A gas dispensing system particularly adapted for use as an emergency oxygen inhalator includes a gas storage tank and gas distributing apparatus enclosed in a case having an access opening therein. The access opening is opened and closed by means of a transparent cover which shows the tank and dispensing apparatus inside the case and makes it easy for a user to quickly find and use the oxygen inhalator.
