Pumping Apparatus Driver Operator
test 10 questions n answers rated A+
The priming action should continue until all air has been removed and: - ANS ✔a steady stream
of water discharges.
When connecting to the pump, incorrect positioning of the _____ may result in the formation of
an air pocket that can prevent effective drafting. - ANS ✔intake hose
The difference in elevation between the surface of the static water supply and center of the
pump intake is referred to as: - ANS ✔lift
Constant movement of water through the pump prevents: - ANS ✔overheating
Generally speaking, apparatus in good repair can draft water to a height of approximately: - ANS
✔20 feet (6 m).
During drafting operations, a hose with smaller diameter and greater length creates _____
friction loss. - ANS ✔higher
Which of the following artificial static water supply sources are usually found in areas NOT
serviced by a hydrant system? - ANS ✔Cistern
Each time nonpotable water is pumped through the apparatus, the pump and piping should be:
- ANS ✔flushed with fresh water as soon as possible.
, Fire departments are encouraged to use _____ to ensure access at drafting sites. - ANS
✔preincident planning
Which of the following situations could contribute to a pumper NOT being able to position itself
properly at a static water source? - ANS ✔High banks around the water source
In order for a pumper to approach its rated capacity using a traditional strainer, there must be
at least _____ of water over the strainer. - ANS ✔24 inches (600 mm)
Intake gauge readings below _____ indicates cavitation during drafting. - ANS ✔20 in Hg (70
kPa)
In general, the minimum amount of water around a barrel-type strainer is: - ANS ✔2 feet (600
mm).
The pump's capacity is determined in a given scenario by the diameter and length of the intake
hose, strainer design, and _____ lift. - ANS ✔vertical
When operating a draft, the most common blockage location is at the: - ANS ✔strainer
Artificial static water supply sources that resemble ponds or lakes may offer more accessibility
for fire apparatus than natural bodies of water because of their strategic area are known as: -
ANS ✔ground reservoirs.
When using a portable tank or swimming pool for drafting operations, a _____ strainer becomes
the appliance of choice. - ANS ✔low-level
To begin drafting operations, most of the air inside the pump evacuates, creating a: - ANS
✔pressure differential.
