R 333.5448 Accelerator controls and interlock systems.

Rule 448. (1) Instrumentation, readouts, and controls on the accelerator control console shall be clearly identified and easily discernible. (2) All entrances or openings into a target room or other high radiation area shall be provided with interlocks. (3) When an interlock system has been tripped, operation of the accelerator shall only be resumed by first manually resetting controls at the position where the interlock has been tripped, and lastly at the main control console. (4) A safety interlock shall be on a circuit which will allow it to operate independently of all other safety interlocks. (5) A safety interlock shall be fail safe. A defect or component failure in the interlock system shall prevent operation of the accelerator. (6) A scram button or other emergency power cutoff switch shall be located and easily identifiable in all high radiation areas. This cutoff switch shall include a manual reset so that the accelerator cannot be restarted from the accelerator control console without resetting the cutoff switch.
