wot?

Problem is, that when people try to imagine what an air tank failure
would look like, their imaginations become filled with fuel/grenade/
gasoline/actionmoviebull**** type explosions.

The escape of normal (135psig?) air pressure out of a failed metal
tank will not be accompanied by a full perimeter failure releasing a
rather benign quantity of stored energy. It will release in a fart-
like measured amount.
It will be a big howling puff, but no bang, and any **** flying will
be because of the startle factor, not due to released energy.

For giggles, my mechanic and his friends hooked up a motorcycle inner
tube to a 165psig line in a garage and just let it get bigger and
bigger. So big in fact that a huge hernia appeared which became almost
see-through thin. When it failed, it made a bang, much louder than a
balloon, but not mortar launch grade. The flying remnants did knock
over a beer, much to the chagrin of one the participants. Yes alcohol
was involved. No blown-out windows. The hose-end with the metal nipple
did fly around for quite a while till the main valve was shut off.
