"As small aircraft and helicopters have become more complex, technology has provided systems that have enhanced operational safety. In the event of an accident, many of these systems have presented additional hazards to first responders or any potential rescuer at an aircraft accident scene. The FAA [Federal Aviation Administration], in cooperation with General Aviation Manufacturers Association (GAMA), various manufacturers and first responder professional organizations, has developed training for safety at an aircraft accident scene. While the material was initially developed for firefighters, Emergency Medical Services (EMS) and police, it provides useful information for any persons that may come across an aircraft accident. Flash Player is required to view each module."
