Shutdown Turnaround Pre-Start Audit

Pre-start inspection for shutdown turnaround activities, focusing on blinds removal, energization, isolation tags, and operator readiness before equipment is returned to service.

Mechanical Completion and Area Readiness

• Work scope marked mechanically complete
  All planned turnaround work in the inspected area is complete and signed off by the responsible lead.
• Area free of tools, temporary materials, and debris
  No loose tools, scaffolding debris, rags, or temporary materials remain in the equipment or work area.
• Temporary covers, blanks, and maintenance barriers removed or controlled
  Temporary covers, maintenance barriers, and non-permanent restraints are removed unless specifically required for safe startup.
• Drain points, vents, and access openings secured
  Open drains, vents, manways, and access points are secured or restored to the required startup condition.
• Outstanding punch list items reviewed for startup impact
  Open punch list items have been reviewed and none create an unsafe condition for energization or operation.

Blinds, Isolations, and Energy Control

• Required blinds removed from the system
  All blinds scheduled for removal before startup have been removed and accounted for.
• Any remaining blinds are identified and approved to stay in place
  Any blinds left installed are documented, tagged, and approved by operations and engineering for the current operating condition.
• Isolation tags match the current isolation register
  Field tags, lockout devices, and the isolation register are aligned with the current status of the equipment.
• Lockout-tagout devices removed only after authorization
  LOTO devices have been removed only by authorized personnel after verification that the equipment is safe to energize.
• Energy sources verified in the correct startup state
  Electrical, pneumatic, hydraulic, steam, chemical, and mechanical energy sources are in the approved state for startup.
• Pressure relief, drain, and vent paths restored as required
  Relief devices, drains, vents, and related paths are restored to the required operating configuration.

Energization and Startup Readiness

• Pre-start checklist completed and signed off
  The approved pre-start checklist has been completed by the responsible parties.
• Interlocks, alarms, and trips tested or verified ready
  Required protective devices, alarms, and shutdown trips are tested, bypassed under control, or verified ready per procedure.
• Instrumentation and control systems restored to normal operating mode
  Control systems, transmitters, and associated instrumentation are restored from maintenance mode to the correct operating configuration.
• Utilities available within operating limits
  Required utilities such as power, instrument air, cooling water, nitrogen, or steam are available and within acceptable limits.
• Initial startup sequence reviewed with operations
  The startup sequence, hold points, and abnormal condition response have been reviewed with the operating team.
• Emergency shutdown and isolation controls accessible
  Emergency shutdown devices, isolation valves, and required access paths are accessible and unobstructed.

Operator and Crew Readiness

• Operator in charge identified
  A responsible operator or supervisor has been assigned to control the return-to-service process.
• Crew briefed on hazards and abnormal conditions
  The crew has been briefed on startup hazards, residual risks, and expected abnormal conditions.
• Required permits and authorizations in place
  All permits, approvals, and authorizations required for startup have been obtained.
• Communication method established for startup
  A clear communication method has been established between field, control room, and maintenance personnel.

Final Authorization and Handover

• All critical deficiencies closed
  No open critical deficiencies remain that would prevent safe return to service.
• Return-to-service authorization approved
  Operations and responsible authority have approved return of the equipment to service.
• Handover notes documented
  Any restrictions, temporary conditions, or follow-up actions are documented in the handover notes.
• Inspector signature
  Signature of the person completing the inspection.
