This book contains guidelines for clients who outsource manufacturing, brokers who aid in outsourcing, and manufacturers who develop and/or execute outsourced manufacturing on how to improve process safety performance by understanding and managing the risk associated with the process and learning from experience of outsourced operations. This book focuses on the outsourced manufacturing process and roles the affected parties assume. It applies the elements of risk based process safety to minimize the potential of process safety events. The book illustrates how the twenty Elements of the CCPS Risk Based Process Safety (RBPS) management approach can be used as the framework for a consistent, structured method to safely execute outsourced manufacturing. Additionally, ten case studies are provided detailing how breakdowns in the transfer of information in the various outsourced manufacturing process steps and failure for affected parties to understand their role in the process have led to process safety incidents.
