A blast in a confined space can cause more serious injuries compared to a comparable blast in an open space. Even an open window or door can significantly reduce injury potential.


A blast in a confined space results in:

(1) higher pressures for a longer period, since there is less dissipation of the blast wave and the wave is reflected off the walls

(2) flying debris that can ricochet off the walls

(3) toxic gases that may reach a higher concentration

(4) collapse of wall or ceiling

(5) a higher temperature


A blast in a confined space causes:

(1) more injuries

(2) worse injuries

(3) a higher mortaltiy
