Abstract
Process Safety Management (PSM) is a management system that is focused on prevention of, preparedness for, mitigation of, response to, and restoration from catastrophic releases of chemicals or energy from a process plant. OSHA/PSM guidelines indicate the 14-elements as it is a performance-oriented standard. In Japan, the importance of PSM based on plant lifecycle engineering, which is from research and development to plant safety design, construction, production and consistent maintenance stages, has been also recognized in chemical processes for several years. This paper focuses on plant maintenance functions for PSM. Purpose of PSM activity at plant maintenance stage is to maintain integrity of functions of facility and plant simultaneously with production. For the 14-elements of OSHA/PSM, activities of plant maintenance for PSM are clarified and typical tasks of it are listed.
