Scuba tank safety
When you own your own tanks: bring them to a professional for filling and regular inspection.
Scuba Cylinders need to be visually inspected once a year which is a legal requirement. The scuba tank inspection involves removing the valve and looking inside for signs of corrosion or damage. If the tank is deemed safe, an Evidence of Inspection (EOI) sticker is applied to the tank showing the date of inspection.
A hydrostatic test is required every 5 years, this very high pressure test determines the tank's ability to contain pressurized gas. Survial Sports is a certified hydro test facility and we will stamp the shoulder of the tank below the valve with the date of pass.
If you rent equipment, this inspection makes it easy for you to know if your rented tank has been properly maintained and inspected. If the hydrostatic test stamp is more than 5 years old or the EOI sticker is more than a year old, don't accept the tank.
Corrosion is the major cause of tank degradation. Scuba tanks are filled with very dry air which prevents moisture to build up in the interior of the tank. Certified divers learn never to leave a tank empty. Always leave at least 50 barsi of pressure in the tank at the end of your dive, so no moisture can get in when valves are opened.
Handle all scuba tanks with extreme caution! Never let them fall down.
Please watch the below video produced by the Swiss firebrigade that shows what happens when a tank valve breaks!
The tests were made by the Swiss Firefighters Federation after several incidents have occurred during operation or training, with steel or composite tanks. The last one shows a tank with a flow limitation valve. These valves are now mandatory for use in Switzerland.
