Jim Blais

Jim is the senior technical lead for Toxic Gas Monitoring Systems (TGMS) with 50 years of experience. He determines TGMS “user requirements”- evaluates, recommends, selects and applies the best gas detection technologies available – based upon each user’s gas targets. Jim also provides guidance on harmonizing and utilizing both applicable codes and best practices, selecting ideal sensor locations and developing functional “cause & effect” (CE) gas safety matrices.

Hazardous Gas Monitoring: Key Elements of a Safety Requirement Specification

Developing a Safety Requirement Specification (SRS) or functional “cause & effect” matrix for a Hazardous Gas Monitoring System is absolutely critical to identify and then eliminate potential gas related hazards. The approved SRS purpose is to provide people, equipment and the facility with safety and freedom from unacceptable risks.

How to Properly Select Hazardous Gas Monitoring Sensor Locations

In addition to assessing required gas detection technologies, their capabilities (and limitations) related to safe detection of the specified hazardous gas target, proper placement and mounting location of each hazardous gas monitoring sensor is equally critical to protecting people, equipment and the facility.

Toxic Gas Monitoring System Design - 20 Years of Lessons Learned and Shared

For the past 20 years, I have been focused exclusively on designing Toxic Gas Monitoring Systems (TGMS). It has been quite a journey.  I’ve had the opportunity to work on many TGMS projects on a large scale. I’ve also had many opportunities to work in small R&D facilities with only one tool.

Harmonizing Hazardous Gas Monitoring Code Requirements and Best Practices

The manner in which a “hazardous gas monitoring, safety shutdown system” is designed, configured (hardware and software), validated and maintained will determine its ability to detect risks and automatically activate safety measures to avoid very dangerous situations.
