CHESS has an extensive safety interlock system to ensure safe use of synchrotron radiation. The combination of the interlock system and radiation shielding are designed to prevent exposure to radiation. The system has been designed in a failsafe manner, with redundant components and logic circuitry.

**DO NOT remove or go around a barrier in order to cross an interlock unless a CHESS Operator has instructed you to do so.**
Radiation Safety Shielding:
In various places throughout CHESS work areas, including inside hutches, there are permanently mounted radiation safety shields made of sheets or blocks of lead.
While it is acceptable to modify temporary radiation shielding on detectors involved in your experiment,
do not modify or tamper with permanent safety shielding in any way. If you have any questions or need any changes made to the configurations in your hutch, contact the CHESS Operator.
Outside of the experimental hutches, barrier walls provide effective radiation shielding. However, keep in mind that
if you need to use a ladder, ask the CHESS Operator for permission first, and do not climb above the level of the shielding
wall - safety shielding is not designed to be effective above
this height.
