How Long Does Air In Scuba Tank Last?
by Robert Bauer

I bought a new scuba tank 12 years ago and never used it. The tank is now 12 years old. Is the air still safe to use?
Thanks for getting in touch. Whether the air in your tank is good or not is actually now a secondary question. The tank in question is long past due for inspections.
All tanks, whether steel or aluminum, have to pass a hydrostatic test every 5 years and a visual inspection every year. Obviously this has not been done.
Since the tank has not been inspected in so long, I would definitely get it tested before using it. Corrosion could have started inside the tank which could affect the oxygen levels.
While there may be nothing wrong with it, I think it is better to be safe than sorry.
Let us know how it goes.
