IFSTA Flashcards
Never ride on moving apparatus for any reason
true
most accidents occur at?
intersections
when more than one emergency vehicle is responding along same route, travel how far apart
300-500ft
what is total stopping distance?
Sum of braking and reaction distance
if building is more than 5 stories high, how should apparatus be parked?
Truck inside, engine outside.
Dual pumping?
one strong hydrant supplying 2 attack pumpers intake to intake.
Constant Flow nozzle?
designed to flow specific volume of water on all stream patterns at specific discharge pressure
Net Pump Discharge Pressure?
Difference between intake pressure and discharge pressure. aka actual amount of pressure being produced by the pump
what causes water hammer?
closing valves too quickly
if you have a 2 stage centrifugal pump and dont have enough pressure, what do you do?
set to pressure mode
most common cause of air leak during drafting?
An open drain or valve/cap
if when drafting and have gradual increase in vacuum, no change in flow rate, discharge gauge is fluttering up/down - what does it mean?
a blockage may be developing, cavitation - supply not adequate for flow
successful shuttle operation relies on?
constant movement of apparatus at fill and dump sites
relay pumping requires use of effective clear communication for success. what is the most accurate about this?
radios can be effective for this operation, but may be hampered by or create an excessive amount of radio traffic
when a pump fails to meet requirements for service testing, what issue may be investigated for one of the causes?
transmission in wrong gear
