TBF, If I saw a big red button labeled stop, I would have pressed it in that scenario, most emergency stops don’t destroy the entire system.
You would have pressed it to retrieve a personal item? Seriously? Like if you're visiting a factory and your phone fell on the assembly floor you would run to the first red button you could find and press it without asking anyone? If so, please never get on an airplane.
I’m wondering the timeframe. Did the gun SWOOSH out of his hand and then he slammed the button right in front of him worried the gun was going to explode or something?
What’s unforgivable is cops in LOS ANGELES even using one penny of taxpayer dollars to even think about cannabis. I guess they’re protecting state coffers - illegal buds = no tax revenue.
I’d want them to respond to complaints about growers near schools or something… and try to be proactive I suppose if a residential neighborhood reeks…
But reviewing all business power consumption and going on fishing expeditions WTF?! In LA?!?
Like my redneck ass town wouldnt consider that enough due to the amount of folks qith home machine shops and specialist equipment. But somehow LA isn't supposed to have that.
I mean... I kind of get it. The personal item happened to be a fucking gun. One with moving parts that will fire bullets if the wrong part moves. Your phone will not fire bullets. Seems kind of prudent to stop the machine with spinning magnets and wildly fluctuating magnetic fields from operating near a rifle that may cause it to fire.
I guaran-fucking-tee you that if they hadn't shut it off, and the machine caused the firing pin to trip resulting in a bullet being fired and hitting someone, people would be saying "what stupid cops let the gun just sit there when they could have hit the emergency stop switch!"
However, the main issue is the rifle never should have fucking been there in the first place!
Cop gets the gun by destroying the machine: cop is dumb
Cop doesn't get the gun and someone gets shot at: cop is dumb
Moral of the story: cop is dumb
If it was me, i would ask the people there how to retrieve my stuff.... I might get into trouble but hey in this scenario im a police who lose their gun to MRI machine so I'll look stupid either way
The people there were probably handcuffed on the floor and not in a mood to help.
With the benefit of hindsight we all would.
Also, the benefit of common fucking sense to ask the professionals before just hitting an emergency button when there's no immediate danger.
The ones I'm familiar with don't say stop on them and they have a plastic guard over them to make you be really sure you want to hit it. It also causes damage to our tools (giant electron microscopes) because it has to make itself safe instantly, which means neutralized a lot of electricity, various gasses, and mechanical parts in an instant.
But it's also not unusual that E-Stops can cause severe damage to a machine when used. After all, such switches are meant to instantaneously bring everything to a screeching halt for safety reasons without worrying about the machine.
And in this case, the E-Stop is meant to prevent the MRI from exploding and sending pieces of shrapnel flying everywhere. MRI machines can be quite dangerous in operation.
MRI machines don't explode and send shrapnel everywhere lmao.
The quench button is used if a person is pinned by a ferrous object, or if there's a large fire in the room and firefighters need to get in the room.
The electrical E-stop button is used if the equipment is on fire, or if there's flooding.
MRI machines do explode and send shrapnel everywhere. Emergency stopping them causes the helium that's trapped in the part that rotates the magnets to become a gas, then expand as the magnets superheat. In some cases, this causes an understandable explosion.
Seriously happened once already this year https://healthimaging.com/topics/medical-imaging/magnetic-resonance-imaging-mri/mri-explosion-leaves-3-injured-including-2-hospital-staffers , the cop is lucky.
The magnet doesn't rotate like a CT. But you're right that there is a vessel with supercooled helium.
But that's the first time i've ever heard of this... It's a philips, makes sense.
They're supposed to be designed such that it is impossible. Looks like there was a major recall. Because again, that's something that should never happen.

Just a small handful from a very fast search. Feel free to look for more with photos of the damage.
Not sure why you are downvoted. I think a rifle getting pulled into an MRI machine is as good a reason as any to hit the big red button.
I agree, imagine if you were just sitting around figuring out what to do and the gun went off in the MRI possibly killing someone. The mistake was entry in the first place, not this
