Enclosed spaces significantly amplify the effects of a blast, primarily through the increased levels of blast pressure impact. When an explosion occurs in a confined area, the shockwaves generated cannot dissipate freely as they would in an open environment. This confinement enhances the pressure waves and can lead to more severe injuries and fatalities among individuals within or near these spaces.

The dynamics of the shockwave are altered; instead of being dispersed, the energy is reflected off walls, floors, and ceilings, concentrating and intensifying the force that reaches individuals. This phenomenon can lead to greater impact on the body, potentially resulting in more critical injuries compared to an explosion in an open area.

In contrast, decreased shrapnel spread might occur simply due to the physical confinement, but that does not negate the fact that pressure increases overall. A lower mortality rate and less thermal expansion are not typically associated with enclosed explosions; in fact, mortality rates can be higher in closed spaces due to the combination of higher pressure and potential for flying debris. Overall, increased blast pressure impact is the primary effect observed during such events in confined spaces.
