90 CAPTool User Guide Step 4: Inventory of High-Consequence Assets/Asset Classes Introduction Step 4 combines results from Steps 2 and 3 to identify the assets and asset classes that exceed one or more consequence thresholds. This is the first opportunity the user has to view the assets deemed of high consequence. CAPTool arrays the assets (in columns) against the hazards and threats (in rows) to which they are vulnerable. Purpose The primary purpose of this step is to identify assets or asset classes that exceed consequence thresholds. A secondary purpose is to present the systemwide high-consequence assets arrayed against the hazards/threats to which they are vulnerable. Definitions Asset Classes--Those used in this step are a reduced set from Step 2, having been screened based on the postulated hazards and threats of concern. Proper Name Assets--Specific assets that have special characteristics and are not part of a larger asset class. These typically involve large and well-known bridges, buildings, and stations. Systemwide--The assets/asset classes collected from among the full range of those of concern to transportation agencies. Assumptions 1. The CAPTA methodology determines potential consequences as a function of asset charac- teristics regardless of the hazard or threat that leads to the losses. 2. Default values are based on the nature of the assets and their typical function as they relate to missions or functions, potential occupancy, physical characteristics, and public perception. 3. All default values are within a range consistent with the purposes of this process. 4. Consequences are event-neutral; that is, focus is on assets that could conceivably be at risk rather than the specific hazards and threats that put them at risk. 5. The user has the ability to select any named asset for further consideration. This selection may be based on attributes not considered in the CAPTA methodology. User Inputs No additional inputs are required from the user in this step. This step produces results based on default values unless the user overrides them. Output The result of this step is a list of assets with the potential for consequences that exceed the selected consequence threshold given the hazards and threats considered (Figure 9.) Using the assets and asset classes of concern, the user then proceeds to select measures to consider for mit- igating consequences. ATA Example In the ATA example in Figure 10, the road bridge, road tunnel, and some administrative and support assets are shown compared against the relevant hazards/threats to which they are exposed that result in consequences that exceed the thresholds set by the user.
