Multi-hazard defense

Safeguard site personnel with FORTRESS Protective Buildings.

Leveraging BakerRisk’s decades of R&D, the investigation of hundreds of incidents, and 40+ years of assisting clients in personnel protection, BakerRisk developed the FORTRESS Protective Buildings – a Multi-Hazard Resistant Building (MRB) – to provide the optimal solution to protect workers and critical assets from hazards that may be present at industrial facilities handling flammable, toxic, explosive, or energetic materials.

Blast

BakerRisk conducted two series of blast tests for FORTRESS Protective Buildings using the Shock Tube Test Rig at their Wilfred E. Baker Test Facility.  The first series of tests was on the joint between two concrete modules and included the panel joint, corner joint, and reaction frame. The second series was on the FORTRESS blast, fire, and smoke resistant door mounted in a FORTRESS concrete panel. Both series of tests were conducted using a 10’ x 10’ target area in the shock tube.

The concrete panel was tested five times and remains in our specimen yard today, demonstrating the true resilience of FORTRESS!  Results indicated negligible vulnerability at design basis blast loads.

  • Design Basis Free-field Loads (Test #1): 11.3 psi at 1,006 psi.ms resulted in a max displacement of 0.5-inches (hairline cracks)
  • Design Basis Reflected Loads (Test #5): 20.9 psi at 1,639 psi.ms resulted in a max displacement of <1.25-inches (cracking)

Fragment

BakerRisk conducted projectile testing of a representative FORTRESS wall panel in the High-Pressure Test Rig at the Wilfred E. Baker Test Facility. These tests, which were conducted using a gas gun developed by BakerRisk for fragment throw, confirmed that FORTRESS’s 8-inch reinforced concrete design provides protection from fragment throw equivalent to ¾” thick steel!

Fire

Thermal radiation testing of the concrete panel at the joint seal between modules was conducted using impinged jet fire in the Process Safety Test Rig at BakerRisk’s Wilfred E. Baker Test Facility.

  • ¼-inch saturated propane jet fire for 1-hour for the panel and 30-minutes for the door.
  • Full height panel with thermal barrier in panel joint.
  • Results indicated negligible vulnerability for design basis thermal exposure.
  • Resistant to temperature rise as well as smoke and toxic combustion off-gases.
  • Temperature in the enclosed volume behind the panel remained below 110°F, well below ASTM E119 required 139°F.

Toxic

BakerRisk has developed FORTRESS to resist gas infiltration in an emergency, and it includes an additional inner room that is even more leak tight for use as a Shelter-In-Place (SIP).

FORTRESS has inherent gas ingress protection due to the limited gaps in the design of the building shell as well as the vestibules at building entrances/exits.  Additional safety features for prevention of gas ingress results in an air exchange rate (measured in ACH) between the FORTRESS building and the outside of <0.08ACH, which drops to <0.026ACH for an interior SIP room.

Extreme Weather

Every worksite must account for staff protection during an emergency or natural disaster. Protecting workers is of chief importance during hazards associated with natural disasters as well as potential knock-on effects associated with blast, fire, or other possible operational impacts during a naturally occurring event.

Planning and safety drills only get you so far. Investing in a disaster-resilient FORTRESS is one of the best ways to ensure that your employees are protected during unexpected events.

Hazard containment solutions

Get the protection you need with SAFE™.

We have developed our Shock and Fragment Enclosure (SAFE™) to provide clients with an efficient and reliable solution to safely conduct hazardous tests. SAFE™ designs address potential hazards from hydrostatic and pneumatic pressure, battery abuse testing, rotating equipment, explosives, and hydrogen generation and storage. Each SAFE ™ is completely customizable based on the specific size and hazard requirements. SAFE ™ provides a single point of contact for design, construction, and installation of testing enclosures.

Use Cases

What a SAFE™ offers your facility.

Pressure testing

Following guidance from ASME PCC-2 and HSE GS4, barricades or enclosures may be required when the risk from projectiles or blast loads is high. SAFE™ provides protection from high-velocity projectiles, blast loads, and liquid jetting from the pressure testing of equipment.

Battery abuse testing

SAFE™ provides protection from potential fires and explosions that may occur during abuse testing of lithium-ion batteries. Industries served include automotive, battery manufacturers, and BESS.

Rotating equipment

SAFE™ provides protection from high-speed blade projectiles that may occur during the testing of rotating equipment. Industries served include manufacturing, heavy industry, and engine manufacturing.

explosion

Explosive storage

SAFE ™ provides protection from explosion hazards associated with the handling or storage of explosives. Industries served include military, space, and explosive manufacturing.

RIGID structural solutions

Metal Buildings

RIGID blast resistant pre-engineered metal buildings.

BakerRisk has teamed with Rigid Global Buildings (Rigid) for the design, manufacturing, and delivery of blast resistant pre-engineered metal buildings (PEMBs). Blast resistant PEMBs provide an economical solution to address design requirements for buildings ranging from Control Rooms, Laboratories, Maintenance Buildings, and Fire Water Pumphouses.

Details

The functions and benefits of a PEMB.

Economic

The blast resistant PEMB is designed specifically for the blast load hazard and the building size. Coupling the customized blast resistant design with a proven economical construction method results in a cost-effective solution to meet design requirements.

Function and Appearance

PEMBs have been designed to serve multiple functions ranging from multi-story lunchrooms to maintenance buildings with 100-foot clear spans. PEMB construction also provides the opportunity to incorporate distinctive exterior finishes, blast resistant windows, and other features to make your building stand out.

Blast Loads

Blast resistant PEMBs can be designed to resist moderate blast loads typical of chemical processing facilities. By customizing the design of structural elements, higher blast loads can be resisted while still providing the level of protection required.

Proven Partner

BakerRisk has partnered with Rigid Global Buildings, a leader in the PEMB industry, to deliver blast resistant metal buildings. Through our partnership, BakerRisk-designed PEMBs can be delivered to project sites across all of North America.
