Blast Analysis and Explosive Hazards
The ability to realistically assess blast-related hazards and provide effective mitigation strategies is crucial to a broad range of industries including, government entities, land use planning and oil, gas and chemical and manufacturing facilities.
At 小蝌蚪视频, we have a global team of dedicated specialists who use advanced simulation tools to model the dynamic response of structures and equipment to blast overpressure, fragment impact and blast-generated debris. No matter the cause of the explosion, our experts can work to understand the realistic risk consequences and support your organization in finding the most effective mitigation strategies to suit its needs. We perform blast testing services to validate modeling methods or proof-test protective structures, windows and doors with our Shock Tube Testing facility based in San Antonio, TX.
Blast Mitigation Analysis and Design Services
We provide a range of services to support organizations in understanding the impacts of blast loading on structures and work collaboratively with clients to produce mitigation measures to help protect their facilities and personnel against blast-related hazards.
Understanding Catastrophic Risk
Beirut Explosion Podcast and Infographic
How have major industrial incidents, transportation accidents, terrorist attacks and natural disasters changed our understanding of risk? On this episode of our Risk Matters X.0 podcast, understand more about what we can learn from catastrophic incidents to improve awareness and better manage risks.
Our Capabilities
Protective Design
Using the built environment to protect your organization against both man-made and natural hazards is a crucial step in managing your risk. Our team of protective design engineers helps clients to understand vulnerabilities to buildings and other critical infrastructure for a range of hazards and how to implement rational cost-effective mitigation strategies.
Featured Services:
- Recommendations on implementation of physical hardening measures (perimeter protection, blast analysis and design, façade strengthening, disproportionate collapse mitigation, local hardening of security command centers and other critical areas)
- Security systems evaluation and design (intrusion detection, monitoring and surveillance, access control systems, security policies and procedures, redundancy evaluations, etc.)
- Evaluation of all hazards mitigation to include Natural Hazard analysis, design and construction management activities (seismic retrofit of buildings and structures, equipment bracing and anchoring)
- Dependency mitigation actions (emergency backup power, spare parts and supplies, cross-training of personnel, emergency response plan, business continuity plan, etc.)
- Finite Element Modeling

Fragment Analysis
In the event of an explosion, fragment analysis can be used to predict fragment velocity and fragment damage/penetration to a target. After the initial velocity is determined, using empirical evidence and theoretical calculations, trajectory calculations determine the potential velocity and range at impact. Finally, penetration calculations can help determine the vulnerability of structures and equipment.
Our Approach
- Primary Fragments and Shrapnel from Munitions and Laboratory / Production Equipment
- TP-13 Analysis for Building Debris Throw
- Design of Barricades to Prevent Perforation by Hazardous Debris and Protect Personnel

Shelter-In-Place and Evacuation Assessments
Emergency response planning may direct personnel in some buildings to shelter-in-place (SIP) during a toxic/flammable release. To qualify candidate buildings as shelter-in-place, it is crucial that you perform sufficient modeling and testing to fully understand the baseline risk. 小蝌蚪视频 uses the following three (3) stage approach to provide our clients the answers to these questions:
- Perform gas dispersion modeling to determine the toxic/flammable environment outside the building
- Assess the leakiness of the building through testing to identify major leakage sources
- Perform infiltration calculations to determine the duration the building can be used to SIP
