one and half times
p138
The ________ of a structure are generally considered the safest position should a collapse occur.
corners
p138
Depending on the incident, apparatus, equipment, and personnel operating within ______ feet of the base of a high-rise fire may need to be protected from falling glass and debris.
200 feet
p139
If a building is less than _____ floors tall, the _______ _______ should be positioned on the side of the street closest to the building and aerial apparatus are placed outboard of the pumpers.
5 floors / attack pumper
p140
If a fire building is greater than five floors tall how should attack pumpers and aerial apparatus be positioned?
the attack pumper takes the outside position to allow the aerial apparatus maximum reach to the building.
p140
In order to supply a fire department connection most efficiently, a pumper should position as closely as possible to the _______ _______.
water source
- Point at which the fire department can connect into a sprinkler or standpipe to boost the water pressure and flow in the system.
Fire Department Connection (FDC)
p141
- To shuttle water between a source and an emergency scene using mobile water supply apparatus.
Relay
p141
- Process of acquiring water from a static source and transferring it into a pump that is above the sources level; atmospheric pressure on the water surface forces the water into the pump where a partial vacuum was created.
Drafting
p141
- Supply of water at rest that does not provide a pressure head for fire suppression but may be employed as a suction source for fire pumps; for example, water in a reservoir, pond, or cistern.
Static Water Supply
p141
Preference should be given to drafting locations that are accessible from a hard _________ and require a minimum length of hard _______ ______ or _______.
surface / intake hose / lift
p142
A _____ ________ consists of an intake hose connection on the shore and a length of pipe extended into the water with a strainer on the end.
dry hydrant
p142
- Permanently installed pipe that has pumper suction connections installed static water sources to speed drafting operations.
Dry Hydrant
p142
Only hard intake hose that has been designated to withstand _________ _________ should be connected to a fire hydrant.
positive pressure
p 143
The procedures for many fire departments require that d/o place ______ _______ on the small diameter discharges of dry barrel hydrants before connecting to the large diameter discharge.
gate valves
p 143
- Hose used to connect a fire department pumper or a portable pump to a nearby water source; may be soft sleeve or hard suction hose.
Intake Hose
p 143
The preferred type of hose for hydrant connection is?
large diameter intake hose
p 143
Large diameter intake hose is common in _____ foot lengths. Shorter sections of ____ to _____ feet are also available for use when the pumper is in close proximity to a hydrant.
100 foot / 10 to 50 feet
p 143
Stopping short of the hydrant allows the intake hose to ?
curve slightly, preventing kinks that can drastically restrict flow
p 144
A good way to minimize the chance of the intake hose kinking is to put a _______________ ________ in the hose when making the connection between the hydrant and pumper.
counterclockwise twist
p 144
- Operation where a strong hydrant is used to supply two pumpers by connecting the pumpers intake-to-intake. The second pumper receives the excess water not being pumped by the first pumper, which is directly connected to the water supply source.
Dual Pumping
p 144
- Short relay operation in which the pumper taking water from the supply source pumps into the intake of the second pumper; the second pumper then boosts the pressure of the water even higher. This method is used when pressures higher than the capability of a single pump are required.
Tandem Pumping
p 144
A tandem pumping operation may be required when it is necessary to supply a ?
high-rise sprinkler or standpipe system
p 144
In tandem pumping operations apparatus may be located up to ______ feet apart.
300 feet
p 145
Relay pumping is generally used to increase the ________ of _______ available at a fire scene, while tandem pumping (another form of relay) is most often undertaken to increase _______ __________.
volume of water / water pressure
p 146
A tandem pumping operation may be capable of pumping water at a ________ __________ than fire hose and adapters can withstand.
greater pressure
p 146
Which NFPA standard contains test pressures for various types of fire hose?
NFPA 1962, Standard for the Inspection, Care, and Use of Fire Hose, Couplings, Nozzles, and the Service Testing of Fire Hose
p 146
Due to the dynamic nature of wildfires, apparatus are seldom positioned in the ?
same location for the duration of an incident
p 146
