In this episode Terry Gorman, 3M’s Occupational Hygienist for the Personal Safety Division in Australia and New Zealand joins us to discuss welding fume … a known carcinogen.  In early 2017, welding fume was reclassified by the International Agency for Research on Cancer (IARC) from a classification of Group 2B, possibly carcinogenic to humans, to Group 1, Carcinogenic to humans. This change was mostly related to the effects of UV exposure on the skin and eyes, for lung cancers and limited evidence for kidney cancer, from welding fume exposures.
