About RBI 581 ISO-Risk Plot Preferences

The RBI 581 ISO-Risk Plot Preferences workspace allows you to modify the default values of the following parameters that are used in the RBI 581 ISO Risk Plot.

The values that you enter must satisfy the following conditions:

All values must be numeric.
All values must be greater than 0 because the graph is plotted on a logarithmic scale.
The lower limits must be less than the upper limits.
The upper limits for each risk level must be in ascending order. For example, the upper limit for the Low risk level must be less than the upper limit for the Medium risk level.

Note: The units of measure can vary depending on the UOM Conversion Set that you use. For example, if you use the Metric conversion set, the Consequence of Failure will be measured in square meters instead of square feet.

RBI 581 ISO-Risk Plot Maximum Probability (Events/Year)	The upper limit for the Probability of Failure values that are plotted on the vertical axis of the SHE Risk graph.	0.306
RBI 581 ISO-Risk Plot Minimum Consequence (Square Feet)	The lower limit for the Consequence of Failure values that are plotted on the horizontal axis of the SHE Risk graph.	10
RBI 581 ISO-Risk Plot Maximum Consequence (Square Feet)	The upper limit for the Consequence of Failure values that are plotted on the horizontal axis of the SHE Risk graph.	1000000
RBI 581 ISO-Risk Plot Low Category Limit (Square Feet Per Year)	The upper limit for the risk level, Low.	0.1
RBI 581 ISO-Risk Plot Medium Category Limit (Square Feet Per Year)	The upper limit for the risk level, Medium.	10

RBI 581 ISO-Risk Plot Maximum Consequence (United States Dollar)	The upper limit for the Consequence of Failure values that are plotted on the horizontal axis of the Financial Risk graph.	100000000
RBI 581 ISO-Risk Plot Low Category Limit (USD/Year)	The upper limit for the risk level, Low.	10
RBI 581 ISO-Risk Plot Medium Category Limit (USD/Year)	The upper limit for the risk level, Medium.	1000
RBI 581 ISO-Risk Plot Medium-High Category Limit (USD/Year)	The upper limit for the risk level, Medium High. If a data point contains a value higher than this limit, the risk level is High.	100000
