    Study Notes

    Firefighter Ceiling Collapse Hazards

    • A firefighter becomes trapped under a collapsed ceiling during a fire rescue operation
    • Ceilings are often underestimated as a structural hazard during firefighting
    • The exact cause of death for firefighters in ceiling collapses is often misattributed to burns or smoke inhalation
    • Ceilings are categorized as directly affixed or suspended, with different collapse characteristics
    • Directly affixed ceilings, found in older buildings, collapse in small pieces and usually cause minimal injury
    • Water absorption into plaster from hose streams can cause sudden collapses in directly affixed ceilings
    • Older structures with thick, heavy plaster ceilings pose a risk of serious head or neck injury to firefighters
    • Suspended ceilings, commonly found in stores, top floors of multiple dwellings, and renovated buildings, present the most dangerous collapse hazard
    • Suspended ceilings are designed to cover old ceilings, insulate top floors, and conserve energy in renovated buildings
    • When the vertical supports of a suspended ceiling are destroyed by flames, the entire grid framework collapses, posing a serious hazard
    • The type of ceiling and its collapse characteristics should be considered in firefighting operations to mitigate risks
    • Understanding the potential hazards of different ceiling types can help improve firefighter safety during rescue operations

    Fire Safety Precautions for Suspended Ceilings

    • When a suspended ceiling collapses during a fire, a rush of fresh air mixes with superheated gases, potentially causing an explosive fire increase.
    • A collapsed ceiling with a wood framework can fuel the fire, giving firefighters trapped below very little time to be rescued before the fire and smoke reach them.
    • Sweeping the collapse area with a hoseline to knock down flames is the crucial first step to rescue trapped firefighters in a store fire.
    • A ladder should be ready at every fire to rescue trapped victims or firefighters suddenly trapped by ceiling collapse and fire.
    • If rescue attempts are made without extinguishing the fire, trapped firefighters may succumb to the products of combustion before being reached.
    • Firefighters should be trained to recognize occupancies with dangerous suspended ceilings, such as stores, top floors of multiple dwellings, and renovated buildings.
    • Proper examination and communication of the type of ceiling in a structure is essential before committing firefighters to a serious fire in a large-area occupancy.
    • Hose streams directed into a concealed space to extinguish a spreading fire can contribute to a collapse if the suspended ceiling's vertical hanger strips have been weakened by flames.
    • Proper methods of opening a ceiling with a pike pole are crucial to prevent a fire-weakened suspended ceiling from collapsing.
    • Firefighters operating at a serious building fire with the possibility of a suspended ceiling collapse should attempt to stay near large pieces of furniture or stock that can serve as shelters or voids.
    • Shoring techniques should be practiced to temporarily shore up weakened ceilings, especially during overhauling.
    • Tunneling beneath collapsed ceilings with portable ladders can help firefighters examine areas below quickly and protect against fire increase.
