Talking security in his workshop!

Interesting. I'm accustomed to periodic hydrostatic testing with scuba tanks and, I assume, with welding gas tanks, though it never occurred to me to test air compressor tanks.

Scuba tank pressures can be upwards of 3000 PSI, while air compressor tanks generally operate under 200 PSI. Still, integrity testing does make sense. Even a low-pressure tank could spoil one's day if it lets go catastrophically.
