OSHA does not list any specific requirements or qualifications for aerial lift trainers. When it comes to the execution of aerial lift training, OSHA defers to the American National Standards Institute, which details these requirements in A92.24-2018 - Training Requirements For The Use, Operation, Inspection, Testing And Maintenance Of Mobile Elevating Work Platforms.
In this regulation, ANSI states:
"All training shall be delivered by a qualified person who is experienced with the particular classification of MEWP and knowledgeable regarding the laws, regulations, safe use practices, manufacturers requirements, and recognition and avoidance of hazards associated with MEWPS."
ANSI defines qualified as:
Aerial Lift trainers must be both qualified and experienced on the MEWP they will be certifying employees on.
"A person, who, by possession of recognized degree, certificate or professional standing, or by extensive knowledge, training and experience, has successfully demonstrated his / her ability to solve or resolve problems to the subject matter, the work, or the project.”
