The process of raising water from a static source to supply a pumper
drafting
Previously, battalion chiefs knew all available water sources in their districts and
captains in their response areas. They were known as
Pumper chances
During drafting operations, there is generally an elevation difference
between the static water source and the center of the pump. This
elevation difference is known as
Lift
Theoretically, at sea level a pump can lift water
33.8 feet (14.7 psi multiplied by 2.3 ft/psi)
For every 1,000 feet of altitude,
atmospheric pressure decreases by about
.5psi
The maximum height to which water can be drafted is closer to ___ feet, as opposed to the theoretical lift of 33.8 feet.
20- 25
At 20 feet of lift, the amount of water that can be supplied is only about ___ percent of the rated capacity of the pump.
60
The chosen site should allow ___-inches of water
completely around the strainer.
24
When drafting with a midship pump at a boat ramp it is best to ____ the ramp
back down
_____ shall be worn by all members working around a water source
Life jackets
Check hard suction hose___ to make sure that they are in good
condition and free of debris
gaskets
A _____may be used to tighten hard suction connection
rubber mallet
Immerse intake strainer at least ___below water to prevent pump
from drawing air
two feet
If drafting in less than two feet of water, a _____ may be
placed above the strainer to prevent the whirlpool effect
capped bottle or other buoyant object
As a general rule, keep the transfer valve in ____
position when pumping up to two thirds of the rated capacity of the
pump, and in ____when pumping more than two thirds the
rated capacity
pressure (series), volume (parallel)
If the priming pump does not prime the
main pump and discharge a steady stream of water within __seconds
(1250 GPM pump or smaller) or __ seconds (1500 GPM pump or larger),
30, 45
Operating the priming pump continuously for more than __ minute may damage the electric motor
one
Once you have achieved a prime do not operate the main pump without
____
flowing water
The maximum amount of vacuum that most
pumps develop is approximately ____
22-inches of mercury
When the pump has been successfully primed, increase the setting of the
throttle before attempting to open any of the discharges. Increasing the
setting of the throttle is needed to boost the pressure between____
psi.
50 and 100
The ____ will assign the responsibility of coordinating the Bureau’s Wildland Program to a
Battalion Chief.
Division Chief of Emergency Operations
The general membership will be trained and ready to safely respond to the small grassfires within PF&R’s jurisdiction. Further wildland training will be determined by the ____ and the assigned Battalion Chief
Wildland Steering Committee
The Wildland Team consists of PF&R members with advanced wildland training for the
purpose of ____
urban interface structure protection
Currently the Wildland Team consists of approximately ___ members from the
ranks of firefighter through Battalion Chief
100
