The ESAF consists of two parts: the Experiment Authorization Form (EA) and the Experiment Hazard Control Plan (EHCP.)

The EA form lists general information such as the experiment PEN and ID numbers, experiment start and end dates and times, On-Site Spokesperson, Safety Review and Approval for both the beamline and APS, brief material and equipment hazards listings, and final Safeguards Verification. This form gets posted in the beamline endcabinet.

The EHCP form gives a more detailed explanation of the experiment, including some information from the EA form. This form gets posted on the experimental station door where the experiment will be running. This form additionally lists:

• the materials to be used in the experiment, their quantity, and any hazards associated with the materials
• equipment and physical hazards with full experiment description
• hazard classes that apply
• equipment safety requirements summary
• beamline comments with risk class
• APS Experiment Review Board comments
• experiment personnel list and APS core training due dates

The ESAF form is generated in electronic version by the XSD and CAT staffs. The details of how the form is generated, and the experiment review process, are not of direct concern to the FC. Nevertheless, there are several administrative aspects that do directly involve the FC. They are discussed in the following procedure which should be read at this time: Instructions for Posting of Experiment Authorization Form/Experiment Hazard Control Plan The reader is also likely to find the following link regarding ESAF electronic submittals helpful:
