This weekend I finally embarked on my rescue diver course. I may get around to writing a course report once I've done the open water section in a few weeks but for now I thought I'd jot down a couple of points here, because genuinely I did learn a couple of things from an incident we had.
To give you a build up of the picture we found ourselves in prior to the incident at the bottom of the pool.
First thing Sunday morning we did a swim test. I'm not entirely sure that it's a requisite on the course any more, but like our DM said, you're not much use as a rescuer if you can't swim very well. Fortunately I can and so the 400m swim didn't cause me an issue, and neither did the 20 minute water tread with arms out of the water for 15 seconds every minute. One of the lads though, was a slightly weaker swimmer. Still completed the task, but certainly looked to be struggling, to the extent that when after the water tread when we had a 2-lap race i opted to dawdle along with this chap at the back and keep an eye on him.
After more towing round the pool (with two open water students hanging onto the victim's feet), rescue breathing, stripping kit off unconscious divers, more towing and rescue breathing, a couple of mini scenarios etc, we finally hopped into the bottom of the pool to do unconscious diver lifts, toxing diver lifts and a basic skills assessment consisting of underwater BCD replacements, weight belt removal and replacement, mask-fallen-off-and-landed-on-the-pool-floor-in-bad-vis drills, and so on. This was where it went a bit wrong.
(Now I should point out that I've mentioned the swim test and the towing 3 people round the pool thing and everything else to make the point that by the end of the day when we got to the underwater bit, we'd been physically working quite hard all day so maybe concentration wasn't what it might have been - but maybe that's a good thing on a RD course. Dunno. Never done one before)
One of the basic drills is regulator recovery. Standard enough stuff - chuck your reg dramatically over your head, blow little bubbles, tilt right, put your right arm on your arse, make a big sweeping motion et voila, you have an LP hose by your shoulder with a source of air at the end of it. One of the chaps, who also felt uncomfortable doing a mask removal earlier, really struggled with this. Basically it looked like he didn't like the idea of not having a reg in his mouth, which 5m underwater, is quite normal, I'm sure.
On his first attempt, our local friendly DM, hovering behind, put the reg in an obvious easy to reach place when he missed it first time, and so he succeeded in recovering it. After he'd regained his composure, the instructor asked him to repeat the skill. Again he failed, but then in about half a millisecond, his mouth was wide open with no bubbles coming out of it, his eyes were like saucers and he was off the surface, with a DM hanging onto his leg, an instructor in hot pursuit and two other rescue students kneeling (sorry) on the bottom looking at each other going "what the f*ck just happened then???"
Kudos to the DM and Instr, they got him settled, brought him back down and we continued the session.
So what I learned about diving from it.
1. When it goes wrong for someone it goes wrong very very very fast, and while you're watching them and figuring out what's up, they've launched for whatever option 1 was - in this case the surface, but equally it could have been my primary reg or a mad scramble to unhook my octo in its non-standardised "somewhere in a triangle" position on my BCD.
2. I'm not as experienced as I thought I was. That's the first time I've seen anyone properly panic underwater.*
3. The lad had been diving 3 years, his last dive was 5 months ago. It was only afterwards I found out he'd only done 14 dives in total. If I'd known that, and combined it with his slightly weak swimming, maybe I'd have put two and two together and kept a closer eye on him as my co-student/buddy.
*talking through the whole episode with the instructor afterwards, I've offered to come and hang out at the back of a few OW classes where I'm told such incidents are a bit more commonplace which I think will help me identify the warning signs of a potential underwater incident.
If this has been a bit rambling or is the most obvious thing in the world to you old hat instructors then I apologise, but I figured if I learned something from it then others might too.
