The complicated story starts back with the 2010 death of SeaWorld trainer Dawn Brancheau, the focus of the CNN documentary "Blackfish." OSHA fined SeaWorld of Florida after finding they violated OSHA's "general duty clause," which requires that employers furnish employees a place of employment that is free from recognized hazards that are causing or are likely to cause death or serious physical harm. Trainers were banned from entering the water with orcas as a result.
The complaint reads:
MSQ [Miami Seaquarium] is a marine entertainment facility that continues to require trainers to swim with, ride on top of, and otherwise interact in close physical proximity with an unpredictable and inherently dangerous orca named Lolita. In doing so, MSQ exposes its employees to a deadly recognized hazard that is easily abated.
