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.

Training
  • E-learning program: awareness-raising for personnel who come into contact with nanomaterials during research, formulation, production, maintenance, cleaning, upkeep, etc., as well as safety coordinators or engineers, facility managers, heads of laboratories where nanoparticles are handled.
  • Organizers: INSTN Grenoble (CEA)
  • On the program:
    • 1 – Introduction, definition and characteristics of nanomaterials
    • 2 – Toxicity of nanomaterials: the state of knowledge
    • 3 – Metrology and characterization of nanomaterials
    • 4 – Prevention and protection against nanomaterials in the workplace
    • 5 – Quiz: assessment of learning outcomes
  • The 2-hour course can be viewed for one month from the date of registration.
