I've heard of only one incident using rich nitrox in a DS. The Darwin Candidate decided that a burning charcoal handwarmer was appropriate in a high O2 environment inside his suit...

Perhaps best not to use O2 with an electric suit warmer
Seriously though I only need to find one reference to an O2 fire (not via burning charcoal heater

) and the ideas a no go...anyone?
