"Among the thousands of papers published on nanotechnology, this is one of the first to address the critical issue of how workers who are creating and handling nanomaterials should be trained about the hazards they face - in laboratories, manufacturing facilities, at hazardous waste cleanup sites and during emergency responses. Given the limits in the current understanding of nanotoxicology, workplace exposures and effectiveness of control strategies, defining effective training is particularly problematic. But workers clearly have the potential to be exposed and are guaranteed the right to know about the risks they face, under international hazard communication standards that are being harmonized across the globe."
