Water Shuttle Operations Flashcards
To increase shuttle efficiency firefighters should ________.
Maintain training on filling and dumping tenders
When considering a natural water supply for drafting which of the following would be a problem?
Shallow water (inadequate depth)
Wet or soft ground
Silt or debris laden water
Dumping the tender by pumping it out through a hose is more efficient than using the dump valve.
False
A dry hydrant for drafting is a hydrant that _______.
Is used to draft water from a static supply.
When using multiple tanks at a dump site the goal is to _______.
Keep the pool at the attack engine the fullest.
Direct pumping is performed when ______.
Minimal water is required.
When drafting the primer creates a lower pressure in the pump and intake hose to help move the water.
What external force pushes the water from the source up the intake hose?
Atmospheric pressure
Fill and dump sites should be planned to allow ________.
Continuous forward motion
This is the best way to avoid having to back up or turn a water tender…
A clear intersection with through access
When drafting from a portable water tank, the pumper should use a low level strainer to allow for continuous drafting to a point of about…
50mm (2 in)
When entering the fill site, where should driver’s line up the cone in relation to the vehicle for filling?
So that the driver’s side door is parallel to the cone.
When an exact fill site has been determined, why is a cone placed in adjacent to the driver’s door?
It denotes a stopping point for the tender that will allow the fill hose to be located at the rear of the apparatus.
A dump site 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
When setting up a water shuttle, what is most important to the success of a shuttle operation?
The number of vehicles necessary to maintain a constant supply of water at a scene.
Vehicle weight restrictions require that vehicles over ______ must be tandem axle.
8000 L
Although most water shuttles require at least two pumpers for water supply, what is the exception?
Operations that feature a vacuum tanker or the use of a hydrant.
Fill site pumpers operating from static water sources and dump site pumpers must be equipped with ______ and strainers in order to conduct drafting operations.
hard suction hose
What is a factor in overall tender performance?
the availability of personnel to operate the apparatus
If an inline gate valve is not available to use with an LDH that connects to the tenders at the fill site, it is possible to place an _______ between the last two sections as a valve.
LDH manifold
What can be said about using LDH hose filling operations?
Can be heavy and extremely difficult to handle.
Water tenders pumping water from their water tanks directly into the pump intake of an attack pumper is called a:
direct pumping operation
What must have an opening of sufficient size to allow free movement of water at the bottom of the tank and movement of air at the top during rapid filling and dumping operations?
tank baffles
