Insulated Aerial Device and Bucket Truck Dielectric Inspection

Inspection template for periodic dielectric testing and daily condition checks of insulated aerial devices and bucket trucks used for energized line work, with emphasis on insulation integrity, operating condition, and out-of-service criteria.

Inspection Setup and Unit Identification

• Inspection type selected
  Identify whether this is a daily condition inspection, periodic dielectric test, or both.
• Unit identifier recorded
  Record truck number, asset ID, or serial number.
• Inspection date and time
  Record when the inspection was completed.
• Inspector name and qualification
  Record the inspector and confirm they are a competent person or otherwise authorized to perform the inspection.
• Unit taken out of service before inspection if required
  Confirm the unit was not used if a critical defect was known before inspection began.

Daily Walk-Around Condition

• Boom, bucket, and structural members free of visible damage
  Check for dents, cracks, deformation, corrosion, or impact damage on the boom, bucket, and supporting structure.
• Insulating surfaces clean and dry
  Verify insulating components are free of dirt, grease, moisture, conductive contamination, and foreign material.
• Hydraulic lines, fittings, and cylinders free of leaks
  Inspect for hydraulic fluid leaks, damaged hoses, loose fittings, or seepage that could affect safe operation.
• Bucket liner, controls, and entry gate in good condition
  Verify the bucket liner is intact, controls are secure, and the entry gate/latch functions properly.
• Decals, warning labels, and load/rating placards legible
  Confirm required safety decals, operating instructions, and capacity markings are present and readable.

Operational Controls and Safety Devices

• Lower and upper controls operate smoothly
  Test all applicable lift, swing, boom, and bucket controls for proper response and no sticking or erratic movement.
• Emergency lowering or emergency stop functions operate correctly
  Verify emergency descent, stop, or override functions operate as designed.
• Outrigger, stabilizer, and interlock systems function properly
  Confirm stabilizers, outriggers, and associated interlocks engage and indicate correctly, if equipped.
• Platform/bucket leveling and rotation functions operate correctly
  Verify the bucket remains level and rotation or articulation functions respond normally, if equipped.
• Communication and radio/ground controls available if required by task
  Confirm required communication devices or ground controls are present and functional for the job plan.

Electrical Insulation and Dielectric Test Review

• Current dielectric test documentation available
  Confirm the unit has current dielectric test records available for review, including date and result.
• Dielectric test within required interval
  Verify the last dielectric test is within the required periodic interval established by the manufacturer, employer program, or applicable standard.
• Dielectric test result passed
  Confirm the most recent dielectric test passed without non-conformance.
• Insulating boom and bucket surfaces free of cracks, tracking, or punctures
  Inspect insulation surfaces for cracks, carbon tracking, punctures, delamination, or other visible defects.
• No unauthorized repairs or modifications to insulating components
  Confirm there are no field modifications, patched insulation, or repairs not approved by the manufacturer or competent authority.

Documentation, PPE, and Release to Service

• Required PPE available for energized line work
  Verify task-appropriate PPE is available and in serviceable condition, including electrical protective equipment as required by the job plan.
• Deficiencies documented with corrective action
  Record all deficiencies, non-conformances, and corrective actions, including out-of-service status when applicable.
• Unit released for service
  Confirm the unit is approved for use only if all critical items passed and no unresolved deficiencies remain.
• Inspector signature
  Inspector attests the inspection is complete and accurate.
