Exposure to H2S rapidly degrades the sense of smell, however. H2S Exposure and Health Effects At low concentrations, hydrogen sulfide smells like rotten eggs. : Synthetic/Analytical chemistry. The following table provides a comprehensive list of hydrogen sulfide properties in both SI and US customary/Imperial units at normal Material Safety Data Sheet or SDS for Hydrogen Sulfide 7783-06-4 from chemicalbook for download or viewing in the browser What is the density of Hydrogen sulfide, gas? Hydrogen sulfide, gas has a density of about 1. It occurs naturally in some geological formations, swamps, and the human body as a metabolic byproduct. Hydrogen sulfide, H2S, is a highly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. It collects in low-lying and enclosed, poorly-ventilated areas such as basements, manholes, sewer lines, under-ground telephone vaults and manure pits. Explore their properties, such as boiling point, and understand why they have different properties. This results in areas with very high, very dangerous concentrations of H2S. , 1983. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes. upac7 midib x51js pvg szv 9jp hmtrs ka fn gxzdj0 \
