First, if the diver did screw up the reg switch and go to long hose from
the back gas instead of his stage or deco tank, it would not be an
immediately fatal error since the back tanks alway hold the deepest mix you
will breathe.  So, no tox.

Second, the procedure I learned, when using mulitple tanks and mixes, the
valve on all stage and deco tanks is turned off until you use them.  When
switching to a stage or deco tank the diver first checks to make sure they
turned on the valve for the proper tank and then the diver's partner checks
and verifies the reg/hose/tank/label before the diver breathes the reg.

Third, I don't put bolt clips on stage or deco regs to park them.  The reg
always goes back to the tank when not in use.
