Chapter 13 - Water Shuttle Operations

Question 1

In accordance with NFPA 1901, water tenders must be designed to be filled at a rate of at least _____ gpm so that pumpers assigned to the fill site must be rated at that capacity or greater.

Answer 1

1,000 gpm

Question 2

Tender featuring pumps of ____ gpm or greater rating are often called _______/______

Answer 2

750 gpm

Pumper/Tenders

Question 3

The vacuum tender is able to self-fill from a static water source at a rate of up to _____ gpm with a lift of up to ___ feet. These apparatus are also capable of discharging its water tank at a rate of up to _____ gpm.

Answer 3

2,000 gpm

1,750 gpm

Question 4

When possible, a water supply source capable of supply at least _____ gpm should be chosen in order to match NFPA recommended rate at which tenders should be filled.

Answer 4

1,000 gpm

Question 5

Driver/operators must consider the following safety issues when planing a route of travel for water shuttle operations. (7)

Answer 5

> Narrow Roads
> Long Driveways
> Blind curves and intersecitons
> Winding roads
> Steep grades
> Inclement weather conditions
> Freezing water

Question 6

The primary advantage of the ___________ is the large capacity of its tank that may allow incidents to be concluded before there is a need to refill the tank.

Answer 6

Nurse Tender

Question 7

NFPA 1901 requires all tenders to have the capability to dump a minimum average flow rate of _____ gpm for the first ___ percent of its tank capacity

Answer 7

1,000 gpm

90%

Question 8

Any tank, regardless of type, should be set up on a surface that is as level as possible and have a capacity at least ____ gallons larger than the water tank of the apparatus that will supply it.

Answer 8

500 gallons

Question 9

Formula for Water Shuttle Flow Rate

Answer 9

Flow = (0.9 x TS) ÷ Trip Time

Flow = Flow rate in gpm
TS = Tank size

Question 10

Formula for Travel Time

Answer 10

Travel Time = 0.65 + (1.7)(Distance)

Assuming avg speed of 35 mph
Travel time = Time in Minutes
Distance = Distance in Miles

Question 11

Formula for Handling Time

Answer 11

Handling Time = Fill Site Time + Dump Site Time

Time = make and break times + (TS ÷ Fill/Dump Rate)

Question 12

Formula for Tender Flow Rate

Answer 12

Flow = (0.9 x TS) ÷ (Travel Time + Handling Time)

TS = Tank Size

Question 13

Effective water shuttle operations are the result of ___ and _____ practices and not _____________.

Answer 13

Safe and Efficient

Excessive Driving Speeds
