Currently, there are no nanospecific safety data sheets (SDS) fo r manufactured nanomaterials (MN) and there is only limited data available on nanomaterial exposure levels. We have established an advanced control banding tool, NanoSafer, which enables alternative risk assessm ent and guidance for safe use of MN based on first order modeling. The hazard and case specific exposure as sessments are combined for an integrated risk evaluation and final control banding. Requested material da ta are typically available from the producers’ technical information sheets. The hazard data are given in the SDS for the closest analogue bulk material for which the requested occupational exposure limit (OEL) is given as well. The emission potential is either given by a constant release rate or the dustiness level determined us ing the EN15051 rotating drum or similar. The exposure assessment is estimated using the work room dimensions , ventilation rate, powder use rate, duration, and calculated or given emission rates. The hazard sc aling is based on direct assessment. The exposure band is derived from estimated acute and work day expo sure levels divided by a nano OEL calculated from the OEL of the nearest analogue bulk material a nd the specific surface area. The NanoSafer control banding tool is now available in Danish and English and contains help tools, including a data library with dustiness data and an inspirational nanosafety e learning tool for companies’ risk management. The ability to construct user specific work scenarios for exposure assessment is considered a highly versatile approach.
