Deadly hydrogen sulfide (H₂S) can be present in industries such as oil & gas production and wastewater treatment. The Wikipedia Hydrogen Sulfide page highlights the danger:
Short-term, high-level exposure can induce immediate collapse, with loss of breathing and a high probability of death. If death does not occur, high exposure to hydrogen sulfide can lead to cortical pseudolaminar necrosis, degeneration of the basal ganglia and cerebral edema.[31] Although respiratory paralysis may be immediate, it can also be delayed up to 72 hours.[38]
In a Water Online article, Avoiding The Deadly Legacy Of Hydrogen Sulfide, Emerson’s Sean McLeskey is quoted:
“H₂S gas is naturally present and produced in wastewater treatment… It is found in raw sewage and throughout sludge processing stages, so it’s critical to monitor for the gas in sewers, sludge de-watering systems, anaerobic digesters, and wet/dry wells.”
As Sean indicates, continuous monitoring for H₂S is critical for personnel safety. Solutions: Continue Reading ▶
