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...


             it to the intake on the pump panel

      2. Laying dual lines of 2-1/2-inch or 3-inch supply line from the hydrant to the scene

          a. Remove the amount of hose necessary to reach the hydrant along with any adapters and a

             hydrant wrench

          b. Once the hose is secured against the hydrant, signal the apparatus driver that it is safe to move

              the engine

          c. Connect to the hydrant using the two 2-1/2-inch hydrant connections

          d. If a hydrant valve is to be used for one of the lines, connect the hydrant valve to the steamer

              connection and the other line to one of the 2-1/2-inch connections

           e. Open the hydrant completely and back off one-half turn

           f. If a supply engine is to be used, connect the supply lines to the supply engine

           g. At the scene, the driver or other designated person will disconnect the supply lines and

              connect them to the intake on the pump panel

      3. Laying a single LDH line from the scene to the water source

           a. Remove the coupling along with sufficient hose to reach the attack pumper or siamese as well

               as any adapters needed

           b. Once the hose is secured to a fixed object, signal the apparatus driver that it is safe to move

               the engine

           c. Connect the hose to the intake on the attack engine or the siamese on the sprinkler or

               standpipe system

           d. At the water source, the engine will be set up to receive water from a hydrant or a static draft

               source

      4. Laying dual lines of 2-1/2-inch or 3-inch supply line from the scene to the water source

           a. Remove the coupling along with sufficient hose to reach the attack pumper or siamese as well

              as any adapters needed

           b. Once the hose is secured to a fixed object, signal the apparatus driver that it is safe to move

              the engine

           c. Connect the hose to the intake on the attack engine or the siamese on the sprinkler or

               standpipe system

          d. At the water source, the engine will be set up to receive water from a hydrant or a static draft

              source

      5. Hydrant connection

             NOTE: Hard sleeves can be used for hydrant operations but they are designed for drafting

             operations and may not withstand the hydrant pressure

            a. Engine can connect to the streamer connection using a soft sleeve

            b. Engine can connect to the 2-1/2-inch connections using a section of supply line (2-1/2-inch

                to 5-inch)

           c. If a hydrant valve is used, the engine can connect to the hydrant valve using a soft sleeve (a

               separate supply line will be needed to connect the engine to the hydrant valve to boost the

               pressure in the supply line)

           d. If the steamer connection is used, a hydrant gate or ball valve can be connected to one of the

               2-1/2-inch hydrant connections for later use as needed

           e. If the hydrant has plenty of water and pressure, the engine at the hydrant can connect to both

              the steamer and the 2-1/2-inch connections or two engines connect to the hydrant

           f. The hydrant should be opened and closed completely while backing off one-half turn when

              opening or closing

      6. Setting up for draft

           a. Drafting can be done from any static water source including a portable tank
