VIDEO: In some of the most serious crashes, victims are trapped inside vehicles, and it's up to first responders to get them out safely; however, a lot more than expertise goes into tackling these tough situations. On Sunday, May 6, various scenarios were simulated as part of 5 Alarm Fire and Safety Equipment's annual "Jaws of Life" training school. "You got to control your emotions and your adrenaline. They have a plan for how to execute it, and in the real world, obviously, lives hang in the balance," said Peter Walker, Hartland Fire Department captain and 5 Alarm instructor.
