Abstract: The present invention is a fire fighter trainer. The fire fighter trainer is used to train fire fighters to extinguish a simulated fire scenario. The fire fighter trainer includes a burner assembly for providing fire and a mechanism for detecting application of fire suppressant, suppressing agent or surrogate suppressing agent. The detecting mechanism is disposed adjacent to the burner assembly, such as below it. The fire fighter trainer also includes a control system for controlling the burner depending on a signal from the detecting mechanism. The control system also comprises a mechanism for determining if a burning object simulated by the burner assembly would reignite based on application of fire suppressing agent and parameters defining a simulated burning object. The control system is in communication with the detecting mechanism and the burner assembly. Preferably, there is a mechanism for reigniting the burner assembly based on an output of the determining mechanism.
