ABSTRACT
ABSTRACT Accident analysis is an important source of information for developing prevention strategies and making decisions. This chapter is based on the author’s previous work on the accident analysis of occupational fatal falls. In the most recent study (Chi et al. 2014), each fatality was analyzed based on individual factors (i.e., age, gender, and experience), falling site, falling height, company size, and the accident causes. Each of these contributing factors was derived from accident reports of 411 work-related fatal falls occurring during 2001-2005. Given that most fatal accidents involved multiple events, our previous study coded up to a maximum of three causes for each fall fatality and applied a fault tree analysis to represent the causal relationships among events and the causes. After the Boolean algebra and minimal cut set analyses, accident causes associated with each falling site can be presented as a fault tree to provide an overview of the basic causes that could trigger fall fatalities in the construction industry. Graphical icons were designed for each falling site along with the associated accident causes to illustrate
