ORLANDO, Fla. (AP) - A federal agency has cited Disney with three safety citations totaling $69,000 related to the death of a mechanic who died in March while doing work on a ride at its Animal Kingdom park.
    
Each of the violations, which were officially issued last week, is deemed serious by the Occupational Safety and Health Administration. A probe was opened after a 52-year-old park worker was struck and killed by one of the Primeval Whirl ride's four-person vehicles while doing maintenance on the roller coaster.
    
Investigators say in the official citation that gate sensors were not maintained and that guardrails weren't installed properly.
    
A Disney spokesman says they have thoroughly reviewed the findings and have implemented several safety enhancements to Primeval Whirl to address the concerns raised by OSHA.
