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 [...]

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 [...]

Another Limitation to Extending Test Intervals

By |2016-08-11T12:48:36+00:00August 11th, 2016|Author, Edward M. Marszal, News, Safety Instrumented System, Services|

A customer noted that some operating companies limit the extension of their test intervals so that the test interval is at least half of the expected demand rate.  For instance, if a safety instrumented function (SIF) is intended to prevent against a hazard whose initiating event rate is once in ten years, then the test interval [...]

Advances in Design of Gas Detection Systems

By |2017-06-25T19:58:12+00:00August 21st, 2015|Author, Kevin Mitchell, News|

Designers of fire and gas systems have long struggled with the question of how many detectors are required and where those detectors should be located.  Historically, decisions about the number and location of detectors were made based on heuristics, expert judgement, or rule-of-thumb.   The first step forward in gas detector placement came in 1992 with [...]
