While not incorporated by reference by OSHA, ANSI-92-2019 requires that occupants of all mobile work elevated platforms (MEWP) such as scissor lifts and boom lifts be provided an awareness level training and how to handle the lift in the event of an emergency. The operator is required to provide instructions or ensure the occupant has the appropriate level of awareness to be in the lift safely. The occupant is only allowed to operate the controls of the MEWP in the event the operator becomes incapacitated.
