[VAC] Re: Refrigerator question

If any of you have had the opportunity to view a fire service training film
entitled "BLEVE" (acronym for Boiling Liquid, Expanding Vapour Explosion) I
am sure you would opt to have your propane tanks closed while on the road.
One cut shows a hundred foot or more furrow plowed up in a farmer's field by
a railroad car tank that landed over a half mile from the scene of the
fire/explosion.  If you ever sit at a rail crossing watching the cars go by,
look for the "LT WT" rating on the tank cars.  That is the "light" or empty
weight of the car (in pounds), and is typically a very large number.  Even
if the tank itself was only half the weight of the empty car, the "steam"
explosion violent enough to send it over 2000 feet would be an impressive
experience at best.  Not that the five or ten gallons of propane would be
anywhere near as potent, but if kept in the tank, it could never catch fire
as easily as if the valve was open.

As Dr J has said, the fridge keeps everything quite cold while closed,
especially if you carry your drinking water frozen in jugs, within.
