A scuba tank, or cylinder, is a major investment for a scuba diver, ranging in price from $100 to more than $500. If the scuba tank isn't stored properly, moisture can enter the tank and cause corrosion, or the tank valve could rupture, both of which can be very dangerous. Luckily, the process of storing a scuba cylinder is quick and simple, requiring just a cool, dark environment and a little bit of air in your tank.
Things You'll Need
- Cool, dark room
- Scuba tank with some air left in it
Find a cool, dry location to store your tank. Hot temperatures can cause the valve discs on your tank to burst. There are no specific rules as to what temperature is best for storage, but a cool room that doesn't vary much in temperature is recommended.
Check the tank's gauges. Ensure that the "bar" reading is between 10 and 20 and the "psi" reading is between 100 and 300. Storing your tank when it is full can increase the likelihood of corrosion due to moisture in the air, and it can be a fire hazard. Storing the tank with just a little bit of air in it actually helps to keep moisture out of the tank.
Position the tank upright. Divers are often told to transport a cylinder on its side, but when storing a dive cylinder long term, positioning it upright helps to let any moisture in the tank settle at the bottom of the cylinder where an inspector can spot it.
Tips & Warnings
- If you do store your tank with air for more than six months, make sure that you get it refilled prior to use, as it can go stale.
- Make sure that your tank isn't likely to get knocked over, which can damage the tank and any other items the tank might land on.
