In DVD 1, Vehicle Extrication: Vehicle Technology/Alternative Fuel and Safety Systems, Dalrymple addresses the challenges and concerns in performing extrication on traditional and alternative fuel vehicles. Manufacturers have introduced numerous structural and safety systems to make vehicles lighter, stronger, and safer than the vehicles of just a few years ago. Responders need to stay current with trends in automobile technologies such as airbags, rollover protection structures (ROPS), motive power, and construction considerations in order to maintain a safe extrication environment and increase the responders' chances of a swift, safe, and successful extrication.
