  1. Start Basic Characterization Exposure Assessment Unacceptable Acceptable Uncertain Control Measures Further Information Gathering Periodic Re-Assessment A Strategy for Assessing and Managing Occupational Exposures

  2. How do we develop the comprehensive metrology, instrumentation, and standards to support a nanotechnology ESH program?

  3. Control Approach • General Ventilation • Engineering Control • Containment • Specialist Advice Exposure ManagementControl banding - concept Parameters Amount Used Dustiness Hazard Group (R-Phrase) www.ilo.org NIOSH: TJ Lentz

  4. A requirement from the U.K. Regulationson Control of Substances Hazardous to Health (COSHH) COSHH requires you to carry out health surveillance in the following circumstances: • where employees are exposed to a substance linked to a particular disease or adverse health effect • and there is a reasonable likelihood, under the conditions of the work, of that disease or effect occurring • and it is possible to detect the disease or health effect. Reference: COSHH: A brief guide to the Regulations What you need to know about the Control of Substances Hazardous to Health Regulations 2002 (COSHH), Health and safety Executive, INDG136rev3 04/05 C2000 (April 2005).

  17. Approaches to Safe Nanotechnology is a dynamic document about which NIOSH seeks public input, and that NIOSH will periodically update. • Developing a comprehensive, centralized information management system across agencies and organizations would be a significant contribution www.cdc.gov/niosh/topics/nanotech
