When cabin decompression occurs at 35,000 feet, chemical oxygen generators located above passenger seats produce breathable oxygen via a chemical reaction (sodium chlorate and iron powder) for only 12 to 15 minutes. This provides more than enough time for flight crews to execute an emergency descent down to 10,000 feet where the ambient atmosphere is breathable.
