Model of develpment tendency of accident situation in construction industry

The thorough analysis of the accident situation in the Polish construction industry in the years 1992 - 2003 is presented. The accident situation, as a homogeneous phenomenon, is estimated by means of the accident rate of: minor, serious and fatal accidents and all the accidents jointly as well as by means of the accident seriousness index. However, the accident situation is not a homogeneous phenomenon. The frequency of the particular kinds of accidents and their structure change over the years. The standardised accident rate (which takes into account all the kinds of accidents and their structure at the same time) is proposed for the estimation of the accident situation treated as a non-homogeneous phenomenon. It is elaborated the model of development tendency of a phenomenon according to the information concerning the accident situation expressed by the accident rate and the accident seriousness index in the years 1992 - 2003.
