How often must medical gas cylinders be hydrostatically retested?

Medical gas cylinders must undergo hydrostatic retesting every five years to ensure their safety and integrity. This testing process is crucial because it checks the cylinders for any signs of weakness or failure that could lead to dangerous leaks or explosions when under pressure. By requiring retesting at this five-year interval, regulatory agencies help guarantee that these cylinders can safely contain gases for medical use, protecting both patients and healthcare workers. Regularly scheduled retesting is a standard practice in safety protocols for high-pressure gas cylinders across various industries, including healthcare.
