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. The fire fighter trainer can also have a personal tracking device for determining a fire fighter trainer'"'"'s position in the fire scenario. The tracking device can communicate with the control system to determine if the fire fighter would have been in danger due to the fire and smoke.

means for reigniting the burner assembly, said reigniting means in electrical communication with said determining means; and

a personal tracking device for determining a fire fighter trainee'"'"'s location in relation to the burner assembly.

2. A fire fighter trainer as described in claim 1 wherein the personal tracking device comprises a tracking unit to be worn by the fire fighter trainee and a receiver electrically communication with the tracking unit for maintaining a track on the fire further trainee.

3. A fire fighter trainer as described in claim 2 where the control system comprises a fireman down control for determining if a fire fighter trainee would have been in harm based on the location of the fire fighter.

4. A fire fighter trainer as described in claim 3 wherein said parameters comprise values for determining heat content of the object.

5. A fire fighter trainer as described in claim 4, wherein said control system comprising a computer having a memory, said parameters stored in the memory.

6. A fire fighter system as described in claim 5 wherein the burner assembly comprises a fuel delivery system, an ignition system and at least one burner, said ignition system in electrical communication with said control system.

7. A fire fighter system as described in claim 6 wherein the ignition system comprises a pilot assembly and an ignition transformer, said ignition transformer in electrical communication with the computer such that the computer can control the ignition transformer to cause the pilot assembly to light.

8. A fire fighter system as described in claim 7 wherein the fuel delivery system comprises a flame safety relay for shutting off gas to the burner if a sensed condition takes place.

9. A fire fighter system as described in claim 8 wherein the detecting means comprises a suppressant catchment system for measuring amount of fire suppressant and electrically communicating a corresponding signal to the control system, said suppressant catchment system in communication with said control system.

10. A fire fighter system as described in claim 9 wherein said suppressant catchment assembly comprises a first portion for measuring liquid fire suppressant and a second portion for measuring foam fire suppressant.

11. A fire fighter system as described in claim 10 wherein the first portion and second portion are in fluidic communication with a common channel, said channel having a screen for separating foam from liquid.

12. A fire fighter system as described in claim 11 including a smoke generator in electrical communication with said control system.
