Successfully Blast-Tested Blast-Resistant Buildings

The Importance of Blast Testing

Whether you choose to get your blast-resistant modules from us or one of our competitors, we want to do whatever we can to help you save lives. With that in mind, we have compiled all of the information you need to make the safest decision possible. From what to look for in a manufacturer and key product attributes to demystifying complex industry terminology, you’ll find it all right here.

Engineered to our industry-leading safety specifications, each of RedGuard Specialist Services blast-resistant modules adheres to the requirements of API RP 753 and API RP 752 and applies a proven, successfully blast tested design.

Blast Testing

At RedGuard Specialist Services, we can never overstate the importance of blast testing. If the manufacturer you are considering has not performed a successful live field blast test, we strongly recommend you look elsewhere.

Our successful blast tests were conducted by detonating an explosive charge a set distance from the building being tested. The entire process was filmed by a high-speed camera and afterward, the footage, as well as the building’s interior, exterior and structure, were closely examined to determine any damage. In addition, measurements were taken to see how much the entire building shifted during the test.

The importance of blast-pressure ratings

While blast pressure is a key component of a blast-resistant building’s design formula, it is the combination of that pressure and duration and response-level that tell the full story of how a blast-resistant building will hold up to an explosion.

Understanding response levels

Understanding response levels is a critical component in selecting the right blast-resistant modular building, unfortunately it can also be somewhat misleading. While it’s natural to assume that a building given a “high response” rating would stand up well to a blast and offer a high level of protection, in reality the opposite is true. When comparing blast-resistant modules, it is generally a good idea to always replace “response level” with “damage level.”

Below is how the American Society of Civil Engineers (ASCE) defines each response level:


Low Response

Localised component damage. Building can be used, however repairs are required to restore the integrity of the structural envelope. Total cost of repairs is moderate.



Medium Response

Widespread component damage. Building should not be occupied until repaired. Total cost of repairs is significant.


High Response

Key components may have lost structural integrity and building could collapse due to the environmental conditions (i.e. wind, snow, rain). Building should not be occupied. Total cost of repairs approaches replacement cost of building.

Industry Regulations

Unfortunately, the overall category of blast-resistant modules is so new that there is not—as of yet—an official regulatory board. Before choosing a blast-resistant building for your operation, it is extremely important to take a close look at its overall response (damage) rating, how well it performed in controlled blast tests and its manufacture’s adherence to the practices recommended by the American Petroleum Institute (API) in RP 752/753 and third party approval of blast designs.
