6.1.1 Instrumentation, readouts, and controls on the particle accelerator control console shall be clearly identified and easily discernible.
6.1.2 Accelerator controls shall be equipped with one or more of the following:
6.1.3 Each entrance into a target room or other high radiation area shall be equipped with multiple safety interlocks that shut down the machine under conditions of barrier penetration.
6.1.4 Each safety interlock shall be on a circuit which shall allow it to operate independently of all other safety interlocks.
6.1.5 All shielding that is temporary, movable, or detachable shall be interlocked.
6.1.6 All safety interlocks shall be designed so that any defect or component failure in the safety interlock system prevents operation of the accelerator.
6.1.7 When a safety interlock system has been tripped, it shall only be possible to resume operation of the accelerator by manually resetting controls at the position where the safety interlock has been tripped and, lastly, at the main control console.
6.1.8 A scram button or other emergency power cutoff switch shall be located and easily identifiable in all high radiation areas. Such a cutoff switch shall include a manual reset so that the accelerator cannot be restarted from the accelerator control console without resetting the cutoff switch.
