This is a one-hour lesson in which the dispatcher will listen to two 9-1-1 calls, the first involves receiving a 9-1-1 call reporting that several people are stranded and injured after a flash flood suddenly came over a waterfall into a popular state park wading area. The second 9-1-1 call involves a resident waking up to a strange car in his driveway. Once he goes outside he notices that his car is gone, and the strange car has an infant inside it.  Both 9-1-1 calls present a challenging scene that the dispatcher must work through.  Dispatchers will use a computer to read through the lesson and learn best practice in interrogating callers reporting such incidents. The lesson addresses the need to determine the exact location of the victim; transferring the caller to a secondary PSAP for Fire/EMS if within agency guidelines; caller, responder, and scene safety; ascertaining if weapons were present; the need to obtain suspect description information and routes of travel; and controlling the interview.
