Anyone who brings samples to SESAME must first submit a risk assessment. If you submitted a proposal through the SUP, you will have provided sample and safety information at this time. You should respond to the Safety Office’s requests for clarification or further information as quickly as you can. If you are carrying out an experiment by any other arrangement, you must submit the risk assessment form to the Safety Office at least two weeks before the experiment. For any changes to the risk rating of samples you are bringing, you must contact the Safety Office prior to your visit.
The following categories of samples are prohibited at SESAME:
Radioactive samples: Samples with dose rate (DR) > 0.5 µSv/h are not permitted.
Chemical samples: Acutely toxic / dangerous chemicals, unless there is a rigorous sample handling procedure in place.
Biological samples: Any samples categorized as posing a safety risk (Biosafety levels 1-4) without appropriate treatment.
It is expected that all samples that are brought into SESAME will be removed by the user except with the agreement of both the beamline scientist and the safety office.
Any other waste generated by a user should be disposed of in the provided plastic waste bags, with the proposal number clearly indicated. More detail is provided in the waste disposal section.
