push down ceilings
First due roof mans tools at a flat roof pd
Halligen
6 Halligan hook
LSR
Access to the roof of flat roof pd

In cellar fires in pds it is important that first due engine and first due truck coordinate and communicate. Where will the engine stretch and where will the truck proceed
The entrance that provides the quickest access to the basement both 1st engine and 1st truck work together
When no hose line is immediately available for a basement fire in a pd first ladder officer should not down the stairs before a line arrives? True or false
False he may decide advance down cellar without line to conduct a rapid primary search for victims and confine fire . One member should remain at top of stairs for door control. Door control essential without line
When stretching a line to the basement of pd usually the secondary entrance provides the quickest access to basement , the truck must maintain door control to the basement until
The engine advances a charged line via secondary entrance
If using the secondary entrance there is usually an interior door that leads to the first floor at the top of the stairs .. First due should
Close door if found open and communicate this to the second due truck and IC
If first due ladder uses secondary entrance. To gain access to a basement fire then second due should
Provide VEIS of floors above fire
If the secondary entrance is a Bilco style door should you use this door to access the basement
It is the least desirable of the secondary means of entrances and shall not be utilized for hose line placement unless it’s only option
If main entrance to a cellar pd fire is quickest access then first truck will
- Enter through main entrance on first floor
- Initiate searches
- Locate the top of cellar stair to evaluate conditions
- Maintain door control at main entrance door until charged line advances via main entrance
- Communicate findings to IC and officer of first hose line
When decision is made to advance the first hose line through the main entrance and down interior cellar stair then first arriving ladder
will
Perform primary of first floor prior to descending cellar stair to perform primary search of cellar
Engine requires assistance send one member to assist
Remaining two members continue primary on first floor ( officer and one other member )
Critical that first truck support first engine in getting quick water on fire
What are some indications of an open interior cellar door when there is afire in cellar
- Thermal imaging camera showing heat waves emanating across the first floor ceiling when entering first floor via main entrance
- Smoke action seen on the first floor seen at the entrance door- such as smoke showing at significant force and speed under pressure
If there is a secondary entrance and the first line has not advanced down the interior cellar stair than first truck shall
Assume responsibility of primary searches on the first floor and floors above
If conditions permit determine status and and door construction of interior cellar door and communicate to IC
If there is a secondary entrance and the first line has not advanced down the interior cellar stair via the main entrance than second truck inside team shall
Coordinate there advance via the second line into cellar via secondary entrance and assume the primary in cellar

3 feet
3 feet
In two family house, you encounter to door s on the front of the building which door will usually provide access to the second floor
Door near side wall
If operating a line from exterior into the cellar of a pd members in cellar must always be removed first
In emergency such as members trapped by fire or endangered by fire because of collapse IC should order the immediate operation of hoseline into cellar

Know as space joists
General ops at light weight pds
Upon arrival any signs of renovation I building and age included in size ump
Suspect lw in newer type buildings and Reno
When lw suspected immediate examination of ceiling void shall be conducted as soon as conditions permit
Lw system found immediate notification to IC required
Fire found in vertical void attic/cockloft space promptly checked
What should be used to assist in detecting fire and or heat in concealed spaces
TIC SHOULD be used to determine if any heat present in or around gusset plates and c joists
Tic May not detect always detect intensity of fire below
In addition may not detect heat or fire with double 5/8’ sheet rock
What is the primary emphasis for a fire in lw building under construction
Exterior attack unless the fire is minor or concealed to small area
Exterior streams operated from safe area outside collapse zone
Indication of fire in a truss loft is
Presence of smoke pushing at the floor line on the outside of the building
Indication that the probability of collapse is significantly increased
Fire in a a LW constructed building IC shall ask the dispatcher for
Additional engine
Engine ops general at LW pd
- Paramount to position 1st line for contents fire that has not extended
- 2nd line must be positioned to back up first
- If 2nd line used some where else remote from 1st line then 3rd must back up 1st
- Fire is a Such magnitude that cannot be quickly knocked down with two lines consider outside op
Nozzle FF should use which type of stance in a LW construction building ?
Leg forward
If fire In LW construction is severe enough that roof cutting is needed to vent top floor the IC should consider
Exterior ops
Ladder ops general at LW pds
- If LW suspected 1st arriving should make inspection hole in ceiling from safe area in order to determine type of support system .. Done immediately on arrival and notify IC
- If fire on first floor or cellar and conditions perverse visual inspection can examine similar attached ( assigned by IC )
- Before entering any room involved in fire one or more inspection holes should be made .. Ladder officer ensure charged lineup in place before additional holes made notify IC of findings
- After contents fire knocked down open up to check for extension.. Notify IC
- Use caution when overhauling plasterboard on structures provide structure especially with C JOIST construction
- Under no circumstances shall roof be cut on building with LW construction
If fire on top floor and has entered cockloft than
IC immediately notified
Members not permitted on roof
Floor above considerations … Before proceeding to floor above members should consider following :
- Location and extent if fire
- Presence of life hazard ( know or suspected
- Position and progress of the 1st and 2nd hose lines
Who should make inspection holes to determine type if construction If first due hasn’t already
2nd truck
If a member encounters colliers mansion type conditions in a LW pd he should notify
IC immediately
Whst is estimated time of collapse in private dwellings with traditional construction
One hour
Depends on :
- Duration and intensity of fire
- Size of structural components
- Type of construction involved
However if no ceiling to provide protection therefore exposing structural members failure can occur in 2o min
What is the always the primary consideration in pds constructed with light weight construction
Collapse
When fire extends to structural components of pds with lightweight construction collapse can occur within
5-10 min
In pd with lightweight construction where content fire has not extended to the structural components it’s it of paramount importance to
Position the 1st handline for early extinguishment
Unsupported areas that Span greater than _____ feet are a usually indication thst lightweight instruction is present
25 feet
In pds a truss loft is
Enclosed area btwn floors and ceiling where open truss construction is found
Note however ceilings may not be present in basement / cellars
Most common type of peaked roof found in light weight construction
Open web lightweight wood truss
In lightweight pd construction heavy fire on a floor or in cellar with little or no smoke condition on floor or floors above May be an indication of
Concrete or gypsum floor poured over corrugated steel supported by C-joists
Space joist are another name for
Composite truss
When fire is on the top floor and there is a clear indication that fire has NOT entered the cockloft ROOF OPS SHALL BE LIMITED TOO
1 check rear and sides of building
