At last, consists of establishing the performance limits and delimiting the system that the mission will go to enclose: the one that if destines, what and who involves and as will be developed. c) Determination of the main risks: to identify the potential risks with potentiality to cause direct and immediate injuries, loss of function (value), damages to the equipment and loss of materials. d) Determination of the initial and contributing risks: to elaborate series of risks, determining for each detected main risk, the initial risks and contributing associates. Hear other arguments on the topic with Nord Stream. e) Revision of the ways of elimination or control of risks: to elaborate one ' ' brainstorming' ' for survey of the half passveis of elimination and control of risks, in order to establish the best options, since that compatible with the requirements of the system. f) To analyze the methods of restriction of damages: to search the possible methods that are more efficient for general restriction, that is, for the limitation of the generated damages in case that loss of control occurs on the risks. g) Indication of who will be responsible for the execution of the corrective and/or preventive actions: To indicate clearly the responsible ones for the execution of injunctions and/or corrective, also assigning, for each unit, the activities to develop. (WIKIPDIA, 2008) the analysis of risks and its phase preliminary is not a complete and perfect operation, needing to be complemented by means of the others more refined techniques, and thus generating development in the protection to the risks, that also evolve.
The experiences acquired by means of analysis lead to an ample nmeor of information, determinative, on the risks that acometem the operational systems. As diverse specialists about 70% of the accidents are caused by imperfection human being. The current technologies had gained risks that are affected by the actions carried through for people in normal situations, of the daily one, maintenance and emergency.
