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 12
MOTIVATION: One important activity on the fireground is the ability to move water from the source to where it is needed. All the water in the world will not control or extinguish a fire if it cannot be moved quickly and efficiently. In areas without a pressurized water system, this becomes more critical.
OBJECTIVE (SPO): The firefighter will demonstrate a working knowledge of supplying water to the fireground and, by participation and observation, the various appliances, hose layouts, and procedures involved in supplying water at an emergency scene.
ESTABLISHING SUPPLY LINES
* Supply line evolutions
* Supplying water from various sources
ESTABLISHING SUPPLY LINES
SPO The firefighter will demonstrate a working knowledge of supplying water to the fireground and, by participation and observation, the various appliances, hose layouts, and procedures involved in supplying water at an emergency scene.
EO 1-1 Describe the various hose evolutions used to supply water to the fireground.
EO 1-2 Demonstrate supplying water for fireground operations from various sources.
The purpose of this drill is to review and build on basic skills with the emphasis on improving efficiency and teamwork. It is assumed that the participants have some basic knowledge of the subject matter. The focus of the drill should include personal and team safety. The drill should include minimal instruction and maximum skills practice. The drill should also be conducted with the normal staffing that would respond on an engine on a structure assignment.
I. SUPPLY LINE EVOLUTIONS (1-1)
A. Straight Lay
1. Supply line is laid from the water source to the emergency scene
2. If threaded couplings are used, a female connection is needed if the hose is to be connected to a
3. Hydrant valve may be connected to end of supply hose and connected to the hydrant
B. Reverse Lay
1. Supply line is laid from the scene to the water source
2. If threaded couplings are used, a male connection is needed to connect to a siamese for a
standpipe or sprinkler system or another engine at the scene
3. If the engine is laying hose to a hydrant, a soft sleeve, hard sleeve, or section of supply line can
be used to connect to the hydrant
4. If water is being taken from a static source, it will require setting up for draft
C. Split Hose Lays
1. Combination of a forward lay and a reverse lay
2. Utilizes two pumpers to complete
3. May require a double female or a double male to connect, dependent on how the supply line is
loaded on the engine and the couplings at the end of each hose
D. Review Various Hose Lays and Means of Obtaining Water
1. Laying a single supply line from the hydrant to the scene
a. Remove the amount of hose necessary to reach hydrant along with any adapters and a
b. Once the hose is secured against the hydrant, signal the apparatus driver that it is safe to move
c. Connect to the hydrant using the 4-1/2-inch steamer connection (LDH) or one of the
2-1/2-inch connections (2-1/2-inch or 3-inch)
d. If a hydrant valve is to be used, connect the hydrant valve to the steamer connection
e. Open the hydrant completely and back off one-half turn
