ORLANDO, Fla. (AP) - Sea World Orlando has been fined $75,000 for three safety violations that led to the death of a trainer by a killer whale last February.

The federal Occupational Safety and Health Administration issued the citation on Monday.

One of the three violations is considered "willful," or shows indifference or intentional disregard for employee safety. The willful citation was given for exposing workers to drowning hazards when interacting with killer whales.

Two serious citations were given, including one for failing to install a stairway railing system beside the stage in Shamu Stadium.

Trainer Dawn Brancheau died when a killer whale grabbed her hair and dragged her into a pool.

A SeaWorld spokesman didn't immediately return a call seeking comment.
