Frequently Asked Questions about Blast-Resistant Modular Buildings
What is a blast-resistant building?
Blast-resistant buildings are structures designed to withstand the effects of an explosion, such as those caused by bomb blasts or other high-energy events. These buildings are typically constructed using special materials and techniques that can help absorb, deflect, or disperse the energy from an explosion. Blast-resistant buildings are commonly used in areas that are at high risk for explosions, such as industrial areas, disaster preparedness, conflict zones and other critical infrastructure. They can also be used in industrial settings, such as chemical or oil refineries, where explosions or fires are a significant hazard. The goal of a blast-resistant building is to protect occupants and minimize damage in the event of an explosion, thereby increasing the safety and security of the building and its surroundings.
How are blast-resistant buildings rated?
Blast-resistant buildings are rated in two ways—the amount of pressure they can withstand from an explosion and the response level. The amount of pressure in pounds per square inch (psi) that the building can withstand is given a number rating. The higher the rating, the more resistant the building is to blasts. The American Society of Civil Engineers (ASCE) establishes response level ratings for blast-resistant buildings based on the predicted amount of repair that a structure would need after an explosion. The response level ratings are low, medium and high. With low meaning an explosion would do very little damage and require a low response and high meaning the building is predicted to sustain substantial damage in an explosion.
What is the blast response level mean for blast-resistant buildings?
Response levels are defined by the American Society of Civil Engineers (ASCE) as Low, Medium, and High. This correlates to the level of damage to expect to the building after a blast or explosion. A Medium Response Blast-Resistant Building will require significant repairs after a blast due to widespread building damage. The building should not be used until the repairs are made. A Low Response Level Blast-Resistant Building means the building may have little damage after an event, but can still be used. Minor repairs from damage may be needed but the building can be used in the meantime. When it comes to protecting personnel and equipment, HUNTER is the #1 name in safety for blast-resistant buildings (BRBs) in industrial areas, disaster preparedness and conflict zones. Individuals inside the buildings remain protected at each response level.
What is the difference between a blast-resistant building and blast-proof building?
Buildings can be engineered to withstand a great deal of pressure and force from an event, but explosions are powerful events. Blast-proof implies that there would be no damage after an event which would be nearly impossible. Because of this, blast-resistant is the term used industry-wide.
What is the PSI rating and response level of a blast-resistant building?
All Hunter Onsite buildings are API PR 752/753/756 compliant and feature a blast rating of 8 PSI, with a medium response level.
