2/3 s from top and 1/3 from bottom
A roof line in an MD should only be used for
Prevent fire from passing a trench
Protect exposures
Extinguish fire that cannot be reached from below such as fire in a cornice
In a MD who is responsible for informing the IC and members of the manner I’m which the apts and floors are designated
The first officer inside the fire building
Where should the first line go and how should it operate at a stairway fire I’m an OLT?
First line should be stretched up the stairway operated to extinguish fire shut down then advanced further up stairway .. When possible should be operated up well hole. Procedure repeated till line is advanced to top floor
NOTE:
2nd line serve as protection and finish up extinguishment
When operating a line in rooms involved in fire in the vicinity of a shaft and fire is in shaft when should you operate Line up shaft to extinguish fire
After fire in room has been controlled
A fire escape in the throat in an MD MEANS
2 seprate apts
Stack effect in a high rise MD is influenced by all of the following
1 height of building
2 temp differential between outside and inside temps
3 air leakage to other floors
4 wind
When can the doors to the elevator machinery room at roof level be used for ventilation ?
Not until fire is under control and as long as wind will not force smoke back into building
When both engine company and ladder companies arrive together and HRFPMD and only one elevator mom fireman service is available who should enter this elevator?
Truck officer , FE Team , Engine officer , nozzle and control with all rolled up lengths and standpipe kit
If eng and truck arrive at HRFPMD with only one elevator at same time and this elevator is a fireman service elevator with no outside operations who gets in first
Inside team and OVM eng officer and one member of engine
If first due OVM is involved in outside operations and the fire is above the 7 floor of a HRFPMD WHO controls the fireman service elevator
A member of 2 due truck
Or member designated by IC
If the fire in HRFPMD Is on the 7!floor where should the FAST unit and CFRD ENGINE stage
floor below the fire floor
If the fire in a HRFPMD IS ON sixth floor where should Fast/cfrd unit stand fast
As determined by IC
When using the in- line pressure gauge at the standpipe outlet to regulate pressure the control FF should keep it what PSI for 3 lengths of hose and what PSI FOR 4 lengths
3 lengths of 2/12 at 70 PSI
4 lengths if 2/12 at 80 PSI
In a HRFPMD when should the bulkhead be vented and upon direction of who
By orders of the IC and fire has been controlled
Who brings the POST radio In a HRFPMD ?
Second due eng officer
Who insures that Siamese is supplied at HRFPMD
Second Due eng
If a WCD deployment is initiated who is responsible to coordinate this evolution
2nd ladder company officer
When should the ECC of 1st to arrive engine company at HRFPMD charge the standpipe system with 3 1/2 line?
If any evidence of fire present
2nd ECC MUST ASSSIT
A 2nd supply line at a HRFPMD FIRE SHALL be stretch to supply Siamese if ?
- More than one line used from standpipe
- There are indications that system is not receiving engough water , volume or pressure(as determined by HT transmission from ECC /IC OR readings on pump panel flow meter
3 no flow on flow meter a valve is closed in system / High flow indicted pipe may be fractured or outlet valves open on riser
When should the ECC of 1st to arrive engine company at HRFPMD charge the standpipe system with 3 1/2 line?
If any evidence of fire present
2nd ECC MUST ASSSIT
A 2nd supply line at a HRFPMD FIRE SHALL be stretch to supply Siamese if ?
- More than one line used from standpipe
- There are indications that system is not receiving engough water , volume or pressure(as determined by HT transmission from ECC /IC OR readings on pump panel flow meter
3 no flow on flow meter a valve is closed in system / High flow indicted pipe may be fractured or outlet valves open on riser
When estimating pressure for a standpipe you should start whst PSI And add how much PSI per floor
Start at 100 PSI and add 5 PSI PEF FLOOR
What should be included in the standpipe kit
2/12 controlling nozzle with 1 1/8 main stream tip and 1/2 outer tip Hand control wheels 21/2 to 21/2 In line pressure gauge Pipe wrench Spanner wrenches Door chocks Adapters Extra 21/2 controlling nozzle with 1 1/2 to 2/1/2 increaser
I’m cellar fires of a HRFPMD consider using a hand stretch into below grade areas .. When can and engine officer use standpipe
When fire is controlled by the sprinkler system and connecting to a standpipe outlet would not expose our members to an IDLH and engine officer with sound judgement use the standpipe and notify IC
Who will vent the roof at LRFPMD
First and Second Roof FFs
Who will authorize vertical vent at LRFPMD
IC
In a LEFPMD with very long public hallway whst should be brought in addition to normal tool assignment
Search Rope
When can you stretch a 1 3/4 hand line in a LRFPMD ?
If hallways are small meAning every apt door is within 50 of every stairway thst floor
In a LRFPMD with two. Stairways once the attack stairway is selected all ops are to proceed from this star way with one exception?
When roof FFs use the evacuation stair to reach roof
Priority access to the ROOF of LRFPMD is
Stairway in an attached adjoining bld
An enclosed evacuation stairway
Aerial or TL
If a LRFPMD is isolated building with one open stairway and roof access is not possible with aerial or TL how long with roof man remain on roof
Fire is under control and the interior stair is safe to descend
The impact of wind on a FPMD will be effected by the following 3 factors
1.the size of the window opening
2. The fuel load
3 . The stage fire is when widow failed
Who must be notified immediately when wind impacted conditions are noted
The company officers operating inside the building and IC
