Coal handling system in thermal power plants has a high accident rate, so workers are likely to be easily exposed to hazard factors. Therefore, it is necessary to identify risk factors by observing workers" work behavior frequently. Moreover, improvement activities for risks are needed according to the priority of the risk. To this end, AHP (Analytic Hierarchy Process) is applied to evaluate the risk of work in the coal handling system and to use it in the safety activities of workers. AHP analysis is a technique that analyzes the importance through pairwise comparison after decomposing and stratifying major factors in detail when there are multiple and complex evaluation criteria in decision making. Using the AHP analysis technique, we intend to classify the risks and derive measures to reduce risk. In this research paper, the risk factors felt by workers during the operation of the coal handling system, which is the conveyor transfer process of bituminous coal, were discovered through on-site surveys. Furthermore, the degree of the risk factors discovered targeting workers was surveyed and analyzed. Based on the survey results, AHP was conducted by structuring the problem into four levels of hierarchy: facility process, injury types, hazard factor, and 4M classification. AHP method was conducted in the form of a questionnaire survey targeting experts with abundant experience and technical skills in the operation of coal handling system. In addition, the degree of risk was quantified through a pairwise comparison by risk factor, and usefulness was secured through weighting analysis and relative importance. Since the risk assessment results of AHP (Analytic Hierarchy Process) through the expert survey were similar to the analysis results obtained from the survey conducted on workers in the field, it was judged that the effectiveness of the assessment technique was verified. Therefore, it is expected that the risk assessment results of AHP through the expert survey can be used for quantitative evaluation of improvement results, such as checking the occurrence of a disaster and the incidence rate. In addition, AHP can analyze the risk priority by deriving accident risk factors that are likely to occur to workers such as similar power-plant accidents or Near Miss. AHP can analyze the priority of risk from time to time through a prompt pairwise comparison of risk factors in the workplace. This analysis result is expected to contribute greatly to the safety activities of workers as well as facility improvement by quickly applying them to the work site.
