Hydrogen Sulfide (H2S)

Hydrogen sulfide (H2S) is a colorless, flammable, and extremely toxic gas that is emitted from natural sources and certain industrial activities. H2S is heavier than air and collects in low-lying, enclosed areas, and the primary route of exposure is inhalation. In lower concentrations, H2S exposure causes eye, nose, throat, and respiratory irritation. Higher concentrations can induce shock, unconsciousness, and, in severe cases, death. Considering these hazardous effects, monitoring for H2S is a key factor in safeguarding personnel.

TAS is the world leader in H2S open path monitoring solutions. The health and safety of employees and sensitive populations surrounding a refinery or process plant is paramount. Although every employee onsite can rely on their personal H2S monitors, being able to detect a leak BEFORE an employee is exposed is invaluable. Furthermore, protecting nearby populations from leaks leaving your site protects your personnel’s families.

Although H2S is a tricky gas to monitor, TAS is at the cutting edge of new and improved technology, offering fast and reliable detection lightyears ahead of electrochemical sensors. Electrochemical sensors are poisoned easily and Optical Remote Sensing (ORS) systems can confused ammonia with water vapor. Yet, TAS has successfully installed dozens of open path H2S detection systems because we know what it takes to optimize the technology to your site’s specific characteristics.
