Nanotechnology and Advanced Manufacturing“OS&H for 21st Century Manufacturing”WestON September 30, 2016Charles L. Geraci, Ph.D., CIHAssociate Director for NanotechnologyCenters for Disease Control and PreventionNational Institute for Occupational Safety and Health The findings and conclusions in this presentation have not been formally disseminated by the National Institute for Occupational Safety and Health and should not be construed to represent any agency determination or policy Overview• What is Nanotechnology? (Fast, I promise)• Why is it important to NIOSH and to you?• What has NOSH done?• Where have all the Nanomaterials gone?• What is Advanced Manufacturing and why is it a big deal? Nanotechnology: A Review Nanotechnology: 30 Second ReviewOld: Material behavior driven by chemistry and making things from big piecesNanoscale Science: making materials one molecule at a time at the nano scaleNew: Material behavior driven by size, shape, surface chemistry. More active and efficientResult: New material properties and behavior: Higher or newer hazard? Nanomaterial Science: Opening the 3rd Dimension of the Periodic Table ”Carbon just isn’t carbon anymore” Your Grandfather’s CarbonOld New The Nanomaterial designer’s carbon“Built” in the nm range Engineered Nanomaterials (ENMs)• Carbons– e.g., nanotubes, nanofibers, fullerene, graphene• Oxides– e.g., metal oxides, ceramics, TiO2, ZnO, SiO2, CeO2, Fe3O4• Metals– e.g., Ag, Fe, Al, Si, Zn, Cu, Ni• Cellulose– e.g., nano fibrils, nano crystals• Semiconductors– e.g., CdSe, CdS, InAs, InP• Polymers/organics– e.g., liposomes, dendrimers NIOSH Response: A Research Program – A blend of lab and fields projects – Nanotechnology Research Center (NTRC)• Established in 2004 to investigate new nanotechnology related hazards• One of the first agencies to identify that exposures to engineerednanomaterials (ENMs) could cause disease• Pioneered techniques to generate aerosols of engineerednanoparticles for animal testing• First to show that certified respirators and controls can protectworkers• Published practical guidance on measuring exposures and summaries of field results NIOSH Nanotechnology Research Center Active in Ten Critical AreasToxicology & Recommendations & GuidanceInternal DoseNTRCMeasurement Methods Informatics & ApplicationsGlobal CollaborationsFire & Explosion SafetyExposure AssessmentEpidemiology & SurveillanceRisk Assessment Controls & PPECentrally managed and coordinated for maximum impact Priority Goals for 2015- 20161. Increase understanding of new hazards and related health risks to nanomaterial workers and expand initial findings2. Expand field investigations and the creation of guidance on hazards, risks, and risk management approaches for workers, employers, agencies and policy makers.3. Support epidemiologic studies for nanomaterial workers including medical and exposure studies4. Assess and promote national and international adherence with risk management guidance.5.

Complicating the Task• Applications research is moving faster that EHS research. Keeping pace with a moving target.• No overt cases of injury or illness reported. Have we been good or lucky?• “Nano has gone stealth”. Its all now Advanced Materials• Reporting and tracking requirements are minimal. Likely• A precautionary approach, though warranted, is difficult to sell. See No. 2.to stay that way. Interface of Two Key National InitiativesNanotechnologyandAdvanced Manufacturing Why is this so important to learn about Advanced Manufacturing? Manufacturing: Still a Huge Economic Impact NIST MEP, 2015Average Mfg. wages 24% higherManufacturers contributed $2.17 trillion to the U.S. (NAM News) If U.S. Manufacturing were a separate country, 9th largest economyworldwide U.S. manufacturing fundamentals strong again: 900,000 direct jobs added since recession23 “Industry and Manufacturing in the Future” is not too far off.
