A complete, OSHA-grounded aerial lift inspection checklist starts with testing controls daily and physically verifying every safety system before the shift begins.
Does OSHA require a daily aerial lift inspection before every shift?
Yes. 29 CFR 1926.453(b)(2)(i) requires that lift controls be tested each day prior to use to determine that such controls are in safe working condition. You must complete this test before operation begins on each shift. The identical requirement appears at 29 CFR 1910.67(c)(2)(i) for general industry. OSHA’s regulation text does not list every component you must check. The broader multi-component checklist comes from the manufacturer’s instructions and the ANSI/ASSP A92 consensus standards. Your employer must ensure you have access to and understand those manufacturer instructions for the specific model on-site. Treat the daily control test as the floor, not the ceiling. If you find a deficiency during the test, tag the machine out and notify your supervisor. Operation begins only after the deficiency is corrected.
What must a competent person check during the physical walk-around?
Start with the data plate. It must be legible and intact. It lists the maximum platform capacity in pounds or kilograms, the manufacturer name, model designation, serial number, and year of manufacture. The capacity figure includes the weight of all personnel, tools, materials, and equipment on the platform. Neither 29 CFR 1926.453 nor 29 CFR 1910.67 imposes a nameplate or data-plate legibility requirement. A defaced, painted-over, or missing capacity plate is not in itself an OSHA violation of those sections. However, OSHA compliance officers are increasingly enforcing violations related to illegible decals and load charts. The manufacturer instructions and the ANSI/ASSP A92 consensus standards require legible plates. If the plate is unreadable or gone, take the machine out of service until the nameplate is restored to legibility under the manufacturer’s instructions.
Check the hydraulic system for leaks. The pre-use inspection must verify that hydraulic systems are free of leaks, including small weeping leaks that may indicate seal degradation. A pinhole leak or weeping cylinder is a precursor to catastrophic pressure loss and a potential platform drop, particularly in high-reach scenarios. Use cardboard to detect small leaks. Never place your hands near suspected high-pressure areas because of the risk of high-pressure injection injury.
Inspect the guardrails for damage, missing pins, or improper height. Guardrail systems on MEWPs must comply with 29 CFR 1926.502(b). The top rail must be 42 inches plus or minus 3 inches above the walking or working level. Midrails must be installed approximately halfway between the top edge and the walking or working level. The top rail must be capable of withstanding a force of at least 200 pounds applied within 2 inches of the top edge in any outward or downward direction.
Inspect your fall protection components and their anchor points before you ascend. For boom-supported aerial lifts, 29 CFR 1926.453(b)(2)(v) requires that a personal fall protection system be worn and attached to the boom or basket. Full-body harnesses are required. Body belts are prohibited as part of a personal fall arrest system as of January 1, 1998 under 29 CFR 1926.502(d). Check the harness and lanyard for UV damage, chemical splashes, frayed stitching, or worn hardware. MEWP operators often work near welding or painting that degrades synthetic webbing faster than in other trades.
Anchorage points used for personal fall arrest equipment must be capable of supporting at least 5,000 pounds per employee attached, or be designed, installed, and used under the supervision of a qualified person as part of a complete personal fall arrest system that maintains a safety factor of at least two. That requirement is found at 29 CFR 1926.502(d)(15). The attachment point of the harness must be located in the center of the wearer’s back near shoulder level or above the wearer’s head. The lanyard or connector must be attached in a manner that prevents the operator from free-falling more than 6 feet or contacting a lower level. This is required by 29 CFR 1926.502(d)(16).
Never attach a lanyard to an adjacent structure, pole, or equipment outside the platform. 29 CFR 1926.453(b)(2)(iii) provides that belting off to an adjacent pole, structure, or equipment while working from an aerial lift shall not be permitted. There is no manufacturer-permission exception.
What control and safety function tests are mandatory?
You must test both ground and platform controls. 29 CFR 1926.453(b)(2)(ix) requires that articulating boom and extensible boom platforms have both platform upper controls and lower controls. Upper controls must be in or beside the platform within easy reach of the operator. Lower controls must provide for overriding the upper controls. Lower level controls shall not be operated unless permission has been obtained from the employee in the lift, except in case of emergency. Unauthorized use of lower controls is a frequently cited violation during rescue attempts or when ground personnel try to reposition an occupied platform. The controls must also be plainly marked as to their function.
