Are oxygen cylinders subject to periodic hydrostatic testing?

Oxygen cylinders are indeed subject to periodic hydrostatic testing to ensure their safety and integrity. This testing process involves filling the cylinder with water and pressurizing it to check for any leaks, structural weaknesses, or material fatigue. The aim of this procedure is to prevent accidents that could occur if a cylinder were to fail during use, especially since they contain gases at high pressure.

Hydrostatic testing is mandated by regulations for compressed gas cylinders and typically occurs every 3 to 5 years, depending on the specific type of cylinder and local regulations. This requirement is crucial in maintaining the safety standards associated with the storage and transportation of gases used in various applications, including diving. Understanding the importance of routine testing helps ensure that divers are using equipment that adheres to safety protocols, safeguarding both their lives and those around them.
