Building Environmental Protection from Airborne
Chemical, Biological, or Radiological Attacks

BEAR engineers are experts in risk assessment and building environmental analysis. We can provide numerous services to assist you in protecting your building environment:

  • Building Environmental Protection. Inspect, evaluate and certify your building and facility per the National Institute of Safety and Heath's guidelines in NIOSH 2002-139 "Protecting Building Environments from Airborne Chemical, Biological or Radiological Attacks".
  • Air Handling System Permeability. Detect the time it takes external pollens (natural contaminants), pollution and/or terrorist agents to enter a building with BEAR's unique carbon detection based instrumentation and software models. HVAC-t modeling is also used to determine preventive measures.
  • Air Handling System Monitoring and Tracking. BEAR's unique modeling and simulation system allows facility managers to gauge, monitor and track contaminants and determine appropriate defenses in real time.
 
     
 

HVAC-t Software

 
  Here is an example of what the HVAC-t software program can do. The contour plots show concentration spread for a hypothetical situation in which Anthrax spores are released inside a science museum auditorium. Starting from the upper left, when t = 0, HVAC-t is able to predict how the airborne contaminants will move through the Heating Ventilation and Air Conditioning (HVAC) system in real-time. The HVAC-t System was developed by BEAR engineers to monitor data from smoke, chemical, and/or biological (viruses, bacterium) sensors. Uses for HVAC-t include, but are not limited to, management of chemical/biological threats, testing and brainstorming "what-if" scenarios, and for determining hazard mitigation strategies (e.g. hazard locations, evacuation routes HVAC circulation reroutes or shutdown, open and close events for specific doors and vents).
