‎ Reviewing Updated Coverage Results

 

Having changed the gas detectors to be of a toxic gas type, we can now look at the coverage results for the toxic analysis.

 

Click the Show Coverage Results button  from the toolbar to open the coverage results table. Here the values are displaying the results of the Main Gas Zone which has the Default Risk Grade applied which has a gas type set to toxic. The gas detectors in the project are also of a toxic type. If there were combustible gas detectors in the project, they would not be contributing to the coverage. Acoustic devices however do contribute to both toxic and combustible risk grades.

As the Visible Risk Grade was set to be for toxic mapping, the contours of the project will have been updated to reflect the coverage of the toxic gas detectors.

This concludes Tutorial 8. You should now have an understanding of how to change detectors to be of a toxic gas type.

 

Remember that to change the analysis to toxic you need to ensure three things:

  1. The detector's gas type is set to Toxic

  2. The visible risk grade has its Gas Type set to Toxic

  3. The zone or sub-zone used for the analysis has the "toxic" risk grade assigned to it.

     

When you have finished viewing the results close the project.
