Ariz. Admin. Code § R9-7-908 - Particle Accelerator Controls and Interlock Systems

A registrant shall ensure that:

1. Instrumentation, readouts and controls on the particle accelerator control panel are clearly identified and easily discernible;

2. All entrances into the area that contains the particle accelerator room, target room, or other high radiation area, are provided with interlocks that shut down the machine if an entrance door is opened;

3. If an interlock system connected to an entrance door that provides access to the therapy suite has been tripped, it is not possible to resume operation of the particle accelerator by resetting the interlock switch at the entrance where it had been tripped;

4. Each safety interlock is on a circuit that allows it to operate independently of all other safety interlocks;

5. If possible, the interlock system is fail-safe in design, so that any defect or component failure in the interlock system prevents operation of the particle accelerator; and

6. A scram button or other emergency power cutoff switch is located and easily identifiable in the area that contains the particle accelerator. The registrant shall ensure that the scram button prevents persons from restarting the particle accelerator at the accelerator control panel without resetting the button or switch.
