What information is usually marked on scuba tanks?

Scuba tanks are equipped with important safety information to ensure their proper use and maintenance. The date of hydrostatic testing is crucial because it indicates when the tank was last tested for structural integrity under pressure, ensuring that it remains safe for diving. This testing is required at regular intervals to verify that the tank can withstand the pressures it will encounter underwater.

Additionally, the serial number is used for identification and tracking purposes. It allows manufacturers and dive shops to manage their inventory effectively, keep records of inspections, and address any potential issues or recalls associated with specific tanks.

While manufacturer details, type of gas, and maintenance history may be important in other contexts, they do not encompass the essential safety information marked on the tank itself. The hydrostatic test date and serial number specifically highlight the tank’s condition and traceability, which are vital for divers to ensure their equipment is safe before use.
