By matching domestic ODA projects for specific implementation in accordance with the 2020 Fire and Disaster Prevention Agency Facility Infrastructure Master Plan and 2030 Vision, a social safety net construction project in Vietnam, its business feasibility was analyzed. Vietnam is undergoing rapid change and urbanization. As a result, demand in the firefighting sector is expected to increase rapidly. Because there are no domestic manufacturers of firefighting vehicles in Vietnam, the demand is largely satisfied through imports; however, the firefighting vehicles and additional devices provided through this ODA project should greatly contribute to the promotion of domestic exports. To represent the environmental factors that can cause fires in 58 provinces, the selection of project areas to support firefighting vehicles is based on population, jurisdictional area, population density, age of firefighting vehicles, number of firefighting targets, and number of firefighting vehicles in the past four years; the trend of reinforcement of firefighting vehicles and regional characteristics is determined. Twelve provinces in Vietnam were selected in the same way as the selected areas to support firefighting vehicles. This ODA project is expected to provide an opportunity to improve the legal and institutional aspects of the firefighting and disaster prevention field in Vietnam by applying domestic advanced firefighting force deployment standards.
