Shaft Trimix Weekend

[Ian T]

So it seems.....
I really wonder about our access requirements sometimes. We have adopted an Australian standard, have added our own policies, and yet this still seems to have to be increased at a particular site. Surely the fact we are following the standard, have increased our safety regarding OH environments is enough.
Regarding that, I am unsure if I qualify for the 10 dives myself. I do with CCR, but OC trimix dives I dont think I have 10 dives up.

JD,

The 2 within past 12 months establishes a requirement for a diver to be current for diving Trimix. We have to demonstrate currency for Tank, this is no different.

Performing post course dives, with no instructor there to hold your hand, in REAL dive sites, not just the tropics off Indo, and in a drysuit, is a big change from some peoples courses. Having that 'real world' trimix diving experience should give the landowner confidence that people diving trimix there are safe to do so.

I think the problem is that there arent many other 'trimix' friendly sites in the mount 45m+, apart from Kilsbys, 1080 and Blacks. (Damn, we need to get Grant to open Barnoolut again ! ) Now if we could get Pics to 60m that would be great, though opens up a whole other can of worms. At least Trimix in the Shaft can be tightly controlled.

Rather than seeing this as an impedient, set it as a goal to achieve the pre-reqs and lets get some diving in the shaft. You'd easily get the 10 OC trimix dives on a few day trip to Melbourne.

I'd say it is landowner driven (or ST or CB), funny how you can kill yourself in kilsby's post course diving just not in the shaft...hmmm???

it's not the first time we have seen a certification not good enough to do the diving you have been certified for..go figure

trimix in the shaft is like a training dive anyway, you are being watched and no doubt criticed, just no drills.....

by the way if we can't by Tank, then the only two holes woth buying are the shaft or kilsby's...any views

PH

ps amusing to see It shoot down JD with facts...is that a first

[Ian T]

PH,

I think the bigger concern here is people being bent. There have been a few bends this year, seen a couple on the boat here in Melb (subclinical). Most definitely can get bent in Kilsby's.

Trimix in the shaft needs to be monitored. I hardly think a 65m dive is a training dive. If people are getting bent, running out of gas, not planning their dives sufficiently for a 65m dive, then how is it able to get opened up to 80m then ? Why would the CDAA take that risk ?

Purchasing the Shaft is rather useless as you would need to purchase the access road to get to the hole. No point owning the hole if the owner of the paddock and gate only lets you on once a month !

[JD]

Ian, why would I want to do OC trimix dives just to get numbers up? I am 100m certified on OC and CCR, and I can tell you I will not be doing trimix dives on OC just to satisfy some stupid pre requisite set by someone too full of their own importance!

Why not just allow CCR? Why exclude a safer way of diving?

Ian, are you suggesting I am incapable of diving the Shaft, due to my lack of OC trimix experience? Surely 120m on CCR is more difficult than 10 dives on OC to 55? BTW, 120m is fucking deep, regardless of where it is, and requires the same planning and attention if it is in the tropics or off the coast of Melbourne. If you would like to try it out, that can be arranged!

Regardless of what the requirement is, it is just a breathing gas. Breathe in, breathe out. A 65m dive is just a 65m dive, the planning is what matters.

Relax man. Did I mention anything to do with the use / non-use of RBs in the shaft ?

Hmmm, safer way of diving ? This is a whole other argument. Assuming your aware of the fatality in Eagle's Nest this week ?

Again, Relax man. I didnt make any judgements on your diving abilities in anything written above. All I was asking was if people have met the pre-requisites to dive the Shaft. The validity of the current pre-requisites I am sure could be debated and reach no conclusion.

[JD]

Yep, the two untrained cave divers who were diving 18/30 to 100m? Clearly caused by the Inspiration that one! Unfortunately, owning a rebreather does not automatically make you smart! These guys were allegedly 'Breathing down the O2 in the loop' to get it to a safe level for 100m. Who ever told them a PPo2 of 1.98 on the dil was OK should be tracked down and handed a medal for still being alive. This is of course forgetting the PPn2 implications!

Ian the last guy I heard of getting bably bent because he ran out of gas was GUE Tech 1 trained.....

that would be part of the sale or 99 yr lease agreement

ok great 10 post course dives and you don'y get bent??

Wow PH. Simply cause YOU haven't heard about other things happening, must mean they have never happened ! I forgot to check with the font of all knowledge first, from those thousands of sources that tell you whats going on, while you sit back at your computer doing SFA. Since you know so much about everything thats happening, maybe you can tell me if I should buy a lotto ticket this week ?

There have been three bends that I know of in Mt Gambier this year. One of whom is still on crutches.

Here's an idea PH. How about getting out there and doing it, and if you're not going to, then just shut up.

 god this is fun....Ian, if you have ever taken the time to chat to Paul Axton since he become a chamber operator, which I have, I have been aware that there are a number of bends that come from the Mt and plenty that have dubias dive profiles too apparently. which is why he did not run for SD because he would have  a conflict of interest between patient privacy and his roles as SD. so yes I ahve known for a while that bends come out of the mt, actually I know you got bent there Francis Haden got bent there, shit more GUE boys getting bent....this ratio deco must be great. I personally have never been bent in Aust.

the point is this 10 post course trimix dives for a 65m dive in the shaft is not going to mean that I and Brian Cornell went for a 60m dive in the shaft that I will get bent before me....so your point is bullshit and narrow minded.

its a bit like getting your licence but you can't drive interstate until you have clocked up 10000km - over regulated crap!!!

JD and RB did you have to go and do some post course dives before Sl was happy for you to go to 120m.....same as on our trimix course

so you want me to shut up because you don't like my opinion.....well than in that case I guess I should then I suppose

[Ian T]

I personally have never been bent in Aust.

I think this is because DCI requires the an absorption of an inert gas, by diving. Bit hard to be bent when your not diving. Oh please regale us all with stories of your amazing diving history PH. Ever seen the ballroom in Tank ?

haha, ya loser.
