    Study Notes

    Flat-Roof Operations

    • Position apparatus at building corners to maximize scrub areas and reduce hazards from fire venting out windows.
    • Use ladders at corners to access the strongest parts of the roof with fewer window risks.
    • Check the distance from the top of the coping wall to the roof to gauge ladder placement safely.
    • Estimate coping height by measuring from scuppers to the wall top or from vents to the top of the wall.
    • Identify gas piping and machinery on the roof to assist with ventilation planning.
    • Avoid placing ladders on coping due to potential instability and risk to firefighters; ensure ladders extend at least 6 inches above coping.

    Gas Line Installation Hazards

    • Gas lines run through wall spaces and trusses, vulnerable to damage during renovations or firefighting operations.
    • Be cautious when accessing appliances, as flexible gas lines can be easily compromised by tools like axes and pike poles.
    • Lines may exit through elbow fittings that can stress connections in confined spaces, leading to potential leaks.
    • PVC pipes may encase gas lines but provide no real protection; lines remain unguarded in truss spaces.

    Firefighting Strategy

    • During fires, secondary hose lines may be deployed to protect exposures and control fire spread.
    • The first engine may opt for rear or side access to basement fires, avoiding staircase "chimneys."
    • If the initial line is in the basement, a second line should be positioned at the top of the basement stairs for safety.
    • Communication with officers about actions taken is critical, especially concerning gas appliances.

    Fire Fatalities Analysis

    • When recovering fire victims, note their position, clothing adequacy for the weather, and any inconsistent injuries.
    • Victims often found face down suggest attempts to escape; face-up positions may indicate collapse.
    • Bright red blood pools under victims could indicate injuries prior to death, necessitating further investigation by the Fire Marshal.
    • Documentation of the victim's condition and location is vital for fire investigation records.
