I stopped reading after page 3...
Here are the four things I tell my students about MOF:
1. With quarry conditions calmer than most swimming pools, I have seen people lose their masks after they placed it on their forehead. Just compound this with rougher condition. Depending on how far up (and back) you push it, the tension in the mask strap can help it the rest of the way off. Why risk the $50+ on something as simple as as not putting it on your forehead.
2. I try to break them of the habit of immediately removing thier mask upon surfacing. I want to impress upon them to keep the mask on and regulator in just in case something goes wrong on the surface. This something can be as simple as someone dropping something (and you can watch it drop and go get it) to helping someone in distress.
3. If you are exiting in deep water, exit with the regulator in and mask on just in case you fall back in or need to help someone else with their exit.
4. It will prevent the MOF-fanatics from giving you a hard time.
A distressed diver strives to get to a comfortable condition. For non-veteran divers, the conformtable condition means nothing on their face and regulator out of their mouth. So in their efforts they make the natural moment of pushing the mask away from the eyes and nose. Pulling it down is not natural since they want it away from them. So once you push it away it will end up on your forehead or in the water behind you.
Yes, MOF is a *potential* sign of distress. The distressed divers that I have seen never had their mask squarely on their forehead head, it was always skewed or still covering like one eye. It obviously was pushed out of the way with haste. Otherwise, the distressed diver didn't have a mask on since they got rid of it already. Good thiing I didn't rely soley on the MOF = panic.
