Dust explosions pose a serious hazard to both personnel and equipment in industries that handles combustible powders. Although prevention and mitigation technology of dust explosions has progressed greatly, continual accidents in the process industries demonstrate the need for improved knowledge in this area (Mercan, 2016; Russo et al., 2017). On July 16, 2007, a primary explosion followed by secondary explosions happened in the Cordero mill (Italy) and 5 persons died (Marmo et al., 2012).

The main features of Lithium-ion (Li-ion) batteries are high energy and power density, which make this storage technology suitable for portable electronics, power tools, and hybrid/full electric vehicles. Moreover, during conditions that lead to failure, Li-ion battery cells could undergo into a process called thermal runaway, which has resulted in numerous fire accidents. Thermal runaway implies a rapid increase in battery cells temperature, accompanied by the release of flammable gases. These flammable gases could be easily ignited by the battery’s high temperature, resulting in a fire.

Pipelines are the most efficient method of transporting large quantities of hydrogen, and the low volumetric energy density of gaseous hydrogen requires that the gas must be compressed to extremely high pressure to be used as a transport fuel. The failure of high pressure hydrogen gas pipelines and subsequent explosion may induce heavy damage to buildings. In this paper, such an issue is addressed for existing reinforced concrete framed buildings and tuff stone masonry buildings.
