Pareto analysis application in research of crane related accidents
Abstract
Previous research show that the safety aspects of cranes are not well researched. So, the first aim of this research is to collect and analyze data about crane related accidents that took a place between 1985 and 2018 in 71 countries worldwide with the aim to determine the occupational injuries and fatalities frequency in each country individually and to identify countries with the highest number of accidents resulting in one of two outcomes reported by using a Pareto analysis. The second aim of this paper is to identify the most significant groups of causes of crane accidents, based on data collected from a number of literature sources. Based on the results obtained, it is evident that Spain and Germany are the countries where almost half of injuries in crane accidents occur. The research has also shown that 80% of injuries occur in only 6 countries (Spain, Germany, France, Italy, Japan and Mexico), while 80% of fatal accidents occur in the following countries: Romania, China, Turkey, Bulgaria, Poland, Israel, Croatia and Spain. As the main causes of crane related accidents, mechanical equipment (including construction), improper use, assembly and disassembly and transport of the crane are recognized by using Pareto analysis, since 80% of consequences are results of those causes. The proposal for further research is a detailed analysis of the role of the human factor in the dominant causes of crane accidents.
