Should have been safe, if missed, no? Not a plethera to cook off

in an uncontained manner?

It likely would have been safe. In fact, my 135 certificate allows for
carriage of oxygen generators on passenger planes if they are in an approved
medical device like the one I found. However, most airlines don't allow it.
If the airline did allow it, the PIC should have been notified of the hazmat
and it should have been labeled, packaged, and secured as such. TSA didn't
flag it. They let it get thrown in with the rest of the baggage.

Last week, I had another hazmat problem albeit not TSA's fault. The baggage
handlers put an electric wheelchair in the forward cargo compartment. It
wasn't a problem until they laid it on it's side without securing the
lead-acid batteries. The batteries fell out. There was a leak-proof battery
box with a diamond shaped hazmat sticker provided by the airline next to the
wheelchair. It contained a battery charger. I just shook my head and cursed
the stupidity of the world.

Are all U.S. carriers now up to these regs?

For passengers, yes. The cargo guys have detection, but I'm not sure where
they stand with suppression..
