Arc Flash Hazard Study Field Verification Inspection

Field verification inspection to confirm arc flash labels installed on electrical equipment match the current incident energy analysis, are legible, date-stamped, and include required PPE and hazard information.

Inspection Scope and Equipment Identification

• Equipment ID matches field location and one-line documentation
  Verify the equipment nameplate, asset ID, and physical location match the inspection record and available electrical documentation.
• Equipment is within the scope of arc flash labeling requirements
  Confirm the equipment is energized or capable of being energized and is the type covered by the current arc flash study and labeling program.
• Inspection date and inspector recorded
  Record the date, time, and inspector name for traceability.
• Equipment type
  Select the primary equipment type being inspected.

Label Presence, Placement, and Legibility

• Arc flash label is present on the equipment
  Verify a current arc flash label is installed on the equipment in a visible location.
• Label is legible and not obscured
  Confirm the label can be read without obstruction, fading, peeling, damage, or contamination.
• Label is securely affixed and appropriately located
  Verify the label is attached to the correct equipment surface and positioned where it is readily visible to qualified persons before exposure.
• Label condition
  Assess the physical condition of the label.

Current Incident Energy Analysis Match

• Label incident energy matches current study
  Compare the label's incident energy value to the latest approved incident energy analysis for the equipment.
• Label arc flash boundary matches current study
  Verify the arc flash boundary shown on the label matches the current study or approved engineering basis.
• Label PPE category or required PPE matches current study
  Confirm the PPE information on the label matches the current incident energy analysis and site PPE guidance.
• Label data fields match study values
  Verify voltage, arc flash boundary, incident energy, working distance, and other posted values are consistent with the current study.
• Any mismatch identified between label and study
  Document any deviation between the installed label and the current incident energy analysis.

Label Date, Revision Control, and Documentation

• Label includes a date stamp or revision identifier
  Verify the label includes a date stamp, revision date, or other traceable identifier tied to the current study.
• Label revision is current and approved
  Confirm the label revision corresponds to the latest approved arc flash study or authorized update.
• Supporting documentation available at site
  Verify the current arc flash study, one-line diagram, or label register is available for review or accessible through site records.
• Documentation gap or record control issue
  Describe any missing, outdated, or uncontrolled documentation affecting label verification.

Deficiencies, Corrective Actions, and Closeout

• Deficiencies recorded and assigned
  Record each non-conformance, assign the responsible party, and note the required corrective action and due date.
• Immediate hazard controls implemented where needed
  Confirm interim controls are in place for any critical mismatch, missing label, or unreadable label until corrected.
• Inspector signature
  Signature confirming the field verification is complete and the findings are accurate.
