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.
