I hold a Master Scuba Diver rating and will tell you these things are
not thought of very well in the experienced scuba diving community.
They hold about 3 cft of air. That MIGHT give them 5 minutes of air at
best. Highly unlikely they would have made any difference in this mine
disaster. They were originally designed for military helicopter pilots
that crashed at sea, to give them time to get out of the aircraft and to
the surface.

Yep... seat belts can kill you too, under certain circumstance; but if only
one life is ever saved by this, isn't it worth it?

NOTHING is foolproof. One cannot prepare for every possibility, we just try
to prepare for as many as practical.

You are correct, in a 'trap' situation, spare air [as I said before] is only
a slim chance device. But shouldn't people be given EVERY chance?

[Walk into a black-damp and you'll wish you had one of these for your

I just didn't want to get into the debate that co2 scrubbing would be more
helpful than air/O2 in a 'trap' situation...

They already carry a device which will allow them an hour of air. How
many things do you think they can lug around and still do their jobs?

Hello! Welcome to Earth. Can you please show us this device you speak of???
An internet link perhaps?

Well yeah, that's the obvious first thing to do.... but still didn't find
anything you describe..?

The only [the standard] carry device offers about 30min and it isn't air,
it's a tiny O2 canister with a CO2 scrubber and re-breather bag.

Anything beyond that and it's a shoulder or back pack kept in a central
location, not carried.

Okay, half an hour. You provided a link to something that would provide
an additional--what--minute or two?

What's the point?

I agree nothing is foolproof, however seatbelts, in combination with
airbags have a proven record of dramatic decrease in injuries in a crash
and if there are injuries, a dramatic decrease in fatal injuries. The
facts prove that without question.

No such facts exist for the "spare air". Another poster mentioned they
already had devices that gave them an hour. I was not aware of that.
But I was in the fire service for 27 years. The 30lb SCBA units we used
were rated for 30 minutes and they had 45cft bottles. With a 3cft Spare
Air you can do the math. Even the newer high pressure SCBA's with the
composite bottles at 4500psi are only rated at 1 hour.

My only point is in a situation where rescue operations are spoken of in
"days" instead of minutes and seconds, a 3cft breathing device is pretty
much useless.

I speak volume in litres, not cu.ft. but that other post is from another
