A blast wall is a barrier designed to protect vulnerable buildings or other structures

and the people inside them from the effects of a nearby explosion,

whether caused by industrial accident, military action or terrorism.

blast walls have the following properties:

-A non-deforming upright wall will significantly reduce the peak blast overpressure and impulse in an area between 4 and 6 wall heights behind it
-Similar protection occurs at greater distances behind the wall, but to a diminishing extent
Blast walls perform best if the explosion is relatively close to the front of the wall
-"Canopied" walls (with a top section overhanging the front face) show some improved blast protection over plane walls
-A 90-degree canopy is more effective than a 45-degree one
-Walls containing sand or water work well, and cause little damage if they fail
-A wall has to stay intact long enough to "interact" with the blast in order to have any effect
