That's an interesting definition. Traditionally, we had several ways of looking at it: 1. Safety contends with accidents like components breaking. Security contends with malice where input is crafted and failures are set up intelligently to do damage unlikely to happen on accident. There's quite a bit of overlap, though. 2. If talking leaks, safety rarely requires confidentiality of data. It's usually integrity or availability that it shares with security. So, a security violation with covert/side channels might not be a safety violation. Just two off top of my head to illustrate the difference.
