65 psi, highest standpipe outlet
100 psi
beats me
when must PRVs or PRDs be used?
when standpipe system pressure exceeds maximum allowable limit, usually 175 psi
What type of PRDs are usually threaded onto an outlet and easily removable?
orifice plates and mechanical devices
What are the 3 types of PRDs?
orifice plates, mechanical devices, valve restrictors
____ are usually removable or adjustable with a screw-driver and this is a recommended practice for field ops.
valve restrictors
some new types of ____ are fireground adjustable (adjustable with valve open and flowing water).
PRVs
what step critical when setting up for a stairwell stretch due to poor conditions on fire floor?
deploying SP pack in hallway below fire floor so officer can get idea of layout and necessary hose length
which side of door should nozzle be on for hallway stretch? stairwell?
hinge
lock
the first step of any high-rise water supply operation is ___. the next step is __.
finding the FDC
spotting apparatus close enough to deploy 3” to FDC
what type is recommended for an aerial blitz?
solid or straight
if a building has separate FDCs for different sections of the building, when should you consider supplying both sections?
location of fire is in doubt
What should be done if the building has separate FDCs which require different pressures? And requires tandem pumping?
use a second engine
tandem: engine at hydrant can be used to supply the lower pressure FDC
where in CAD incident notes can you find required system pressure?
premise hazard section
when should 3” hose being used to supply the FDC be secured and protected?
when system pressure is above 225 psi
TM recommends one method for keeping pump cool in standard water supply, and a different method for tandem pumping supply ops. what are they?
Standard: crack tank-fill
Tandem: flow water through booster or bumper
what is the preferred method and first choice of starting an electric fire pump?
put the pump control level in MANUAL position
At a high-rise, personnel assigned to check the operational readiness of the pump should report their findings to ___. What about at a Mid-rise?
Command
Mid-Rise is WSGS

Lobby Control should send the bldg engineer to ___, and bldg manager to ___.
engineer to FCR
manager to CP
which radio channel should Lobby Control Officer monitor?
primary firetac, for direction from Logistics to switch to alternate
*if possible, get 2nd radio to monitor Direct16, or have FF monitor.
who is responsible for procurement (if not already done) and return of Knox Box and FCR keys?
Aerial/Rescue Specialist staffing the FCR
any crew given a set of bldg keys, should also get a fire phone. who else should get a phone?
member operating elevators
if needed, who can assist with comm between FA and CP?
member staffing FCR
Who can use the HVAC system for smoke removal? Shutdown?
bldg engineer, only after command approval
FD personnel can shut down on order of command- no other action taken w/o bldg engineer
Ensure stairwell pressurization control is on ___. If fans aren’t running then ___.
auto
turn it to “on”
There will usually be a button the ___ that will allow a FF to manually disable which doors?
FACP
stairwell
All high-rise bldgs have a standby emergency power generator, usually ___ powered. how long can they run?
diesel (2 hrs) or natural gas (indefinitely)
where are generators often located?
near the fire pump room
check the generator to ensure ___ is in the “on” position.
transfer switch
where can the emergency generator low fuel alarm be monitored?
in the FCR on the emergency generator panel
is it okay to allow occupants back in when the bldg is powered by emergency generation?
no.
Which stairwell should Recon use?
evac
what are the duties of Recon Group?
floor above duties
seach and evac
vert vent
Recon’s floor-above duties include:
checking for fire extension and search/evac
What factors should Recon consider when deciding whether to carry hose for extension-check or search and rescue equip?
occupancy type and time of day
Recon should report to ___ if smoke is entering ___ stairwell.
Command
Evac
What item/s should Recon obtain from the FCR?
key and fire phone
which occupants are not good candidates for protect-in-place?
those on the floor above the fire
Extension check varies depending on ___.
whether building type if commercial or residential
where should Recon check for extension in a commercial type?
along periphery (especially if glass curtain wall), utility core, and for auto-extension if self-vented
where should Recon check for extension in a residential type?
as with apartment fire… kitchen/bath areas where pipe chases tend to be, and for auto-extension if self-vented
What should be used to start the search for fire extension?
tic
If the fire extends to the floor above conditions can change rapidly, crews searching floor above must ____.
employ hose and/or rope orientation
Recon will need to requests additional companies from Command or Ops. How many additional companies may be needed for: Floor Above duties, Search/Evac, Vert Vent?
Floor Above: 1-2 companies
Search/Evac: 1 company per 2-3 floors
Vert Vent: 1 company
Recon should deploy hose from the ___ stairwell, unless ___.
evac
significant smoke conditions, then inform Command and consider going to next floor above
Recon should closely coordinate ventilation with ___. Who should communicate the need for ventilation early on?
Div X or FA Team
Dix X or FA1
Recon Group supervisor will initially be responsible for which activities?
safety, op/coordination of floor above duties, search and evac, vertical vent
