On January 18, 2013, the National Institute for Occupational Safety and Health (NIOSH) published a Federal Register notice seeking comment on the types of hazard identification and risk management research to consider in updating its fiscal years 2013-2016 nanotechnology strategic plan. NIOSH states that it wants to “build on the accomplishments of ongoing research” to “develop strategic research goals and objectives for nanotechnology occupational safety and health research through 2016.” NIOSH previously identified ten critical research areas for nanotechnology research and communication: (1) toxicity and internal dose; (2) measurement methods; (3) exposure assessment; (4) epidemiology and surveillance; (5) risk assessment; (6) engineering controls and personal protective equipment; (7) fire and explosion safety; (8) recommendations and guidance; (9) global collaborations; and (10) applications. According to the notice, NIOSH is considering focusing the research goals on five key objectives: (1) increase understanding of new hazards and related health risks to nanomaterial workers; (2) expand understanding of the initial hazard findings on engineered nanomaterials; (3) support the creation of guidance materials to inform nanomaterial workers, employers, health professionals, regulatory agencies, and decision-makers about hazards, risks, and risk management approaches; (4) support epidemiologic studies for nanomaterial workers, including medical and exposure studies; and (5) assess and promote national adherence with risk management guidance. NIOSH requests public input to address the basis or rationale for priorities that NIOSH should give for studies of toxicity evaluation and/or workplace exposure characterization for engineered nanoparticles, and what rationale can be provided for recommending needs and types of technical and educational guidance materials. Comments are due March 19, 2013.