A valid inspection requires you to actually touch and test the machine. You cannot sign off on a checklist from a distance. Run a full function test of both ground and platform controls. Test raise, lower, rotate, and drive functions. Confirm that the lower controls can override the upper controls if a ground rescue becomes necessary. Verify the controls are plainly marked as to their function. If any label is worn off or illegible, that is a deficiency that must be corrected before use. Test the emergency descent capability and manual lowering controls. When a loss of power or hydraulic pressure occurs, operators must know how to initiate safe descent. Pre-use inspections must verify that these systems work.
What load and travel-position checks does OSHA mandate?
You must verify the manufacturer’s boom and basket load limits. 29 CFR 1926.453(b)(2)(vi) states that boom and basket load limits specified by the manufacturer shall not be exceeded. Compare the total weight of everyone and everything on the platform against the legible capacity figure on the nameplate. The capacity figure includes all personnel, tools, materials, and equipment. Do not guess.
Before moving an aerial lift for travel, you must inspect the boom and outriggers. 29 CFR 1926.453(b)(2)(xii) requires that the boom be inspected to see that it is properly cradled and outriggers are in the stowed position before the lift is moved for travel. Manufacturer manuals and ANSI standards supplement that duty by specifying that the boom should be in the lowered or stowed position during travel. Do not move the truck when the boom is elevated in a working position with workers in the basket unless the equipment is specifically designed for that operation.
Why is pencil whipping one of the fastest ways to get cited?
Pencil whipping is the practice of checking off inspection boxes without actually performing the inspection. It is a common and high-priority OSHA violation. Operators must perform a thorough, documented inspection that includes physical verification of all systems and controls. OSHA compliance officers see this violation when they compare signed checklists to the actual condition of the machine. If the brakes are soft or the emergency lowering does not work but the sheet says everything is fine, the citation is immediate. If you did not look at it, touch it, and test it, do not check the box.
How do you document the inspection so it holds up?
Record the date, the specific machine identifier, the operator name, and every system checked. Note any deficiency found and the corrective action taken before the lift is placed into service. The record should demonstrate that you performed a physical walk-around and a full function test, not merely that a piece of paper exists. Photographs of deficiencies can strengthen the record, but they do not replace the written verification that the correction was completed before use. Your documentation should answer three questions: who inspected it, what did they check, and what did they do about deficiencies. Retaining documentation is called for by the ANSI/ASSP A92 consensus standards and is sound practice. Keep the record with the project files or your equipment log.

FAQ
Who is allowed to operate an aerial lift after the inspection is complete?
Only authorized persons shall operate an aerial lift under 29 CFR 1926.453(b)(2)(ii). In general industry, 29 CFR 1910.67(c)(2)(ii) requires that only trained persons operate the lift.
Can you use a boom lift if the capacity plate is painted over or missing?
No. If the capacity plate is painted over, scratched, or missing, the machine should be taken out of service until the nameplate is restored to legibility under the manufacturer’s instructions and the ANSI/ASSP A92 consensus standards. While a defaced plate is not in itself an OSHA violation of 29 CFR 1926.453, you still must know and follow the manufacturer’s boom and basket load limits under 29 CFR 1926.453(b)(2)(vi). Operating without knowing the limit is a risk you cannot take.
Does OSHA require the operator manual to be stored on the machine?
No. OSHA’s aerial lift standards impose no manual-storage or manual-presence condition on operation under 29 CFR 1926.453 or 1910.67. The ANSI/ASSP A92 consensus standards and manufacturers’ instructions call for the operator manual to be kept on the equipment in a weather-resistant compartment, and it is sound practice to keep it there.
Do scissor lifts fall under the same aerial lift inspection rules?
No. Scissor lifts are not vehicle-mounted aerial lifts under 29 CFR 1926.453. They are regulated as mobile scaffolds under 29 CFR 1926.452(w). The daily control test and walk-around in this checklist apply to boom-supported aerial lifts such as extensible and articulating boom platforms.
