Ch 13. Water Shuttle Operations Flashcards
What is the primary purpose of relay pumping operations or tanker shuttle operations?
Relay pumping or tanker shuttle operations are the primary methods of providing water supply to points remote from a water source
What are some of the pros and cons of relay pumping?
Relay pumping usually provides a more reliable source of continuous water with the use of your apparatus, but it is more labor-intensive to take up when the incident is terminated
What is a safety concern of shuttle operations?
Shadow operations rely on the constant movement of apparatus at the fill in dumpsites as well as on the route between and two locations. This increases the chance of collisions.
Why are relay operations safer and shuttle operations?
Once relay pumping is set up, there are no moving pieces of apparatus.
What are the two primary types of apparatus is associated with Water Shuttle operations?
The two primary types of apparatus associated with water shuttle operations are water tenders and pumpers
 most water shuttles require at least two pumpers for water supply. These pumpers are designated the:
Fill site pumper -is responsible for the filling of water tenders
Dumpsite pumper- Operates near the fire scene, may also act as a attack pumper or it may relay water to the attack pumper
Per an FPA 1901, water tenders must be designed to be filled at a rate of at least ________ GPM.
1000 gpm
Although most water shuttles requires at least two pumpers for water supply, two exceptions may be:
Operations that feature a vacuum Tanker or the use of a hydrant
Each department must choose the appropriate capacity of the tenders based on the:
Local water supply availability and road conditions
Vehicle weight restrictions require that a water tender with a capacity greater than _________ gallons must have tandem rear axles, try axles, or semi trailers.
2000 gallons
Water tenders that are used only for shuttle operations do not require a _______ _________.
Fire pump
What is the pump capacity in GPM required on pumper/tenders?
Tenders featuring pumps of 750 GPM or greater rating are often called pumper/tenders
A 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. 
2000 gpm
22 feet
1750 gpm
Fire departments that used to convert other types of tank trucks to mobile water supply apparatus must meet:
NFPA 1901 standards for automotive fire apparatus
Apparatus that use medium diameter supply hose for filling should have at least ________ fill connections piped directly to the tank.
2 fill connections
Faster water shuttle operations are achieved by:
Efficient filling in dumping operations
If using a water tender with a top fill design, top tank fill and let’s should be placed:
So that the hose may be connected easily from the ground
Per NFPA 1901 Water tenders are required to be capable of dumping water from which sides?
From the left, right, and the rear of the apparatus
What two types of large tank discharges are in use on water tenders?
Gravity and jet assisted dumps
Where might the valve mechanism for a gravity dump valve be assigned for manual operation?
Discharge location on the sides or rear of the apparatus
Some fire departments have chosen to install larger gravity dumps underwater tenders instead of jet assisted dumps to:
Limit costs and address the operational issues concerning jet assisted dumps
When setting up a water shuttle, what is a very important part to the success of the shuttle operation?
It’s important to have the number of vehicles necessary to maintain a constant supply of water at the scene. 
What is a safety issue concerning water shuttles a narrow roads?
Vehicle tires may leave the road, creating potential for rollover
What affects might water shuttles face from steep grades?
It increases wear on apparatus
When establishing Water shuttle operation integrated into the incident command structure, it is recommended that the incident commander make designations that adhere to what command structure?
NIMS
Who is often responsible for water supply operations as assigned by the water supply group supervisor?
Company officers and or driver/operators
When operating from any hydrant during fill operations, Which discharges on the hydrant should be used?
All available hydrant discharges
In order to maximize the flow available while supplying a tender during drafting operations, the driver/operator should seek a position that requires a __________of lift. 
Minimum of lift
In cases where the static water supply is inaccessible to apparatus, what type of pumps may be employed to relay water to the fill sites pumper?
High-volume portable pumps
What should be continuously flowed in view of the driver/operator in order to help prevent loss of prime or overheating the pump during drafting operations?
A booster line or other small discharge
At the fill site, the water tender position should accommodate empty water tenders that need to line up and wait their turn to be filled, but if this arrangement becomes too congested preparation’s can be made to establish what?
Establish another water supply fill site
When an exact feel spot has been determined during Water shuttle operations, why should a cone or similar marker be placed adjacent to the driver operator door?
It denotes a stopping point for the tender that will allow the fill hose to be located near the rear of the apparatus
If an in-line gate valve is not available to use with LDH that connects to tenders at the fill site what maybe used between the last two sections to act as a valve?
LDH manifold
During fill operation why is it recommended that the fill site pumper remain in pump gear with a waste line flowing?
To prevent loss of prime and or overheating
When entering the fill site, how should the driver align the apparatus in relationship to the traffic cone or marking device?
So that the driver‘s door is parallel to the cone
During water shuttle fill operations, why is it advantageous for a second set of fill lines to be established from the fill site pumper if the fill site is large enough?
So a second tender can be positioned and connected to the lines while the first apparatus is filling
Water tenders pumping water from their tanks directly into the pump intake of an attack pumper is called a:
Direct pumping operation
A dumpsite that involves positioning a large water tender immediately adjacent to the attack pumper, and thus serving the same role as a portable tank, is called a:
Nurse tender operation
What should be located at the bottom of a tank to allow for movement of air at the top during rapid filling or unloading?
Tank baffles
At how many inches can a low level strainer allow for continuous drafting?
2 inches
When should multiple portable tanks be used?
When the incidents require a flow rate in excess of 300 GPM
What device is used to most efficiently transfer water between portable water tanks at dumpsite operations?
Jet siphon
What factors are used to determine the flow rate of a water shuttle under realistic conditions?
The complete round-trip circuit is timed from start to finish
Formulas developed by the insurance services office that evaluate tender performance divide water shuttle operations into two time elements that include:
Travel time and handling time
Water shuttle flow rate formula:
Flow = 0.9 x tank size
——————
Trip time
Travel time formula:
Travel time = 0.65 + (1.7) miles
- 0.65 and (1.7) are constants
Handling time formula:
Handling time = fill site time + dumpsite time
