Chapter 18 Flashcards
Stabilizers should always be raised following the reverse order by which they were deployed because:
a. doing so will require less hydraulic power to retract the stabilizers.
b. doing so will cause less strain on potentially unstable terrain.
c. it is the easiest method for the driver/operator to remember.
d. it avoids undue stress on any component of the apparatus.
d. it avoids undue stress on any component of the apparatus.
The driver/operator should never position a tractor-drawn aerial apparatus with the tractor and trailer at an angle greater than 90 degrees because:
a. damage to the truck may occur.
b. it requires more space than is usually available.
c. it requires a great amount of fuel to operate in that position.
d. such a position limits the maximum reach of the aerial device.
a. damage to the truck may occur.
Which of the following is the primary difference between box stabilizers and fulcrum-type stabilizers?
a. Fulcrum-type stabilizers can be deployed in any position with minimal space.
b. Fulcrum-type stabilizers cannot support an apparatus without another type of stabilizer for support.
c. Fulcrum-type stabilizers can only be deployed in a short-jacked position.
d. Fulcrum-type stabilizers can only be deployed in the fully extended position.
d. Fulcrum-type stabilizers can only be deployed in the fully extended position.
Manual stabilizers are most likely to be found on;
a. older midship and tractor-drawn aerials.
b. modern aerial ladders and elevating platform aerials.
c. older water towers and elevating platform aerials.
d. modern midship and tractor-drawn aerials.
a. older midship and tractor-drawn aerials.
After the apparatus is stabilized laterally on uneven terrain, it is preferable to operate the aerial device over the:
a. uphill side of the apparatus.
b. back of the apparatus.
c. downhill side of the apparatus.
d. front of the apparatus.
a. uphill side of the apparatus.
When the fire pump is already activated and in use, the driver/operator must notify personnel on handlines and other nozzles when they are activating the hydraulic system because:
a. this action will stop the water supply to any nozzles or handlines.
b. this action will increase the water supply to the nozzles.
c. this action may affect the water supply in an unpredictable way.
d. this action will lower the water supply to the nozzles.
d. this action will lower the water supply to the nozzles.
Which of the following is a way to minimize stresses on the aerial device when positioning an apparatus on a longitudinal grade?
a. Using the stabilizers to level the apparatus as much as possible
b. Operating articulating aerial devices off of the front of the vehicle
c. Placing the apparatus crosswise on the grade
d. Operating the aerial device directly over either side of the apparatus
a. Using the stabilizers to level the apparatus as much as possible
Which of the following prevents the movement of fluid within the stabilization
system?
a. Holding valves
b. Stabilizers
c. Selector valve
d. Interlock
a. Holding valves
