D-O Pumper CDC CCRE QUESTIONS
AND ANSWERS GRADED A+
The lowest acceptable fuel gauge reading on a fire apparatus during inspection is: -
answerat least 3/4-full.
The rescue tool supply system equivalent of a junction box is called: - answera manifold
3 conditions where you should drive your fire apparatus in low gear: - answer1.
Approaching an intersection
2. Travelling around a corner
3. Climbing a hill
Three conditions to wearing your seat belt before an emergency vehicle moves: -
answer1. Providing patient care in the back of an ambulance.
2. Performing training for personnel learning to drive the tiller portion of a tractor draw
aerial apparatus.
3. Loading the hose back onto the fire apparatus.
if you are driving a fire apparatus that is longer than you are familiar with you must: -
answerAre more caution when judging clearance so you don't run up on curbs and
corners.
NFPA Standard 1002 requires that driver/operators operate a fire apparatus over a
predetermined route on a public roadway that incorporates all of the following EXCEPT :
- answerBoth a left and a right curve.
If a 3-inch hose is flowing 150 GPM, and a 2-inch hose is flowing at 150 GPM, which is
flowing at the higher velocity? - answerThe 2-inch is flowing at a higher velocity.
One of the principles of pressure says that the pressure on an amount of water... -
answer... is always perpendicular to any of any surface it acts on.
To raise the temperature of one lb. of water from 100F to 212F takes how many BTUs?
- answer112 BTUs
What are BTUs? - answerBritish Thermal Unit.
One BTU is equal to the amount of energy used to raise the temperature of one pound
of water one degree Fahrenheit. +1 degree Fahrenheit = 1 BTU.
, The master stream device that is often called a deck gun is the.. - answer...turret pipe
device.
BOUNCING water off the INSIDE WALL of the nozzle bore to create a fog pattern is
called? - answerPeriphery deflection
Periphery means side(like a wall is the side of a room)
Deflection means bounce.
A pumper has two 300-foot sections of a 3-inch hose with 2 1/2inch-couplings. They are
siamesed into 200 feet of 5-inch attack line.The attack line ends in a master stream with
a flow of 350 GPM. Given this hose layout, determine the total pressure loss for this
hose assembly. - answer44 PSI
"C" in the formula FL = C Q² L represents what? - answerHose Diameter Coefficient.
Determine the TPL for a hose assembly in which 400 feet of 5-inch hose is wyed into a
one 200-foot section of 2 1/2-inch hose and one 300-foot section of 2 1/2 inch hose.
Each attack hose is flowing at 200 GPM. - answer39 PSI
Most flowmeters in use have a design based on: - answera spring probe
(Note) A Municipal storm drain is not a water source - answer(Note) A Municipal storm
drain is not a water source
Name TWO correct statements about looping mains in a distribution grid. - answer1.
They create constant flow and less sediment forms in the pipes.
2. They ensure that water flows from two directions.
In a relay operation, relay pumpers must set their intake pressure relief valves (if
available) at: - answer10 psi ABOVE the discharge pressure of a previous pumper.
One of the assumptions of a maximum distance relay method is that: - answerThere is
20 PSI of residual pressure at each relay pumper.
State 2 characteristics of a forward lay. - answer1. A four-way hydrant valve is often
used with this lay.
2. Allows driver/operator to monitor the fire scene
1. fourway
2. d/o monitor fire scene.
State 3 characteristics of a reverse lay. - answer1. Forces the fire personnel to unload
equipment before hooking up to the hydrant.
2. Keeps pumper at the hydrant.
3. Pumper moves away from the fire incident to the hydrant
