It seems that a few people know how to specify safety requirements. The reason that I was surprised in the FuSa project was that many engineers don’t understand what our safety requirement shall be.
if you have a trouble with writing safety requirements, then this paper will give you a benefit how to start.
It is not enough though, but it is useful. Example in this paper helps you to understand better. but it is somewhat simplified, so it looks less practical.
