The highly toxic SF6 decomposition product S2F10 is suspected to constitute a health risk associated with gas insulated equipment. In this paper a method is presented by which maximal S2F10 concentrations in operating GIS can be estimated under worst case conditions. The method is based on simple integral discharge models and makes use of the results of the CRADA activity. It is found that neither partial discharge activity nor disconnector switching can lead to risk relevant S2F10 concentrations.
