Is the surface the most dangerous part of the dive?

[Nemrod]

Yeah, the fins on the arms thing and tag lines in general. I try to avoid all of that. I usually either plan to hit the ladder first (and then help if needed) or last after the mayhem has subsided. I then swim to the ladder and if it is a closed lader I hit it with one finned foot, stand up, remove the dangling fin and hand it up and then place that foot on the next rung and then remove the other fin and hand it up. If it is an open fin ladder then I come up the ladder with fins on.

Obesity with divers is a burgeoning (pun) problem to say the least. I am not talking about delightfully plump or handsomely dad bodded, or even quite rotund. But when a diver cannot get into and out of the water without assistance of four people trying to hoist them into the Zodiac, it becomes not just a danger to them but to the other divers, the crew and all involved. When you get older, well, obesity it is a problem.

I've looked at the BSAC incident report for 2022. The highest number of incidents started at the surface, see graph.

Do they list by incident type anywhere? I wonder if there isn't a certain type of entry such as shore entry in a heavy surf causing divers to fall over and hit themselves/each other?

Are all DCI incidents not recorded as surface incidents. If so then the greatest number of incidents which are DCI will naturally be recorded as surface incidents, the surface is not the reason for DCI.
Edit; are fast assents also recorded as surface incidents,

Interesting. But did the graph include incidents that began at depth and were concluded on the surface including DCI? Supposedly one must go under to a depth and time in excess of prudence to get bent, that the result manifests itself at the surface is not really a surface issue? Another, over exertion at depth precipitating a cardiac event, then a panicked or unresponsive diver and then the result being dealt with eventually on the surface, it began at depth. But, still, the graph is very telling! Thanks.

Yeah, you can read different things into it. I would think all DCI incidents should be listed as "depth"-- or there is no DCI/DCS.

BSAC reports make good reading but the entire report needs to be read to get a handle on whats going on, reports from the coast guard and the RNLI are included, and are surface incidents of mechanical failures, missing divers or any request for assistance. Where depth is concerned, the depth is unknown in a lot of incidents. A breakdown of all the reports can be read.

Thanks. great work done on these reports.

Yeah, but it is like saying most of deaths happen in the hospitals so you should watch out for them...
and when you are sick, where would you rather be?
