Management of Change 1. System Design
Management of change (MOC) A management system for ensuring that changes to processes are properly analyzed, documented, and communicated to affected personnel. Definitions
process chemicals, technology, equipment, procedures facilities Management of Change
Process Safety Information (l)(4) If a change covered by this paragraph results in a change in the process safety information required by paragraph (d) of this section, such information shall be updated accordingly.
Management of Change 1. Written MOC procedures 2. MOC owner 3. Defined scope 4. Defined roles and responsibilities System Design System Design
Management of Change 5. Management of Change log 6. Management of Change form 7. Periodic monitoring (field checks) 8. Auditing System Design
Change Originators DEFINING ROLES AND RESPONSIBILITIES
ROLES AND RESPONSIBILITIES Reviewers
MOC Coordinator ROLES AND RESPONSIBILITIES
ROLES AND RESPONSIBILITIES Employees
Senior Management ROLES AND RESPONSIBILITIES
Changes to cover under MOC 1. Capital improvement projects 2. Maintenance work orders 3. Instrument change requests 4. Spare parts control, warehousing, and distribution 5. Engineering change requests
Changes to cover under MOC 6. Research and development (R&D) process change recommendations 7. Company specifications 8. DCS programming change requests 9. Process experiments or tests conducted in the manufacturing plant. 10. Contractor service agreements
1. Keep it simple 2. Obtain acceptance 3. Field test the system 4. Provide adequate training Guiding Principles for Implementation
3. Maintaining an effective Management of Change (MOC) Process
1.Monitor effectiveness 2. Audit 3. Demonstrate commitment Maintaining an MOC System
Effectiveness of MOC System Key Performance Indicators 1.The number of MOCs performed each month. 2.The monthly percentage of work requests that are classified as a change. 3.The percentage of emergency MOCs. 4.The average backlog of MOCs. 5.The average calendar time from MOC origination to MOC authorization.
Effectiveness of MOC System Auditing 1.Documentation completed 2.Training conducted 3.Procedures reviewed for updating 4.Pre-Startup Safety Reviews
Management of Change Pre-Startup Safety Reviews
Pre-Startup Safety Review The term pre-startup safety review (PSSR) means a final check prior to initiating the use of process equipment.
PSSR It is applying a systematic method to confirm that the startup team and process equipment are prepared for startup.
Any change being made to an existing process, or any new facility being added to an existing process or facility, or any other activity a facility designates as needing a pre-startup safety review. Definitions Trigger Event
Non-change Trigger Event
When Should a PSSR be Performed 1.Capital project approved 2.Changes to Operating Facilities occur 3.Temporary Changes (Flixborough) 4.Restart of an idled process
1. Regularly evaluating industry process safety related incident reports and how PSSR was potentially involved in the situation. Best Practices – PSSR
2. Using electronic databases for capturing past PSSR documentation. Best Practices - PSSR
3. Performing PSSRs on selected critical maintenance activities. Best Practices - PSSR
4. Involving many different workers in the PSSR process. Best Practices - PSSR
5. Selecting a PSSR team leader who is somewhat removed from the specific project involving the change. Best Practices - PSSR
6. Showing open management support for the importance of PSSR. Best Practices - PSSR
Compiling and Using a PSSR Checklist
The role of the PSSR program is to provide a second layer of protection around the management of change element.
Compiling and Using a PSSR Checklist Depending upon the specific processes, materials, intermediates, and products involved, the PSSR checklist questions should be customized to match the facility.
