Knowledge Base of Physical Security and Process Safety Mitigation Measures and Products

Anti-ram bollards vehicle barriers

There are many safety or physical security products and approaches on the market today and differentiating between product offerings or mitigation measures can be challenging.  Commercial, government or industrial owners, designers and security professionals are often inundated with sales pitches from competing consultants and vendors; with few unbiased information resources to turn to for comparisons.  Stone Security Engineering has extensive experience in security and safety engineering, predicting and mitigating intentional or accidental hazards from explosions fires and toxics, security vulnerability assessments, training, and emergency response to structural collapse disasters. Stone’s engineers are well versed in blast and physical security mitigation measures and products; and is able to assist clients in comparing effective mitigation measures or product to provide them an optimized solution.

Security Design Analysis

Blast Resistant Design

Stone Security Engineering works with design teams to incorporate AT/FP, blast, progressive collapse, ballistic, forced entry and other security engineering requirements into overall project design.  As part of the design team we provide support and recommendations to the landscape architect, architect, and the structural and MEP engineers to incorporate required measures into the design.

As needed, we utilize military and other knowledge-based manuals for forced entry, ballistics and vehicle ramming and perform non-linear, dynamic analysis for blast resistant design.  We are experienced at addressing a full array of interior and exterior threat scenarios and analyzing and designing buildings to resist progressive collapse.

We are experienced in applying government criteria documents and manuals such as the PB-100, the Interagency Security Committee Security Design Criteria for New Federal Office Buildings and Major Modernization Projects, the DoD UFC 4-010-01 Minimum Antiterrorism Standards for Buildings, the  DoD UFC 3-340-02 Structures to Resist the Effects of Accidental Explosions, GSA Progressive Collapse Guidelines and the  DoD UFC 4-023-03 Design of Buildings to Resist Progressive Collapse (updated in July 2009).

Safety Design Analysis

safety design analysisStone Security Engineering works with ammunition manufacturing facilities, energetics laboratories, and similar installations that create, use, and store explosive and energetic material are required to meet explosives safety siting standards to protect personnel and limit hazardous effects in the event of an accidental detonation.

We are experienced in preparation of Quantity-Distance (Q-D) or risk-based Explosion Safety Site Plans according to DoD 6055-09M, DDESB guidelines, or similar industry standards for submittal for final approval. Stone’s engineers evaluate of potential explosion, fire, and fragmentation hazards onsite, develop feasible measures to reduce viable hazards, and implement these measures from conceptual through final design drawings to construction support. High fidelity modeling computational fluid dynamics and finite element analysis can be used to better define blast and fragment hazards, allowing for optimized solutions for facility owners.

Our team also has extensive experience in hazard assessment and mitigation of chemical, petroleum, pharmaceutical industries, and other types of plants that deal with chemical processing.  With this experience, we are able to provide optimized solutions to industrial clients to mitigate blast, fragment, fire and toxic hazards. We deliver industry-accepted modeling of gas dispersion, radiant heat, explosions, reactive chemical studies, and determination of potential toxic releases.

We work with companies in designing prevention, mitigation, and controls, to detect, shut-down and prevent the release of hazardous materials for compliance with Process Safety Management regulations and API, NFPA, CCPS and other related industry guidelines. The types of structures in industrial facilities we typically assess, retrofit or design include control rooms, containment for experimental or pilot-scale chemical processes, administration and office buildings, laboratories, and other permanent or temporary building types.


Blast Resistant master planning Considering counter-terrorism or process safety and hazard mitigation measures during the master planning  and project planning processes enables the project team to incorporate risk reduction from project inception; leading to more efficient, elegant, and cost-effective strategies and solutions. Stone Security Engineering works with project teams through the planning process, advising on site layout, building materials and massing, and building program layout. Work on these projects usually begins with a “Physical Security or Process Safety 101” class for team members to orient them to the implications related to their disciplines.


Blast Resistant Design TrainingWe believe in the adage that knowledge is power and are therefore devoted to sharing information and creating an informed consumer base. Stone Security Engineering presents security engineering, blast effects and design mitigation training classes for commercial, government or industrial owners, contractors, oversight agencies, vendors, engineering community and first responders. Classes can be customized to meet the goals and knowledge base of attendees and can vary from one-hour to multi-day sessions, depending on the curriculum.

Multi-threat Vulnerability Assessments

Blast Vulnerability Assessments and Blast Retrofit Design

Before owners and clients can develop effective risk-reduction programs, they must first quantify their current vulnerabilities. For our government and commercial clients, Stone Security Engineering perform s Multi-Threat Vulnerability Assessments against a wide variety of attack modes including Explosions (whether from VBIED or MBIEDs), Vehicle Ramming, Ballistics and Mob Attacks.

 Industrial Risk Assessments

Facility Siting AssessmentFor our industrial clients, Stone provides consequence-based or quantitative risk assessment of intentional or accidental release of blast, fire or toxic hazards and developed risk-based design or mitigation approaches that provide an optimized solution.

Working with the client we identify critical assets, potential attack modes and/or accidental release scenarios, and operational single points of failure. Once these parameters are developed, we perform analyses for the existing buildings and facility components and develop existing conditions assessments with recommendations for cost-effective ways to reduce the risk and increase safety, security and protection.

Criteria and Standards Development

Blast Resistant Facade Blast Resistant CurtainwallWe believe that there are no cookie-cutter solutions to protecting people and property from terrorist attacks or accidental releases of hazardous materials. Standards that are appropriate in the Financial District in New York City may not make sense for a building in a Midwest downtown area and standards developed for buildings built on military bases in the United States may not meet the needs of a compound in Kabul.

Design criteria for facilities and buildings exposed to terrorist attacks would differ from facilities and critical assets zoned in an industrial or petrochemical plant. Building on years of experience with a wide array of building and facility types, Stone Security Engineering works with clients to develop criteria and standards tailored to meet the risk reduction, safety, security, resiliency and protection needs of their organizations.

Security RFP and Solicitation Document Development

Security Design CriteriaEven when clients and owners have well-developed criteria and standards documents, the task of translating them into effective Requests for Proposal and project solicitation documents is rarely a straightforward process. Many counter-terrorism and physical security standards are written primarily by security personnel or are written very generally to cover multiple project types. Stone Security Engineering assists clients in incorporating general security documents into project specific Request for Proposal and project solicitation documents.
