Yeah. This is a Bad Thing.
Apparently he took it off and tried to lay it onto a cabinet. Just a lllllittle too close...

It takes days to die from oxygen poisoning.
Why did they leave him in there for days?
O2 bottle is never supposed to enter the scan room
Darwin Award. He should have known not to go into the room with anything metallic.
Prison guards have to leave their guns outside the room when escorting an inmate patient into the room.
They will ask and let you know the later you may feel a warming and tell them if you’re t gets too bad
Was a famous case in the community in NYC where a cop refused to check his gun walked into the room and it was yanked out of the holster and discharged. Luckily no one died
Yes. Breathing 100% oxygen does NOT cause a pneumothorax. In fact high oxygen concentrations are used to treat small pneomothoraxes without operative intervention
If ze is gender fluid ze can be anything.
When I did anesthesia for MRI we had aluminum O2 tanks. Our Anesthesia machine was designed for MRI machine use. You have to get fairly close to the MRI machine with magnetic material to have a problem. Once you cross that point the magnetic object is buried in the machine. There are you tube vidios of people placing metal objects into MRI machines. They can be pretty entertaining. MRI machines can also “quench”. The electromagnets are cooled by liquid nitrogen. If the cooling apparatus fails the MRI machine will release nitrogen in a rather dramatic fashion. MRI rooms have O2 monitors so if a nitrogen leak reduces O2 levels the staff will be earned. Look up metal objects MRI and MRI quenching.

One source mentioned liquefied gas; but, failed to distinguish whether an oxygen or helium cryogen was the culprit.
I’ve worked med devices for about 18 years now (manufacturing, supply chain, etc). 12 of it was for GE mainly in MRIs
The stories I’ve heard about inadvertent quenchings, metal taken in the room, etc
Then there was a guy - I think in Brazil - that disabled an auto shutoff to run some test scans - left the place unattended and the body coil overheated to the point the epoxy caught fire. Lost the whole suite - managed to save the rest of the building though.
Here’s a veterinary version that didn’t have a proper setup for Helium boil off, over-pressurized, and exploded: http://www.dailymail.co.uk/news/article-2983440/One-man-fighting-life-two-injured-MRI-machine-exploion-New-Jersey-animal-hospital.html
There was one in India where they found the emergency quench wasn’t even wired.
Between the cryogens, magnetic field, high voltage, and potential pressures the things can be very dangerous if not installed, maintained, and operated properly.
That sucks.
That’s the one... my understanding is he was directed to put it in the provided lockable locker outside the room, but took it into the room anyway.
Only way to remove it at that point is to ramp down the magnet - I can’t remember for sure how long ramping down and back up takes, but it isn’t a very quick process ... want to say on the order of a day or so each way... but I may be thinking of the helium fill... been a few years and I never really worked the service side.
Thank you for sharing.
I have no knowledge of MRIs but a year or two ago I thought I read a thread here on FR that MRIs have some kind of emergency dump system to kill the magnetism very quickly if needed.
Yes that’s called an emergency quench - but if you do it you vent all the helium in the magnet and blow out the safety. Very costly, very long time to recover. You can ramp down gradually without losing all the helium - though you still lose some- and you don’t lose the safety either.
Theres something being lost in translation. He didnt die from too much oxygen IN his lungs. He had a pneumothorax. Apparently the force of being dragged in, or impact from the flying bottle, hit him hard enough for the lung itself to pop. The gasses leak out and are trapped BETWEEN the lung and the pleural sac. The lungs are compressed and collapse under the pressure.
Not turned to steel in a great magnetic field.
And where is Ward Cleaver.
Who shouldn’t be so hard on the Beaver...according to his wife.
