The presence of carcinogenic hexavalent chromium in the combustion deposits on the gas turbines in the LNG industry has recently gathered a lot of attention as it relates to potential exposure to maintenance workers when performing routine engine change outs and servicing. This presentation is a case study of how the issue was first identified in our onsite turbines during routine servicing, the immediate response, sampling methods used to identify Cr(VI) as well as the controls put in place to manage exposure.
