What method is used to assess the serviceability of an oxygen cylinder?

The method used to assess the serviceability of an oxygen cylinder focuses primarily on its structural integrity and ability to safely contain gas under pressure. A pressure test with water is a common and effective technique for this purpose.

Conducting a pressure test involves immersing the cylinder in water and then pressurizing it. This allows for the detection of any leaks or weaknesses in the cylinder walls that might not be visible through external inspection. If the cylinder is compromised, it will show signs of bubbling or water escaping, indicating that the cylinder cannot safely hold oxygen at the required pressure.

This method is considered safe and reliable, as it visually demonstrates the cylinder's functionality and integrity under conditions that simulate operational pressures. Other methods, while valuable in some contexts, do not directly confirm the cylinder's capability to withstand its intended operating pressure in an effective manner.
