2.2 - Emergency Shut-Off
Where is the emergency shut-off switch and under what circumstances is it used?
The linear accelerator has a number of emergency shut-off switches:
- On each side of the stand
- On each side of the treatment couch
- On each wall of the bunker
- On the entry to the maze
- On the machine console in the control room
- On the power supply to the linear accelerator (in the control room)
The emergency shut-off is activated:
- When there is a danger to the patient requiring them be removed from the room immediately
- If the patient has an acute medical event (eg cardiac arrest)
- If there is a dangerous substance within the bunker (fire, gas)
- If the gantry or treatment head is about to collide with the patient
- When there is danger to a staff member or member of the public who is in the room when the linear accelerator is active
