- 1 . Good efternoon everyone I am from sungkyunkwan university in southkorea. So. From now I will present my research about vulnerability assessment in case of chemical accident. Recently there are huge chemical accident in japan and china. also in korea chemical accident occurs every years and someone is dying The trait of chemical accident we cannot calculate exact time and range of damge these matter cause huge damage without preparedness. / So…. Let’s go on next page
- 2. my presentation is organized background of research and method and result using GIS
- 3. korea has been experience chemical accident. Streadly people have been dyng a lot 20 12 hydrogen floride release accident in gumi city in korea lead people’s attention. All nations care about the safety of chemical factory near their living area. Also they start to recognize the danger of the chemicals. Also People want to know the information about the hazard. So Korea made rules. .one is open hazardous material platform and one is OCA regulation
- 4. the main reason of the chemical accident in south korea are deteriorated industrial complex. And also the chemicals volume have been increasing since 19 98. These chemicals have not managed systemically until 20 13
- 5, the research of chemical disaster has been doing. The CCPS in America working on risk assessment of chemical accident in case of scenario and calculate the possibility using hazop method. It could calculate likeyhood about mechanical fault. EPA also is doing Offsite consequence analysis for outside of factory that save the life for an emergency and predict the consequence of disaster And fenying studies on human vulnerability as you can see. Using the GIS the right side In korea also do the OCA. from 20 11 The methodology based on DEGADIS and Gaussian theory We call Caris Program. We sumit the report to ministry of environment of korea And experts give alternatives to increase resilience
- 6. my research are based on this theory. To risk assess . there are Three component hazard and vulnerability risk element. As you can see. We know the hazard. hazard could be rainfall, rockfall, chemical releasing, flood. In this study focused on constructing vulnerability and risk element. and risk element could be people , building, sometimes train, forest. It is the Target could get damaged from the hazard./ The vulnerability Is the characteristic of risk element in this work Risk element is people..human . so the vulnerability is concerned with people’s characreristic It could be age. Site, education, awareness of escape route, shelter position . So vulnerability can be anything to effect the people trait. So In this study construct the spatial information combining risk element and Vulnerabbility to make map
- 7. So there are 4 process to get result. Calssifing the vulnerability can be used And building, constructing the spatial information. Simulating impact area using Aloha program from EPA and Multicriteria method
- 8. as you can see the research methology follow these steps first collecting the statistics data ….second making chemical release scenario and aloha simulating and then settting the indicator and value and then verification of constructed spatial information and last… seesment the vulnerability
- 9. to construct spatial information. collecting the data data are age. And numer of workers/ rate of working people in census track. and respond facility site and building layer and landuse map to verify the spatial information
- 10. to simulate the chemical release I use the aloha program from EPA. You can see the Input data on the table. The input variable. choose the chemicals wind speed humidity..and so on. On the Right side /the result aloha program shows like this / we can know the range of damage
- 11 so I classify 4 vulnerability when the chemical release accident happen. Social dynamic physical site-dependent are used for vulnerability mapping. the indicator I use are age. Hospital, firestation , impact of aloha result and proximity of distance from factory …. The assigned value are normalized
- 12 these three spatial information are used to verify the constructed spatial information SO I confirm the data well made
- 13. this picture show the whole process. Overlay each vulnerability. I apply the constructed data on level 3. I could apply the value for assessment but With no clue I Couldn’t give the value so I gave same value of each vulnerability on lecel 1 and 2
- 14 so this is the result of my study this one for the nighttime vulnerability when the chlorine release accident happen as you can see the high vulnerability on residential site
- 15 but daytime vulnerability is high on the industrial complex because lot of worker is in working place. So WE can see the when and where .we focus on responding emergency
- 16 at last the research classify the vulnerability and use small unit and suggest the daytime vulnerability….I look forward to this study can give the information for responding to save the people’s life / thank you very much
