Why are pressure relief valves important in medical gas systems?

Pressure relief valves are essential components in medical gas systems primarily because they serve to prevent over-pressurization, which can pose significant safety hazards. In a system where gases are stored under high pressure, any failure or malfunction can lead to an increase in pressure beyond safe levels. If this occurs, the pressure relief valve functions as a protective mechanism—it opens to release excess pressure and maintains the system within safe operational limits.

This is crucial in medical settings where gases such as oxygen and nitrous oxide are used. Over-pressurization can damage equipment, lead to gas leaks, and create dangerous situations for both patients and healthcare providers. Therefore, the presence of pressure relief valves is a fundamental safety measure that helps mitigate risks, ensuring the continued safe operation of medical gas systems.
