In September 2011 Solvay took control of the Rhodia group of companies and became the 10th largest chemical group in the world. Now the approaches used to carry out risk analysis and ensure safe operation of chemical plants were quite different in Solvay and Rhodia. Following the fusion Solvay has decided to introduce new and harmonized methods to control process risks. The methods adopted draw on elements from both cultures. In this article the methods used previously within Solvay and Rhodia are outlined. The methods adopted under the new Solvay are described with respect to: Process Safety Management, System Feedback from process incidents within Solvay, Process Safety Design Guidelines, Process Risk Analysis, Process Safety Roadmap.
