Development tendency for accident situation in building industry

A thorough analysis of the accidents in the Polish building industry in years 1992–2004 is presented. The accident situation, if assumed to be a homogeneous phenomenon, is estimated based on the accident rate of minor, serious and fatal accidents and all the accidents jointly as well as based on 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 nonhomogeneous phenomenon. It is constructed the model of development tendency for a phenomenon according to the information on the accident situation expressed by the accident rate and the accident seriousness index in the years 1992–2004.
