    Study Notes

    Definition and Characteristics of Commercial Buildings

    • Commercial buildings include structures used for business, manufacturing, and storage, primarily non-residential.
    • These buildings vary in size and complexity, being able to stand alone or be part of other occupancies, often multi-story and below grade.
    • They typically contain large volumes of contents, including hazardous materials, and have less compartmentalization than residential buildings.

    Firefighting Strategy Differences

    • Residential fire tactics are not effective for commercial fires; minimum flow rates should follow NFPA 1710 standards.
    • Large open spaces in commercial buildings complicate search operations due to fire and smoke conditions; residential areas allow for more effective searches.
    • Quick fire extinguishment is vital to ensure victim safety, especially in known rescue scenarios.

    Fire Behavior and Conditions

    • Commercial fires are more complex due to large areas and heavy content loads, producing severe fire conditions.
    • Early fire attack when the fire is at its smallest state is critical for success.
    • Supporting existing building fire suppression systems enhances control of fire situations.

    Water Volume and Application

    • Large volume handlines (minimum 250 GPM) are necessary for effective fire attack.
    • NFPA 1710 mandates at least three handlines with a collective flow of 500 GPM or more.
    • Application can be executed from either interior or exterior positions depending on fire conditions.

    Tactical Considerations

    • In offensive strategies, Company Officers should use adequate water flow to combat the fire.
    • If conditions are unsafe for interior suppression, switch to a defensive strategy, utilizing exterior water application when necessary.
    • The strategy employed must be responsive to changing conditions, emphasizing water volume to overcome fire intensity.

    Ventilation Challenges and Techniques

    • Effective ventilation in commercial buildings requires careful planning, taking into account building size and natural openings.
    • Horizontal or vertical ventilation strategies should be coordinated with fire attacks for better effectiveness.
    • Vertical ventilation can be challenging; adequate exhaust openings may be difficult to achieve due to building volume.

    Coordination and Communication

    • Incident Commanders (IC) must work with Sector Officers for effective ventilation and fire control.
    • Preventing rapid fire growth is crucial while fire companies operate inside the building, necessitating constant communication and reassessment of conditions.
