n the paper, according to the analysis of statistical data, correlation between the amount of occupational injuries and occupational
diseases in Ukraine within last 5 years is defined. Also, using methodology of the International Labor Organization
correlcation between the amount of accident fatalities and general number of accidents in Ukraine and EU countries (Austria, Great
Britain, Germany, Denmark, Norway, Poland, Hungry, Finland, France) is defined. It is shown that in spite of the positive dynamics
of decreasing amount of occupational injuries, the number of occupational diseases in Ukraine always increases. The comparative
analysis of the ratio of the number of accident fatalities to the total number of registered accidents showed that, on average, Ukraine
exceeds the EU countries by this indicator by 100 times.
It is noted, that such negative indicators (in particular, increasing amount of occupational diseases), may occure because of
imperfect methodology for identifying the risks of professional dangerous.
Also, it is ascertained that basing on the existed methodology, the identefication process of occupational dangerous is
quite subjective, which reduces objectivity of conducting quantitative assessment. In order to eliminate defined drawnbacks it is first
time proposed to use corresponding integral criterion to conduct the process of quantitative risk assessment
To solve this problem authors formulate and propose an algorithm of improving methodology of a process of analysing dangerous
and harmful production effects (DHPE) which are the mainest reasons of occupational dangerous.
The proposed algorithm includes implementation of four following successive steps: DHPE identification, indication of their
maximum allowed threshold of concentrations (levels), identification of the sources of identified DHPE, esimation of consequences
The improved proposed methodology allows indentify risks of occurrence occupational dangerous in systems "humantechnical
system-environment" even on the phase of its designing when dangerous and harmful manufactured factors are unknown
