The purpose of this study is to investigate the individual-level chemical accident response competency through a chemical accident response competency survey of small and medium-sized chemical companies using the developed chemical accident response competency application model. A total of 141 chemical company workers were surveyed and analyzed for results, and the average was 3.18, which was a normal level. For each item, the knowledge competency component(K.C.C.) was 3.23, and the skill competency component(S.C.C.) was 3.45, which was a normal level, but the Ability competency component(A.C.C.) was 2.87, which was measured at an insufficient level. First of all, it is necessary to provide appropriate safety education to prepare for chemical accidents. In addition, it is necessary to improve technologies competency such as handling safety equipment and operating initial response equipment to prepare for chemical accidents. In particular, the level of capability component (A.C.C) should be improved through specialized training for chemical accident response, training for handling response equipment, and safety inspection.
