Allen,
Yes I did. They use these in race cars, airplanes, RV?s, workshops, etc. Any place where there is heat or a fire source or potential for fire. It is used in high heat close quarters areas. If memory is correct I want to say 350 degrees is where it sets off but I may be incorrect with this. There are videos giving examples of a fire near then it setting off automatically, which very efficiently and completely put out the fire.
Contact Nichole Wheeler at Proteng and she will kindly address all your concerns.
They gave a very good presentation at our last EAA meeting and we were all impressed. It?s a great safety device with many applications. Not to stir any negative comments, but my opinion is that most small fire extinguishers are just a false sense of security. Sure, better than nothing but not equal to or certainly not better than this.
I had a friend crash in an experimental years ago. He survived the impact only to be trapped inside. The roofers several houses away witnessed the crash and could hear him screaming for several minutes as he burned to death. No one was able to get to him fast enough. Horrible death I want no part of. Safety is an attitude as we are all taught.
