Aerial Lift Pre Use Inspection
An aerial lift pre-use inspection is a documented, systematic check of an aerial lift's components, controls, safety devices, and work area, performed by the operator before each work shift and before using the lift. It verifies safe operating condition and compliance with regulatory and manufacturer requirements, including visual inspection, function tests, and verification of safety devices.
On a manufacturing or shop floor, the pre-use inspection is embedded into daily workflow as a mandatory, documented step before any aerial lift movement or elevation. The operator logs into a digital platform, selects the asset, and performs a work-zone assessment for overhead power lines, obstructions, and ground hazards. A 360° walk-around visual inspection checks structure, welds, pins, hydraulic system, electrical harnesses, tires, outriggers, guardrails, and safety decals. Fluid levels and power systems are checked. Control and safety device function tests are conducted at low elevation, including ground and platform controls, emergency stop, emergency lowering, tilt sensors, limit switches, and alarms. Deficiencies are documented, and safety-critical issues trigger lockout/tagout and maintenance work orders.
- Incomplete or purely 'checkbox' inspections where operators skip functional tests of emergency systems or only visually inspect, leading to unidentified failures of controls or interlocks.
- Ignoring structural and hydraulic defects such as cracked welds, bent guardrails, missing pins, and small hydraulic leaks, which can lead to catastrophic failure or uncontrolled lowering.
- Failure to inspect and control the work area, such as operating under overhead cranes or near energized bus bars without coordination, increasing risk of crush, collision, or electrocution.
What does OSHA specifically require for aerial lift pre-use inspections?
OSHA requires that prior to each work shift, a pre-start inspection be conducted to verify that the equipment and all components are in safe operating condition, following the manufacturer's recommendations. For construction, 29 CFR 1926.453(b)(2)(i) requires daily pre-shift inspections. The inspection must address vehicle components, lift controls, safety devices, and the work area, and any deficiencies must be corrected before operation.
How does WorkSafeBC treat aerial lift / MEWP pre-use inspections?
WorkSafeBC OHS Regulation requires that lifting equipment be inspected and all control and safety devices tested for each work shift before use. For MEWPs, operators must check the lift before every shift, looking for leaks, damaged tires, loose bolts/broken welds, missing safety pins or labels, faulty lights/alarms, and power issues, and must document the inspection and tag out the lift if any defects are found.
What is the technical threshold for removing an aerial lift from service during a pre-use inspection?
Any unsafe item that constitutes a safety hazard must be repaired or replaced before use, and the equipment must be taken out of service. Safety-critical conditions requiring immediate lockout/tagout include non-functional emergency stop or emergency lowering, hydraulic leaks from cylinders or major hoses, cracked or severely deformed structural components, missing guardrails, inoperative tilt alarms or limit switches, and steering or braking defects.
