Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rot-ten egg” smell. Some common names for the gas include sewer gas, stink damp, swamp gas and manure gas. It occurs naturally in crude petroleum, natural gas, and hot springs.
A sewer gas smell is often a sign of plumbing issues, like a sewage backup in the basement or damaged drains. While it's easy to confuse the smell of sewer gas with a natural gas leak, as both can smell like rotten eggs, natural gas smells a bit more like the spray from a skunk than raw sewage.
Hydrogen sulfide (H 2 S) is a flammable, colorless gas that smells like rotten eggs. People usually can smell hydrogen sulfide at low concentrations in air, ranging from 0.0005 to 0.3 parts hydrogen sulfide per million parts of air (ppm).
12 Οκτ 2023 · A malfunctioning or overloaded septic system can contribute to sewer gas smells. Understanding the causes of a sewer gas smell can help you identify and address the underlying issue, ensuring a safe and odor-free environment in your home.
underestimated danger: Hydrogen sulfide, a toxic gas, which can unexpectedly occur during routine work. H 2 S is a gas that sneaks up on you because it is colorless and thus invisible. The distinctive rotten egg odor is perceptible only in low concentrations - at higher, more dangerous levels, H 2 S numbs a person‘s sense of smell. Inhalation
Description. Hydrogen sulfide is a colorless, flammable, highly toxic gas. It is shipped as a liquefied, compressed gas. It has a characteristic rotten-egg odor that is detectable at concentrations as low as 0.5 ppb. Routes of Exposure. Inhalation is the major route of hydrogen sulfide exposure. The gas is rapidly absorbed by the lungs.
