Abstract. The article is dedicated to the mathematical definition of durability of a mechanical system taking into account the appearance of extreme loads acting on it for definite time. Materials of research represent a continuation of several works of authors on the development of methods and techniques for determining reliability and durability to control safety by a mechanical system - load-bearing structure of the bridge of metallurgical crane based on interdisciplinary approach.
The emergence of ``surges'' when loading mechanical systems for the period of time is taken by independent rare events that are subject to the law of K. Pearson -distribution.
The resulting relationship takes into account the probability of a single load excess of the permissible level (the emergence of ``surges''), arising from system operating conditions and mode of loading, which can cause the emergence of such ``surges''.
Mathematical modeling and determination of durability of a mechanical system in case of extreme loading conditions allows making the right engineering decisions to control technogenic safety of certain productions or their major components.
