From TColJeep: In a case of regulator failure, out of air situation or switching over to a Deco gas you will need to remove the face mask, switch over to your octopus and don a spare mask. You definitely want to practice this in a pool as it may save your life.

This is a must, I worked as a rescue diver for human powered submarine races, many of the two man crews wore full face mask so they could talk but didn’t carry spares and had never practiced switching :(
