National Safety Stand-Down 2017: What are the Inspection Requirements for Aerial Work Platforms?

GS5390_YD1C0048-Man and Engine tray pull out-VS-2cc (1)Performing equipment inspections is essential for ensuring the safety and productivity of any piece of aerial work platform equipment. One of the challenges lift equipment owners face is knowing how often to perform inspections on their aerial work platforms.

ANSI standards state that routine inspections should be performed frequently, as well as annually. Here’s a breakdown of what tasks should be performed at each inspection point:

Frequent inspections

Frequent inspections must be performed in accordance with the manufacturer’s instructions on an aerial platform:

  1. That was purchased used.
    • This inspection shall be accomplished unless it is determined that the frequent and annual inspections are current
  2. That has been in service for three months, or 150 hours, whichever comes first
  3. That has been out of service for a period longer than three months

The inspection shall be made by a person qualified as a mechanic on the specific type aerial platform. The inspection should include, but not limited to, the following:

  1. All functions and their controls for speed(s), smoothness and limits of motion
  2. Lower controls including the provisions for overriding of upper controls
  3. All chain and cable mechanisms for adjustment and worn or damaged parts
  4. All emergency and safety devices
  5. Lubrication of all moving parts, inspection of filter element(s), hydraulic oil, engine oil and coolant as specified by the manufacturer
  6. Visual inspection of structural components and other critical components such as fasteners, pins, shafts and locking devices
  7. Placards, warnings and control markings
  8. Items specified by the manufacturer
  9. Emergency lowering means


Annual inspections

Z-60-37DC-160Annual inspections must be performed on the aerial platform no later than thirteen (13) months from the date of the prior annual inspection, and the inspection shall be in accordance with items specified by the manufacturer for an annual inspection.

The inspection needs to be done by a person(s) qualified as a mechanic on the specific type of aerial platform. And, an aerial work platform should not be put into service until any malfunctions and/or problems discovered during the inspection have been corrected.

    We have a Genie Z20/8 purchased in 1998. What are OSHA and other requirements inspecting this equipment, frequency, operation etc. Please provide regulation stating the requirement if possible. A quick review of OSHA aerial lift requirements does not stat and inspection frequency other than daily before use.

      Hi Ronald,

      Essentially, the OSHA Regs require the aerial lift be maintained and operated according to the manufacturer’s instructions. Here is a link to an OSHA Quick Card on this subject (refer to the 2nd bulletin point): All of the maintenance and inspection procedures for the Z-20/8 can be found in the machine’s service manual. All of our manuals can be accessed from

      The OSHA regulation that applies to aerial lifts is CFR 29, Part 1926.453 “Aerial lifts.” All of the current ANSI standards are referenced in this section as “national consensus standards” (found in non-mandatory appendix “C” of the same section). OSHA states that these new ANSI standards “…are considered to provide employee protection equivalent to that provided through the application of ANSI A92.2-1969.” The 1969 ANSI standard was the only relevant standard in existence when OSHA first drafted the section for aerial lifts. Importantly, 1926.453 is not considered by OSHA or industry experts to be as comprehensive a standard for design or use as the ANSI standards.

      Let us know if you have any further questions.
