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?

Hello! Welcome to Earth. Can you please show us this device you speak

NOTHING is foolproof. One cannot prepare for every possibility, we just

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?

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?

The point was the thing you're missing right now... DIFFERENT systems for
different situations.
We were discussing CO2 scrubbers, oxygen systems and air systems... you
brought in a "device" that lasts an "hour" that they "carry"...
Kinda threw a wrench in the train...
That's all...
No big deal....

Oh, and the spare air thing.... It's a cu.ft. calculation... the product
specs say 57 breaths at 1.6L per breath....
However being that the average tidal volume is only 600cc, makes their specs
quite open to interpretation.... Might last 10 minutes, might last 18...
THAT was the point.
