Guarded Magnet Quench Button (Emergency Rundown Unit)
This
WILL
drop the magnet.
Depressing the Quench Button will rapidly deplete the
magnetic field. The magnet located inside of Scan Room is cooled by liquid helium. When
the magnet quench button is depressed, the helium will be quenched from the magnet.
This must only be done when there is an emergency related to the magnetic field.
Once this button has been depressed, the helium will be quenched and the MRI
System must be serviced before it can be used again.
The guard must be lifted before the button can be depressed. Once the button has been
depressed, the magnet will begin quenching while all the other systems continue to work
normally.
Manual Shutdown (Emergency Stop / A1 Stop)
This
WILL NOT
drop the magnet.
Depressing the Quench Button, only, will rapidly
deplete the magnetic field. Depressing the E-Stops or A1 Stop buttons will not deplete the
magnetic field. Manual shutdowns are those that require the operating personnel to
depress “Emergency OFF” buttons in the event of an emergency. The “Emergency OFF”
buttons are located in Control Room and Scan Room aboard the mobile unit. When these
buttons are depressed, only the medical system will be shutdown. The trailer systems will
still be operational.
