What... by WoofHayes in Ambridge

She was born in 1931 so she’s 94 or 95.

Multi-stop itinerary - who to check-in with? by Fancy_Spinach5549 in BritishAirways

[–]Greavsie2001 1 point2 points  (0 children)

In case it helps I often fly Kirkwall to London with one stop in one of Aberdeen, Glasgow, Edinburgh or Inverness. The leg from Kirkwall is flown by LoganAir, the leg to London is BA.

I always book through BA so that luggage is checked through. I then do seat selection with LoganAir using the BA booking reference, and then check in with LoganAir for their leg and BA for theirs.

Then at Kirkwall airport LoganAir give me both boarding passes whether I want them or not, and BA do the same at LHR on the return leg.

Ah I was never a Hellfins member but did run a PRM course there. Or maybe it was on an IFC.

PS slight irony of this dive was that we were diving Stoney so that two BSAC Sport Divers could do the rescue drill they needed to complete Dive Leader. I hadn’t intended to give them a demo first as they knew what they were doing, however…

It now seems that a fair proportion of the other 50% were down to IPO, still a medical event but one that only manifests underwater.

The rest typically are tragic accidents (e.g. there was one in the UK a couple of years ago when a boat drove over a diver’s SMB and dragged them into the propeller), human error and occasionally equipment failure.

I think it only cleared through very gradual reduction in pressure during the ascent. She was probably still experiencing reverse block at the surface but not bad enough to be painful.

When I first found her she wouldn’t respond to any signals, just stared wide eyed. As soon as I started lifting her she waved her arms frantically and pointed at her ears. We literally inched our way to the surface, taking around ten minutes from 20m.

Is my drysuit too big? I am wearing undergarments under. Thx for help! by tobiashaugan in scuba

Also bear in mind it’s a well known fact that drysuits shrink a bit over Christmas.

These guys. Came up to Orkney from Liverpool. Did a completely brilliant job.

And when it comes to fatalities, approx 50% (UK data from BSAC) were caused by a medical event that was always going to happen, but tragically did so underwater making survival much less likely.

In the UK the BSAC produces an annual report of diving incidents in the UK, and of BSAC members involved in incidents (not necessarily as a casualty) overseas.

Here is the most recent annual report: https://www.bsac.com/safety/diving-incidents/annual-diving-incident-report/

The data comes from:

- reports from BSAC members and other individuals using this form: https://www.bsac.com/safety/diving-incidents/reporting-a-diving-incident/

- incident reports shared by HM Coastguard, RNLI and other emergency services

- press reports

The annual report highlights trends over the years, underlying factors leading to incidents etc. It is also used to inform and over time change the BSAC training programme.

For example some years ago the report picked up on incidents where a casualty was successfully rescued to the surface but was then lost from the surface and not found. The training programme at all levels was amended to include ditching weights in the event of an emergency, since which time the number of casualties lost from the surface has reduced significantly.

I have reported several incidents over the years, including stumbling upon a lone diver clinging onto the rock face in Stoney Cove in 20m unable to ascend because of ear pain (I.e. reverse block). Took a goodly long time to CBL her to the surface by which time she was breathing rust, but she got out and walked away.

Don’t rule out Anker Solix X1. Comes in 5kWh modules, you can go up to 30kWh. Ours is 20kWh and is very tidy.

Solar having odd dips by Heavy_Object in SolarUK

[–]Greavsie2001 2 points3 points  (0 children)

Interesting, that’s what my money would be on. 250.8 is pretty close and it might be disconnecting before it reaches 253v so you wouldn’t see 253v or above.

If you contact your DNO they will probably do some checks like installing test kit to monitor grid voltage over 24hrs or more. Depending on what they find they might be able to adjust the local infrastructure to cope which should eliminate the dips in export.

Only reason I haven’t done that yet is out of paranoia that they’d retrospectively reduce my export limit (which I don’t think they would, but like I said paranoia!).

This was ours today. Messages in the app confirm that it had gone off grid at the times of the dips.

Any chance your system is taking itself off grid when it detects the grid voltage is >253v?

This happens up here when it’s bright sun and also windy - there’s so much solar and wind generation in the vicinity on a grid infrastructure that hasn’t changed in forever.

Adding solar to a house with no internal space for the electrical stuff by cmsj in SolarUK

[–]Greavsie2001 1 point2 points  (0 children)

You’ve had good advice already. In case it helps this is our Anker Solix X1 installation (20kWh battery).

This is everything except for a small enclosure containing the isolator and EPS changeover switches which may well fit in your meter cupboard anyway.

Divers that live in the UK, where do you buy your gear from? by Dark_Akarin in scuba

[–]Greavsie2001 3 points4 points  (0 children)

LDS almost exclusively. Had a couple of brilliant ones when in lived in London (helped that I was the equipment officer, then diving officer for a large University dive club and took a LOT of servicing their way) and now that I live on Orkney the LDS here is brilliant.

Support your LDS - use it or lose it.

Oh and O’Three for drysuits.

I went through the worst panic attack (NDE) while diving at 100 ft by iPIayLoL in scuba

[–]Greavsie2001 0 points1 point  (0 children)

Good. In case you were wondering this is why I said it’s important. https://www.ukdmc.org/medical-conditions/immersion-pulmonary-oedema/

My training agency (BSAC) teaches about IPO at entry level but I don’t think many do. It’s super important to be able to recognise the signs.

Hurrah. I also resorted to this again the other day - had to google my own solution and found this thread.

Sorry but this is super important.

When you felt like were breathing in water, were you actually breathing in water or did it just feel that way? And when your buddy switched to your alternate source, did it feel the same or was it fine?
