Rural water Flashcards
The goals of rural water supply operations are to be:
▪ Rapid (quickly deployed, supporting the initial attack).
▪ Efficient (providing maximum GPM/fire flow based on available water).
▪ Expandable (enabling the water supply to increase as needed).
▪ Uninterrupted (providing a continuous flow for the duration of the fire).
The movement of water at fires will almost always consist of one of three types of operations:
nursing operations, relay operations, or shuttle operations
Who assumes control of the dumpsite?
3rd engine
Who assumes Dumpsite unit leader?
3rd engine OIC
Who establishes the water supply group?
2nd arriving command officer (initially 3rd engine until command arrival)
Tanker Task Force
Three tankers, one engine, and one command officer.
Minimum tanker specs
minimum 1000-GPM pump and a 2,000-gallon water tank.
The procedure of using engines and tankers to move water from a fill site
to the incident scene.
shuttle operation
Generally, this procedure uses three or fewer engines to supply the attack
engine(s) directly from the water source through a supply line that should not exceed 3000 feet from the incident.
Relay operations
A tanker that proceeds with the initial attack engine to the incident scene and
provides water as needed for the initial attack.
Nurse tanker
Includes all known locations where hydrants are more than 2,000 feet from a
given structure.
non hydrant area
How many lines will come from the fifth engine at the field site to facilitate rapid filling?
at least 2
The driver and engine of the third and fourth engine become part of what?
shuttle operation
Who assumes the role of fill site unit leader?
5th engine OIC
What should be requested for water supply operations?
An alternate channel
Fill site engines with electronic governor controls need to always draft and fill in ______ mode
RPM mode, pressure mode can cause damage to tanks!
Tanker flow calculation
Total Capacity of Tanker minus 20% divided by the round-trip time.
An agreement with owners of preplanned water sources
water usage agreement
If the dump site is less than________ feet away from incident, the first due engine will lay in or hand jack hose back to dump site.
200 ft
First tanker should drop their_________ at the dump site before proceeding to the first engine’s location.
4-inch siamese valve
Relay operations with 4 inch hose are feasible at distances over_____
1 mile
_______can be used as a drafting unit to supply a relay, supplement an established water supply, or supply a fill site for a shuttle operation.
Fire boats
Dry hydrants should be back flowed and tested every________
6 months
All units need a 4.5 to 6 inches double female NPT bell adapter and a 6 inch double female to draft from a dry hydrant
