Blast Mitigation

Definition - What does Blast Mitigation mean?

This is a strategic plan or system designed to reduce the aftermath effects of a blast, which are caused by energy forces and pressure impulses. It is used to prevent the flying of glass particles, debris and collapsing of structures as a result of an explosion. As much as it protects people, assets and buildings, it acts as a corrosion management tool through surface modification.

Corrosionpedia explains Blast Mitigation

During a blast, fragments, sound, shock waves and other forms of energy are released into the atmosphere. These effects cannot be stopped but the intensity can be reduced so as to reduce the number of casualties and injuries.

The preparation is characterized by evaluating, assessing and testing the systems. In glass, the mitigation is achieved by products that do not shutter but crumble upon impact. Reinforcements such as anchor systems are used to hold structure components into the walls so that they do not collapse.

The effectiveness of the systems are proved before use by open air or enclosed (shock tube) test methods that include explosives. This means that reinforcements, composite materials, sandwich material and metals like steel are used to ensure that most of the energy is absorbed or reflected.

A blast mitigation capability is achieved when all elements or composition of an explosion and hazards are known. When coating is involved, the system caters for corrosion management. The glazing industry is deeply into this concept to ensure that fragmentation does not occur.
