Project Code: 31009
Review international legislation, guidance and best practice on control of Cr(VI) in the workplace.
Review and compile workplace exposure limits (WELs) or occupational exposure limits (OELs) for Cr(VI) worldwide.
Establish levels of Cr(VI) from a number of arc welding processes, to include MMA, TIG and MIG/MAG, over a range of parameters.
Assess the efficiency of local exhaust ventilation (LEV) and respiratory protection equipment in combination to meet a range of WELs for Cr(VI).
Provide clear guidance and evidence of the control measures required to meet current and proposed International limits for Cr(VI).
The project will demonstrate, by measurement, the effectiveness of different methods for control of exposure to Cr(VI) during arc welding, and identify where problems in meeting exposure limits may occur. As well as LEV and personal protective equipment, the use of fume extraction torches will be investigated. Guidance will be provided on the selection and use of appropriate control methods for each exposure scenario.
Relevant Industry Sectors

Technical and Economic Benefits
The work will enable users of arc welding to identify suitable approaches to comply with increasingly stringent regulations on exposure to Cr(VI).
