Provides guidance on the implementation of effective and efficient Management of Change (MOC) procedures, which can be applied to improve process safety. In addition to introducing MOC systems, the book describes how to design an initial system from scratch, including the scope of the system and the applications over a plant life cycle and the boundaries and overlaps with other process safety management systems. MOC is a process for evaluating and controlling adjustments to facility design, operations, organization, or activities--prior to implementation--to make certain that no new hazards are introduced and that the risk of existing hazards to employees, the public, or the environment is not unknowingly increased. It includes case studies and real-life examples plus CD-based support tools, and details the methods for measuring, auditing, and improving the efficiency and effectiveness of process safety.
