Which types of records are typically reviewed to verify maintenance of safety-critical equipment?

• A. Maintenance logs, calibration records, and inspection checklists for safety-critical components.
• B. Personnel training records for general safety.
• C. Labor cost reports for maintenance personnel.
• D. Capital expenditure approvals for equipment.

Answer: (A)

Maintenance records are the primary evidence that safety-critical equipment is being cared for as required. Looking at maintenance logs shows what work was done, when it happened, who performed it, and what parts or components were replaced. Calibration records verify that instruments and sensors are kept within allowable tolerances, with documented calibration dates and results. Inspection checklists confirm that routine inspections were completed and any deficiencies were noted and addressed. Taken together, these records provide a clear, traceable history that the equipment receives regular maintenance and meets regulatory and manufacturer requirements.

Other types of records don’t directly prove ongoing maintenance of a specific safety-critical system. Training records indicate whether personnel are trained, not whether the equipment itself was maintained. Labor cost reports reflect expenses, not maintenance actions. Capital expenditure records show funding decisions, not the actual maintenance status of the equipment.
