Quantitative Risk Evaluation of Fatal Incidents in Construction Based on Frequency and Probability Analysis

Comparative Analysis of Degree of Risk between the Frequency Aspect and Probability Aspect Using Integrated Uncertainty Method Considering Work Type and Accident Type in Construction Industry

“…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]. According to the report on industrial accidents in 2020 by the Ministry of Employment and Labor (MOEL) in South Korea, the number of injuries and fatal incidents in the construction business is 24,617 and 458, accounting for 26.6% and 51.9% of the total, respectively [6].…”

“…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 degree of risk can be assessed by quantitative analysis and qualitative analysis, simultaneously [2]. The quantitative analysis is presented by the frequency of fatal incidents based on data in order to be reliable.…”

“…The quantitative analysis is presented by the frequency of fatal incidents based on data in order to be reliable. The qualitative analysis is presented by the probability of fatal incidents which is evaluated by experts' judgement [2,14]. The degree of risk should be evaluated as an aspect of the frequency of fatal incidents and probability of fatal incidents in consideration of construction work and accident type to strengthen safety management [14][15][16].…”

“…The management of construction safety should reflect the characteristics of the construction accidents based on the construction work type. In practice, because the construction risk is evaluated by unskilled labor, the safety management costs are not properly allocated [2]. It is important to accurately evaluate the degree of risk reflected in the characteristics of construction type at the preconstruction phase [2].…”

“…In practice, because the construction risk is evaluated by unskilled labor, the safety management costs are not properly allocated [2]. It is important to accurately evaluate the degree of risk reflected in the characteristics of construction type at the preconstruction phase [2]. This research aimed to confirm the degree of risk, comparing between the frequency of fatal incidents and probability of fatal incidents (also known as fatality rate) using an integrated time series and estimation method.…”
