2. Call 112
3. Call 2222 and ask for BHV assistance.
   Try to determine whether or not evacuation from the scanner might (further) hurt the person.

Question 5

Procedure for (spontaneous) quench

Answer 5

With subject in scanner:
check for signs of helium in the room to determine whether it is safe enough to enter yourself and evacuate the subject.
- low oxygen percentage
- white clouds
- ice crystals

Without a subject in the scanner:
leave the scanner room.

In the very rare occurrence that the helium does not flow out through the quench pipe but enters the room:
1. DO NOT enter the scanner room and leave the door closed.
2. Notify ERO personnel
3. go upstairs and wait outside. ERO personnel will evacuate the affected zones.

Question 6

Procedure if object gets stuck to the magnet

Answer 6

1. Abort scanning
2. alert MRI staff
3. if applicable evacuate subject from MR scanner room.
   Do not quench the magnet! If necessary, Philips will remove the field gradually, preventing loss of helium and potential damage to the magnet.

Question 7

Procedure if subject presses the alarm button

Answer 7

1. Abort the scan.
2. (a) Responds after contacting via intercom: ask whether to stop experiment or not. (b) No response after contacting via intercom: start scanner evacuation procedure

Question 8

what to do in case of doubts regarding subject compatibility

Answer 8

Ask the MRI staff, specifically the MR safety officer.
If the MRI staff is absent you can check mrisafety.com for extra information
In case of absence of the safety officer: your subject must be excluded.

Question 9

The latest procedure and protocol can be found on the MRI Teams page. If you cannot find it, please contact the MRI staff.

Question 10

Scanner evacuation procedure

Answer 10

1. Remove the table with the subject from the scanner (unless he or she is trapped) using the manual table button.
2. Contact ERO personnel to help you decide whether to remove the injured person from the scanner room (in case of e.g. possible back injuries, the ERO may decide to leave the person there until emergency personnel arrives). In case the person needs to be removed from the scanner room, ERO personnel will help you carry the person from the scanner room using the rautekgrip.
3. If the subject cannot be removed from the scanner room, the MR Operator has to make sure no one (including ambulance, hospital personnel etc.) can enter the scanner room without having been screened.
4. If necessary, call 112.
5. If necessary, call 2222 with the fixed phone on the desk to reach emergency services. You are in building REC L (control room: LK.03). Stay with your subject in the MR control room. They will start the BHV procedure.
6. If possible, let one person stay with the participant. Also while calling 112/2222. If possible, one person stays at the front door to welcome emergency personnel.
