Emergency off

The Emergency Off button is located on the wall next to all computer equipment and next to the MR magnet room doors and on the MR system Main Disconnect Panel (if provided). It removes ALL electrical power from ALL components of the system, including any power sources from uninterrupted power supply (UPS) devices.

The Emergency Off button not only stops a scan in a patient emergency, but also in the event of a serious equipment fault or hazards such as fire/water in the vicinity of the MR equipment. The entire MR system is to be turned OFF except for the static magnetic field and the magnet rundown unit used to shut down the magnetic field.

Use this button only in a major emergency in the computer or MR magnet room. For example, use this button when you notice fire, sparks, or loud noises not associated with normal operation of the system.

Note: To restore power after emergency off, the main circuit breaker must be reset before rebooting the system. Always contact a service engineer before restoring power.

Warning

The Emergency Off button does not turn off the magnetic field. To avoid personal injury or equipment damage, do not bring any ferromagnetic equipment into the magnet room. Assume that equipment is magnetic unless it is clearly labeled otherwise.
