In the mid-1990s, FMC was challenged with a corporate goal of manufacturing the safest and highest quality persulfate product for our global customers. Successfully meeting this challenge required a systematic multi-team approach utilizing both novel methods and standard tools in innovative ways to uncover the root causes of the accident. Novel and/or improved QC methods led to the creation of new product and process internal specifications, for routine QC laboratory monitoring of critical final product safety and quality specifications or parameters, and the quantification of a product parameter called "thermal stability," an excellent indicator of product and process safety, product and process quality, and reliability. The use of this parameter as a predicator of product stability in storage, shipping, and handling was validated and benchmarked by full-scale self-accelerating decomposition temperature tests. The FMC persufate process and operating conditions were subsequently modified based on lessons learned. As a result, the packaged persufate product has not undergone a decomposition in almost eight years. Addressing product safety automatically led to process safety improvements, and these, in turn, led to better product and process quality. Quality improvements meant better process reliability, increased capacity, reduced process downtime and operating costs, and improved customer satisfaction. Ultimately, this case study shows bow safety pays!.
