I store my bottles horizontally when on the truck. Our procedure, when going to use it, is let the bottle stand upright for at least 5-10minutes. This lets the acetone and acetylene settle properly. Had a plumber friend have one of his guy's not do this and the regulator blew. One B-tank size bottle burned down a 3-story apartment building and part of the building next door. Even with 3-fire extinguishers, they still couldn't put it out. Have to have a lot of respect for this gas.
For use in welding and cutting, the working pressures must be controlled by a regulator, or the gas will spontaneously combust.
Got the pic off EHOWA. Didn't say it anyone was injured or not..... Appearantly the bottle was leaking in the back of the van and its suspected that the remote door locks, when cycled, triggered the explosion. Sure hope no one was close to it. Don't see any body bags around, that could be a good thing.
that's why you don't transport stuff like that (including propane tanks) in ENCLOSED vechiels such as vans, trucks with camper shells, trunks...........
because you never know.
a lot of people do not know this at least in California its a 25,000.00 fine (per cylinder) for transporting uncaped or with a regulator attached even with being properly secured
tanks with built in valve protection ( similar to BBQ tanks) are excluded from being caped
