What if you forget to deflate your bcd on ascending?

[larryjoe]

Any stories or damage reports? I'll probably only be down to 40' mostly, hope I don't forget. I have only been on 3 dives. I'm guessing a big bang.

Well you might want to make sure you have your DAN current and the number close by......uncontrolled ascents are usually not good. People have died doing ascents in a swimming pool.

Your lungs would pop before your BCD does, if only because your BCD has an OPV (Over-pressure valve).

[rox@ucf11]

yeah but not sure how you would forget, you should be able to tell if you ascending really quickly

[Warren]

It's possible you'll rupture the BC...

More worrisome of course is an uncontrolled ascent.

The shallower you get, the more bouyant you get, and the the more bouyant the BC gets.

It could get ugly fast.

Take time to sit down, and visualize the dive. Ensure you check in with your buddy, give the thumbs-up sign, note the time, raise your BC hose and start the ascent.

Don't forget. Your BC will be OK. You might not.

[comet24]

Most BC will automatically vent if over pressured. Your body will not.

I hope you fully understand not deflating as you ascend will cause an out of control assent and can cause serious harm to your body. From 33 feet to the surface any air in your BC or your body will double in size.

Overpressure valves are built into bc's to avoid this type of damage to themselves... Properly weighted, you shouldn't have enough air in your bc to cause a runaway ascent because you didn't dump enough air from 30-40 feet, however, if you do not vent enough air, it is still always a possibility, and should really be second nature - you should do it without really even thinking about it...

If you want to end it all, you won't be disappointed.

A naive query after OW certification.



Get with an experienced diver and review the basics, before your next dive.

Breathe; keep your airway open; if you are ascending more rapidly then you'd like, immediately make sure you've dumped all air from your BC and you can flare your body to slow the ascent. You'll very, very likely neither damage your BC nor injure yourself - but there is a risk as others have pointed out (more strenouously than I think is realistic). Get into the habit of always beginning your ascent by confirming your intention with your buddy and as a first matter dumping from your BC and remaining in a position to dump more as needed.
