Risk levels
**!
0 Acceptable risk is accepted in a given context based on the current values of society.
In other words, a risk is acceptable when it is acceptable to the general public.
0 Catastrophic (unacceptable) risk is the level of risk which leads to unwanted consequences in most cases
The Acceptable level of
Individual risk of human death is 10-6
10-6=1/1 000 000
Thus, in the modern society it is normal that 1 person per million dies due certain reason

Topic 2. Implementation of health assessment criteria for safety management
® The main tasks of the SoHA lie in definition of the interactions between human and environment and ways of the impacts of the environmental changes on human health and well-being
® World Health Organization (WHO) defines the health as a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.
Health levels
® Sociological level describes the health of the population in general (humanity, population of the region, citizens etc)
® Group level is defined by specific activities of small sociological groups (families, staff, team, training group).
® Individual level can be explained as the functional or metabolic efficiency of a living organism
