Ron Gordon – SETT training – Using a wine bag and let it pop

What was introduced, was one of the best ways I’ve ever seen it to be explained.

‘Cos the worry is people not blowing out enough, when their lungs go, and what they used to do was to get … you know the old wine boxes? When you take out the inside, the bit of silver with it, you know.

So, you take one of them down to the … empty of wine by the way, down to the bottom of the Tank in the bell, and then you just put some little bit of air into it and then you’ve got the camera on that, and you just release it and the buoyancy starts to take it up, and you’re doing you’re instructions, then this is you coming up though the water.

If you don’t blow out, this is what’s going to happen to your lungs, and they can see it on the camera going up and up and about 30 feet from the surface when the effect of the atmospheric pressure takes more effect as you get closer to the surface, you suddenly see it go up and  ‘phhzt’, bang!

They think shit, that’s what can happen to your lungs.
