Safety Devices Interlocks

Interlock switches are used to prevent inadvertent access to the beam. They should not be bypassed. Interlocks should be checked periodically to insure that they are functioning properly. Interlocks and other safety devices, including warning systems, are not foolproof or fail safe. A safety device should be used as a back up to minimise the risk of radiation exposure never as a substitute for proper procedures and good judgement.
