Key challenges

Hexavalent chromium

During the production process for ferrochrome, very low concentrations of hexavalent chromium, a known carcinogen, may be produced under certain conditions. Xstrata Alloys is engaged in research to improve the accuracy of sampling for this unstable compound and together with a range of scientific and academic experts has developed a standard for sampling and analysis at our operations. Xstrata Alloys conducts health risk assessments to manage this issue. Employees are divided into homogenous exposure groups and action plans are developed based on exposure and monitoring requirements. Non-invasive biological monitoring for hexavalent chromium is undertaken for all exposed employees.

All chrome operations have air quality management programmes that include fume extraction hoods for all furnaces, comprehensive sampling and analysis of all waste streams including ambient air and water and biological monitoring for hexavalent chrome. Managers have been appointed to drive these programmes, which are reviewed regularly by senior management.
