Abstract
Fatal incidents in the construction business are higher than in other industries. Previous studies concentrated on the frequency of fatal incidents based on safety management, however, the probability of fatal incidents might be more important than the frequency of fatal incidents. For instance, certain work types have low fatal incident cases but show a high probability of fatal incidents, which means they are riskier than others. The purpose of this study is to analyze the level of risk by comparing the frequency of fatal incidents and probability of fatal incidents for 27 types of work and 18 types of accidents using an uncertainty analysis. This study is carried out in five stages from the collection of data to conducting the statistical analysis. The result of the research shows the estimated rank of frequency and probability for work and accident type, respectively. For instance, ‘reinforced concrete construction work’ (66.5 fatal incidents) showed the highest frequency work type, and ‘scaffold and demolition work’ (28.65‱) showed the highest fatality rate. This research addressed the uncertainty problem using an integrated time series and estimation method to compare the degree of risk from the viewpoint of frequency and probability aspects in the construction business.

Publisher’s Note: MDPI stays neutralSince the construction business has been a representative labor-intensive industry, the rate of fatal incidents is higher than other business sectors [1,2,3,4,5]
The statistical analysis was conducted to determine differences between 27 work types considering the frequency of fatal incidents and probability of fatal incidents using SPSS 18

Summary
Since the construction business has been a representative labor-intensive industry, the rate of fatal incidents is higher than other business sectors [1,2,3,4,5]. The number of injuries and fatal incidents in the construction business is 24,617 and. Before taking action to reduce and eliminate fatal incidents in the construction business, the degree of risk should be evaluated in advance. When identifying the degree of risk in consideration of work types and accident types, the prevention action can be conducted to reduce and eliminate the occurrence of fatal incidents [7,8,9,10,11,12,13]. The qualitative analysis is presented by the probability of fatal incidents which is evaluated by experts’
