Heterogeneous explosions may occur in confined systems, thus leading to confined
explosions. In the present chapter, mechanical and chemical explosions in confined and
unconfined systems are considered, focusing the attention on their consequences by adopting
the TNT-Equivalency method. Additional incidental typologies, such as Pool fire and BLEVE,
are also described.
