IFSTA 3rd Edition Flashcards
Should you ever ride on a moving apparatus?
Never
Most accidents occur where?
Intersections
Multiple emergency vehicles responding along the same route, travel how far apart from each other?
300-500 feet
What is total stopping distance?
Sum of braking and reaction distance
If building is more than 5 stories high, how should apparatus be placed?
Truck inside
Engines outside
Dual pumping? What do you need?
Strong hydrant
Two attack engines (pumpers)
What is a constant flow fog nozzle?
Desingned to flow specific volume of water on all stream patterns at specific discharge pressure
Net Pump Discharge Pressure?
Diffrence between intake pressure and discharge pressure
What cause a water hammer?
Closing valves to quickly
If engine has 2 stage centrifugal pump and you don’t have enough pressure, what do you do?
Set to pressure mode
Most common cause of air leak during drafting?
Open drain or valve
If when drafting and have gradual increase in vacuum, no change in flowrate and discharge gauge is fluttering up and down. What does this mean?
Pump cavitation
Supply not adequate for flow .
(Pg 361 in book)
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 most accurate about this?
Radios can be effective for this operation, but may be hampered or create excessive volume or radio traffic
(Pg 434)
When pump fails to meet requirements for service testing, what issue may be investigated for one of the causes?
Transmission in wrong gear
