In August, the Occupational Safety and Health Administration said that Seaworld showed indifference or intentional disregard for employee safety by exposing workers to drowning hazards when they interact with killer whales.
The agency fined SeaWorld $75,000 and recommended that trainers not be allowed to have any physical contact with Tilikum unless protected by a physical barrier.
In response, SeaWorld officials say they are building fast rising false bottom floors capable of lifting whales and trainers out of the water in an emergency.
At the park, many visitors seemed less interested in safety.
