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 [...]

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 [...]

Benefit of Scenario Coverage for Fire and Gas Mapping

By |2017-06-25T19:58:08+00:00September 19th, 2016|Edward M. Marszal, Effigy, Fire and Gas Systems|

More and more fire and gas professionals are asking about the benefit of using scenario coverage over geographic coverage.  They see that the amount of effort required to perform a scenario coverage mapping project is significantly increased so they desire to see evidence that the additional effort is worth it.  Well, it is worth the [...]

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 [...]

Gas Detector Scenario Coverage Using Gaussian Dispersion Models

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

In the past few years, the use of quantitative risk analysis tools to determine the required number of location of gas detectors has gotten more attention in the literature and also in real world project execution.  While there is great interest in these performance based methods, often referred to as fire and gas mapping, there [...]

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 [...]

It’s Easier Than you Think – A Simple Method for Selecting Fire and Gas Mapping Coverage Targets

By |2017-06-25T19:58:13+00:00December 9th, 2014|Author, Effigy, Fire and Gas Systems, Sean Cunningham|

Many fire and gas mapping practitioners are performing fire and gas mapping studies without first performing a hazard assessment to select the required coverage targets for the system.  This typically involves setting a “standard” target for coverage which is applied across all areas of the process plant.  While this is acceptable and will typically result [...]
