Video of a C02 hit

Excellent post. I learned something about how long you could be affected.

Green for you.

Repacking used sorb is not common place in my circle of Rebreather friends.

Can Rebreather World ask HSE for permission to distribute and make this excellent video downloadable from this site? Ideally the full resolution version.
Take care

Wow.

I just got certified on my Meg last week, and our instructor specifically warned us about doing that exact thing. Im glad she did,too.

The man from the HSE, said his enquires led him to believe that the practice of tipping out the scrubber, mixing it up & putting back in was common practice. I find this quite hard to believe...

Is it commonly done?

Otherwise & interesting video....

I assume that when it said his breathing rate was 200 litres/ minute they meant 70 lpm rate at 3bars pressure. Even so, that rate wasn't dropping appreciably when he switched to OC. I had always assumed 50lpm, falling to 20 lpm after a couple of minutes. Very unnerving.

I think the blurb on the HSE website says that it's fully transferable.

Damn lucky he recognized that something was wrong and bailed.

Anyone know how long this diver was using an Rebreather? The "wrong instruction" seems to go beyond just that specific practice. Why was there not a deeper understanding of what exactly the scrubber does so that they'd have perhaps questioned the logic of reusing sorb?

Inspired Trainer · 27th November 2007, 21:23

rather than all the heart felt back slapping...wouldnt the name of the instructor be of interest to anyone? presumably this guy wasnt the first or last...

why did it take almost 3 years for this video to come to light?

these guys must have had HSE quals to do this work...were they diving within the acops while using boxes?

a cluster all round

There was no deeper understanding because it's all black magic. Some people in this forum have suggested that the used sorb accidentally lines up somewhere so there's a passage. At some point this video seems to suggest that (during the annimation). I've argued differently stating the concentrated reaction (reaction front) is more dispersed and so is the heat. A lower temp makes a less efficient scrubber. Actually the " reaction front " was mentioned at the near end of the video.

In line with my reasoning I think you'll get away with this practise in the tropics but not in cold water....

I had assumed it was subject to HSE investigation and so kept under wraps till this was concluded but this is just my guess.

On YD it was mentioned that the cameraman re took his CCR Mod1 in 2005.

The video was posted on YD and some of the reaction was typically anti CCR. But this incident had nothing to do with the units.

Safety Diver???? that has to be the loosest terminology since i took a rather dodgy training course where the bloke in the burger van was our surface cover

This group of divers quite obviously had no protocols in place to deal with any type of incident. The chap is apparently hanging on the wreck at the end breathing at 100lpm with the other two just looking on and doing not a lot.

What this demonstrates is crap training, lousy dive planning on the day and poor buddy skills.

I laughed out loud when the commentator said hes only alive today because of the teem around him. My thoughts were he survived despite the teem around him.

Sadly it also demonstrates that when your diving on a CCR there is no such thing as an easy dive. 18m is a deco stop not a dive, but it has to be taken just as seriously as a 50m dive.

I didn't see any off board bailout on the rigs? i am assuming he bailed to inboard gas. As a result his 100lpm would have lasted about 6mins tops and still at the end of the vid I could see no sense of urgency in preparing for ascent. Perhaps the "team" lept into action off camera.

At first glance it would appear to be a poorly conceived and badly exicuted dive for what are obviously professional divers. If i am wrong then the video needs a re edit because thats how it looks now.
