Cal/OSHA Deputy Chief of Field Operations Mark Carleson said the investigation showed mechanical error was likely the largest contributor to the accident. Carleson said inspectors found the crane used at the mall was out of adjustment.

Additionally, as part of its two-month investigation, Cal/OSHA inspectors found the company failed to provide proper safety measures on the machinery and employed improper operating practices. Cal/OSHA cited the company for one willful violation for not having an inoperative crane horn. The violation carries a $5,625 penalty.
Other citations include:
California law provides that a company may appeal Cal/OSHA citations and penalties within 15 working days to the Occupational Safety and Health Appeals Board in Sacramento.
