There are reciprocating air saws and cut off tools that need 90 PSI and consume between 10 and 20 CFM. The intermediate pressure (low pressure ports) on a scuba rig is somewhat higher (125 -145 PSI) but I would venture a guess that these tools will take it. As far as water immersion is concerned they are cheap enough to be thrown away after emergency use.
