7 Phases of Rescue Operation
- 1. Scene Size-Up
- 2. Hazard Control
- 3. Patient Access
- 4. Medical Treatment
- 5. Disentanglement
- 6. Patient Packaging
- 7. Transport
- Establish Command
- # of Patients
- Search, Rescue or Body Recovery?
- Risks vs. Benefits
- Request Additional Resources, if needed.
- Wear Proper PPE
- Traffic Control
- Biological Agents
- Confined Spaces
- Envrionmental Hazards (Lightning, Avalanche...)
- Psychos/Violoent People on Scene
- Stabilize Location
- Simple Measures Before Complex
- Noise Level Minimum
- Proper PPE
Medical Treatment (Load 'n Go Situations)
- Vehicle Fire
- Unstable/Volatile/Hazardous Materials
- Rising Water
- Trench Cave-In
- O2 and IV Lines Secured
- Immobilization to Long Board
- Splint Fractures/Dress Wounds (if time allows)
Confined Space Hazards
- O2 Deficient Environments can be Fatal
- <19.5% O2 is Hazardous
- >22% creates Rapidly Combustible
- (Tanks, Storage Bins, Manholes, Wells, Mines, Silos, Underground Vaults)
Permit-Required Confined Space
Spaces with physical or atmospheric hazards that cannot be controlled by continuous forced air ventilation alone.
Non-Permit Required Confined Space
No physical or atmospheric hazards.
Rescue Requirements for Entry
- Atmospheric Monitoring
- Lock Out/Tag Out of Electrical Utilities
- Dispersion of Stored Energy
- Disconnect All Pipes That May Flow into Space
- Don Appropriate PPE
Trenches and Caves
- 1 cubic foot of dirt weighs 100 lbs.
- 2 feet of soil on a person's back can weigh 700-1000 lbs.
- Shoring required if over 5' deep.
Reasons for Trench Collapse
- One or both lips of trench cave in
- Wall of trench caves in
- Removed dirt falls back in (spoil pile too close)
- Intersecting trenches
- Ground vibrations
- Previously disturbed soil
- Water seepage
