- 1. Auto Extrication Safety for the Rescuer Abbotsford Fire Rescue Training
- 2. Introduction • Awareness class about Auto Extrication Safety • Targeted at AFRS personnel that may be required to perform auto extrications
- 3. •Learning Objectives • Students will realize that undeployed or “Loaded” airbags are dangerous to rescuers • Precautions need to be taken to be taken to prevent injuries during an auto extrication • More education is needed in this matter
- 4. Topics of Discussion • Vehicle Construction • Safety Restraint Systems • Airbag Requirements • The Old Way • Deployment Hazards • Extrication Safety
- 5. Basic Vehicle Construction • A, B, C, Posts
- 6. Safety Restraint Systems (SRS) • Airbags – How do they work? • Collisions – Sensors • Locations • Auto fires – System failure – Where are they?
- 7. Airbags
- 8. Airbags
- 9. Safety Restraint Systems (SRS) cont’d • Rollover Protection Systems – What are they? – Where are they? – How do they work?
- 10. Rollover Protection Systems (ROPS)
- 11. Rollover Protection Systems (ROPS)
- 12. Rollover Protection Systems (ROPS)
- 13. •Safety Restraint Systems (SRS) cont’d • Seatbelt Pretensioners – What are they? – Where are they? – How do they work?
- 15. Which vehicles are equipped with SRS • 1974 GM introduced airbags in Oldsmobiles and Cadillacs • Since 1987, over 60 million vehicles have been equipped with airbags • 1997 Side impact airbags introduced
- 16. Which vehicles are equipped with SRS • 1998 - 2 airbags required in all vehicles • 2002 - 4 airbags will be required in all vehicles
- 17. The Old Way • Chop and Bend • Roof • Steering Column • Getting in the car
- 18. Deployment Hazards • Why are we worried? – SRS don’t deploy in 30% of crashes – They may “go off” at any time after the crash • from a few seconds to a couple of days later
- 19. Deployment Hazards • Airbag deployment – Speed • 200 mph • SMART system varies speed • Dummy Tests
- 20. Deployment Hazards • Compressed Gas Cylinders • Pyrotechnic Devices – Inflation Devices – Seatbelt Pretensioners
- 22. Deployment Hazards • Deployment Zones – 15 inches for driver side – 20 inches for passenger side – 5 inches for side airbags
- 23. Extrication Safety • Scene Assessment – Assure general scene safety • Traffic • Chemicals & Fire • Vehicle stabilization & Environmental hazards – Determine if vehicle is equipped with SRS – If unable to verify, assume it is!
- 24. Extrication Safety • Even if there is little to no damage to the vehicle, evacuate occupants if airbags are present. • Use extreme caution when retrieving items from the vehicle. • Use your left hand to release the hood.
- 25. Extrication Techniques • Cut the Seatbelt as close to the pretensioner as possible – Avoids whipping – Avoids further injury to patient • If vehicle is equipped with power seats and windows, push them back and lower them
- 26. Extrication Techniques • Disconnect Battery – Negative first – Be sure cables will not spring back to terminals – Check for metal intrusions to battery casing – Disconnect auxiliary electrical devices such as cell phones
- 27. Extrication Techniques • STAY CLEAR of Deployment Zones!!!! – 15 inches for driver side – 20 inches for passenger side – 5 inches for side airbags – ROPS
- 28. Extrication Techniques • Do not cut or bend B and C posts or steering column • Treat every undeployed “Loaded” airbag as if it is live
- 29. What This Means • We are facing extreme danger at almost every incident involving a vehicle • Stay clear of Deployment Zones • Don’t just cut and bend • THINK - Use common sense
- 30. What are we doing about all this? • Getting the word out • Researching the subject • Developing a training program
- 31. What can you do about this? • Pass this information along to your men • Look for more information • www.extrication.com
