چکیده مقاله:

Introduction: Iran as a developing country is experiencing the industrialization process quickly and is also exposed to different chemical hazards. The increasing trend of industrial chemical accidents in the recent years confirms the above statement. Producing, transporting, storing and applying various types of chemicals causes to threaten the residents’ safety. The aim of this study is assessing the human vulnerability in chemical accidents using software simulation of releasing Chlorine gas scenario.Methods: This cross sectional study using mix method (qualitative and quantitative) was conducted in 4 phases during 2016-2017 in Shourabad, Ray County, Tehran province. Four phases of study included systematic review, software simulation based on chemical accident scenario, Fuzzy Delphi-AHP study and assessing the human vulnerability in the area under study by a researcher-made questionnaire. In the pilot and main study, the samples were 130 and 710 respectively that were selected by systematic random sampling. Then the descriptive and analytical statistical tests including percent, mean, chi-square, ANOVA and Independent Samples T Test were used for analyzing data by SPSS 22.Results: The AHP results showed that the importance of indicators of social vulnerability is 2.1 times more than the physical vulnerability indicators in industrial chemical accidents. Also, the vulnerable groups possessed the highest weight values (0.118) among the social vulnerability indicators and preparedness of the region for chemical hazards held the highest weight (0.075) of physical vulnerability indicators.The statistical analysis showed that the human vulnerability as the main variable has the significant relation with other variables such as nationality, rural and urban areas, economic situation of households, the distance between housing to exit main road, the nearest health center in the area understudy (P-value<0.01). Conclusion: The results showed that Ray County was not prepared for chemical accidents both in industrial and residential areas. It’s necessary to decrease the distance between the residential areas with health-care centers and access to health services in the area understudy. Also, additional comparative studies are needed to develop the appropriate set of indicators of human vulnerability in man-made disasters.
