    Study Notes

    Collapse Rescue Operations Overview

    • Greatest danger during collapse rescue: secondary collapse.
    • First step in collapse rescue plan: secure the area to ensure safety.

    Utilities and Hazards

    • Utilities must be shut off to prevent electrocution and gas explosions.
    • Approximately 75% of collapse victims are rescued during initial five steps of the plan.
    • Heavy fire presence from flammable materials increases site danger.

    Search and Rescue Techniques

    • "Time-out" should occur post-initial surface and void searches for assessment.
    • Limited oxygen or gas accumulation is the major hazard in void spaces.

    Types of Collapse

    • Lean-to collapses happen due to load-bearing wall failure, creating angled debris formations.
    • Primary danger in below-grade rescues involves gas accumulation and electrocution risks.

    Equipment and Safety Measures

    • Water-soaked debris is particularly dangerous when in contact with live electrical wires.
    • Heavy construction equipment is deployed only after rescuing all surface and void victims to minimize risks.

    Firefighter Safety Protocols

    • Full protective clothing is required during early stages to ensure safety.
    • Avoid mechanical equipment near hand digging areas to prevent further collapse risks.

    Utility Management

    • Utility shutoff must commence immediately due to potential delays from utility companies.

    Methods of Searching and Rescuer Safety

    • Void search specifically targets victims trapped in crevices within the debris.
    • After critical life-saving operations, a risk-benefit analysis is recommended.

    Lighting and Evacuation

    • Position lighting above the collapse pile during nighttime operations for optimal visibility.
    • Falls and tripping on debris are common injury causes during emergency evacuations.

    Structural Concerns and Worker Safety

    • Shut off electric supply before entering below-grade areas to prevent electrocution risks.
    • Contact with water-soaked debris and live wires is the main electrocution hazard.

    Heavy Equipment Protocol

    • Firefighters should stop digging if heavy equipment is being used nearby for safety.
    • A wall shifting by ¼ inch is a critical threshold for evacuating rescue workers.

    Management of Machinery Use

    • Heavy machinery operations require an assigned officer to oversee safety protocols.

    Fire Spread Risks

    • Large air spaces and exposed wood at collapse sites can accelerate fire spread.

    Post-Rescue Actions

    • After rescuing surface and void victims, withdrawing and reassessing site safety is vital.

    Role of Search Dogs

    • Search dogs assist in locating the positions of buried victims to enhance rescue efforts.
