The primary function of a fire department pumper on the fireground.
Provide water for firefighting operations.
When fire is evident there is a variety considerations in positioning the apparatus, what are some of the more important ones?
- Department SOP’s
- Rescue situations
- Water supply
- Method of attack
- Exposures
- Wind Direction
- Terrain
- Relocation potential
If a fire has the potential to grow or spread to exposures how should the apparatus be positioned?
So that it is not trapped by the advancing fire
If an apparatus arrives to a scene where no fire is evident (investigation mode), it is generally advisable to stop where?
The best access point into the occupancy, often the main entrance.
when using the front intake the apparatus should be at ____ degrees from the hydrant
45 degrees
how many lanes next to a incident on a roadway should be blocked?
at least one lane next to the incident

water vapor at 212 degrees
weight of a gal. of water?
8.33lbs per gallon
what is the primary way water extinguishes fire?
cooling, secondary smothers
when referring to friction loss what does first principle mean?
friction loss due to length of hose
when referring to friction loss what is second principle?
friction loss due to flow, gpm
when referring to friction loss what is third principle?
friction loss due to the diameter of the hose
4 fundamentals of every water system in terms of delivery
hydrants
distributers
secondary feeders
feeder
a centrifugal pump consists of what 2 parts?
an impeller, and a casing
what collects water, confines it and converts velocity to pressure
the pump casing
what is generally the rpms of the pump impeller?
2000-4000
3 main factors that influence the PDP?
- amount of water being discharged
- speed the impeller is turning
- pressure from the hydrant
what is the first indication that wear is becoming an issue on the pump?
when an increased rpm is required to pump the rated capacity.
what are some advantages to rear mount pumps
provides even weight distribution, allows more compartment space. but it also exposes the engineer to traffic

to avoid a vortex as water nears the pump what shape does the piping take
typically tapers to a square
why is it recommended to not pump with the drains open?
it can damage the O ring on the gasket that maintains an airtight connection
what is the purpose of a pressure governor, or pressure reliefs valve?
to reduce an accidental pressure surge on a discharge or hoseline.
