For those interested in this product-please contact Firefox Industries (www.firefoxind.com). They have it and can supply you with the info you are looking for as to its efrfectiveness versus AFFF. They are one of the firms that has both materials available. It is important to understand that FE36 is a replacement material and is better suited to very specific use. I have asked them to work with me on my install of AFFF and how the GCR reads with positive results IMO. I will agree that there are a number of things the CRB should examine as to fire safety systems and their application to all classes. I still carry a 2.5 Purple K bottle simply because I want to. The Firefox AFFF system will disrupt most any fire that we might encounter. The gas version has similar charactewristics.
Need further contact help drop me an e-mail. My shop is very near theirs <G>.
