Surely you'd hit the quench button straight away? I cannot imagine policy being "check if the victim is dead, and if not hit the button."
I also wonder what the field decay is like. If it takes 15s and it's linear it's much worse than if it's 15s but decays exponentially. You don't need to field to be gone, you need the field to diminish enough to stop strangling the poor guy.
- potato3732842 1y agoTakes more than 15sec to strangle someone. 30 shouldn't cause any serious damage beyond whatever mechanical damage there is from being tugged around. Heck, 2-3min is probably fine if the MRI is located at a hospital. Edit: Per the article that I would like to remind everyone is well worth reading, he had time to say goodbye to his wife, that would seem to me to imply he wasn't tossed hard enough to be incapacitated.
- baq 1y agostrangle? dude's neck was probably crushed. if I had to guess this was a near decapitation, not a strangling.
- close04 1y agoCausing severe head trauma or crushing the trachea can be almost instant. A lot of the more serious MRI related injuries are objects flying across the room and hitting someone, especially over the head.
- strken 1y agoPer the article, his wife claims that he had time to wave goodbye to her. A man getting dragged by the neck and hitting an MRI machine head-first is going to make all sorts of hand movements that his grieving widow might interpret as waving goodbye in hindsight.
- egberts1 1y agoAt distance-sqaured law, he literally accelerated beyond 16 G-force (gravity) and slammed against the machine surface.
- egberts1 1y agoWith 3,200 lb/ft forces inches away from 1.2 tera-gauss magnet, all damages were already done to artery, veins, tendons, muscle, by the 20 lbs necklace, all beyond surgical repair.
- zdragnar 1y agoIn this case, he died after being removed from the machine and taken to a hospital. The damage was likely done almost immediately; a heavy 20 pound "necklace" is going to apply a lot of crushing force.
- Filligree 1y agoAnd for the other readers: It wouldn’t be applying twenty pounds of force, it would be applying… My rule of thumb calculation came to 3,000 lbf, which seems like a lot, but perhaps that’s actually accurate.
- potato3732842 1y agoSeems spot on to me. Figure half that to start since most of the loop is gonna wind up laying flat and only the half of it is prevented from doing so by one's neck. Then maybe cut it by 2/3 again since the sides aren't gonna do a ton of direct squishing. That still leaves you with hundreds of pounds, which roughly aligns with the timeline of suffocation in the article High hundreds low thousand likely would be neck snapping or otherwise instantly incapacitating.
- Doxin 1y ago> The damage was likely done almost immediately; Not disagreeing, just saying the tech running the machine couldn't have known that and should have quenched the machine in case the damage was survivable.
- mvdtnz 1y agoRight. You - a person who wasn't there, has had no training, has seen no photos and doesn't understand any of the details of the circumstance - are certainly better positioned to know that than the trained staff who were present.
- Aeolun 1y agoThe article says 1hr before it was turned off. That’s long enough to start questioning.
- DebtDeflation 1y agoYou're in luck. Video of an MRI magnet being quenched that I posted above: https://www.youtube.com/watch?v=9SOUJP5dFEg https://www.youtube.com/watch?v=9SOUJP5dFEg
- jpgvm 1y agoYeah so this video shows exactly what I am talking about, the chair and other objects don't fall immediately, it takes ~15s for them to drop to the ground after the quench starts.
