Case Study: Safe, Reliable, and Compliant Toxic Gas Monitoring Systems

A leading-edge semiconductor manufacturer committed over $10 Billion to build their campus with a goal of becoming the largest foundry in the United States.  Construction of the new Fab was a significant undertaking with an aggressive schedule. To select a provider of the Toxic Gas Monitoring System (TGMS) for the site, several items were identified as being important.

White Paper: Fundamental Design Requirements of TGMS

The manner in which a “toxic gas monitoring, safety shutdown system” is designed, harmonized (hardware and software), validated and maintained will determine its ability to detect risks and automatically activate safety measures to avoid very dangerous situations. Read our whitepaper to  learn best practices based on years of studying codes, attending (SESHA) seminars, collaborating with other safety professionals and designing world class toxic gas monitoring systems.

White Paper: 20 Years of Lessons Learned with TGMS

"For the past 20 years I have been focused exclusively on designing Toxic Gas Monitoring Systems (TGMS) on a large scale and in small R&D facilities with only one tool.

Large scale opportunities begin with the first “LonWorks” based TGMS, configured in Germany and installed in the USA with MST. This TGMS was initially a 600 point gas detection system installed at the “White Oak Semiconductor” FAB in Virginia.

We were fortunate to begin our “learning process” at Hallam-ICS by actually “teaming” with major gas detection manufacturers. At their request, we initially did the upfront and final designs, with our teaming relationships including Zellweger Analytics (now Honeywell Analytics) and now also with DOD Technologies and Draeger.

Over the years our involvement and capabilities has expanded to where we now provide turnkey services, beginning with user requirements, design, fabrication, installation, integration and validation of TGMS platforms."
