    4. Pipe should be equipped with several diameters of solid stream nozzles and at least one large-caliber fog nozzle

  B. Setting Up Aerial Pipe

    1. Spotting turntable

      a. Aerial pipe may have to be operated with truck in unfavorable position - spotted for rescue or venting

      b. Aerial pipe operations may begin upon arrival

      c. Buildings

        (1) Where wind not a factor, turntable should be spotted for maximum coverage of fire area - usually center of building

        (2) If building is fairly wide, unit should be spotted in middle of involved area

        (3) When wind blowing across face of building so that nearby structures exposed, turntable should be spotted between fire and exposures

      d. Open storage areas

        (1) When wind not a factor, turntable should be spotted for maximum coverage of fire area

        (2) When wind a factor, turntable should be spotted at flanks of fire between main body and exposures

        (3) Unit should not be positioned directly in path of fire

        (4) Also used to protect fire fighters advancing handlines toward fire - turntable should be spotted either behind or at flanks of advancing fire fighters and streams directed just ahead of fire fighters

      e. Flammable liquid handling facilities

        (1) Turntable should not be spotted in line with either end of horizontal tanks

        (2) Unit should be positioned at side and stream used to cool tank as well as attack main body of fire

    2. Developing water supply

      a. Pipe water supply most often developed in cooperation with engine companies

      b. Pumper should be positioned close to truck due to high friction loss and flow requirements

      c. Joint operations should be practiced

    3. Rigging aerial pipe

      a. Platform pipes

        (1) Permanently mounted to aerial platform

        (2) Water supply connected to intake siamese

        (3) Platform raised, and pipe released, aimed, and charged

        (4) Pipe should be charged before basket moved toward fire

        (5) Platform pipe stream and spray system under basket available to protect fire fighters in basket

        (6) Fire fighters in basket should wear life belt connected to side rail

      b. Bed-mounted ladder pipes

        (1) Pipe permanently mounted to bed section of ladder

        (2) Water supply connected to intake siamese

        (3) Halyard attached to pipe for vertical control from turntable - turntable rotated for lateral movement

        (4) Nozzle released from holder, ladder raised to position, and pipe charged

      c. Ladder-tip pipes

        (1) Place pipe on ladder with proper nozzle for fire and wind conditions - must be positioned dead center and locked down securely

        (2) For additional safety, pipe can be tied to ladder rungs

        (3) Ladder pipe hose connected to pipe

        (4) Attach handle and halyard for vertical control (NOTE: pipe should not be operated from tip of ladder) - rotate ladder to move nozzle laterally

        (5) Siamese connected to ladder pipe hose and supply lines connected to siamese - should be shut-off valve between ladder pipe hose and siamese if siamese not gated

        (6) Ladder raised, and pipe aimed and charged - pipe should be charged before moved toward fire

        (7) Fire fighter operating halyards should be positioned on turntable

  C. Aerial Streams for Fire Attack

    1. Nozzles

      a. Fog streams more effective if can reach seat of fire

      b. Solid streams have longer reach and can penetrate further

      c. Both fog and solid nozzles rated according to water flow in gallons per minute - either type will lose effectiveness if not supplied with at least rated flow

      d. Pipe should be fitted with proper size as well as proper type of nozzle

    2. Stream placement

      a. To direct fog stream through window, place nozzle at approximate center of opening and set at 30-degree angle
