Diver turns tank valve off instead of on
Turning the tank valve back half-a-turn often confuses divers and can inadvertently make breathing difficult at depth. This diver kept a cool head and ascended on her buddy’s alternate air source.
“While diving with my dive buddy in Florida, I noticed that upon each inhalation the needle of my submersible pressure gauge (SPG) fluctuated. The needle dipped down with each breath before returning to the correct psi reading for my tank. I continued diving while keeping a close eye on the gauge and, upon reaching a depth of approximately 55 feet, (16 meters) it suddenly became very difficult for me to breathe. I looked at my SPG mid-breath and saw the needle drop down to zero psi, and it did not readily move back up. I felt like there was no more air available to me even though I knew there was at least 1200 psi (80 bar) in my tank. I signaled “out of air” to my buddy, and used her alternate regulator. We made a controlled ascent to the surface, and I was not injured. Upon inspecting my gear, I realized that instead of turning my tank all the way on and half a turn back, I had turned it all the way off and half a turn on. Upon reaching a depth below 33 feet (10 meters), I had experienced inadequate air pressure delivery from my tank to my regulator because the tank was barely on and could not continue to deliver the same volume of air at the increased pressure.”
The diver most likely did not sufficiently open the tank valve before their descent. The valve was open enough to provide some air at the surface and in shallow water. As the diver descended, however, they did not get enough air. They tried to open the tank, but in the attempt they turned the valve in the wrong direction, shutting it off completely. The root cause of this incident may have been the oft-suggested practice of opening a valve all the way and then turning it back a half turn.
In the early days of scuba, valves were made of brass. If you didn’t turn the knob back a half turn then the valve would shrink during the dive due to cooling, and you wouldn’t be able to turn it off afterward. This is not a problem today, but old habits die hard, and many divers still turn the valve back half a turn
So always open your tank valve all the way. Open it up, and breathe easy. Ensure you do a pre-dive check and a buddy check to pick up any errors. Look at the submersible pressure gauge (SPG), take a couple of breaths, and if you can breathe and the needle does not move, you are good to go.
