Standpipe Operations Flashcards
Standpipe systems should be supported at the (blank) as outlined in FOG #
FDC; 2.3.015
How much hose is recommended for crews fighting fires using standpipe?
150’
Class I and II FDC’s require connection every (blank)
130’; class III can exceed 130”
What is the minimum size hose allowed for operating from a standpipe? Recommended? Why?
1.75”; 2.25” due to lower operating pressures
What nozzles are allowed for operating from a standpipe? Why?
Smooth bore only; lower operating pressures, easy to pass rust, debris and objects
At no point in time should crews (blank)
utilize hose provided in the FDC, always bring your own
Crews will initiate operating (blank) floors (blank) the fire if operating off standpipes
1; below
What is the listed sequence for making standpipe connections?
2.5” ball valve, 2.5” pressure gauge; hose and nozzle
List the problems that may be found at the standpipe valve.
Chained valve, broken valve handle, broken valve or stripped head on valves, PRV
How would you defeat a chained valve?
bolt cutters or irons
How would you overcome a broken valve handle?
utilize a spare valve handle or utilize the pipe wrench to operate the valve
How would you overcome a a stripped head on the valve?
Call command or engine on FDC, request FDC to be shutdown, completely remove the valve with the pipe wrench, put the 2.5” ball valve onto the standpipe (threaded adapters)
How would you overcome a PRV?
Removing limiting pin or use field adjustment wrench
Crews should not make connections (blank)
At the fire floor or floor above
What other alternative options in the event of FDC failure?
Supply standpipe at the ground floor, use aerial device as a elevated standpipe; hand-jack LDH up stairwell
What adapter is going to be required is supply the standpipe on the ground floor?
Double female
AO’s will supply an appropriate pressure to standpipe not to exceed (blank).
180 psi
What will keep water from back-flowing out the system if using the first floor standpipe to supply the system?
Back-flow prevention, required per national plumbing code
What must be in place when using an aerial master device as an elevated standpipe?
2..5” ball valve
Hand-jacking LDH into a stairwell to supply lines should be utilized as (blank)
a last choice
In commercial structures what may prevent the use of aerial devices as flying standpipes?
Encased lexan windows
Anything over (blank) floors, 2.25” or 3” hose may not be acceptable for use as supply hose due to (blank)
3 floors; overall length and friction loss
If using 5” LDH in the stairwell as supply line, IC should call for (blank)
additional resources and extra alarms
Crews will stretch LDH up the stairwell to (blank).
Floor below the fire.
