as far as static electricity starting a fire, anyone looked at their gas bar-b-que or natural gas stove lately? it uses a quartz crystal to provide a tiny spark in the gas stream and will most certainly get a fire going. there are numerous cases of cigarettes starting fires in COPD patients clothing due to oxygen saturation of the clothing, I think the largest risk of using O2 in your drysuit would be after you took the shell off and were walking around in your woolies. the danger while diving would be minimized from lack of heat or ignition source. I never hear static crackling when I take my suit on and off. I dont think I would risk it unless it was an emergency and I had no other gas to use. My .02
