A
  1. Upon dispatch of a working fire in a structure in a non-hydrant area, a Tanker Task force should be added at the discretion of the initial engine company or the battalion chief.
  2. Lay out supply line from the driveway to the incident. This should be done from where the supply pumper and dump tanks are to be located (the dump site). This may require a split lay.
  3. Assign fifth engine to fill site operation duties and designate fill site location.
  4. The lay out from the first engine should include a Siamese on the supply line whenever possible.
  5. Advise incoming units of the mode of attack and supply line position according to the preplan

  2. Drop dump tanks, hard sleeves, low level strainer, and other ancillary devices for dump site operations. Drop an additional Siamese and hose for the dump site engine.
  3. Once a draft is established from the dump tank by the dump site engine (normally the second engine), the tanker dumps its remaining water into dump tanks.
  4. Once the tanker is empty, this unit becomes part of the shuttle operation and proceeds to the fill site.

25
Q

What are the responsibilities of the 2nd due engine in a shuttle operation?

A
  1. Engine driver sets up to supply water to the first engine from the dump site by hooking a line to the Siamese attached to the first engine’s supply line.
