Fact is, that above about 35,000, regardless of the type of mask you wear, you're playing russian roulette. Given considerations towards time of useful consciousness, any high altitude flying (regardless of type mask) is potentially dangerous. They key thing to point out is risk management. Fortunately, the odds of having a decompression are low, in fact, the most likely reason for pressurization problems any more (modern equipment) are pilot error as opposed to mechanical failure. Based on the odds, we accept that risk. Second, the altitude rating for masks is for continuous use.
I don't know about you, but if I have a decompression at FL450, I'm not going to stay there and suck O2. I'm coming down, and in a hurry. I believe the reason is based on the FAA regulation that specifies above FL410 one pilot must be wearing a mask. See (C2),(1), (a) below.
Written by lawyers so you may need to re-read it a few times. 121.333 — Supplemental oxygen for emergency descent and for first aid; turbine engine powered airplanes with pressurized cabins.
When operating a turbine engine powered airplane with a pressurized cabin, the certificate holder shall furnish oxygen and dispensing equipment to comply with paragraphs (b) through (e) of this section in the event of cabin pressurization failure. (b) Crewmembers. When operating at flight altitudes above 10,000 feet, the certificate holder shall supply enough oxygen to comply with §121.329, but not less than a two-hour supply for each flight crewmember on flight deck duty. The required two hours supply is that quantity of oxygen necessary for a constant rate of descent from the airplane's maximum certificated operating altitude to 10,000 feet in ten minutes and followed by 110 minutes at 10,000 feet. The oxygen required in the event of cabin pressurization failure by §121.337 may be included in determining the supply required for flight crewmembers on flight deck duty. (c) Use of oxygen masks by flight crewmembers.
Quick Donning Oxygen Mask
(1) When operating at flight altitudes above flight level 250, each flight crewmember on flight deck duty must be provided with an oxygen mask so designed that it can be rapidly placed on his face from its ready position, properly secured, sealed, and supplying oxygen upon demand; and so designed that after being placed on the face it does not prevent immediate communication between the flight crewmember and other crewmembers over the airplane intercommunication system. Swabhiman serial online. When it is not being used at flight altitudes above flight level 250, the oxygen mask must be kept in condition for ready use and located so as to be[/COLOR] within the immediate reach of the flight crewmember while at his duty station. The regulation for oxygen use and TSO for the mask are two completely different things. The mask is certified for use up to FL410 cabin pressure altitude, not aircraft altitude. Unless of course one experiences explosive decompression and “stays” cruising at FL410 (nobody would), there should be no mask functionality issues and the mask should continue to operate as it is designed. When everything is working fine and you are crusing at FL450 and one crewmember is wearing/using the mask per the regulation, the mask is being used at a cabin altitude of around 8000’ at max “delta P”.
