How do I decide on the need for toxic gas detection?

By |2018-01-26T11:43:48+00:00August 10th, 2017|Effigy, Fire and Gas Systems, Kevin Mitchell, Safety Instrumented System|

We were recently asked about placing Hydrogen Sulfide (H2S) gas detectors in an area of the process where no H2S gas is normally present. Does the possibility for process upset conditions to abnormally result in the presence of toxic gas give rise to a requirement for detection? There was no way to simply answer the [...]

Do you really know the worst case for atmospheric dispersion of a gas release?

By |2018-01-26T11:43:59+00:00July 27th, 2017|Fire and Gas Systems, Kevin Mitchell, News|

Dispersion of an elevated release Often atmospheric dispersion models are needed to determine the potential for a gas release to impact workers or the public.  This is typically encountered during Fire & Gas Mapping.  There are quite a few decisions that go into a well-designed dispersion model, not the least of which are [...]

Benefit of Plume Fire Modeling over Point Models/Ray Tracing

By |2017-06-25T19:58:08+00:00October 5th, 2016|Author, Edward M. Marszal, Effigy, Fire and Gas Systems|

Most process plant engineering includes the development of 3D models that define the facility and help engineers to visualize the plant while it is still on the "drawing board", allowing for optimization of design.  These models are also a key part of determining the number of fire detectors that are required and where they should [...]

Sizing Graded Areas for FGS Mapping

By |2017-06-25T19:58:09+00:00August 30th, 2016|Author, Edward M. Marszal, Effigy, Fire and Gas Systems, News, Products, Services|

When performing fire and gas mapping utilizing geographic coverage techniques, one needs to define the extents of the area of concern.  This process allows the analyst to define the actual area that must be covered by the fire detectors or the gas detectors.  This is only important for geographic coverage methods because geographic methods do [...]

Fire Detector Viewing Distance Attenuation Factors

By |2017-06-25T19:58:09+00:00August 29th, 2016|Author, Edward M. Marszal, Effigy, Fire and Gas Systems, Products, Services|

The performance of optical fire detectors is generally defined by the test results that equipment vendors perform utilizing the FM 3260 test specification.  FM 3260 testing provides a set of results, that when graphically presented is often referred to as the "cone of vision" of the detector.  A typical cone of vision drawing for an [...]

Effigy Can Perform FGS Mapping in 2D, But Why?

By |2017-06-25T19:58:09+00:00August 19th, 2016|Author, Edward M. Marszal, Effigy, Fire and Gas Systems, News, Products, Services|

There have been times when customers have asked whether or not our Effigy fire and gas mapping software is capable of modeling in 2D instead of 3D.  The rationale for the request is that the customer does not have 3D models for their facility, but would still like to have an analysis performed.  All of the [...]
