Retrieved from: Occupational Safety & Health Administration Aerial lifts are often used in shipyards and boatyards when the erection of staging is impractical. These boom-supported personnel platforms and bucket trucks (i.e., cherry pickers) may cause worker injuries or deaths. Boom failure, tip-over, falls and ejection may occur if the equipment is not properly used. https://www2.osha.gov/Publications/aerial-lifts-factsheet.pdf
