  1. Auto Extrication WELLINGTON COUNTY

  2. Overview • Apparatus Response to MVCs - Know Your Role • Vehicle Stabilization • Extrication Techniques • Pneumatic Lifting Bags • Hybrids and Electric Vehicles • Holmatro Book

  3. Crew Organization • A systematic approach to vehicle extrication is the best way to ensure that tasks are performed as quickly yet as effectively as possible. • The only way to effectively perform a systematic rescue is through team work. • In order for a team to work in perfect unison they have to know exactly what is expected of them and have confidence in their abilities and skills to perform their specific tasks. • The ideal number of rescuers for a simple single occupant entrapment is approximately 5-6

  4. Actions of First Arriving Rescue to Simple Single Occupant Entrapment Officer of Rescue: • Arrival report • Take command • Assign one crew member as “medic” • Assign crew (except medic) to outer and inner circle checks • Assign one crew member “in charge” of cribbing • 360° Size up (if possible) • Think of a Plan A and B

  5. Actions of First Arriving Rescue to Simple Single Occupant Entrapment Crew of Rescue: • Outer and inner circle checks – update Captain of all hazards and remove/isolate/protect • “Medic” make verbal patient contact • Crib the vehicle as per firefighter in charge of cribbing • Listen for Plan A and B from Captain • Disconnect Battery (Both terminals – Negative first) • Glass management • Make access for “Medic” or EMS • Proceed with Plan A

  6. Actions of First Arriving Rescue to Simple Single Occupant Entrapment Driver of Rescue: • Use truck as initial blocker to protect crew and scene • Chock wheels • Set up tool staging area close to vehicle with ALL extrication tools set up and ready to go • Set up lighting as required • Keep tool staging area as well as extrication work circle tidy and organized • If a firefighter has to go to your truck to get a piece of equipment, you’re not doing your job! • Watch for trip hazards • STAY OUT OF THE EXTRICATION

  7. Actions of First Arriving Rescue to Simple Single Occupant Entrapment

  8. Second Pump/Aerial Arrives On Scene Officer of Rescue: • Pass command to Officer of second in pump/aerial and assume Rescue Sector Officer of Pump/Aerial: • Assume Command Crew of Second Pump/Aerial: • Charged 38mm (1½”) hand line minimum • Stay out of the extrication unless requested by Rescue Sector Officer Driver of Second Pump/Aerial: • Stage truck as scene blocker (protect rescue) • Chock wheels • Pylons out • Charge the hose • Lighting as required

  9. Second Pump/Aerial Arrives On Scene

  10. Roadways with speeds of 90 km/h or less: • When an incident is of a nature that firefighters will be laying hose or otherwise working on the roadway, apparatus should be positioned to provide a safe work zone for the firefighters, until police assume traffic control.

  11. Roadways with speeds of 90 km/h or less: • Where apparatus will be parked without protection of a “Blocker”, vehicle traffic cones should be used by apparatus operators to control traffic flow around the parked vehicle, giving enough room for a walkable safety zone around the vehicle.

  12. Vehicle Stabilization

  13. Vehicle Stabilization • Primary goal of stabilization is to maximize the area of contact between the vehicle and the ground to prevent any sudden or unexpected movement of the vehicle. • NEVER test the stability of the vehicle as it is found. Three typical resting positions of a vehicle after collision: • Upright • On its side • Upside down • Other (i.e. piggyback vehicles)

  14. Vehicle on its Wheels • Chock Wheels • Minimum 4 point crib • Placed behind front wheel well and in front of rear wheel well on both sides (ideal) • 6 point crib – vehicle in danger of collapsing • Installed under the middle of both sides of the vehicle (below B-posts)

  15. Vehicle on its Wheels

  16. Vehicle on its Side • To ensure that the vehicle does not fall over, place wedges under A and C pillars as well as the under side. • Be aware of “fall zone” • Shore the under side with Res-Q-Jacks • Depending on the situation it may be necessary to use the Jacks to stabilize the roof side of the vehicle.

  22. Vehicle on its Roof • Crib the roof rails between the back of the vehicle and the ground • Add additional cribbing to the space between the engine compartment and the windshield for additional stability • Wedges under the front of the vehicle to prevent forward movement • Necessary to use Res-Q-Jacks if roof supports will be compromised during extrication (i.e. inverted roof flop)

  25. Piggyback Vehicles • Goal is to make both vehicles “one” • Stabilize lower vehicle first then stabilize upper vehicle • If patient is trapped in lower vehicle, ratcheting upper vehicle to lower is sufficient • If patient is trapped in upper vehicle, ratchet vehicles together but use Res-Q-Jacks for added support on the upper vehicle

  27. Extrication Techniques

  28. Extrication Techniques • Firefighter and patient safety should be foremost in the Officers’ mind when selecting a Plan A and B • Choose the easiest route available • Try before you pry • Firefighters and Officers need to know the common names of the various extrication techniques and how to perform them to prevent delay during an extrication

  29. Common Extrication Techniques • Door pop • Full side • Third door conversion • C-post lift • Roof flap • Inverted roof flap • Horseshoe/Trench cut • Tunnel • Dash lift/roll (ram & spreaders)

  30. Common Extrication Techniques Door Pop: • Removal of a single door • Used when patient is critical

  31. Common Extrication Techniques Full Side: • Removal of both front and back doors including B-post • Full C-spine for front seat passengers

  32. Common Extrication Techniques Third Door Conversion: • Creating a wider opening on two-door vehicles • Allows access to rear seat passengers • Full C-spine for front seat passengers

  33. Common Extrication Techniques

  34. Common Extrication Techniques C-Post Lift: • Used when side access of vehicle is limited or blocked • Full C-spine for front seat passengers • Very quick

  41. Common Extrication Techniques • Horseshoe / Trench cut:

  42. Common Extrication Techniques Tunnel: • Access is made through the rear of the vehicle • Great for vans, SUVs and hatchbacks • Full C-spine for all patients

  43. Common Extrication Techniques

  44. Common Extrication Techniques Dash Roll: • Helps free leg entrapments

  45. Common Extrication Techniques Dash Lift: • Helps free leg entrapments

  46. Pneumatic Lifting Bags

  47. Pneumatic Lifting Bags Various shapes and sizes High, medium and low pressure

  48. Pneumatic Lifting Bags RULES: Plan operation before starting the work Be familiar with equipment Have an adequate air supply and sufficient cribbing on hand before beginning operations Position bags on or against a solid surface Never inflate bags against sharp objects – use protective mats Never inflate bags fully unless they are under load (4 bar max when not under load) Inflate bags slowly and monitor them continuously for any shifting

  49. Pneumatic Lifting Bags Never work under a load supported only by lifting bags Do not stand in front of pressurized bags Shore up the load with enough cribbing to support the load in case of bag failure Interrupt the process frequently to increase cribbing – lift an inch, crib an inch Ensure that the top tier is solid when using box cribbing Avoid exposing bags to materials hotter than 220°F (104°C). Never stack more than two bags; centre the bags with smaller bag on top and inflate the bottom bag first (½ full), then inflate the top bag fully.
