At present, one of the activities of civil defense is to increase the level of protection of critical and potentially hazardous objects, ensuring the sustainability of their functioning in emergency situations. However, these days there are no ways to assess the level of protection of potentially hazardous objects. The objective of the article is to present the approach to the substantiation of the complex protection criterion of the objects of industry. In pursuing these aims, the authors propose the approach based on energy methods and the interrelated parameters of the damaging factor and objects of exposure. At the same time, the interrelated values of the reduced pressure and impulse form some number, which can be divided into several areas, correlate their values with each other, and based on this conduct the quantitative assessment of the level of the object protection.
Obtained values must be interpreted in terms of practical application. For this purpose, the scale has been developed for assessing values of protection criterion, which allows to correlate them with the level of buildings and structures destruction. Substantiation of the protection criterion and building the scale for its value assessment allowed to develop the algorithm for conducting operational evaluation of the effects of the air blast wave on the object of industry. In addition, using the protection criterion it is possible to conduct the quantitative assessment of the activities to improve protection of the main production assets at the development of civil defense engineering and technical activities.
