[Principles of the sanitary and housekeeping arrangements in space flight environments]

Significant changes in the functional state of crewmembers during prolonged space missions necessitate corrections to be made in the scope and methods of sanitation and housekeeping arrangements. Due to the fact that in space flight automicroflora representatives may acquire greater importance as possible pathogenic agents, procedures providing body cleanliness should include both physico-chemical exposures and direct skin microflora treatment. On the basis of pertinent investigations the authors have developed selection criteria and requirements for detergents and disinfectants that may be used in prolonged space flights.
