As folks that know me, I’m always screaming GPM GPM GPM, because if you want a fire to go OUT, you MUST COOL it below the IGNITION Temperature. The only way to do THAT is by matching the GPM to the generated BTU! Before anyone says these types of fires cant be put out, id challenge them to critically RE-THINK their understanding of BTU/lb and thermal capacity of water!
Ask yourself this question, how much heat can 1 pound of water absorb at 4,000 ft altitude at a temp of 45 degrees F. ? then ask yourself how much heat 1 pound of LC95a absorbs at the same altitude and temp? The answer might shock you.
