Nanomaterials: Best practices in nanomaterials risk prevention: awareness-raising and laboratory scenarios (CNRS, Paris – France)
Paris
Training
  • Training for nanomaterial handlers (technicians, engineers, PhD students, researchers, etc.) and prevention assistants
  • Organizers: CNRS
  • Objectives: learn about the risks involved in handling nanomaterials and the prevention and protection measures to be implemented, as well as best practices for limiting exposure.
  • Topics covered:
    • Health effects / Risk assessment
    • Preventive measures / Good laboratory practice / Time and space management / Collective and individual protection / Cleaning methods for surfaces, materials and equipment / Product storage / Product management
  • Hands-on workshops:
    • Implementing best practices when handling nanometric powders / Case studies / Assessment & recommendations
    • Case studies: risk analysis and recommendations
    • Examples of workstation design involving nanomaterials
