Nanomaterials and Biosafety 101 is a new webinar that aims to introduce participants into the safe handling of nanomaterials in laboratories. This webinar will provide an overview of common nanomaterials and their uses, hazard properties, potential for exposures and approaches for minimizing risks of nanomaterials in laboratories. It will help safety and health professionals and researchers from academia and industry to identify nanomaterials and to develop site-specific guidance for safe handling of nanomaterials. This webinar is suitable for professionals who are unfamiliar with nanomaterials as well as those who are interested in learning about most recent developments in the safety of nanomaterials. The webinar will be taught by an internationally recognized expert in nanomaterial safety who leads efforts in this field in International Organization for Standardization, Organization for Economic Cooperation and Development, and United Nations.
