Abstract

This study examined the status of resident evacuation sites notified to nearby communities, centered on business sites subject to the risk management plan of Incheon, Siheung, and Ansan. Through an analysis of the meteorological data, the direction of improvement of the site selection process for the safe evacuation of chemical accidents was studied. Among a total of 111 evacuation sites, 30 schools were selected the most, and 2-3 sites were usually selected for evacuation. As a result of an analysis of the Incheon meteorological data of 2016, the frequency of occurrences was 18.8525% in the NNE wind direction, 18.0328% in the NNW wind direction, 12.2951% in the WSW wind direction, 9.0164% in the SSE direction, 8.4700% in the SW direction, 6.5574% in the W direction, and 5.7376% in the S direction. The NNE wind direction showed the highest frequency, but the other winds showed a relatively high frequency, indicating that the annual wind direction was not biased toward one side.

인천과 시흥, 안산 소재의 위해관리계획 대상 사업장을 중심으로 인근 지역사회에 고지한 주민대피 장소 현황을 조사하고 기상자료 분석을 통하여 화학사고 시 안전한 주민대피를 위한 장소 선정 과정의 개선 방향을 연구하였다. 총 111개의 주민대피 장소 중에 학교가 30 곳으로 대다수 위해관리계획 대상 사업장이 선정하는 것으로 조사되었으며, 통상 2-3곳의 주민대피 장소를 선정하는 것으로 나타났다. 인천의 2016년도 지상기상관측자료를 분석한 결과 16방위 중 NNE 풍향 18.8525 %, NNW 풍향 18.0328 %, WSW 풍향 12.2951 %, SSE 풍향 9.0164 %, SW 풍향 8.4700 %, W 풍향 6.5574 %, S 풍향 5.7376 % 순으로 발생 빈도가 높았다. NNE 풍향이 발생빈도가 가장 높았지만 NNW 풍향과 차이가 크게 나지 않았고 상반되는 풍향인 WSW 풍향과 SSE 풍향도 비교적 높은 빈도를 나타내고 있어 연간 풍향은 어느 한쪽으로 치우쳐 있지 않는 것으로 확인되었다. 이를 고려하여 화학사고 시 안전한 방향의 대피 장소 선정에 보완점을 제시하였다.
