Abstract
In the contemporary society the need for assurance of technological and environmental safety of production facilities (PF), including hazardous ones, is dictated by technological development of the economy. This fact presupposes that the criteria of potential natural factors (geological, hydrological, meteorological) impact should be clarified during the design process. Insignificant number of available scientific generalizations of external factors impact on PF does not allow for making an initial protectability assessment of production complexes and adjacent areas. This research is aimed at developing a methodical approach to considering natural effects (including the extreme impacts) in assurance of PF’s technological protection and environmental safety in the areas adjacent to PF. The use of threshold probability of beyond design basis accident as the main probabilistic criterion is substantiated for decision making on whether to consider the external natural factors impact on PF or not. Along with it, is shown that the specified levels of probability of various natural factors occurrence should be revised upwards with account of detailed computations of accident scenarios at a PF. It is noted that risk management of PF exposure to external natural impacts should stipulate that monitoring of such factors should be arranged and carried out.
Highlights
Due to the intensive technological development of the economy in contemporary society, the issues of environmental and technological safety assurance of production facilities (PF), including hazardous ones, have gained special relevance over the last years
It should be noted that in order to achieve these objectives, it is necessary to set up monitoring of the state of environmental components in the zones of technogenic impact of PFs
When making decision on whether to consider or refuse to take into account the impact of one or another external environmental factor on a PF, the probability of this factor’s effect on generating adverse consequences for both the PF and the environment is normally taken as a guidance [2, 3, 6, 7]
Summary
Due to the intensive technological development of the economy in contemporary society, the issues of environmental and technological safety assurance of production facilities (PF), including hazardous ones, have gained special relevance over the last years. It is the natural factors that in certain conditions determine a list of required actions to ensure PF’s technological protection and environmental safety of their siting areas. In this link a fan effect may be observed when an individual system or structure is exposed to a set of factors, as a result of which the entire system can become inoperable and the environment can be impaired intolerably. The aim of this research is to develop a methodical approach to considering natural impacts (including the extreme effects) in assuring PF’s technological protection and, and indirectly, environmental safety in the areas adjacent to PF
