c. requires that framework be assembled at the scene and the liner attached to the inside.
d. folds and is mounted and removed from the apparatus, as with a ground ladder
apparatus, as with a ground ladder.
d. folds and is mounted and removed from the apparatus, as with a ground ladder
Which of the following statements BEST identifies when an overhead pipe should be used during water tender top-fill procedures?
a. When an abundance of water tenders is available, because it takes more time
b. When there is no other way of filling through the top opening
c. When a limited number of water tenders are available, because it is faster
d. When a pumper is not available to draft from the site and pump directly into the tender
b. When there is no other way of filling through the top opening
Ideally, the fill site pumper should be positioned so as to allow a view of both:
a. the driver/operator and the firefighter maneuvering the fill line.
b. the approach and departure routes.
c. the hydrant and the portable pumps.
d. the water source and the water tender to be filled.
d. the water source and the water tender to be filled
Which of the following is the
BEST way to control flow from the fill site pumper?
a. By using the discharge gates on the pumping apparatus
b. By shutting down the fill site pumper
c. By using a manifold between the last two sections of hose to act as a valve
d. By closing the direct tank fill valve on the tender
a. By using the discharge gates on the pumping apparatus
Which of the following is an advantage provided by vacuum tenders?
a. A vacuum tender connects to pumpers at the fill site faster than standard water tenders.
b. A vacuum tender is more maneuverable and therefore reduces travel time.
c. A vacuum tender can self-fill from a static water source at a rate of up to 2,000 gpm (8 000 L/min).
d. A vacuum tender uses a small diameter supply hose with two external fill connections.
c. A vacuum tender can self-fill from a static water source at a rate of up to 2,000 gpm (8 000 L/min)
Which of the following BEST exemplifies a problem that steep grades can cause during a water shuttle operation?
a. Water is more likely to spill from apparatus during shuttle operations on a steep grade.
b. Uphill grades slow the operation down, and downhill grades require constant attention to control the vehicle.
c. Shuttles cannot be filled as fully in order to prevent overflow during shuttle operation.
d. Uphill grades require constant attention to vehicle speed control, and downhill grades slow the operation.
b. Uphill grades slow the operation down, and downhill grades require constant attention to control the vehicle.
Which dumping method is generally considered to be the simplest, quickest method to ensure a constant water supply for fire attack operations?
a. Attack pumper operations
b. Nurse tender operations
c. Portable water tank operations
d. Direct pumping operations
c. Portable water tank operations
Direct pumping operations are typically accomplished by having the attack pumper lay out a supply line that is equipped with a(an) _______ in an area accessible to tenders.
a. gated or clappered Siamese
b. portable tank
c. baffle
d. Open butt (lol)
a. gated or clappered Siamese
The Insurance Services Office (ISO) formula uses _________ of a tender’s total tank capacity to account for water lost or undischarged and remaining in the tank after the dump valve is closed.
a. 66 percent
b. 50 percent
c. 90 percent
d. 70 percent
c. 90 percent
