Air Vacuum Excavation Pre-Operation Check

Pre-operation inspection template for air-based vacuum excavation units, covering compressor condition, debris tank integrity, vacuum boom operation, hose condition, nozzle integrity, and safety controls before use.

Inspection Details and Equipment Identification

• Equipment ID, unit number, and location recorded
  Record the vacuum excavator identifier, asset number, and current jobsite or yard location.
• Inspector confirms pre-operation check completed before startup
  Verify the inspection is performed before the unit is placed into service.
• Operator manual and required inspection form available
  Confirm the equipment-specific operating instructions and inspection record are available at the point of use.

Compressor and Air Supply System

• Compressor housing, guards, and mounting hardware secure
  Inspect for loose fasteners, damaged guards, cracked mounts, or missing covers.
• Compressor oil, coolant, and fluid levels within operating range
  Verify fluid levels are within the manufacturer-specified range and there are no visible leaks.
• Belts, hoses, and air lines free of cracks, abrasion, and leaks
  Check all visible compressor-related hoses and lines for wear, chafing, bulging, or air leakage.
• Pressure gauges and relief devices present and legible
  Confirm gauges are readable and relief devices are installed, undamaged, and not bypassed.

Debris Tank and Vacuum Vessel

• Debris tank shell, seams, and welds free of visible damage
  Inspect the tank body for dents, deformation, corrosion, cracks, or signs of structural compromise.
• Tank doors, latches, clamps, and seals secure and intact
  Verify closures operate properly and seals, gaskets, and O-rings are present and undamaged.
• Vacuum relief, venting, and level indicators functional
  Confirm venting components are unobstructed and level indicators are visible and operating as intended.
• Debris tank is empty or within safe fill limit for operation
  Record the estimated fill level as a percentage of tank capacity.

Vacuum Boom, Hose, and Nozzle Condition

• Vacuum boom pivots, locks, and supports operate smoothly
  Inspect boom movement, locking points, and support hardware for binding, excessive play, or damage.
• Vacuum hose free of cuts, punctures, soft spots, and severe wear
  Inspect the full visible hose length for abrasion, kinks, bulges, delamination, or exposed reinforcement.
• Hose couplings, clamps, gaskets, and O-rings intact and tight
  Verify all fittings are properly seated, secured, and free of air leaks or missing sealing components.
• Nozzle, wand, and end fittings free of damage or blockage
  Check the nozzle and related end fittings for cracks, deformation, clogging, or loose attachment.
• Vacuum hose routing prevents pinch points and contact with hot or moving parts
  Confirm hose routing avoids sharp edges, rotating components, exhaust heat, and trip hazards.

Controls, Safety Devices, and Work Area Readiness

• Emergency stop and shutdown controls function properly
  Test accessible emergency stop and shutdown controls before operation.
• Warning labels, operating placards, and hazard markings legible
  Confirm required labels are present and readable from normal operating positions.
• PPE selected for the task is available and in use
  Select the PPE verified for this operation.
• Work area clear of bystanders and overhead/underground hazards identified
  Verify the work zone is controlled and the competent person has identified known utility and site hazards before use.

Defects, Non-Conformances, and Release to Service

• Defects or non-conformances documented and reported
  Record any deficiency found during inspection and notify supervision or maintenance as required.
• Equipment released for operation
  Confirm the unit is safe to place into service after inspection.
• Inspector signature
  Inspector signs to confirm the pre-operation check is complete and accurate.
