    Study Notes

    Water Supply for Firefighting

    • First due engine companies must secure a water supply when they approach a scene with signs of a working fire.
    • Exceptions to securing a water supply include potential rescues needing full crew response, uncertainty of fire location in complex buildings, and fires in high-rise structures.

    Special Considerations

    • Unique environments such as hillside homes, junkyards, recycling facilities, and high fire-load areas necessitate pre-planning for hose-lays and water sourcing.
    • In remote areas with limited hydrants, options include drafting from canals or using extended supply lines.

    Tactical Water Supply Management

    • Adequate supply lines must reach all tactical positions utilized by fire companies for both interior and exterior attacks.
    • The number and configuration of supply lines depend on water supply requirements outlined in the incident action plan.
    • Techniques such as "big water" evolutions, tandem pumping, and relay pumping may be employed based on the fire's water supply needs.

    Considerations for Laying Supply Lines

    • Supply line placement should minimize access issues; ideally, hoses should be laid along the hydrant-side of the road and crossed at the fire scene if needed.
    • Slower speeds during hose-laying reduce the risk of accidents involving civilians, vehicles, or firefighters.
    • Taking time during hose-laying allows the Company Officer to assess critical factors at the fire scene and lets the Engineer position the apparatus effectively.
