LP gas school was one of the most fun classes I ever took, along with the ARFF training. The hissing of the gas releasing is a sound you'll never forget.Some pics from my fire academy. Last night we did dumpster, car and propane tank fire simulations.
We burned an abandoned house a few weeks back, and someone had thrown a few camping propane cylinders in the root cellar unbeknownst to us. They hissed then let off a massive bleve. Second time I've been near a bleve, the other was a structure fire that lit off a 20lb propane tank. We had calls about that from 5 miles away.
Have you done Haz-Mat yet? Usually that is saved for last, but terrifying fun.
