Protective Building Design Elements

Logo ElementModule X Solutions designs and manufactures blast resistant buildings in petrochemical facilities with safety and protection as the guideline for our protective building systems.


  • ASCE 2010 2ND Edition Design of Blast Resistant Buildings In Petrochemical Facilities
  • API RP-752/753
  • NFPA 496 – Electrical Classification
  • NFPA 70 – NEC
  • IBC 2012

The fundamental blast design parameters:

1.Blast Over Pressure (*measured in psi-pounds per square inch)

  • Free Field Over Pressure is the increase in ambient air pressure due to a blast event.
  • Free Field Over Pressure is measured in open space.
  • This means that an 8 psi free field overpressure blast event will increase the ambient air pressure, which is about 14.7 psi, to 22.7 psi.  This increase is instantaneous and devastating.

2.Blast Duration

  • The time from initial change in pressure to return to ambient pressure.
  • Positive phase is the build-up of pressure to the elevated level.
  • Negative phase is the return from the elevated pressure back to the local pressure.


ASCE provides for three damage responses for practical blast engineering:

  • Low
  • Medium
  • High

*MXS’s standard blast resistant module designs are engineered with safety at the forefront.

Our over engineered structures provide a higher/stronger threat resistance over our competition in order to ensure the safety of the habitants and minimize potential liability that could arise due to unforeseen anomalies, calculations, and/or design requirements.

Additionally, our team ensures that the building(s) designs and solutions, are TDLR compliant by incorporating these design criteria requirements. MXS’s structurally superior protective building line sets us apart in the industry and is designed to combat vapor cloud explosions, which are common threats in petrochemical facilities. Our modular solutions provide the highest levels of protection and security for personnel and equipment, with a range of designs and layouts which consist of single, multi-module interconnecting, and large clear span units.

The quality and customer service experience associated with our solutions create a unique product offering that is the finest in the industry. Our clients are the recipients of highly and properly engineered solutions supported by a dedicated and experienced team. Constantly focused on product integrity and continuous improvement, MXS’s top priority is to provide our clients with solutions that protect their most important assets.

MXS can provide standard or specialized/customizable products in order to fit your requirements. Blast resistant or non-blast resistant all welded designs are available. Solutions can be built per specifications and our team members are willing and excited to assist in the design, specification creation and/or qualification process. We have partnered with many customers on specialized building projects and because of our extensive design, engineering and manufacturing capabilities we can provide and incorporate any number of options into your project.

Competitive Advantages of an Module X Blast Building

Mechanical Fastening System

Improving the flexibility and installation of blast resistant buildings in petrochemical facilities

Module X Solutions utilizes proprietary building technology to increase overall customer value by an improved design of blast resistant buildings. The patented mechanical fastening system we incorporate into our product line, streamlines and drastically reduces the installation process for blast resistant modular buildings.

The traditional method of installing these buildings involves a more expensive and time consuming welding process. This proprietary solution allows our customers to have more flexibility, while controlling field installation costs, reducing site insurance liability, and increased speed of deployment of a fully integrated engineered solution.

The mechanical fastening system benefits:

  • Significant reduction in deployment time, resulting in lower installation costs
  • Faster occupancy with less site disruptions
  • No hot work permits or painting required
  • Flexibility to relocate complexes and to scale buildings for future reconfigurations and/or addition
  • Engineered to provide the same blast protection as a welded building

When compared to the traditional welded method of installing a 24’ x 40’ complex, mechanical fastening offers approximately a 7 to 1 reduction ratio in installation time. Therefore, in less than the time it takes to weld the interior and exterior seams, a building with our mechanical fastening system can be completely installed and occupied.

X-GAP (Deformation Barrier)

Our proprietary X-Gap Deformation Barrier engineered solution is the safest and most protective design in the marketplace. With the X-Gap, our clients receive an added level of safety for occupants and/or equipment inside of the structure. The X-Gap prevents equipment, furniture, and other objects inside the modular building from becoming projectiles during a blast event.

“Protecting you against the secondary effects of a blast.”

Projectile Engineering

Many blast resistant building providers do not provide complete protection from an explosion; they simply provide protection from the blast overpressures. It is vital that consumers understand that blast engineering does not consider projectiles or flying debris, it only incorporates the effects of blast overpressures.

Module X Solutions has a standard for projectiles that can be applied to any building we manufacture. Additionally, we can provide new projectile engineering for any unique design requirements.
