Industrial demand has intensified production, utilization, and transport of hazardous materials (hazmat). As the production and use of hazardous materials are frequently carried out at different locations, accidents during the transport of hazmats constantly occur. The most critical points on the hazmat routs within inhabited urban or rural areas are centres where the population with increased vulnerability reside. This study aims to assess the exposure of people with disabilities to the impact of hazmat road accidents, in order to provide evidence-based knowledge necessary for the establishment of competent disaster preparedness procedures. A case study was developed for ammonia release from a tanker truck in the vicinity of the Institution for Children and Youth with Disabilities in Veternik, a suburban settlement of Novi Sad, Serbia. An integrated methodology for the risk assessment of the identified problem was proposed focusing on environmental and human-induced variables with a significant impact on the hazard magnitude. The simulation conducted with ALOHA (Areal Locations of Hazardous Atmospheres) confirmed assumption that the combination of high temperature and low wind speed can cause the worst-case scenario i.e. to expose a larger surface area to the influence of released ammonia. In addition, hazard maps were developed by importing the simulated area of ammonia spread into Quantum GIS (QGIS) software.
工业需求加剧了危险材料（危险品）的生产、利用和运输。由于危险品的生产和使用经常在不同的地点进行，因此在运输危险品时经常会发生事故。在人口密集的城市或农村地区的危险品路线上，最关键的地方是人口脆弱性增加的中心。本研究旨在评估残疾人接触危险品道路事故影响的情况，以便为制定有能力的备灾程序提供必要的循证知识。在塞尔维亚诺维萨德郊区的 Veternik 市，针对一辆罐车在残疾人儿童和青年机构附近发生氨气泄漏的情况，开展了一项案例研究。提出了一种综合方法，用于评估所确定问题的风险，重点关注对危险程度有重大影响的环境和人为变量。使用 ALOHA（危险大气的区域位置）进行的模拟证实了这样一种假设，即高温和低风速的组合可能会导致最糟糕的情况，即更大的表面积会受到释放的氨气的影响。此外，通过将模拟的氨气扩散区域导入 Quantum GIS（QGIS）软件，还开发了危险地图。
