Emergency Power Shutoff

When should I use the electrical power emergency shutdown button? 
Use the emergency power shutdown button when there is a fire in or near the MRI rooms, or if there is damage to the scanner that can be prevented by shutting down the electrical power (Note: shutting down the electrical power does not remove the magnetic field).

How do I shut off the electrical power to the scanner in case of an emergency? 
You can shut down the power by pushing the red triangle button on the keyboard or on the front of the magnet next to the bore entry. 

Or you can push the red buttons behind the plasic cover on the wall  inside the control room (next to the control room door) or inside the manget room (right next to the control room door).  These buttons will shut down the main transformer and  cut off electrical power to the entire MRI system. 

What do I do after I use the emergency power shutoff? 
Please do not attempt to turn the power back on by yourself. Instead, report your use of the emergency power system to CFMRI technical staff.
