This paper concerns the meaning of 'safe' and current practice regarding safety analysis, safety case and safety assessment. The intention is to state some diagnosis, i.e. to identify an illness or problem from its signs and symptoms and to conclude from such an act. Safety engineering practice and the way of conceptualizing the problem is alarming the author when he is trying to be clear as far as possible in saying what they are doing and assuring. Some work in progress is mentioned. This paper is written to stress the difficulty of defining the framework for systems safety engineering and assessment by exploring some of the elements of the engineering and assessment processes and use this as a general diagnosis of the current practice in the context of the Cenelec railway norms. In addition two tools are shortly discussed, based on the author experience, help in the safety argumentation development.
