Knowledge engineering of risks to cosmonaut’s health, based on the cascade scheme of organism protection for hazardous occupations

Successful identification of risks and threats to health and working capacity from hazardous occupations, such as cosmonaut, and choice of preventive and compensatory tactics depend largely on timely evaluation and parrying of risk-bearing situations inherent in an occupation and working conditions. The methodical platform for classification, unification and ranking of the multitude of detrimental environmental factors provides ample opportunities for the broad community of experts in labor safety. Aspects of modeling expert knowledge in medical support of hazardous occupations are discussed in light of the cascade scheme concept. Alternatives of expert risks knowledge retrieval and digital presentation and methods of ranking undesired events have every right to be integrated into the screening for prevention and compensation of deterioration of cosmonaut’s ability to work due to occupational and ecological factors.
