Safety Approval


For safety approval you will need to contact the scientist responsible for the technique that you are interested in (see Contacts list on the right side of the page).

An ESAF (Experimental Safety Approval Form) is mandatory for each and every experiment performed at the APS. These should be submitted at least ten days before the experiment is due to commence. Failure to do this could delay the start of the experiment – wasting valuable beam time in the process.

ESAFs must be submitted electronically via Web Page with a user login.

All APS-required training must be completed before the experiment can begin. Routine training can be completed at the APS Remote Training Web Site.
