Free Introductory Class: Fire & Gas Mapping, December 9, 2020 – Westech


KenexisCourse

This free introductory class will offer a special emphasis on Liquefied Petroleum Gas (LPG)

In this training we will cover:

  • The event that created the need for special focus
  • How we got here and what to do next regarding fire and gas systems
  • The difference in geographical and scenario coverage and when to use each
  • How scenarios like gas leaks are modeled
  • The differences in ray tracing and finite volume analysis
  • Why modeling a fire plume appropriately is so important
  • How to manage a project in Effigy to perform both geographical and scenario-based assessments of coverage

09 December – Intro Class on Fire & Gas Mapping – LPG Emphasis

4-hour introduction class starts at 9:00am (New York City time) with special emphasis on LPG including both flammable gas scenario-based project and fire geographic-based project demonstration focused on ISA TR84.00.07. CEU certificate is issued for completing training.

Fire & Gas Mapping Overview

Kenexis is a pioneer in the performance-based placement of fire detectors and gas detectors in the process industries, starting with our strong involvement of the ISA technical reports, premier technical safety consulting services, and best-in-class fire and gas mapping software – Effigy. Beyond our work with the standards committee, we have also developed the premier training course on fire and gas mapping, which is distributed through ISA as EC56P – Fire & Gas System Engineering – Performance-Based Methods for Process Facilities. We are also the authors of the only book available on fire and gas mapping, Performance-Based Fire and Gas Engineering Handbook (also published through ISA).

The process of determining the proper location and number of gas detectors is conceptually simple, but in application requires a lot of detailed work to be executed. Ultimately, one needs to generate a number of models that represent the dimensions of the gas clouds that would result from leaks in the equipment being protected. These models need to consider weather conditions (wind direction, speed, and atmospheric stability), release orientations, and release frequency. Then, each of the gas clouds needs to be assessed, one at a time, to determine if the gas cloud comes into contact with any of the proposed gas detectors. This analysis results in the calculation of scenario coverage, or what fraction of the releases (considering their relative frequencies) will be detected by a given array of detectors. This coverage assessment is compared against a numerical target (e.g., 80%) that is defined for the area based on the level of risk that it poses. As you can imagine, this is not a trivial amount of work, but it is definitely manageable, especially if sophisticated 3D computer tools are employed to do the heavy lifting.
