In a gaseous oxygen system, what are vented to blow out plugs in the fuselage skin?

Oxygen filters
Pressure relief valves
Oxygen supply lines
Pressure regulators

The correct answer is: Pressure relief valves

Pressure relief valves are used in a gaseous oxygen system to safely release excess pressure. Oxygen filters, supply lines, and pressure regulators may be connected to the system, but they are not vented to blow out plugs in the fuselage skin. Therefore, they are not the correct answer. The pressure relief valve is the only option that accurately describes what is vented in this situation.
