one engine
one commander

4 1/2 inch to 6 inch double female
6 inch double female
Drafting pits
AKA dump tanks
1500-3000gpm
Low level suction strainer
Used in dump tanks
can be used in 2 inches of water
Max flow 750 gallons per minute
Low profile jet siphon strainer
Allows engine to get water from dump tank without drafting
utilizes Venturi affect
minimum flow 500 GPM
jet siphon
moves water between dump tanks 800 GPM flow rate
utilizes Venturi affect
First engine nursing ops direct fill role and responsibility
Less than 200’ - lays out supply line and acts as attack engine
200’-1000’ - proceeds directly to incident and begins attack
2nd engine will layout
First tanker nursing ops direct fill role and responsibility
Less than 200’ - position at dumpsite serve as dumpsite tanker
200’ - 1000’ positions near first engine. connects to lay out and supplies first engine
Second engine nursing ops
direct fill role and responsibility
Less than 200’ - transfer water to first tanker at dumpsite join shuttle if needed
200’ - 1000’ - lays out supply line from
dumpsite to first tanker
Second tanker nursing ops direct fill role and responsibility
Less than 200’ - transfer water to first tanker at fill site join shuttle if needed
200’ - 1000’ dumpsite tanker
Third engine nursing ops direct fill role and responsibility
less than 200’ - positions with 1st tanker and assists
200’-1000’ - dumps water joins shuttle
Fourth engine nursing ops direct fill role and responsibility
Dump water at dumpsite join shuttle
Fifth engine nursing ups direct fill role and responsibility
fill site operations
minimum two lines
Goals of rural water supply operations
Rapid- deployment
efficient- movement of water expandable - water supply
uninterrupted/ flow of water
Define direct fill operation
nursing operation providing immediate water to the fire ground eliminating needs for portable thumbtacks
short driveways less than 200 feet the second tanker will transfer water from to first tanker and then become part of the shuttle operation
Long driveways long more than 200 feet the second tanker will position to receive water from the Shuttle operation. first tanker proceeds to the structure with first arriving engine
Define nursing operation
Procedure during initial fire attack used in place of dumpsite first arriving engine and tanker position at fire location for attack additional tanker establishes dumpsite supplying water to attack apparatus
Define nurse tanker
Tanker which proceeds with the initial attack engine to the incident and provides water as needed at attack
Define relay operations
Uses three or fewer engines to supply the attack engine directly from the water source to the supply line
What distance in feet should I relay operation not exceed
3000’
Define shuttle operation
The procedure of using engines and tankers remove water from a full site to the incident scene
What is the nova recommendation for a tanker size
1000 gpm
2000 gallon tank
What is the calculation for determining tanker flow
tank capacity - 20%
