(a) For each Extremely Hazardous Substance present over the Threshold Planning Quantity (TPO), create a Chemical in Inventory page (if a Chemical in Inventory page hasn't been created already) and enter the proper chemical name and Chemical Abstract Service (CAS) number (b) On each Chemical in Inventory page created for each Extremely Hazardous Substance present over the TPQ, enter in pounds (not range codes) the maximum quantity of each Extremely Hazardous Substance in the Max Daily Amount field of the Physical State and Quantity tab. (c) Enter the amount (in pounds) of each Extremely Hazardous Substance stored in the largest container or interconnected containers in the Max amount in largest container field of the Physical State and Quantity tab (this is the release amount used to determine the Vulnerable Zone). (it) Choose the appropriate description for the Type of storage container (drum, cylinder, tank etc.), storage pressure (ambient, greater than ambient etc.) and storage temperature (ambient, greater than ambient etc.) of each Extremely Hazardous Substance in those fields on the Location tab. (e) For each Extremely Hazardous Substance over TPQ, On the Physical State & Quantity tab check the appropriate boxes in the Physical State, Hazards and Health Effects fields (information on the above may be found by clicking on the Datasheet button which opens either the CAMEO Chemicals program or website.) 3. Vulnerability Analysis (CAMEOfm Scenario Page) (a) For each Extremely Hazardous Substance present over the Threshold Planning Quantity (TPQ), create a New Scenario page (if a Scenario page hasn't been created already) and enter the maximum amount in the largest container or interconnected containers in the Amount Released field of the Scenario Description tab, (b) On the Scenario page(s) Scenario Description tab, enter the concentration percentage in the Concentration field. (c) On the Scenario page(s) Scenario Description tab, enter the release duration in the Release Duration field as follows: (1) Gases-10minutes (2) Powders or solids in solution — 10 minutes (3) Liquids — No value shall be entered (d) Enter the proper natural physical state of the chemical at room temperature in the physical state field. (as specified in CAMEOfm- Chemicals) (a) On the Scenario page(s) Scenario Description tab, use the weather default settings or, enter average wind speed. Alternate scenarios may also be entered. (f) On the Scenario page(s) Scenario Description tab, rate the Risk, Consequences and Overall Risk of a release occurring at the facility on the bottom of the Scenario Page (the Risk Assessment should be based upon the Extremely Hazardous Substance, previous release history,. maintenance conditions etc.). 22 P208
