Agree. The fact is propane is no safer but industries continued to use for decades. 1974 a hell of rail tank car propane explosion in a railyard that killed several injured hundred plus. No one quit using propane. No concern using but maybe more safty checks . I worked at a auto parts casting foundry, drove a forklift with bull ladle to a hugh hot iron furnace that poured hot iron into the ladle from above. A filled ladle is transported by forklift from furnace to line where cast mold is filled and formed by air cooling. So concerns are over exaggerated. The world world continues to turn.
