Process Safety Management MOC Review Checklist [FREE PDF]

Management of Change (MOC) is a critical element of Process Safety Management (PSM) required under OSHA 29 CFR 1910.119(l) for facilities handling highly hazardous chemicals above threshold quantities. Failure to properly implement MOC procedures has been a root cause in numerous catastrophic process incidents, including explosions, toxic releases, and fires at chemical manufacturing facilities. This checklist guides Process Safety Engineers through a systematic MOC review ensuring that proposed

Industry: Chemical Manufacturing
Frequency: Per Event
Estimated Time: 60-120 minutes
Role: Process Safety Engineer
Total Items: 38
Compliance: OSHA 29 CFR 1910.119 - Process Safety Management of Highly Hazardous Chemicals, EPA 40 CFR Part 68 - Risk Management Program (RMP), EPA EPCRA Section 302 - Emergency Planning for Extremely Hazardous Substances, NFPA 30 - Flammable and Combustible Liquids Code, EPA 40 CFR 112 - Spill Prevention Control and Countermeasure (SPCC)

Change Description and Technical Basis

Document the full scope of the proposed change and verify the technical justification is complete.

Has the proposed change been formally documented with a clear written technical description and purpose?
Has the change been classified as a 'replacement in kind' or a true change requiring full MOC review?
Are the technical basis and engineering calculations supporting the change reviewed and signed by a qualified engineer?
Does the change documentation identify all affected process equipment, instrumentation, piping, and control systems?
Is the proposed implementation timeline documented with a defined start date and anticipated completion date?

Hazard Review and Process Hazard Analysis

Verify that a formal hazard review has been conducted for the proposed change consistent with PSM requirements.

Has a process hazard analysis (PHA) or what-if/HAZOP review been conducted specifically for this change?
Have new or modified hazard scenarios introduced by the change been identified and documented in the hazard review?
Have all hazard review recommendations been resolved, assigned, and tracked to closure before change implementation?
Has the impact on facility siting, occupied buildings, and evacuation routes been evaluated for the proposed change?
Has the impact on the facility's EPA RMP worst-case and alternative release scenarios been assessed?
Have consequences of the change for SPCC plan applicability or reportable quantity thresholds been evaluated?

Process Safety Information Updates

Confirm that all process safety information documents will be updated prior to or concurrent with change implementation.

Have all affected P&IDs (Piping and Instrumentation Diagrams) been identified for revision?
Have process flow diagrams, equipment specifications, and design codes/standards been identified for update?
Have updated SDS been obtained for any new or substitute chemicals introduced by the change?
Has a target completion date for all PSI document updates been established and assigned to a responsible party?
Will document control procedures ensure superseded versions of affected documents are archived and replaced?

Operating Procedure Review and Updates

Ensure all affected operating procedures are revised, approved, and available before startup of the modified process.

Have all affected operating procedures been identified and flagged for revision based on the scope of the change?
Have operating procedures for startup, normal operation, temporary operation, emergency shutdown, and startup after upset been reviewed?
Have revised operating procedures been approved by the appropriate technical authority before implementation?
Are safe operating limits (temperature, pressure, flow, composition) updated in procedures to reflect post-change conditions?
Are temporary procedures or interim modifications documented and time-limited with defined expiration or review dates?

Mechanical Integrity and Pre-Startup Safety Review

Assess the mechanical integrity requirements and pre-startup safety review (PSSR) readiness for the change.

Have affected equipment items been added to the facility's mechanical integrity program with appropriate inspection intervals?
Has new or modified equipment been verified to meet recognized and generally accepted good engineering practices (RAGAGEP)?
Has a Pre-Startup Safety Review (PSSR) been scheduled and is a PSSR team assigned prior to startup of the modified process?
Have process equipment pressure tests, leak checks, or functional tests been completed and documented?
Have safety instrumented system (SIS) or safety critical instrumentation changes been independently verified and function-tested?
What is the current operating temperature of the process unit being modified?

Employee Training and Communication Requirements

Verify that affected employees are trained on the change prior to startup and that communication is documented.

Have all affected operators and maintenance personnel been identified for change-specific training?
Has change-specific training content been developed covering new hazards, operating procedures, and emergency response?
Has documented training been completed and verified for all affected personnel before the change is placed in service?
Have contractor workers affected by the change been included in training and communication consistent with PSM contractor requirements?
Has the change been formally communicated to the Emergency Response team and local emergency responders if the hazard profile changes?

MOC Authorization, Approval, and Closeout

Confirm that the MOC has received all required approvals and that closeout conditions are formally documented.

Has the MOC received all required management approvals as defined in the facility's written MOC procedure?
Have all pre-implementation action items, hazard review recommendations, and PSSR findings been verified as closed?
Has the MOC package been archived in the facility's document management system with all supporting documentation?
For temporary changes, has a defined expiration date been set and a procedure established to return to the original design if not made permanent?
Has the MOC been reviewed for potential impact on the facility's Emergency Response Plan and local LEPC notification requirements?
Provide any additional notes, outstanding concerns, or follow-up items identified during this MOC review.
