Erm... The volume in the suit is going to be very small. And O2 isn't flammable! So, in the cigarette example even if you opened the suit and waved the cigarette around, all that will happen is that the cigarette will burn faster. We're not talking about filling the DS with Camping Gaz...

I suspect that the average undersuit would burn beautifuly in 100% O2, see iain-hsm post 20 above or remember what happened to the Apollo 1 crew? NASA Apollo Mission Apollo-1-- Table of Contents Apollo 204 Review

Certainly climbing out of an drysuit the O2 is going to dissapate rapidly but there will be plenty trapped within the undersuit for a while.

The chances of a fire in suit underwater are probably negligable but I doubt it would be survivable at 30m in open water never mind 100m in a cave and thats before we get to Neils calculation on the long term prospects for a burns victim.
