Air brake test require that new apparatus be brought to a full stop in less than

35 ft

air brakes are required to hold the apparatus in place on a ____

20% grade

air pressure should be able to build within

60 sec.

air horn shouldnt operate with an air pressure lower than?

80 psi

apparatus inspections should be done in what order?

- on approach - Driverside door, cab - front insp. - passenger side - right rear - -rear - in cab - engine compartment

at a minimum what should be checked in the engine compatment?

- engine oil - engine air filter -emergency shut down - exhaust system - radiator coolant - cooling fan - washer fluid - battery condition - automatic trans fluid - power steering - air system - belts - leaks - elec. wiring - steering linkage - manual trans oil

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 converted to gas is called what, at what temp?

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

NFPA 1901 states pumpers with capacities greater than 500 gpm should be able to flow at least ____ gpm

500 gpm

tank to pump lines are generally ____ in.

4in.

in a centrifugal pump all intakes lines are generally below ____

the eye of the impeller, the only exception is tank to pump line

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.

when operating handlines and the intake pressure drops below____ psi the pump is in danger of cavitation.

20 psi

generally 1, 1000 gpm rated pumper should supply the FDC for every _____ sprinklers going off.

50 sprinklers
