Most people know what a scuba diving tank looks like, but only a few people actually know what it exactly is or how to use it. If you are interested about scuba diving, but don’t really know much about this highly essential piece of equipment, you might want to read on.
Most people think that the scuba diving tank contains pure oxygen, but actually it doesn’t. A scuba diving tank actually has around 21% oxygen and 79% nitrogen, which is rather similar to the air we breathe. In reality, if scuba diving tanks were filled with pure oxygen, they would be toxic when brought to shallow depths. And thus for recreational driving, compressed air is needed.
The typical recreational scuba diving tank is usually made of aluminum, holding about 80 cubic ft of compressed air. A scuba diving tank usually is two feet high, with a diameter of ½ foot. Normally, scuba diving tanks are filled with at least 2000 psi and at the most 3000 psi of gas pressure. To maintain quality standards, scuba diving tanks are monitored by the US Department of Transportation.
Using a scuba diving tank isn’t that difficult, here are some reminders:
1. Have the scuba diving tank filled by a reputable diving shop.
2. Check if the intake pipe of the shop’s compressor is in an area with clear and fresh air. Chose another shop if it is placed somewhere there are fumes which could get inside the pump.
3. Don’t ever leave the scuba diving tank inside a parked car because heat could cause it to expand and explode.
4. When traveling, store the tank in the car trunk, with the valve facing the passengers. In case the valve gets damage, the tank will be propelled away from the passengers.
5. Before using the tank, remove its rubber valve protector and check its O-ring. If it is damaged or missing, replace it.
6. Attach a buoyancy compensator on the tank’s body.
7. Attach the first stage of your regulator on the scuba diving tank’s valve.
8. Turn the valve’s knob counterclockwise to open it and then turn it back for a half turn.
9. Take note of the tank’s pressure by checking the gauges.
10. As you scuba dive, always check on the tank’s remaining air pressure.
11. Stop scuba diving way beyond the tank’s minimum pressure point.
12. After you dive, remove all the attachments from the tank and store them in a cool area.
Managing a scuba diving tank is easy if you know what you have to do. Enjoy scuba diving!
