abstract: BACKGROUND
  World trends and international organization recommendations point out the necessity of OHS economic appraisal methods improvement in order to ensure effective resources management in companies.
  
  
  METHODS
  Published world literature on economic appraisal results, recommendations of international organizations, results of the own studies on economic appraisal in the field of health and safety at work in the companies in Poland were the background of the economic appraisal model for Polish companies. Several project assumptions have been adopted. The model of the return of the investment, model based on the company participation and some elements of the net costs formula are recommended for Polish companies in order to appraise efficiency of the health investment. The basic ratio in economic evaluation should be cost/benefit ratio. The project of the economic evaluation algorithm has been elaborated.
  
  
  CONCLUSIONS
  The economic analysis of the health protection and safety at work should include clear division between the internal and external costs. The proposed model could be used for the companies management needs in two directions: to microeconomic efficiency appraisal of investment in programs/intervensions in health and safety at workplace and to analyze the influence of the costs of accidents and occupational diseases and costs of preventive programs on finance management on the company level.
