Equipment or environmental emergencies

About this task

If you experience a serious equipment fault (system overheating, smoke, or odor associated with the system) or hazards such as fire/water in the vicinity of the MR equipment, you may need to perform a system shut down with the Emergency Off button. The entire MR system is turns OFF with this button, except for the static magnetic field and the Magnet Rundown Unit used to shut down the magnetic field.

Use this procedure to perform an emergency shut down on your system during an equipment or environmental emergency.

Step-by-step instructions

  1. Press the Emergency Off button located on the wall next to the computer equipment or next to the magnet room door.
    • This stops power to the magnet room, removing all electrical power from all components of the system.
    • This button also removes any power sources from UPS devices.
    • For more details, see Emergency off
  2. Evacuate the patient.
  3. Evacuate all personnel from the MR suite.
    • Follow your facility’s emergency protocol.
  4. Call the fire department, if appropriate.
    • When the fire department arrives, evaluate the need for an emergency MRI magnet quench.
    • If the firefighters need to take ferromagnetic equipment into the MRI magnet room, quench the magnet.
  5. Contact a service engineer before restoring power.
    • To restore power after an Emergency Off, the main circuit breaker must be reset before rebooting the system.
  6. After service has examined the system, document the correct cause of the emergency.
    • Documenting the events allows you to reference this information in the future and may help prevent similar incidents.
