The first step in blast mitigation is to determine the potential threats. A thorough assessment is needed to define how and where explosive attacks can occur, as well as how much damage is expected. By establishing design basis threats, the building owner can then develop mitigation systems to minimize the impacts of a blast and allow emergency evacuation. The second step involves defining the threat landscape and how it might change during an attack. This information will help the project team devise a plan for the site.
The second step in blast mitigation involves the use of polyurea-based retrofits. These coatings can reduce wall deflection and blast-caused pressure by more than 50%. Because the material has high elongation, it can absorb pressure across a large surface area. The third step is minimization, which helps reduce the risk of objects near walls. The ultra-high strength barrier coating significantly improves the survival rate of occupants exposed to a blast event.
Another important step in blast mitigation is to understand the characteristics of different building materials. While new construction offers a variety of options for the design of blast protection, existing structures often require a custom solution. For example, some heritage buildings use dated construction methods and require more complex designs. Developing a cost-effective solution for a blast solution requires creative thinking. Furthermore, the use of temporary structures may introduce additional hazards such as flying debris.
In addition to building materials that are more brittle, there are other ways to increase the structural integrity of a building. For example, the use of polyurea coatings is an effective method of reducing wall deflection and lowering the blast-caused pressure. This type of coating is ideal for existing structures as it is flexible. Additionally, polyurea-based retrofits also reduce the risk of injuries, and may even save lives.
Polyurea Blast Mitigation coatings were the only material to pass bomb blast tests by the Air Force Research Laboratory. This type of coating was commercialised in the late eighties and has been widely used for bomb mitigation and ballistic protection in various locations. However, the chemical composition of polyurea is still unknown. But it is a proven material that is used for various buildings. The benefits of a polyurea coating on a building are incomparable.
Many types of materials are available. The best type is made up of an elastomeric polymer that is applied on walls and other structures. These materials are also used on columns, beams, and roof panels. By adding these coatings, the building can withstand blasts up to three times its original volume. A Blast is a powerful explosion, and the material used must absorb it. The impact of such a blast can cause serious injury to those nearby.
Several mitigation techniques have been developed to prevent the effects of a bomb blast. These include earthquake resistant retrofit methods, energy-absorbing materials, and other techniques. While most of these techniques are not yet proven, the research is necessary in order to identify the most promising ones. By implementing a blast mitigation strategy, the buildings can protect against a large-scale terrorist attack and be more secure. In addition to the use of protective coatings, many organizations are using the technology of 3M Safety and Security Window films to mitigate the impact of a bomb.
Whether you’re building a building for commercial or residential purposes, the right type of blast protection can protect both your people and your property. Fortunately, a number of companies now offer solutions to mitigate the effects of a bomb blast by installing protective window film on buildings. Similarly, the materials used in blast mitigation can be applied to buildings in many ways, including walls, columns, beams, and roof panels. A good solution will protect your building from a potentially devastating explosion and ensure that it stays in place for years.
The primary hazard in a blast is the primary fragments. These fragments can travel up to 200 feet per second. The pressure and noise caused by these fragments can damage a person’s eardrum and cause lung damage. Secondary fragments can also travel at high speeds. This is why a building should be designed with a blast mitigation system. If not, it will cause structural collapse and have to be rebuilt.
