The American Institute of Chemical Engineers (AIChE) Center for Chemical Process Safety (CCPS) has developed a guideline describing a new risk based approach that an organization can use in defining and implementing a process safety management system specific to its unique needs. Recognizing the importance of safety culture as a determinant of safety performance, CCPS has included process safety culture as one element in the new risk-based process safety (RBPS) model. This paper will describe both the new process safety culture element and its integration in the overall ABPS model.
