U.S. Navy Divers - Recompression Chamber Setup 

That's some technical stuff good work

I assume this would be used for divers in case emergency recompression was needed...nice to know the Navy is does all it can to protect their service personnel when hazardous dives are made.........

Hahaha, the dude reading the systems checks sheet had no fucking idea what he was doing. Literally shitting himself the whole time.
