The concentration graphs only ever show the outdoor concentration, but if you move to the Toxic tab section you will see that the Probit, Lethality and Dose graphs display separate results for indoor and outdoor effects, and that there are separate Footprint graphs for outdoor and indoor effects.

The Lethality graph shows that the greatest downwind effect distance is for the F 1.5 m/s weather outdoors, with a distance of about 2.5 km to a lethality level of 10%. The indoor effects for this weather reach about 2.25 km to 10% lethality. The shortest downwind effect distances are for D 5 m/s indoors, which reaches about 1 km for a lethality level of 10%.

Viewing outdoor toxic lethality results against the map

Select the Catastrophic Rupture Scenario in the Study Tree, and then click on the GIS button in the Home tab of the Ribbon Bar. A Results Selection dialog will appear, as when you view Graphs. Make sure that all of the Weathers are in the Selected items list, and click on Finish to proceed.

After a pause a GIS Results View will open, appearing as a separate tab in the Document View area. GIS Results Views display effect results on the GIS, i.e. against the background of the map.

By default, GIS Results Views display the Cloud Footprint results, but the Event field in the Consequence tab of the Ribbon Bar lists all of the types of effects that are available for the Scenarios and Weathers included in the current GIS View, and you use this list to view a different type of effect. For this tutorial, select Toxic Outdoor Lethality Footprint, as shown.

If a Graphs View or GIS Results View is displaying results for a single Scenario and Weather, it will display results for more than one effect level when it first opens (e.g. it will have separate contours for 0.1%, 1% and 10% lethality). However, if it is displaying results for multiple Scenarios or Weathers, it will display results for a single effect level when it first opens. The effect levels of interest are defined in the Toxic Parameters tab of an Equipment item and a Scenario.

By default the effect level displayed for multiple Scenarios or Weathers will be the lowest effect level of interest defined for the Scenarios, which is 0.1% lethality for toxic effects by default. To view the lethality contours for a different level, click on the Edit Settings button in the Consequence tab of the Ribbon Bar to open the Edit Settings dialog. Move to the Toxic Parameters tab, and enter a value of 0.1 in the Lethality Levels table, pressing [Enter] after you have typed the value in order to commit the change.

When you click on OK to close the dialog, there will be a pause and the GIS Results View will then display the results for a 10% lethality level, as shown. The effect contours for all Weathers are able to reach populated areas, though only the 1.5 m/s Weathers are able to reach the town and the village.

Note: the Edit Settings dialog also allows you to change the number of effect levels to display. By default this is initially set for one to multiple Scenarios or Weathers, but you can change this in the dialog.
