Boiler Annual External and Internal Inspection

Annual inspection template for heating boilers covering external and internal condition, certificate posting, and documented findings for ASME Section VI and applicable state jurisdictional requirements.

Inspection Scope and Boiler Identification

• Boiler identification recorded
  Record boiler tag number, manufacturer, model, serial number, capacity, and location.
• Inspection date and inspector credentials recorded
  Document the inspection date, inspector name, and license or authorization details as required by the AHJ.
• Boiler type and service verified
  Confirm the boiler type and service category for the record.
• Inspection scope includes external and internal examination
  Verify that both external and internal inspection activities are included in this annual review.
• Applicable jurisdiction and code basis documented
  Record the state jurisdiction, ASME Section VI reference, and any applicable local boiler rules used for the inspection.

Certificate Posting and Compliance Records

• Current boiler inspection certificate posted or available
  Confirm the current annual inspection certificate is posted at the boiler or maintained where required by the AHJ.
• Certificate matches boiler identification
  Verify the certificate or record matches the boiler location, serial number, and jurisdiction.
• Certificate issue and expiration dates recorded
  Record the issue date, expiration date, and inspection cycle applicable to this boiler.
• Prior deficiencies and corrective actions reviewed
  Confirm previous inspection findings were reviewed and closed or tracked to completion.
• Required records available for AHJ review
  Verify maintenance logs, repair records, and prior inspection reports are available for review.

External Condition and Operating Controls

• No active leaks, visible corrosion, or abnormal staining
  Inspect the boiler exterior, piping, fittings, and nearby surfaces for leaks, corrosion, or evidence of water discharge.
• Pressure/temperature gauges readable and within normal operating range
  Verify gauges are legible, properly mounted, and indicate normal operating conditions.
• Low-water cutoff, pressure controls, and operating controls present and intact
  Confirm required operating and safety controls are installed, accessible, and show no visible damage.
• Safety relief valve discharge piping and termination acceptable
  Verify discharge piping is properly routed, unobstructed, and terminates in a safe location.
• Burner, ignition, and fuel train area free of obvious defects
  Check for damaged components, loose connections, soot accumulation, or signs of improper combustion.
• Housekeeping and access around boiler adequate
  Verify the boiler room is accessible, free of combustible storage in unsafe proximity, and allows safe inspection and maintenance access.

Internal Condition and Water-Side Examination

• Boiler safely shut down, isolated, and opened for internal inspection
  Confirm lockout-tagout, isolation, depressurization, and safe access were completed before internal examination.
• Internal surfaces free of heavy scale, sludge, or pitting
  Inspect waterside surfaces for scale buildup, sludge, pitting, or other deterioration affecting safe operation.
• No evidence of cracking, bulging, distortion, or overheating
  Check pressure parts, tubes, drums, and accessible internal surfaces for structural distress or heat damage.
• Water-side corrosion condition documented
  Rate the overall internal corrosion condition observed during inspection.
• Manway, handhole, and gasket surfaces acceptable
  Verify openings, covers, and gasket surfaces are serviceable and free of damage that would prevent proper reassembly.
• Internal inspection findings documented
  Record all internal observations, including deposits, repairs needed, and any areas requiring follow-up.

Safety Devices, Testing, and Corrective Actions

• Safety relief valve condition acceptable
  Confirm the relief valve shows no leakage, corrosion, tampering, or signs of improper installation.
• Required safety device tests performed or witnessed
  Record whether applicable safety device tests were performed, witnessed, or verified per site procedure and jurisdictional requirements.
• Deficiencies and non-conformances documented
  List all deficiencies, non-conformances, and critical items requiring repair, retest, or AHJ notification.
• Corrective action owner and due date assigned
  Identify the responsible person or contractor and the target completion date for each corrective action.
