The danger of an oxygen rich atmosphere is that any combustion reaction is intensified! I believe that Gus Grissom and several other astronauts died as a result of an electrical fault (short circuit) in a confined space that was oxygen-rich and that everything that was combustible (wire insulation, seat covers and foam padding, paper and clipboards, etcetera) burned with incredible rapidity and intensity! Check with AGA or one of your local welding suppliers to see if they are offering any educational demos on the dangers of combustible gases and oxidisers (oxygen). Well worth the time!
