1. An oxygen pressure relief and ventilation system, comprising:
a flow fuse fluidly coupled downstream of a pressure regulator, wherein the pressure regulator is operatively coupled to an oxygen tank, and the oxygen tank is located in an unpressurized compartment of an aircraft;
a pressure relief valve fluidly coupled downstream of the flow fuse; and
a ventilation pathway fluidly coupling the unpressurized compartment with a pressurized compartment,
wherein the flow fuse and the pressure relief valve are configured to cooperatively mitigate downstream flow of pressurized oxygen if the pressure regulator fails, and
wherein the ventilation pathway is configured to allow air from the pressurized compartment to pass through to the unpressurized compartment for diluting a concentrated oxygen in the unpressurized compartment.
