I agree. And I know Ragasco tests what happens to a composite tank in
a fire. It will not explode. Here is a video:http://www.ragasco.com/files/documen...pg_complet.wmv

But it will burn like a torch until the gas is all gone and it will
probably fall over since the supports will all melt... All I know
about it is what I read on the executive summary he

http://www.cabinetheatersafety.com/i...fm?pageid=3282.

There is a link to the video and a full report on the site also. It
was worth reading the whole summary report. It seems that the plastic
tanks all fail at the joint between the tank and valve and then vent
until empty. Steel tanks vent when the internal pressure gets very
high and then close again when the pressure drops. They didn't test
AL tanks. If they burn that would be the worst case, but I don't
think they would at those temps. Seems to me that steel would be the
least horrible in a fire all else being equal.
