ABSTRACT:
The invention is a mask that can be used as an aircraft passenger oxygen mask, survival and escape mask. The mask includes a connector ring for connecting an oxygen supply. The oxygen connector is held connected to the mask by a pin, but can be removed with the pin in place by utilizing a break-away ring mounted in and held in place in the mask by an O-ring. Valves in the mask and connector allow a person to breath in oxygen and exhale while the oxygen supply is connected, and to continue to breath in through a filter and exhale through a valve after the oxygen supply has been removed.
