1. If a fire department is considering purchasing a new mid-pumper chassis,
what factors related to its weight should they evaluate?
They should focus solely on the engine power, ignoring the weight.
They should evaluate the chassis weight in relation to the vehicle's
load capacity and the impact on maneuverability and braking
performance.
The weight should not influence their decision on purchasing
equipment.
They should only consider the weight for aesthetic reasons.
2. If a new fire apparatus fails to meet the NFPA 1901 brake test requirements,
what should be the immediate course of action before it can be used in
emergency situations?
The apparatus can be used as is, with caution.
The apparatus should undergo repairs and retesting to ensure it
meets safety standards.
The apparatus should be stored until further notice.
The apparatus should be used only for training purposes.
3. Describe the significance of the SAE number in the context of fire apparatus
maintenance.
The SAE number is significant because it helps ensure that the
correct oil viscosity is used, which is crucial for optimal engine
performance.
, The SAE number is significant because it indicates the type of fuel the
apparatus can use.
The SAE number is significant because it determines the weight
capacity of the fire apparatus.
The SAE number is significant because it specifies the maximum
pressure of the pump.
4. What is the recommended hand position for a driver when backing a fire
apparatus to the right?
Both hands at the 10 o'clock position.
Right hand at the 12 o'clock position and left hand at the 6 o'clock
position.
Both hands at the 2 o'clock position.
Left hand at the 12 o'clock position and right hand at the 6 o'clock
position.
5. During a brake test, an apparatus weighing more than 10,000 pounds (4540
kg) should stop within:
25 feet (7.5 m).
40 feet (12 m).
45 feet (13.5 m).
35 feet (10.5 m).
6. When setting up a water shuttle, which of the following is MOST important to
the success of the shuttle operation?
The type of equipment with which the jurisdiction and its mutual aid
agencies have experience
, The number of vehicles necessary to maintain a constant supply of
water at the scene
The ease of shutting down the operation after the incident has
concluded in comparison to relay operations
The total pressure loss due to elevation for any hoseline working on a
significant gradation
7. If a driver fails to maintain the correct hand position while backing a fire
apparatus to the right, what potential issue could arise?
Loss of control over the vehicle.
Enhanced communication with crew members.
Improved visibility of the surroundings.
Increased speed of the vehicle.
8. What is the method for setting the rpm of hydrant pumpers during pumping
operations?
By altering the pump size
By modifying the brake system
By adjusting the throttle
By changing the water source
9. Describe the significance of starting the engine in the context of fire
apparatus operations.
Starting the engine is irrelevant to pump operations.
Starting the engine is crucial as it powers the apparatus and enables
all operational systems to function.
Starting the engine is only necessary for testing the brakes.
, Starting the engine is optional if the apparatus is already warmed up.
10. What is the spiral, divergent chamber of a centrifugal pump in which the
velocity energy is given to water by the impeller blades and is converted
into pressure called? (p.299)
piston
impeller
eye
volute
11. What is the requirement for new apparatus according to the NFPA 1901 brake
test?
The apparatus must come to a complete stop within a specified
distance.
The apparatus must not exceed 30 mph.
The apparatus must stop within 10 seconds.
The apparatus must reduce speed by 50%.
12. If an attack pumper is incorrectly set to standby mode during an emergency
response, what impact might this have on firefighting efforts?
Improved communication
Enhanced maneuverability
Delayed water delivery
Increased fuel efficiency
13. Select the pump component that is a widening spiral channel.
