    Study Notes

    Dangers of Slate and Tile Shingle Roofs for Firefighters

    • Slate or tile shingles can be 2 inches thick and weigh up to 10 pounds, posing a significant danger when falling from a height.
    • A fire in a four-story brownstone mansion in Manhattan resulted in severe injuries to FDNY Lieutenant Robert O'Connell due to collapsing slate shingles.
    • Slate and tile shingle collapse can be caused by destruction of the wooden roof deck by fire, sudden temperature changes, and powerful hose streams.
    • Firefighters have been killed or injured by falling objects such as slate shingles, tools, and even people jumping from windows near fire buildings.
    • Slate and tile roofs can conceal a fire-weakened roof structure, leading to unexpected collapses without warning signs.
    • The chances of a firefighter losing balance and falling off a sloping rooftop are greater than those of being injured in a roof collapse.
    • Ice, snow, rain, and humidity can make slate and tile roofs extremely slippery, posing a hazard for firefighters working on them.
    • The pitch of a roof is a crucial factor in determining its safety for firefighters to walk and operate on.
    • Firefighters can protect themselves on peaked roofs using roof ladders hooked onto the ridge rafter or by operating from an aerial or tower ladder.
    • Only standing and operating from an aerial ladder or platform can protect a firefighter from a rafter collapse on a peaked roof.
    • Fire departments must have standard operating procedures and necessary equipment, like aerial ladders, to safely operate and vent peaked roofs.
    • When preparing a pre-fire plan for a hazardous building, firefighters should identify the type of roof construction and include it in the plan.
