Just to further explain the danger of compressed air:

A sufficient volume of air at single-digit IWC (Inches of Water Column) can, if released suddenly, make its presence known throughout a brand-new building (by shaking if I recall correctly) with the building's biggest door wide open to vent any sudden releases of air straight outside. I wasn't in that building at the time--but I heard about it.

1 IWC = 0.036 PSI per Google's converter (I rounded).



And the item containing said air was, in fact, rated for gases.
