most accidents occur at?

A

intersections

3
Q

when more than one emergency vehicle is responding along same route, travel how far apart

A

300-500ft

4
Q

what is total stopping distance?

A

Sum of braking and reaction distance

5
Q

if building is more than 5 stories high, how should apparatus be parked?

A

Truck inside, engine outside.

6
Q

Dual pumping?

A

one strong hydrant supplying 2 attack pumpers intake to intake.

7
Q

Constant Flow nozzle?

A

designed to flow specific volume of water on all stream patterns at specific discharge pressure

8
Q

Net Pump Discharge Pressure?

A

Difference between intake pressure and discharge pressure. aka actual amount of pressure being produced by the pump

9
Q

what causes water hammer?

A

closing valves too quickly

10
Q

if you have a 2 stage centrifugal pump and dont have enough pressure, what do you do?

A

set to pressure mode

11
Q

most common cause of air leak during drafting?

A

An open drain or valve/cap

12
Q

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

a blockage may be developing, cavitation - supply not adequate for flow

13
Q

successful shuttle operation relies on?

A

constant movement of apparatus at fill and dump sites

14
Q

relay pumping requires use of effective clear communication for success. what is the most accurate about this?

A

radios can be effective for this operation, but may be hampered by or create an excessive amount of radio traffic

15
Q

when a pump fails to meet requirements for service testing, what issue may be investigated for one of the causes?

A

transmission in wrong gear

16
Q

relay vs shuttle operation

A

shuttle operation increases likelihood for collision
