Gbro good point. While working at a defense contractor we were having problems with the local fire marshal. Like so many individuals who are not involved with the Explosives industry he had a "Hollywood" perception of explosives.
We took him to our test range and demonstrated a series of explosive fires. None of them detonated.
We then initiated a BLEVE (boiling liquid vapor explosion) using two standard 20 lb propane tanks. The explosion was excellent. He did not change his mind on explosives but tried to ban propane tanks in his city. Shortly thereafter he was quietly retired.
