Chapter 13 - Water Shuttle Operations Flashcards
What is the optimum travel route for a water shuttle circuit on a significant grade?
A circular travel route with empty tenders traveling uphill
What do the “make and break” firefighters do?
Establish and remove connections between the water source and the tender
During portable tank operation, incidents that require a flow rate in excess of 300 gpm are best served by:
a multiple tank operation
There are _____ basic methods for calculating a flow rate for a specific tender
two
What is a self-supporting water tank?
A frameless tank consisting of a large bladder with a floating collar around the opening
A water shuttle operation must be integrated into the Incident Command structure, which should adhere to:
the National Incident Management System (NIMS).
Anyone assigned to the position of Water Supply Group Supervisor must have:
considerable experience in pumper, water supply, and shuttle operations.
In the formulas originally developed by the Insurance Services Office (ISO), what factor is built into the “travel time” formula?
Acceleration and deceleration times as the vehicle approaches the fill and dump sites
During a jet siphon operation, the pump’s prime will be lost if:
the apparatus tank is allowed to run dry.
What is an advantage provided by vacuum tenders?
A vacuum tender can self-fill from a static water source at a rate of up to 2,000 gpm
With the exception of operations that feature a vacuum tanker or the use of a hydrant, most water shuttles require at least _____ pumpers for water supply.
two
one at fill site, one at dump site
A method of calculating a flow rate for a specific tender rates the water supply performance of fire departments that protect rural areas and measures data by:
using a series of formulas originally developed by the Insurance Services Office (ISO).
At the fill site, _____ firefighter(s) should be assigned to maneuver and connect each fill line that is laid out.
one
Which action generally increases the safety of a gravity dump?
Installation of a remote dump valve
In accordance with NFPA® 1901, water tenders must be designed to be filled at a rate of at least:
1,000 gpm
On water tenders, remote controlled vents are preferable to manually operated vents because manually operated vents may require the driver/operator to:
climb on top of the tank.
At the fill site, how should the stopping point for the water tender driver/operator be denoted once the exact fill spot has been determined?
With a traffic cone or similar marker
Any portable tank, regardless of type, should be set up on a surface that is as level as possible and have a capacity at least _____ larger than the water tank on the apparatus that will supply it.
500 gallons
Direct pumping operations are typically accomplished by having the attack pumper lay out a supply line that is equipped with a _____________ in an area accessible to tenders.
gated or clappered Siamese
As with any drafting operation what should the dump site pumper do to ensure that prime is not lost when other discharges are shut down?
Flow a small waste line back into the tank
Ideally, the fill site pumper should be positioned so as to allow a view of both:
the water source and the water tender to be filled.
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.
90 percent
what is the best way to control flow from the fill site pumper?
Using the discharge gates on the pumping apparatus
What is the primary advantage of using a nurse tanker (tender) during dump site operations?
Capacity of its tank
Which may be one of the most hazardous tasks for the driver/operator during water shuttle operations?
Driving the travel route
Which dumping method is generally considered to be the simplest, quickest method to ensure a constant water supply for fire attack operations?
Portable water tank operations
What is the goal of a portable multi-tank operation?
Keep the tank from which the attack pumper is drafting full at all times
During dump site operations, the _____ 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 or unloading.
tank baffles
Which of the following maintains certain criteria for determining the proper specifications for water tender apparatus?
Each individual jurisdiction
When should an overhead pipe be used during water tender top-fill procedures?
When there is no other way of filling through the top opening
