Titanium dioxide nanoparticles: exposure limits to avoid occupational cancers

.
.
.

With 17,000 tons produced or imported each year in France (according to industry declarations), titanium dioxide in nanoparticulate form is one of the most widely used nanomaterials in various industrial sectors: paints, glass, cosmetics, plastics, textiles, etc.

Many workers are therefore exposed to it, with a risk of pulmonary inflammation that can lead to the development of cancers.

The French National Agency for Health Safety (Anses) publishes today its recommendations for occupational exposure limit values (OELV ) to reinforce risk prevention for workers exposed to TiO2 nanoparticles by inhalation: OELV-8h of 0.80 µg/m3 and an estimated STELV-15 min of 4 µg/m3.

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
