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.

Webinar: 7 Reasons Why Toxic Gas Monitoring Systems and Fire Alarm Systems Should Communicate 

Whenever the subject of wiring or communicating between a TGMS and a FAS comes up, there are usually negative responses and concerns that these two systems should “talk” to each other.  However, once the subject is discussed thoroughly, it becomes clear that they should or need to communicate.

White Paper: Toxic Gas Monitoring System Design - 20 Years of Lessons Learned

"A TGMS designer should be motivated by the simple fact that many of its “gas targets” actually have no warning properties… yet they can quickly cause great harm and death. A good example of this being areas of oxygen deficiency. 

The following is a brief summary of some key lessons learned along the way, followed with a few more details, along with real experiences (true stories) shared, perhaps highlighting the challenges and the need to pay attention to the… details"
