What is Hydrogen Sulfide?
Hydrogen sulfide (also known as H2S, sewer gas, swamp gas, stink damp, and sour damp) is a colorless gas known for its pungent “rotten egg” odor at low concentrations.

It is extremely flammable and highly toxic.

How does it happen and what is it for?
Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes.

Because it is heavier than air, hydrogen sulfide can collect in low-lying and enclosed spaces, such as manholes, sewers, and underground telephone vaults. Its presence makes work in confined spaces potentially very dangerous.

The health effects of hydrogen sulfide depend on how much H2S a worker breathes and for how long.
However, many effects are seen even at low concentrations. Effects range from mild, headaches or eye irritation, to very serious, unconsciousness and death.

Where is hydrogen sulfide used?
It is used in the production of sulfuric acid H2SO4 and other sulfur compounds, pesticides, inorganic sulfides, in various segments of the oil industry such as well drilling, oil and gas production, refining and distillation, in chemical analysis and as a reducing agent in acid purifications. sulfuric and hydrochloric acid HCl.
