Aerial Lift Pre-Operation Inspection Checklist: OSHA-Compliant Safety Guide
Aerial lifts—including boom lifts, scissor lifts, articulating boom platforms, and bucket trucks—pose significant safety risks when operated without proper inspection. OSHA statistics indicate that approximately 26 workers die each year in aerial lift incidents, with many more suffering serious injuries due to falls, tip-overs, structural failures, and contact with overhead hazards. A comprehensive pre-operation inspection represents the critical first line of defense against such incidents, allowing operators to identify potential hazards or mechanical issues before they result in catastrophic failures during elevated work.
The Essential Aerial Lift Pre-Operation Inspection Checklist

6. Fall Protection and Platform Safety
- Inspect platform floor for slippery conditions or debris
- Check lanyard attachment points for damage or wear
- Verify gate or entry chain closes and latches securely
- Inspect guardrails for secure attachment and proper height
- Check toe boards for security and condition
- Verify platform capacity placards are visible and legible
- Ensure platform extension locks function properly
- Check platform floor for holes, damage, or excessive wear
- Inspect personal fall protection equipment (harnesses, lanyards)
- Verify presence of appropriate PPE for the planned work
Step-by-Step Aerial Lift Inspection Procedure
Initial Preparation
Begin by reviewing the operator's manual, previous inspection reports, and maintenance records. Verify your training and authorization to operate the specific model of aerial lift. Ensure you're familiar with all controls and emergency procedures.
Evaluate the work area for hazards, particularly overhead power lines, obstructions, unstable ground, and potential traffic. Establish a safe perimeter with appropriate barriers or warning cones to prevent unauthorized entry into the work zone.
Ground-Level Inspection
Perform a 360° walkaround inspection, examining the chassis, base, outriggers, tires, and lower structural components. Look for damage, leaks, loose fasteners, or signs of structural issues. Check that all safety decals are present and legible.
Check all fluid levels including hydraulic oil, engine oil (if applicable), fuel, and coolant. Inspect hydraulic components for leaks, damaged hoses, or loose connections. Verify batteries are adequately charged and connections are secure for electric lifts.
Inspect outriggers and stabilizers for damage or defects. Verify pins, locks, and pads are in good condition. For units with hydraulic outriggers, check for leaks or damage to cylinders and hoses.
Control Testing
With the aerial lift powered on, test all ground control functions including lift, lower, extension, rotation, and emergency systems. Verify smooth operation with no unusual noises, jerking, or hesitation. Test the emergency stop and ensure it immediately halts all functions.
Enter the platform following proper access procedures. Test all platform controls through their full range of motion, verifying smooth and responsive operation. Check that the control panel is undamaged with all labels visible. Test the emergency stop button at the platform position.
Test all safety devices including tilt sensors, motion alarms, limit switches, and load management systems. Verify the emergency lowering function operates correctly from both control stations. Check communication systems between ground and platform.
Platform Inspection
Inspect the platform floor, guardrails, entry gate/chain, and attachment points. Verify all components are secure with no cracks, deformation, or excessive wear. Check that the platform is clean and free of trip hazards or slippery substances.
Inspect lanyard attachment points for damage or wear. Check personal fall protection equipment including harnesses and lanyards for cuts, fraying, or other damage. Verify that fall protection is adequate for the planned work activities.
Perform a final function test of all systems with the platform at low elevation. Verify proper operation of all movement functions, brakes, and steering. Listen for unusual noises and feel for abnormal vibrations that might indicate developing issues.
Documentation and Reporting
Complete all required inspection documentation, noting any issues found during the inspection process. Categorize deficiencies based on severity, with safety-critical items clearly identified for immediate attention.
Report any deficiencies according to your company's procedures. If safety-critical issues are identified, tag the equipment as "Out of Service" and ensure it is not used until properly repaired by qualified personnel.
| Aerial Lift Type | Special Inspection Considerations |
|---|---|
| Articulating Boom Lifts | Pay special attention to all pivot points, knuckle joints, and extension cylinders |
| Telescoping Boom Lifts | Carefully inspect extension mechanisms, wear pads, and extension chains/cables |
| Scissor Lifts | Focus on scissor stack components, cross-bracing, and pothole protection systems |
| Bucket Trucks | Inspect insulation components for damage (especially for units rated for electrical work) |
| Vertical Mast Lifts | Check mast sections, rollers, and sequencing cables for proper condition |
Conclusion
Thorough pre-operation inspections of aerial lifts are not merely regulatory requirements—they are critical safety procedures that protect workers from potentially fatal hazards. By systematically examining each component and system before operation, operators can identify developing issues before they result in catastrophic failures at height, where the consequences are most severe.
Transform Your Aerial Lift Safety Program with HVI
While traditional paper inspection forms have long been the industry standard, forward-thinking companies are now embracing digital solutions like the HVI App (Heavy Vehicle Inspection and Maintenance software) to enhance their aerial lift safety programs. This powerful platform revolutionizes aerial lift inspections in several important ways:
- Model-Specific Inspection Protocols: HVI provides customized inspection checklists for each specific make and model of aerial lift in your fleet, ensuring all manufacturer-recommended inspection points are systematically covered.
