covid-19 masks biocide regulation

In a notice to operators, the DGCCRF and ANSM recalled some essential points to be considered before marketing surgical masks. In particular, the risks related to the presence of a biocidal substance or material must be assessed and that this assessment must take into account, among others, the particular risk of exposure to nanoparticles.

If the mask incorporates a nanomaterial, it will fall under Class IIa, IIb, or III with respect to internal exposure potential under Regulation (EU) 2017/745 on medical devices and this will therefore require the involvement of a notified body.

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
