Blast Resistant Partitions: Key to Fire & Blast Protection in High-Risk Areas

In high-risk industrial and defense environments, explosion resistors serve as a significant obstacle to protect personnel, equipment and structural integrity against the harmful effects of explosions. These partitions are engineers with rigid standards similar to the blast resistant doors and are a major element in the internal space division and control in the explosion-prone areas.

Similarly, to blast resistant doors, blast resistant partitions design shall be selected depending on:

  • Blast Duration – Peak time and duration of the blast.
  • Height of partition.
  • Vertical member spacing.
  • Blast load or pressure.
  • Blast on one side of the portion on both sides of the partition.
  • Frame – Structure Steel.
  • Partition Wall – Durasteel/Promatect
  • Board - 9.5mm thick
  • Finish – Standard shop applied zinc base primer, ready for site painting.

Design Considerations

The design of an explosion resistant division must be carefully corresponding to specific site conditions and blast dynamics. Major parameters affecting the selection and configuration include:

  • Blast Period: The total duration of the peak overflow and blast phenomenon determines the structural requirements of the partition system.

  • Height Of Partition: longer partition requires increased vertical reinforcement to ensure stability under pressure load.

  • Vertical Member Spacing: Appropriate vacancy of members of vertical steel is important to distribute the blast forces equally and prevent structural failure.

  • Blast Load or Pressure: The design is guided by the expected overpress rating - resistance to peak blast pressures, usually defined in the bar or PSI.

  • Blast Direction: Whether the explosion is expected to affect one side or both sides of the partition affect the choice and structural symmetry of the material.

Construction Details

  • Frame: Heavy-duty structural steel frames form backbones of the division system, providing strong support and load transfer under the blast impact.

  • Partition Wall Panels: special high-demonstration boards such as Durasteel or Promatect cladded, are known for low deformation under their fire resistance, mechanical strength and stress.

  • Board Thickness: Panels typically use 9.5mm thick boards, though this may vary based on the blast rating and specification requirements.

  • Finish: All steel components are treated with a shop-applied zinc-based primer, providing corrosion resistance and a ready-to-paint surface for on-site finishing.

Modular and Customizable
At SomNandi Industries, we provide modular blast protection for buildings with systems that can be tailored to the layout, height, and risk level of your facility. Whether integrated into a new build or retrofitted into existing infrastructure, our solutions are engineered for maximum security and adaptability.

Integrated Fire And Explosion Protection
To provide dual-layer protection, the explosion division of SomNandi offers high-security partitions that can also be rated for fire resistance, making them ideal for environments where post-light fire risk is a concern. These joint explosion and fire-rated systems ensure the safety of personnel, the continuity of operations, and operational efficiency under extreme conditions.

Explosion Resistant Partitions Application

Blast resistant partitions are necessary in separating functional areas within a dangerous environment. General applications include:

  • Control room and operator cabin within petrochemical plants.

  • Laboratories and testing chambers in defense and aerospace sectors.

  • Compressor, transformer or boiler room in power plants and utility stations.

  • Storage facilities for risky materials.

  • Military bunker and ammunition storage area.

  • Safe access area in high-protection installations.
