well, i think an option "Yes" is missing. i can reach but it's not very important for me. i answered the first option but it does not truly reflect.

I have been certified for 33 years and dive often. A lot of agencies teach the 1/4 deal . originally started to save pressure on the o-ring in the valve.
If it is off you will know it no air when you test the second stage.
Agencies such an IDEA don't teach the 1/4 deal.
By the way I have dozens of instructor certs from many agencies

Only a moron needs a 1/4 turn test to know a valve is on.
All the valves you have used your whole life, on your tolilet, sink tank ccw on cw off!

That is not true. There are some things that use left handed threads.

Yes there are,....but you would be talking about table saws and items with motor type moving parts.
If you are old enough to remember the turn table, (record player), radios in cars with knobs or other electronic items that used knobs. The fact is that the standard is ccw to turn on and cw to turn off.
the best way to take care of a problem is to eliminate it. The valve is either on or off. YOu would find out when you pressed your second stage and octo to test and power inflater, If you bypassed this,.. If it is off and the hose is full of air, you won't get two - three breaths before it's dry. Not finding out 20' down.
I know there are people that cannot remember which way is on and off. I have seen them on the dive sites trying to figure it out. I know there are people that have to think, HARD,.. about ccw and cw. I have never heard anyone simply tell students ccw on,..cw off.
With that being said,...if you cannot figure out how to turn on your air,.. or ccw from cw. I have serious doubts about you scuba diving. I would not want that person as my buddy!!!!!!!!!!
Your shower/bath valves open ccw close cw
keys open ccw
Door knobs that open only in one direction open ccw
Your first stage yoke knob opens ccw,.. closes cw
The back plate of your dive watch to replace the battery opens ccw and closes cw.
Why do people have a problem with this??? Your doing it automatic without thinking hundreds of times a day.
Question,.. let's see if you were taught this. What do you do with a runaway power inflator??
