BSAC Pre Dive Briefing with OC Divers

[PW1664]

Anyone aware of any pre-dive briefing requirements SPECIFIC to BSAC in branch dives with OC Divers?

My apologies I didnt notice which heading this post was placed.

There's this bit:

How does the buddy check differ?

Review/modify the buddy check procedure to accommodate the rebreather layout especially the shutdown operation of the mouthpiece.

The buddy check should ensure the buddy is aware of the risks and knows the appropriate emergency procedures. For example; the rebreather user should state the possible additional problems with a rebreather (hypoxia, hyperoxia, hypercapnia) and brief/demonstrate the appropriate action for each.

at the bottom of this page on the bsac website:

Rebreather FAQs - BSAC

David.

To be honest I think a rebreather divers buddy ought to havea bit more than just a briefing prior to the dive, perhaps it ought to be a course in itself?

Huh?
The differences are minor - a diver with a problem needs gas, a lift or both.

If my rebreather is irreparably broken stuff a reg in my face and we thumb the dive. I have two spare regs for just that but others might not.
If I loose the plot totally lift me reasonably quickly.

I show them two items above and beyond 'the usual' buddy check.
1) This is how to close the loop. If it is out of my mouth do this.
2) This reg is pure oxygen. At depth it is death. Anyway it has a shut off on it so grab one of the others if you have a problem.

Don't push any buttons, don't turn any valves, don't mess about doing anything you didn't learn doing lifts on Sports Diver/Rescue Diver. It's no good knowing about hyper this or hypo that as the only two things you can do are donate and lift. Speed is, as ever, of the essence.

Interesting stuff....

I'd read the FAQ's on the BSAC site and thought they were a bit weak, especially if diving with someone with no knowledge of the unit.

CLearly they don't need to be expert but the 'mistique' of arebreather can be quite daunting to those with limited experience or not knowing anything about the technology at all.

MOD1 and the manufacturers hand book covers some of the issues; I was interested, as I mentioned, if there was anything SPECIFIC to BSAC.

How does the BSAC MOD1 say for the Inspo cover this?

pm Nick Kay he might shine some light on it.

The only thing I think is BSAC specific is the insistence that the built in 3L of Diluent is not enough to bail out a buddy so you are expected to carry additional gas.

I clip on a 3L of air so I have something to hand off if diving with a traditional BSAC 'guy on a single'. I wouldn't want to try and donate my AutoAir although it's a good breathe as if I push the wing dump button it dumps through the mouthpiece so unless they happen to be inhaling nothing much will happen. I think the rest is pretty much as taught by other agencies.

My MOD1 was IANTD not BSAC, but I do know my BSAC onions.

I don't think there's anything that is specific to BSAC that I wouldn't say to someone from another agency.

Basically I show them how to switch me to OC (easy with the BOV). Tell them that the O2 inject is NOT a BC inflate (hard to get confused but you never know), and that if I'm behaving funny, they should put me on to OC and we're going up.

I tell them that I have a side slung stage that is there for them. Either you or the OC diver must have suitable bailout available. As I don't dive aplinist I always do.

Is there anything that's niggling you?

Niggling.... not really, just preparing for club dives and second guessing some of the issues likely to arise.

I agree that from the technical stand point there shouldn't be anything different from agency to agency, but there are quirks re: club diving, DO responsibilities, buddy pairing etc. All of which is covered on the BSAC site.

As I didn't train on the unit with BSAC either,I was wondering if I'd missed anything specific to club diving that might have been covered in the BSAC MOD1 or else where on the website.
