TIC/TIM Assessments of U.S. Air Force Bases

TIC/TIM

Challenge

Terrorist tactics are known to include use of explosives as well as toxic industrial materials (TIMs) and toxic industrial chemicals (TICs).  Facilities at U.S. Air Force Bases could be exposed to TIC/TIMs from an attack directed at other facilities in the area, from a direct attack, or from TIC/TIMs being transported on nearby highways, railways, and waterways.  Accidental release of these materials can pose significant risks if the accident is within a specified proximity to the base and the concentration levels are above a predetermined level.

Solution

ARA personnel met with critical personnel at both bases to assess the physical layout, critical utilities and infrastructure, TIC/TIM on base, current threats, emergency management procedures, and MOU’s in place.  To establish potential TIC/TIMs inventories and threats external to the base, ARA interviewed Local Emergency Planning Committee (LEPC) representatives, local fire and police departments and reviewed Tier II data from surrounding businesses/industries.  Based on these meetings, ARA developed a reduced list of potential TIC/TIM threats internal and external to the base and employed the Facility Security Risk Management methodology to determine the threats posing the highest risks. Four scenarios were selected for further modeling with the software tool, Hazard Prediction and Assessment Capability (HPAC), which displays a plume model with potential agent dispersal and concentrations overlaid on base maps.

Impact

The results identified potential vulnerabilities and the assessment team provided recommendations to address these vulnerabilities.
