ARFF DRIVER OPERATOR EXAM
QUESTIONS WITH CORRECT
ANSWERS
Identify THREE items commonly checked during the walk-around inspection of an
apparatus. - Answer- -Fuel tanks
-Wheels and tires
-Mounted equipment
All of the following statements about items you must make sure of prior to performing
the turret ground pattern test are TRUE EXCEPT: - Answer- The water tank must be at
least 1/2 full
If the solution temperature is higher than 70 add 0.1 minute for each 3 degree above 70.
If the solution temperature is lower than 70 subtract 0.1 minute for each 3 degree below
70 - Answer- Drainage time
If the solution temp is higher than 70 degrees, no correction applies. If the temperature
is lower than 70 degrees, add 0.1 unit of expansion for each 3 degrees below 70 -
Answer- Expansion ratio
Identify THREE items that are covered under a periodic inspection of a fire apparatus -
Answer- -Flushing pump and tank
-Cooling system hoses
-Power saws
If you are doing a maintenance check on items such as pump valves, fluid levels,
gauges, and batteries, you would document your findings on the: - Answer- Daily fire
apparatus records
The hand line nozzle test: - Answer- Analyses effect foam patterns produced from each
nozzle setting.
All of the following are equations used in the foam solution-concentration test EXCEPT:
- Answer- Rv
Identify THREE reasons for using inspection reports. - Answer- -Referrals
-Data References
-Replacement
, Place the steps for conducting the turret ground pattern test in the correct order. -
Answer- 1. Discharge the foam onto a paved surface for 30 seconds at the specific
pressure, in both the straight stream and fully dispersed nozzle settings.
2. Immediately after foam discharge has stopped, place markers, such as cones,
around the outside perimeter to preserve the identity of the foam pattern as it fell on the
ground.
3. For purposes of defining the edge of the pattern, disregard and foam that is less than
1/2 inch deep
4. Plot the distances between the markers on graph paper.
5. Measure the distance from the nozzle to the end of the effective foam pattern and
plot the results on graph paper.
Identify THREE reasons for using inspection reports - Answer- -Insurance
-Data References
-Replacement
All of the following statements about an ARFF apparatus are TRUE EXCEPT: - Answer-
There is a new technology that maintains a constant apparatus weight with either a full
or empty water/foam tank
Identify THREE conditions that could cause you to lose control of your ARFF Apparatus.
- Answer- -Liquid surge within the water tank
-Traveling at 50 mph around a turn
-Wet, icy roadways
A liquid surge effect is defined as: - Answer- the movement of liquid in an ARFF
apparatus due to changes in speed or direction.
Identify THREE TRUE statements about airfield light signals - Answer- -Light signals
are used in areas designed for aircraft use when radio communications fail
-A steady green light indicates that any aircraft or other apparatus may proceed
-An alternating green and red light indicates that traffic can proceed using extreme
caution
A runway distance remaining sign displaying the number "6" indicates to the pilot that
there are: - Answer- 6,000 feet of runway remaining
A painted or lighted "X" indicates that a runway is: - Answer- Closed to aircraft and
vehicle operations
To turn an ARFF apparatus: - Answer- Decelerate before the turn, turn, and then
accelerate.
When driving on a downgrade, what should your rpm gauge read? - Answer- Below
redline
