A friend has shared some info regarding a new fixed foam system for tank fire! The video is amazing to watch, especially if you have spent anytime on a hose line at a large diamater tank fire! This company is apparently very new and is focusing their efforts in Europe for now, but man is this ever needed here in the USA. I have no idea as to cost, but you can learn more about them and watch the video at http://english.foamfatale.gr/live_test.
