We have already beaten this horse to death about 18 mo. to 2 yrs ago. Look in the archives. We have used out of the box regulators with 100% O2 on scuba tanks at 2250 psi for years without a problem. U.S. Divers, Sherwood and Poseidon. I know firsthand of only one instance where a fellow used a ten year old regulator that had been overhauled one year before but never used- he used it on a scuba bottle full of 100% O2 at 1500 psi and jammed the valve open. The regulator flamed for an instant producing lots of smoke then dumped O2 until it emptied the tank. When the smoke cleared and the guy dug himself out of the pile of shit he excreted, it was determined that a first stage Oring that had been slathered with grease by the dive store technician on the theory that if a little was good then a lot was better had caught fire. The high pressure hose for pressure gauge ruptured at the regulator and that was where the O2 escaped from. Nothing else caught fire except the greased O-ring. The guy should have mentioned to the dive store tech that he was going to use it on high pressure O2. I won't bother to tell you where this event took place because it would only make you never attach your O2 reg. with 100% O2 in the head of your 35 foot cabin cruiser. On the other hand it is handy if you have the shit scared out of you. The only case of O2 fire during diving was reported on techdiver when we were first beating this horse to death. The diver had previously finished eating a well-known national brand of fried chicken before the deco on 100% O2 and had not taken the precaution of O2 cleaning his mouth. It caught on fire during the 20 foot stop. When he was interviewed after the dive, all he said was, "mmmpppfffoooccckkkker".
