This online platform allows the different types of workers to be informed about the risk associated with nanomaterials. Depending on the synthesis laboratories in relation to the various types of nanomaterials (graphene, nanowires, nanoparticles), on the risk profile (researcher, student, visitor, etc.) and on the training received, parts of the lab will be highlighted that are accessible based on the different activities (synthesis, characterisation, etc.). It will then be possible, depending on the individual and general protection devices used, to access a section of the site where risk assessment will be shown according to ISO Control Banding procedures, and thus the effective risk resulting from risk analysis through exposure procedures to the nanomaterials used in the various activities (nano safety label).
