|Complete Experiment Safety Documentation|
The steps for authorization of your experiment are described below.
Prior to Your Arrival at the ALS
If you did not submit a General User Proposal, you must submit an ESS one month prior to arrival at the ALS.
2. Biological, Radioactive, Hazardous, and Electrical Materials, and Lasers
If your experiment involves the use of any of the above materials—no matter how small the quantities are or how innocuous the sample may be—additional authorization may be required. Please submit your ESS early and clearly identify your materials. Our staff will assess the hazards and contact you about any necessary supplementary documentation.
4. Experiment Coordinator will contact you
Upon Arrival at the ALS
On the outer wall of the ALS at the appropriate beamline sector board you will find a paper copy of the ESS plus any other required documentation in the plastic ESS holder.
6. Check the ESS for accuracy and have all participants sign on final page
The ESS also needs to be signed by subject matter experts, depending on the hazards, and finally by the Beamline Scientist to authorize the experiment. No work should be done until the ESS is authorized.
7. Changes to an Experiment
At this stage, any changes to the experiment, including sample materials, hardware, or personnel must be documented on a Functional Change Form. Please notify the Beamline Scientist or Experiment Setup Coordination any time you need to make a change.
8. User Experiment Form (UEF)
The UEF (to be placed in front of the ESS) also needs to be completed and signed by the participants, and initialed by the beamline scientist. This form provides "real time" experiment information i.e., dates and times when the work is being performed, participant contacts and possible experiment hazards.
9. Final Experiment Approval
Once all documentation is signed, and the ESS and UEF are posted, the experiment may proceed.
During the Experiment
All work must be carried out following the hazard controls identified in the ESS and with appropriate Personal Protective Equipment (PPE) for the type of work and for the area where the work is being performed.
