Known for its strong “rotten egg” odor at low concentrations, hydrogen sulfide (H2S) is a very flammable, highly corrosive, and toxic gas that can build up in low-lying areas and confined spaces, quickly overcoming unprotected workers.
Unfortunately, at higher concentrations, the gas no longer has an odour, making it even more dangerous.
“Very poisonous at even low concentrations, hydrogen sulfide is a colorless, extremely hazardous gas that can be rapidly absorbed by a worker’s lungs,” said Mark Stromme, editor of workplace safety content for J. J. Keller & Associates, Inc. “Exposure at very high concentrations can cause nearly instant death.”
To help protect workers, J. J. Keller has introduced two new online training courses on its Training On Demand website: Hydrogen Sulfide For General Industry and Hydrogen Sulfide For Oil & Gas.
Both courses help satisfy the training requirements in 29 CFR 1910.1200, 1910.119 and ANSI Z390.1-2006. They familiarise affected workers with the hazards of hydrogen sulfide, detection methods, and the best responses to exposure and release of the gas.
