IOHA 2018: 8th International Control Banding Workshop, 24-26 September 2018, Washington DC

Henri Heussen (Cosanta) and Dave Zalk (Lawrence Livermore National Laboratory) organised this 4-session workshop on behalf of the IOHA Board. It aims to discuss the complete picture of success and failure factors of CB and beyond….strategies. Please listen to our presentation “Stoffenmanager®: Do companies require more than a validated exposure model?” in session 2. Furthermore, you are of course most welcome to share your experiences in all sessions!

Session 1 – History, Implementation and Future of Control Banding

Session 2 – Evaluation of REACH Tier I & 1.5 Tools – The Eteam Study: Follow up by Tool Owners

Session 3 – Hazard Banding/Occupational Exposure Banding

Session 4 – Evaluation of Quantitative Exposure Models

Control Banding (CB) strategies to prevent work-related illness and injury for 2.5 billion workers without access to health and safety professionals have grown exponentially during the last 20 years. CB applications have broadened into chemicals in general - including new emerging risks like nanomaterials and also into ergonomics and injury prevention. Originally CB was an action-oriented qualitative risk assessment strategy offering solutions and control measures to users through “toolkits”. But over the last decade CB has gone beyond its traditional qualitative approach meaning that some chemical CB tools like Stoffenmanager® and EMKG-Expo-Tool additionally offer quantitative assessments. Other chemical quantitative exposure assessments tools like ART, ECETOC TRA and MEASE have become available too. Furthermore, user needs have become more demanding meaning that tools should not only focus on CB itself, but additionally should provide a complete chemicals management platform.

To be accepted by authorities and other stakeholders such as the occupational hygiene community, underpinning of the underlying exposure models with sound data has become increasingly important. At the previous 7th CB conference the results of the Eteam study on the validation of lower tier exposure tools used for REACH were presented. Since then, several new studies, also on higher tier exposure tools, have been published or are underway. But it was not only the exposure element of the tools that was studied. Due to increasing pressure on substitution of CMR(S) chemicals, the validation of different hazard or occupational exposure banding schemes was questioned and the first studies have appeared.

Last but not least, it has been shown that just “offering” a control banding tool, without providing active support, does not automatically result in its use by SMEs, and even less in its “proper” use. For successful implementation of CB and beyond…. strategies, aspects other than technical reliability model issues need to be covered as well.
