The APS Experiment Safety Review Board (ESRB) advises the PSC Management on the safe implementation of experiments performed by APS users on the experiment hall floor.

The ESRB reviews each experiment that is submitted to the APS via the APS Experiment Safety Assessment System (ESAF). These experiments are conducted in beamline end stations in the APS Experiment Hall.

After an experiment is submitted to the APS Experiment Safety Review system notification is forwarded to the APS and the appropriate beamline. The flow of the safety review is as described in the latest revision of the “APS Beamline Experiment Safety Reviews" section of the "APS User Safety Policies and Procedures”, APS_1258430.

The ESRB (either the whole ESRB or individual members) reviews each experiment to ensure that they:

• Adequately (in sufficient details) describe the experiment
• Identify all significant risks to personnel and the environment
• Define a hazard control strategy satisfying ANL requirements and designed to reduce risks to acceptable levels

If all requirements are met, the ESRB will approve the experiment. It should be noted that approval by the host beamline is also required.

If a member of the ESRB is not available to approve an experiment and/or verify hazard controls are in place (when required) then the approval/verification will be done by the PSC Deputy Associate Laboratory Director Operations or the PSC Director

The ESRB members are appointed by the PSC Deputy Associate Laboratory Director Operations. The current members of the ESRB are:

The ESRB meets weekly during scheduled APS User runs to discuss experiments awaiting approval. More frequent meetings are on an as-needed basis.
