This hazard classification applies to all experiments involving hazards not defined in the other hazard classes.  Other hazard classifications and their associated hazard controls may also apply to experiments in this hazard class.

Experiments involving this hazard class are categorized as high risk experiments.  The experiment may be reclassified to a lower risk category dependent upon the review results of the experiment.

Engineered Controls – Dependent on review of new hazard.

Procedural Controls – SOP required as specified in review.

Design Reviews and Equipment Inspections – New hazards must be reviewed by Beamline Management and the APS Experiment Safety Review Board.  Additional review resources at Argonne National Laboratory may also be required.

Training – Defined in review of hazard.

Signs and Labeling – Defined in review of hazard.

Personal Protective Equipment – Defined in review of hazard.

Dosimetry and Monitoring – Defined in review of hazard.

Unless otherwise noted in the approved experiment safety plan, the PSC Deputy Associate Laboratory Director of Operations delegates the authority to authorize an experiment in this hazard class to a member of the APS Experiment Safety Review Board and resident beamline personnel having the authority to authorize experiments as listed in the ESAF system.  Approval by both the host beamline and APS Experiment Safety Review Board are mandatory prerequisites for experiment authorization.

The PSC Deputy Associate Laboratory Director of Operations delegates responsibility for verifying that required controls are in place to the experiment On-Site Spokesperson and Beamline Management.
