The safe community is now at time of globalisation very dependent on a safety level of critical infrastructure ensuring the territory by basic services necessary for humans´ live as there are energy, water, food, information etc. Series of events from recent years connected with critical infrastructure failures showed its high importance. The critical infrastructures represent multistage mutually overlapping systems, i.e. big complex systems, the type of which is a systems system. The paper presents the model for critical infrastructure safety management based on this reality and it shows the way how simply to determine the criticality of individual infrastructures and the whole critical infrastructure.

This paper describes the approaches development of organizations to environmental protection through several stages from complete passivity, over so-called the reactive approach to the proactive principles. The passive approach relies on the power of nature to dispose of waste by own assimilative capacity, the reactive approach is based on a strategy of control and management especially in relation to the legislative measures and the proactive principle, applied in developed countries since the nineties of the twentieth century is based on the fact of prevention of pollution occurrence being cheaper and more effective than to subsequently remove it, or bear the consequences. A proactive approach focuses on eliminating problems before they have a chance to appear and a reactive approach is based on responding to events after they have happened. The difference between these two approaches is the perspective each one provides in assessing influences and their impacts. The aim of environmentally oriented management based on the proactive principles is use the special management tools and methods application are the subject of this contribution.
