Arrive and layout LDH
First Tanker Shuttle Op
Arrive in close proximity to attack Engine
Connect LDH to first engine
Drop Siamese behind tanker
Second Engine Shuttle Op
Nurses Tanker
Establish the Dump Site
Second Tanker Shuttle

Join water shuttle
Drop RWS equipment if necessary
Third Engine Shuttle
Assume Role of DSUL and WGS until relieved by chief
Dump water into system
Use crew for dump site
Fourth Engine Shuttle
Crew minus driver become RIT
Drop water into tanker at dump site and become part of shuttle
Fifth Engine Shuttle
Supply water into system when no tankers
Establish Fill site with two fill stations
FSUL assume
Additional app on first alarm
Report to incident scene
Dump personnel
Move to staging
First Tanker
Less than 200
200-1000ft
Over 1000ft
Establish Dump Site, connect LDH to first engine, assume direct fill Tanker
Proceed with engine to incident
Refer to preplan
Second Engine

Transfer water to tanker or to Siamese
Become part of the shuttle operation
Layout from the dump site to the first tanker
Preplan
Second tanker
200
200 1000
1000
Transfer water to first tanker
Connect to 2nd engine siamese
Serve as a direct fill tanker
Preplan
Make sure to set up mulitple lines to tankers intakes
Third Engine

Dump Site Unit Leader
Driver transfers water to the tanker
Engine Joins the shuttle
Fourth Engine Direct Fill
RIT
Driver transfers water and becomes part of the shuttle
Fifth Engine Direct Fill
Fill Site Unit Leader
Fill site ops
2 lines to fill units.
Relay ops are feasable at distances greater than
1 mile
Fire boats can be used as a drafting unit to supply a relay TRUE OR FALSE
True
Dry hydrants should be backflushed and tested every
6 months and prior to use
Storage Tanks should be tested every
Six months
Typical sizes of dump tanks
1500gal 10,3 x 30
2100gal 11,3 x 30
2500gal 12,3 x 30
3000gal 13,3 x 30
*memorize gallonage bc size of tanks are the same dimension except 10-13 increases by one
Low level suction strainer use, flow and restriction
Use in dump tank
2 inch water level
750 Gpm
Low profile jet siphon strainer use and flow
Allow engines to get water without drafting by charging a 1 3/4 hoseline to it
500 gpms
Jet siphon use and flow
Move water between dump tanks
800 GPM flow
Turbo Draft Use and connections
Allows a unit to access a water supply that would normally be out if reach for hard suction
2.5 or 3 inch conn
Automatic Air Primer
Air used from the air tanks of the engine to automatically prime whenever the discharge pressure drops below 20 psi
Rule of thumb for deciding on whether to use a relay or shuttle
If the distance to the water source is greater than a 3 pumper relay, use the shuttle
All incoming tankers will supply the clappered siamese from the engine at ______psi
70
Fill site ops
Fill tankers at a minimum rate of
1000 gpms at 100 psi one at a time
REEU
Rapid
Efficient
Expandable
Uninterrupted
What is considered a rural water supply
2000 feet from Hydrant access
