Operational Readiness Review (ORR) Checklist and Process

Author: Fidelis Associates | Published: 2026-03-02 | Last Updated: 2026-03-02

Meta Description: A comprehensive Operational Readiness Review (ORR) checklist covering procedures, training, safety systems, permits, and stakeholder alignment for industrial facility startups.

---

Definition / Introduction

An Operational Readiness Review (ORR) is the structured assessment that confirms a facility, its people, and its management systems are ready for safe startup and sustained operations. Unlike the PSSR, which satisfies a specific OSHA regulatory requirement, the ORR is a broader evaluation that addresses organizational, procedural, and systemic readiness across every function involved in operations.

This checklist is designed for commissioning managers, startup leads, operations directors, and HSE professionals responsible for verifying readiness before introducing process fluids or transitioning from project to operations. Each section covers a distinct readiness category with verification items drawn from industry best practices and field experience across greenfield facilities, major turnarounds, and brownfield modifications.

Procedures and Documentation

• [ ] Operating procedures are written, reviewed, and approved for all operating phases: startup, normal operations, shutdown, emergency shutdown, and emergency operations
• [ ] Procedures are accessible in the control room and in the field where they will be used
• [ ] Maintenance procedures are in place for all critical equipment and safety-instrumented systems
• [ ] Emergency procedures address credible scenarios identified in the process hazard analysis
• [ ] Procedures have been field-validated by walking through steps at the actual equipment with operators
• [ ] All as-built documentation (P&IDs, wiring diagrams, equipment data sheets) is complete and reflects installed conditions
• [ ] Turnover packages are complete for all systems, including test records, punch lists, and completion certificates

Personnel and Training

• [ ] The operations team is fully staffed with qualified personnel for all shifts
• [ ] Shift schedules are published and cover the startup period, including extended or overlapping shifts if needed
• [ ] All operators have completed initial training on process overview, operating procedures, safety hazards, and emergency operations
• [ ] Training includes hands-on competency verification, not just classroom attendance
• [ ] Maintenance personnel are trained on equipment-specific procedures and safety system maintenance
• [ ] Roles and responsibilities are documented and communicated for the startup period — including escalation paths for abnormal conditions
• [ ] Experienced startup or commissioning specialists are available on-site during initial startup

Safety Systems

• [ ] All safety instrumented systems (SIS) have been tested and are functional, with test records documented
• [ ] Emergency shutdown (ESD) systems have been tested end-to-end, including cause-and-effect verification
• [ ] Fire and gas detection systems are commissioned, calibrated, and integrated with alarm and shutdown systems
• [ ] Pressure relief devices are installed, set correctly, and documented with relief valve data sheets
• [ ] Fire protection systems (deluge, sprinklers, monitors, foam systems) are tested and operational
• [ ] Safety critical instrument overrides and bypasses are tracked, with clear criteria for when they must be removed before startup
• [ ] All safety system test records are filed and accessible for audit

Utilities and Support Systems

• [ ] Instrument air system is tested, dried, and delivering air at the required pressure and quality
• [ ] Cooling water, steam, and other process utilities are available and verified at each user point
• [ ] Electrical systems are energized, load-tested, and emergency power (generators, UPS) has been verified
• [ ] Nitrogen supply is available for inerting and purging operations during startup
• [ ] HVAC systems for control rooms, substations, analyzer shelters, and enclosed areas are operational
• [ ] Waste management systems (flare, drain, wastewater treatment) are ready to receive material during startup
• [ ] Communication systems (radios, public address, emergency notification) are tested and operational on all channels

Permits and Regulatory Compliance

• [ ] All required operating permits (air, water, waste) are issued and conditions understood by operations
• [ ] Environmental monitoring systems are installed, calibrated, and operational
• [ ] Regulatory notifications have been completed as required (OSHA, EPA, state agencies, local fire marshal)
• [ ] PSSR requirements under OSHA 1910.119 are satisfied or scheduled with documented completion plan
• [ ] Local fire department and emergency responders have been notified of the startup schedule
• [ ] Any permits-to-operate from the Authority Having Jurisdiction (AHJ) have been obtained
• [ ] Insurance requirements and notifications have been met

Stakeholder Alignment

• [ ] Operations, engineering, maintenance, and HSE leadership have formally confirmed readiness in their areas of responsibility
• [ ] The startup plan has been reviewed and approved by all key stakeholders, including facility management and corporate oversight if applicable
• [ ] Roles are clearly defined: who has authority to stop startup, who authorizes introduction of hazardous materials, who makes final go/no-go decisions
• [ ] Vendor and licensor startup support personnel are confirmed and mobilized
• [ ] EPC contractor demobilization plan is aligned with the operations team's readiness to assume system ownership
• [ ] Open risk items from the ORR are documented with owners, mitigations, and acceptance criteria

Communication Systems

• [ ] Radio channels are assigned for operations, maintenance, safety, and emergency communications
• [ ] Radio coverage has been tested in all areas of the facility, including remote and enclosed spaces
• [ ] Public address system reaches all occupied areas and assembly points
• [ ] Emergency notification system (alarm, siren, PA announcement) has been tested with all personnel
• [ ] Communication protocols for critical startup steps are documented — who communicates what, to whom, and when
• [ ] Backup communication methods are identified and tested in case primary systems fail

Maintenance Readiness

• [ ] Computerized maintenance management system (CMMS) is populated with equipment data, PM schedules, and spare parts inventory
• [ ] Critical spare parts are on-site and accessible, with a documented minimum stock list
• [ ] Predictive maintenance baseline data (vibration, thermography, oil analysis) has been collected where applicable
• [ ] Maintenance workshop, tools, and consumables are available for first-run support
• [ ] Vendor support contacts and escalation procedures are documented for all major equipment

Punch List and Open Items

• [ ] Category A (safety-critical) punch list items are closed with documented evidence
• [ ] Category B items that remain open have documented risk assessments and target closure dates
• [ ] A punch list review cadence is established for the startup period (daily or weekly)
• [ ] Escalation process is defined for overdue or disputed punch list items
• [ ] No punch list items have been reclassified from Category A to Category B without formal risk assessment and approval

Key Takeaways

• ORR is broader than PSSR — it evaluates the entire organization's readiness to operate, not just regulatory compliance for the introduction of hazardous chemicals.
• The most common ORR failures are procedures that have not been field-validated, training that verifies attendance but not competency, and safety system punch items that are misclassified as non-critical.
• ORR should include both internal and external reviewers to reduce the risk of rationalized gaps.
• Formal stakeholder sign-off with clear go/no-go authority is essential to prevent schedule pressure from overriding safety readiness.
• ORR findings must be tracked to closure with the same rigor as PSSR findings.
