Tutorial 8 - Toxic Gas Detectors

 

Toxic gas detectors are commonly placed near accommodation areas and region with high volumes of personnel and are used to detect varying toxic gases (e.g. H₂S, CO, CO₂, HF, etc).

 

In Detect3D, the geographic method is used for toxic gas detectors, however it is recommended to look at ventilation and dispersion modeling results to better determine re-circulation regions and areas toxic gas could exist from a gas leak to best determine detector placement.

 

Toxic gas detectors in Detect3D can be either of point type or open-path. Users may add a new gas detector with a toxic type or change an existing detector.

 

This tutorial will go over how to edit an existing risk zone to account for toxic gas mapping as well as adding a new detector with a type set to toxic gas.

 

Learning objects for this tutorial include how to:

• Edit a risk grade to be for toxic gas detectors

• Add a toxic detector

• Changing the risk grade assigned to a zone
