Whereas diving a while in the past, I overheard a close-by group going via the BWRAF (BCD-Weights-Releases-Air-Remaining verify) predive security verify. At “A” — Air — they checked valves open, check breathed, AAS location, and so forth. and: “I’ve acquired 2900.” “Okay. I’ve received . . . WHAT? 300?” After double checking the cylinder valve, the workforce decided they’d confused an empty with a full, swapped, rechecked and had a terrific dive.
The purpose is that because of utilizing BWRAF – a guidelines – a minor annoyance stayed a minor annoyance. If the staff had gone in with solely 300 psi, hopefully they’d have managed, however it will have been a much bigger drawback that didn’t should occur – probably a big incident. Sadly annually, dive incident reports embrace leisure diving incidents that possible wouldn't have occurred if the divers concerned had merely carried out a predive examine and used a guidelines. That is value remembering as many people return to diving following an extended break.
It’s not simply diving, in fact. Astronauts, pilots, surgeons, particular forces, nuclear engineers and the-list-goes-on use checklists. However, if we’re self-honest, we don’t actually need these examples, nor any of the many formal studies that present checklists work to know we divers ought to use them, too. We’re human, so screwing up isn’t doubtless – it's sure. We'll overlook, overlook, omit and fail-to-say – lists assist remind us to recollect, observe, embrace and talk. As surgeon Atul Gawande – writer of The Checklist Manifesto: How to Get Things Right and probably the world’s main skilled on surgical checklists – places it, “Checklists appear lowly and simplistic, however they assist us fill in for the gaps in our brains and between our brains.”
Remember that as an exercise turns into extra complicated so does the error potential, which is why whereas BWRAF is suited for mainstream recreational diving, it’s not essentially what you employ in tec diving – CCR (Closed Circuit Rebreather) diving particularly. In reality, following a two-hour dialogue amongst diving’s prime specialists at Rebreather Discussion board three in 2012, the first two consensus points to enhance CCR diving safety have been utilizing checklists. There are various extra methods for us to screw up, which is why checklists for most of these endeavours are extra in depth and written.
One other anecdote: As splash time neared on a reasonably full dive boat, divers hurriedly geared and lined up, ready for the divemaster to clear everybody to large stride in. Amid the clamor, an virtually timid lady’s voice – simply loud sufficient to be heard – floated over addressing her buddy, “Wait. What about our [safety] checks?” The whole boat went quiet. Then, virtually embarrassingly, each buddy staff – seasoned instructors to freshly-certified novices – commenced uncared for checks.
So, if it ever looks like there’s social strain to skip checklists and predive checks, converse up. Doubtless, plenty of individuals round you may be relieved by the reminder that divers are not too cool to do checks and use checklists.
