Dude was wearing a 20lb chain while his wife was getting an MRI.
She freaked, and yelled for him, and he ran into the room while the machine was still on and fucking died.
This is 100% their fault, I could almost see an argument that the door needs a lock to prevent idiots with 20l s of metal around their neck from running in, but you don't want to lock everyone out in case there's an issue.
