Supply Line Operations

Firefighter Review Session Reference: 1 Topic: Supply Line Operations Time Required: Three Hours Materials:    • Two Fully Equipped Pumpers    • Static And Pressurized Water Sources References...


      b. Second pumper connects to steamer connection of first pumper and takes excess water from

          hydrant

  2. Dual pumping involves two pumpers directly attached to same hydrant taking pressure and flow

      from separate lines

      a. First pumper connects to steamer connection and takes water

      b. Second pumper connects to the 2-1/2-inch connections and takes water

 

III. Supplying Water From Various Sources (1-3)

A. The student will perform the following evolutions:

  1. Using the split lay, set up water supply from a pressurized source using a single line to supply a

      second engine at the scene.

  2. Using the split lay, set up water supply from a pressurized source using dual lines to supply a

      second engine at the scene.

  3. Using the reverse lay, set up water supply from a static source using LDH, to supply a second

      engine at the scene.

  4. Set up water supply from a hydrant using multiple engines. The evolution should include the use of a

      hydrant valve.

  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 from a hydrant

      or tanker.

  6. Using a straight lay, set up water supply from a pressurized source using LDH while initiating

      supply from a booster tank.

  7. Using a reverse lay, set up water supply from a static source to a master stream device using a

      single supply line while initiating supply from a booster tank.

B. The evolutions will first be reviewed by the instructor before being run with moving apparatus.

C. All water will be discharged into a master stream device which is already set up or connected directly to the pump.

D. These evolutions are designed to expose the student to various methods of supplying water at the fire scene. The student should already be familiar with the techniques involved in each evolution. What is being emphasized here is teamwork and operating efficiency.

 

IV. Various Supply Lines And Appliances (1-4)

A. During the above evolutions, the students will utilize as many of the following devices which are available as possible.

  1. Water source devices

       a. Hydrant devices

           1) Humat valve

           2) Hydrant gate

           3) Ball valve

           4) Butterfly valve

      b. Static source devices

           1) Siamese (clappered)

           2) Gated siamese

  2. Water supply devices

       a. Gates wye

       b. Gated manifold

       c. Water thief

       d. Master stream devices (deluge or deck gun)

B. The appliances will first be reviewed by the instructor before being used as part of the evolutions with moving apparatus.

C. The student should already be familiar with the appliances required.
