Be safe means to live in an environment in which there is no danger.
I Imperative is total-whole safety. History is the witness for the times which are behind us that they are full of starvation, danger and uncertainty.
Human society development generates new, unknown, dangers. Little level of knowledge tells about them that they will be grown in future which leads to negative effects on human and environment.
Total safety is difficult to reach and it is a fact, it requires from us that we should find a way to influence on events in goal of destructive reduction.
The answer is in taking management of risk from danger. The fact that we are in conscience that dangers are everywhere, they make us challenged. Challenged in terms of knowledge why is some appearance dangerous and how it can operate on a man and an environment.
To know that something is potentially dangerous and that can negatively affect on a man and an environment and take some measures to make it less we call it management of risk.
The creation of knowledge about the world around us is basic assumption of safety. Therefore, it is necessary to permanently acquire scientific and professional knowledge in order to introduce the phenomenon and predictions and development of negative events.
