Back To Basics: Establishing Supply Lines
TOPIC: BACK TO BASICS: ESTABLISHING SUPPLY LINES TIME REQUIRED: THREE HOURS MATERIALS: TWO FULLY EQUIPPED PUMPERS, STATIC AND PRESSURIZED WATER SOURCES REFERENCES: ESSENTIALS OF FIRE FIGHTING, FOURTH EDITION, IFSTA, CHAPTERS 11 AND...
b. Drafting involves the use of one or more sections of hard sleeve and some type of strainer
device on the end of the hard sleeve
c. The hard sleeve(s) should be connected and all connections are made air tight using a rubber
mallet
d. A strainer should be placed on the end of the hard sleeve that is to be placed in the water
source (a low level strainer may be used with a portable tank) to prevent debris from
damaging the pump
e. The female connection on the hard sleeve should be connected to one of the steamer
connections on the pumper (preferably one on either side of the pump rather than a front or
rear intake)
f. A rope should be attached to the strainer for later retrieval as well as to assist in keeping the
strainer off the bottom of a pond, lake, or stream bed
g. If large quantities of water are needed and pumper capacity is insufficient, more than one
pumper may be used at the water source with the water being pumped into a Siamese or
gated Siamese
7. Water relay
a. Involves the use of multiple pumpers to move water longer distances
b. Begins at the water source with the supply pumper setting up at a hydrant or static source
c. As each pumper to participate in the relay arrives, they begin laying hose from the supply
pumper to the scene
d. Each pumper participating in the relay should not generally lay more than 1,000 feet of hose
to keep engine pressure down (lesser friction loss to overcome)
e. The last pumper in the relay will supply water to the attack pumper
f. Flow of water starts with the supply pumper
g. Manifolds, water thiefs, or gated wyes may be used at the scene to provide water to more
than one attack pumper
8. Rural operation with nurse tanker or portable tank
a. Lay LDH, either 4-inch or 5-inch, from end of lane back to fire scene
b. Manifold or wye used to distribute water at scene
c. LDH supplied from portable tanks or nurse tanker
d. Reduces need for extra apparatus at scene when not needed
e. Provides mobility for moving water during shuttling operations
II. SUPPLYING WATER FROM VARIOUS SOURCES (1-2)
A. The student will perform the following evolutions using as many of the appliances described above
as possible. There are other evolutions that could be considered depending on local need and
capability.
1. Lay a supply line from a hydrant using LDH and hydrant valve, connect the hydrant valve to the
hydrant, charge the supply line, connect another engine to the hydrant, and have the supply
engine supply the attack engine through the hydrant valve.
2. Reverse lay from engine or Siamese to source and set up water supply from a pressurized
source.
3. Using the reverse lay, set up water supply from a static source using LDH, to supply a second
engine at the scene.
4. Using the split lay, set up water supply from a pressurized source using a single line to supply a
second engine at the scene.
5. Set up water supply from a portable tank using multiple engines. The evolution should include
one engine operating as the attack unit and another engine operating as the supply unit at the
portable tank. One of the units will be required to set up the portable tank which can be filled
