What Is a Blast Wall?

A blast wall is a barrier that protects structures and lives from explosive blast pressure, debris and fires. Blast walls prevent fragmentation and flyrock from traveling at high velocity and reduce peak explosive pressure from shockwaves that can impact the surroundings.

Blast walls can be made out of different materials such as steel or rubber, in some cases as permanent structures from reinforced concrete. The most effective and longest-lasting investments for commercial blast control and protection use only premier materials and designs.

When to Use a Blast Wall

Blast shield walls are erected to prepare a site for detonations. These barriers absorb the energy created by an explosion and block shrapnel and debris from causing unintended damage or loss. Beyond their uses for controlled blasts, a blast wall can safeguard workers, pedestrians and infrastructure in the event of an accident, like an industrial boiler explosion or a terrorist attack.

Blasting operations are highly regulated and often required for projects and processes that produce explosions. The use of a blast wall may be necessary by local and environmental codes to minimize danger and noise to people, the landscape and the ecosystem. Civil defense structures, ammunition manufacturers and other sites where safety is critical may incorporate blast walls into their facilitys’ designs to guard against catastrophe.

How Blast Walls Are Utilized

Blast walls are often set at 90-degree angles to surround a blast or shield a facade. They can cover detonations underground or underwater as well. They can also be positioned overhead or on roofing systems, both internally and externally.

Below are some additional common applications of blast walls:

  • Construction or mining operations erect blast walls before breaking and removing obstructive rock. 
  • Blast walls are positioned at pedestrian entry control points, like parking garages and airport terminals, to shield vulnerable facilities from blast fragmentation and blazes.
  • Facility managers can retrofit older buildings with blast walls to withstand heavy explosive forces and enhance safety.
  • The risk of chemical explosions and consequent injuries and damage, particularly at petrochemical manufacturing plants and research labs, can be mitigated with blast walls.

Why Set up a Blast Wall?

Even during controlled explosions, countless variables exist that pose life-threatening conditions at your work site or facility. While personnel can avoid blasting areas, blast walls lower the risk to other structures like nearby homes or adjacent rooms. A blast wall is an investment that limits liabilities, ensures compliance and grants peace of mind, benefitting all stakeholders in a project.
