BLAST RESISTANT BARRIER
A blast wall is simply a barrier used to protect the facade of a vulnerable structure and its occupants from debris and fire during an explosion or attack. The danger might come from an industrial accident, military action, or terrorism. They can also be used for construction, military, mining, airports, and processing facilities.
A blast wall is typically erected to safeguard a building and its occupants when a temporary threat is identified, after construction of the building is complete. Blast walls are usually added to structures that didn't require and had no blast resistance before the threat was identified.
On the other hand, a blast-resistant building is specifically used for occupied buildings or buildings that contain high-cost or specialty equipment, in areas where hazards could reasonably (or even likely) be expected. The entire building is blast-resistant, rather than just protecting one side, or the facade, of the building.
To determine when a blast wall should be used, you must understand the type of hazards that could be present in the area it is placed. For example, in areas where the threat is seen as temporary, a blast wall might be enough to deflect shrapnel or simply protect the vulnerable structure of the building itself. In addition, blast walls can be combined to protect from multiple sides.
They are sometimes used in war or conflict zones, or as barriers during a planned explosion. In addition, military bases or airports might use them to protect aircraft or other expensive equipment. They can be used underground or underwater, and are used in multiple industries, many overlapping with industries that utilize blast-resistant buildings.
