[Protection of workers' health against occupational psycho-social hazards--theoretical models].

Occupational Health Service are not yet equipped with tools which could permit them to include protection of workers' health against occupational psycho-social hazards into their prophylactic activities. The authors present a model of such a system, its objectives and conditions which should be satisfied in order to put the system into operation. The model discussed is somewhat an ideal solution which does not necessarily adhere to the reality but it sets tasks and identifies lines of activities to be carried out at the Department of Occupational Psychology, the Nofer Institute of Occupational Medicine, Lodz. These activities are aimed at monitoring and evaluating of health risk generated by psycho-social factors.
