The fact that the head of another Swedish wildpark got convicted of manslaughter over the death of a keeper. Given that, it would be hard for those in charge to allow any worker to take risks to save these escaped animals. Even if the worker was willing to do so.

That answers how much risk we're willing to tolerate.

That answers how much risk a certain institution is willing to tolerate. Institutional tolerances differ from individuals IME; many institutions are risk-averse because people seek to protect their jobs, especially if it has a culture of blame.

Would you risk your life to save a chimpanzee? I would to some extent. A peaceful, friendly chimp; and with instruction from an expert; I might take the risk. An angry chimp would be unlikely to receive aid that involves risk. Forget violence; what about wading into a flood to rescue an unconscious chimp?
