Because the U.S. Department of Homeland Security (DHS) houses the Federal Emergency Management Agency (FEMA), the DHS is responsible for preparedness, response, and recovery to natural disasters as well as man-made events.

A CBR attack employs chemical, biological, or radiological (CBR) agents to strike a building or area.

The airflow patterns and dynamics in a building are of particular concern, specifically the heating, ventilating, and air conditioning (HVAC) systems of a building as an entry point and distribution system for hazardous contaminants, particularly CBR agents.

When sufficient questions or surprises arise from a building walk-through, an independent evaluation by a qualified HVAC professional is used to establish a useful baseline.

Poorly executed efforts and security measures to protect a building from a CBR attack can have adverse effects on a building’s indoor air quality.

Physical security measures such as locking the doors to mechanical rooms are low cost, but other physical security measures such as increased security personnel or packaged X-ray equipment are more costly.

Securing the outdoor-air intakes is a critical line of defense in limiting an external CBR attack on a building. Outside-air intakes must be located to allow for security.

When relocation of outdoor-air intakes is not feasible, intake extensions can be used to extend or enclose intakes in order to improve security without creating adverse effects on HVAC system performance.

Outside-air intakes have hoods sloped at 45° and a mesh screen that is used to prevent objects from being thrown into the intake.

Perimeter barriers such as iron fencing or other barriers that do not obscure visual detection of terrorist activities prevent public access to outdoor-air intake areas.

All outdoor-air intake buffer zones must be monitored by physical security, closed-circuit television (CCTV), security lighting, or intrusion-detection sensors.

Access to secure areas of a building must be strictly controlled by key locks, keycards, or key-coded doors with the access to keys, keycards, and key codes strictly maintained.

To prevent the widespread dispersion of a contaminant released within a building’s lobby, mailroom, or loading dock area, the HVAC system for these areas must be isolated.

Return-air grills must be inaccessible yet in an observable location, have increased security presence via more security personnel or security cameras, and have all furniture and visual obstructions removed from areas near return-air grills.

Many building automation systems have the capability to regulate airflow and pressures or shut down an HVAC system within a building in the event of an outdoor CBR emergency.

Manipulation of a building’s HVAC system could minimize the spread of a CBR agent. Building personnel must be trained to recognize a terrorist attack quickly and to know when to initiate certain control measures, such as maintaining pressure in stairwells, unless the stairwell is known to be the source of the CBR agent.

Particulate air filters used for biological and radiological particles are not effective for gases and vapors typically used in chemical attacks. Gases and vapors require adsorbent filters that contain activated carbon or another adsorbent-type medium.
