Flashcards in Chapter 14 Water Shuttle Operations Deck (60)
Which type of apparatus are positioned at the water supply source and used to fill empty water tenders?
Fill site pumpers
Pumpers must have a minimum pump capacity of ___ to conform to NFPA® 1901.
1,000 gpm (4 000 L/min)
Which of the following are considered the backbone of any water shuttle operation?
Which of the following apparatus are the most efficient for use in water shuttle operations?
B. Tenders with no fire pumps
C. Tenders with water tanks with less than 2,500 gallons (10 000 L) and rapid unloading capabilities*
D. Tenders with water tanks with more than 2,500 gallons (10 000 L) and rapid unloading capabilities
Vacuum tankers are self-filling from a static water source at a rate of up to ___ gpm (L/min) with lift capability of up to ___ feet (m).
2,000 gpm (8 000 L); 22 feet (6.7 m)
Most water tenders carry from ___ to ___ gallons (L) of water.
1,500 to 3,000 gallons (6 000 to 12 000 L)
Water tenders must have a tank-to-pump line capable of supplying the pump with 500 gpm (2 000 L/min) until at least ___ of the tank is empty.
Water tenders must be equipped with at least one external connection to allow filling at a minimum rate of:
1,000 gpm (4 000 L).
Water tenders must have a discharge capable of emptying ___ of the tank volume at an average rate of 1,000 gpm (4 000 L/min).
Water tenders must have a pump-to-tank fill line that is at least:
2 inches in diameter.
In cases of a narrow lane, driveway, or dead-end street, it may be advantageous to locate the dump site:
at the nearest intersection to the incident scene.
Who should select the closest suitable water supply to the scene?
The Incident Commander or water supply group supervisor
The best fill and dump sites are those in which the water tenders:
drive straight in from one direction, fill or dump, then proceed straight out.
The route of travel selected for a shuttle operation should reflect:
both safety and operational efficiency.
A(n) ___ route of travel is considered to be the optimum arrangement for conducting a water shuttle operation.
At fill sites adjacent to roadways that have not been closed to public traffic, water tenders should be positioned:
off the roadway.
On fire incidents, the ___ may choose to establish a water supply branch or group that includes the water shuttle operation.
When the water supply group is established, the person in charge is known as the:
Water Supply Group Supervisor.
Which members of the water supply branch or group can communicate directly with command?
Only the supervisor
When two or more water shuttles are required, the IC may decide to establish a water supply branch, with the supervisor being called the:
Water Supply Branch Director.
Water supplies for a shuttle operation come:
from either a fire hydrant or a static water supply source.
IFSTA recommends that ___ be used to fill tenders at all fill site operations.
Who must determine the best position for drafting or hydrant connection?
Ideally, the pump panel should be located so that the driver/operator can view:
both the fill and source operations.
When positioning at a hydrant, the driver/operator should connect, at a minimum:
a large diameter intake hose between the large pump intake and the steamer connection on the hydrant.
If a static water supply source is completely inaccessible to pumpers, two or more high-volume portable pumps may be used to relay water to the fill site pumper, if there is less than ___ feet (m) between the source and the pumper.
100 feet (30 m)
Regardless of whether a hydrant or static source is used, a ___ that is within view of the driver/operator should be continuously flowed from the fill site pumper to prevent a loss of prime.
booster line or some other type of small discharge line
Although hoses used to fill tenders vary, the most common and most efficient are:
two 2½-inch (65 mm) direct tank fill connections or one LDH direct tank fill connection on the rear of the vehicle.
The ideal fill position is one that:
allows the driver/operator to enter and exit the fill site without turning around or backing up.
