This session, chaired by Fabio Boccuni from INAIL, Italy, and co-chaired by Torunn Ervik from STAMI, Norway, brought together leading experts to discuss pivotal research and practical solutions PEROSH members have developed. Session Overview Title: From Dust to Nano Exposure Date: 13 June 2024 Chair: Fabio Boccuni, INAIL Co-Chair: Torunn Ervik, STAMI Speakers and Topics: Torunn Ervik and Pal Graff, STAMI: Title: Assessing Exposure to Carbon Nano Fibres and Carbon Nano Tubes in a Production Facility Abstract: This presentation explored methodologies for measuring exposure to carbon nanofibres (CNF) and carbon nanotubes (CNT) in a Norwegian production facility. The study revealed that while exposure levels often fell below the recommended threshold of 1 µg/m³ for respirable elemental carbon, risks remained, necessitating continued protective measures.
