    OBJECTIVES


    Fire stream selection

    • Need sufficient amount of water to cool the fuels that are burning.

      • Fire load and materials involved

      • Volume of water needed for extinguishment

      • Reach needed

      • Number of persons available to handle hoseline

      • Tactical requirements

      • Speed of deployment

      • Potential fire spread

    FIRE STREAM SELECTION


    Direct attack

    Most efficient use is at base of fire with solid or straight stream.

    Water applied in short bursts until fire “darkens down”

    Water not applied too long to prevent upsetting of thermal layering.

    DIRECT ATTACK


    Fvcc fire rescue

    • Water applied in short bursts until fire “darkens down”.

    • Using a straight stream to attack the seat of the fire reduces the chance of upsetting the thermal

    • layering in the room.

    ?

    Adequate ventilation must be provided ahead of fog streams that are used for interior attacks


    Indirect attack

    • Considerations when not to use

      • Victims

      • Where spread of fire cannot be contained to uninvolved areas.

    INDIRECT ATTACK


    Indirect attack1

    • Fire stream

      • From outside window or door

      • Could be solid, straight or narrow fog pattern

      • Should be aimed at an upward angle to deflect off the ceiling or other overhead object

      • Placement should provide maximum coverage on the face of the building, taking into account if more than one is in use

    INDIRECT ATTACK


    Combination attack

    • Utilizes a stream generating technique of ceiling level attack with a direct attack on burning materials near floor level.

    • Nozzle may be moved in a “T”, “Z” or “O” pattern.

      • Using a solid, straight or fog stream

      • Rotating with the stream reaching ceiling, wall, floor and wall

    COMBINATION ATTACK


    Master stream

    • Master streams are deployed:

      • When fire is beyond control of handlines

      • Need for fire streams in location where firefighters are no longer safe

    MASTER STREAM


    Master stream1

    • Positioned to provide an effective stream

      • Has to be shut down to move

      • Should be directed at the base of the fire

      • Angle should be aimed at an upward angel to deflect off the ceiling or other overhead objects.

      • Should be placed to provide maximum coverage on the face of the building taking in account if more than one is in use.
