  1. Risk Management Panel Meeting March 12-14, 2019 Charleston, SC Approved for Distribution A

  2. IARC MONOGRAPHS ON THE EVALUATION OF CARCINOGENIC RISKS TO HUMANS Daniel O. Chute, CIH, CSPBSI EHS Services And Solutions East Inc. Reston, Virginia daniel.chute@bsigroup.com 703-689-9482 • WELDING, MOLYBDENUM TRIOXIDE, • AND INDIUM TIN OXIDE

  3. AIHA states in the September 2018 issue of The Synergist that “welding fumes cause lung cancer”..

  4. The Synergist based it’s conclusions on a 2018 Monograph produced by IARC. IARC – International Agency Research on Cancer –a specialized cancer agency of the World Health Organization. In March 2017, seventeen scientists from ten countries met at the International Agency for Research on Cancer in Lyon, France to evaluate the carcinogenicity of welding, molybdenum trioxide, and indium tin oxide. IARC review of literatures linked welding, molybdenum trioxide, and indium tin oxide to certain cancers.

  5. IARC Monograph process starts with a working group • 17 scientists from 10 countries • International Experts Selection of agents for review: • Agents are selected for review on the basis of two main criteria: • There is evidence of human exposure and • There is some evidence or suspicion of carcinogenicity.

  6. Population-based cohort studies on cancer and welding or exposure to welding fumes Page 113 – 145

  7. IARC Findings & Exposure limit values Page 64

  8. Exposure limit values - USA Welding Fumes Page 50; 272

  9. Questions for US Shipyard Welding • How does work described in IARC report compare to current welding process in US shipyard welding? • What potential cancer risks have been identified in the IARC report? • What welding work is most likely to create welding fume exposures at or above levels of concern? • What air monitoring and testing methods are recommended for further evaluation? • What existing training, process control and protective measures are shown to be effective for elimination or reduction of these potential hazards?
