Because the tank split straight at the seam, it does look more like an
overpressure failure than anything else.
No, I don't believe that. The compressor only jumped up a couple feet, and
didn't knock the guy down. And, apparently, he survived. If the tank had
let go at 120++ PSI, likely both of them would have been killed, one by
being squashed against a wall or ceiling, and the other by flying debris.

Even small receiver failures are notoriously fatal, and the damage to the
shop testify to the HUGE forces involved. These things do almost as much
damage as an artillery shell. From the video, it seems that this one let go
at well below 100 PSI. It was enough to flatten the tank, though, so more
than, oh, maybe 25 PSI or so (And I'm no expert on the dynamics of rupturing
tanks.)
