27
No other water source will need to be used standpipe system when
The Public Works system supplies enough pressure to satisfy code
28
The exception to public waterworks being the primary water source for standpipe systems, is in what setting
Industrial warehousing more similar, where additional water sources may be required
29
The most common standpipe systems in medium and high-rise apartment and office buildings
Wet system, supplied by public water works
30
These are used to boost the pressure in a primary supply for standpipe which usually Public Works system but could be a water tank
Pressure pumps
31

33
With a gravity tank, the pump is used to fill the tank but not to eight in developing pressure. In the system what supplies the pressure required in the standpipe system
Gravity
34
Pressure tanks are generally found only on what type of standpipe system
Smaller systems where they supply house lines with water for initial attack by the occupants
35
Pressure tanks can be located anywhere in the water supply system and generally do not exceed how many gallons and capacity
3000 gallons
36
What happens after a water supply 10 for standpipe system is empty
It is useless as a source therefore pumper is needed to supply the system
37
That's with dry systems it went system may consist of two or more risers that may be separate or interconnected therefore firefighters must be aware of
The type of system and which one they are working on
38
There is one fire department intake for each riser each and take serves one riser and one riser only in which case
When standpipe riser is are separate

51
Before hooking up to the standpipe system, the FTC should be checked for what
Debris on the inside of the FDC
52
The order in which lines should be connected into the FDC Siamese
First line hooked to the left intake and charged, second line connected to the right intake
53
And a dry standpipe system the pumper will hook up to the system and will be what
The primary source of water
54
A wet standpipe system will draw water from that source until
A fire Department pumper increases its pressure to be greater than the water pressure from the source
55
His pump pressure is reduced in a standpipe system for any reason, what happens
The normal source supplies the system again, opening the check valve
56
Is extremely important that the siamese hook up the accomplished quickly so that

59
If an FTC is damaged and cannot be fed what can be done to supply the standpipe system
Water can be supplied to the system through the hose line outlet on the first floor
60
When bypassing the FDC using an interior outlet how should the standpipe feeding be prepared
Pressure reducing fittings removed, whenever possible 2 1/2 inch Siam is installed on the outlet with double female adapter so two supply lines can feed the system
61
When bypassing and FTC to feed a standpipe system in a wet system what should be done
Supply line to the outlet should be hooked up and charged before the outlet valve is opened
62
The best arrangement for supplying a standpipe system is to have a pump are positioned within what distance of the standpipe Siamese FDC

2 1/2 inch hose line
68
Do use of solid or nozzles should be considered for most fire attack with standpipes because
Because of their lower operating pressures
69
In large open areas firefighters must be prepared to use what for interior attack
