Threat and Vulnerability Assessments
During the mitigation phase, the first step is to define the potential emergencies using a Threat and Vulnerability Assessment. Ideally, a facility would take an “all hazards” approach to this assessment, but sometimes the focus is limited to fire, security threats, or natural hazards individually.
JENSEN HUGHES conducts threat and vulnerability assessments to establish the design basis threats for a facility and the appropriate mitigation measures. Our engineers provide comprehensive reports that include prioritized mitigation solutions with associated costs to serve as a benchmark for the creation of a security master plan.
Our engineers have the capabilities to perform multiple engineering analyses that are aimed at quantifying the severity and risk of individual events and recommending mitigation measures to lessen the impact on life safety, and to the extent possible impacts on property and business continuity.
During the mitigation phase, our engineers perform various analyses including:
- Evacuation modeling provides the capability of predicting occupant response when subjected to different visual cues, such as way finding and signage, and physical barriers such as security gates and ticket kiosks, and smoke movement.
- We have extensive experience evaluating the impact of access restrictions (i.e. security barrios/checkpoints) as well as the impact of a wide range of events such as fires, bomb threats, and active shooter scenarios.
- A blast analysis is performed to assess resistance to direct pressure effects and progressive collapse. Our analysis tools range from simple engineering methods to more-complex analysis codes (e.g., LS-DYNA, ABAQUS).
- Our areas of expertise include detailed blast analysis, evaluation of facilities and buried utilities to blast effects, design of vehicle barriers and gates, missile impact, and design of blast and bullet-resistant facilities and enclosures.
- We help facility owners evaluate existing structures for the best available refuge areas (BARAs) utilizing guidance from FEMA for designating shelter areas for occupants.We perform a structural analysis identifying key design elements in buildings that provide the greatest amount of protection, and in some cases, we have designed cost-effective retrofit modifications to bolster the structural capacity of the building.
- We develop strategies for communicating proper severe weather protocol.
- Often facilities are insufficiently protected and the hazardous materials pose risks to life safety, property protection and business interruption. These risks can be minimized by properly characterizing hazards and providing adequate prevention and mitigation measures which can range from administrative controls to active fire and explosion suppression.
- We can assist facilities in each step of the process, including identification, documentation, analysis of the current level of protection, and design and implementation of supplemental protective measures.
- Enabling communication of the event to people so that they can safely evacuate is the end goal of a properly designed mass notification system.
- We are skilled at conducting the risk assessment required by NFPA 72, Chapter 24 to ensure that the mass notification system includes those components that are best suited to responding to the design basis threats established for the facility.
