Core 10 introduction to hydrogen sulfideWayneBourg
Hydrogen sulfide, or H2S, is a hazard that can creep up on you. You cannot see it, and if the concentration is high enough, you will not even be able to smell it. This toxic gas is colorless and collects in low-lying areas. H2S is so powerful that it can kill you with one breath. It is known as “The Silent Killer.” In this chapter, we will review the safe work practices designed to protect you from hazardous exposure to H2S.
Hydrogen Sulfide (H2S)
Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten
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. In addition, hydrogen sulfide is produced by bacterial breakdown
of organic materials and human and animal wastes (e.g., sewage).
Industrial activities that can produce the gas include petroleum/natural gas
drilling and refining, wastewater treatment, coke ovens, tanneries, and kraft
paper mills. Hydrogen sulfide can also exist as a liquid compressed gas.
All you need to know about Hydrogen Sulfide - H2SOizom
H2S is formed whenever elemental sulfur or sulfur-containing compounds come into contact with organic materials at high temperatures. Continuous or high-level exposure of the H2S can quickly deaden a person’s sense of smell, making the odour of H2S an unreliable indicator of its presence. Hence, other means such as hydrogen sulfide monitoring is a viable solution to provide adequate warning of hazardous exposure. This article covers information on hydrogen sulfide, its sources in the ambient air, permissible levels, health and environmental impact. Additionally, it also highlights possible corrective measures, the need for H2S monitors and different methods of H2S monitoring.
What is H2S?
H2S is colorless, flammable, poisonous, and corrosive gas with one sulfur atom bonded to two hydrogen atoms. Known as sewer gas, swamp gas or manure gas, H2S has a noticeable rotten-egg odour detectable at concentrations as low as 0.5 ppb. Also, It is highly flammable, explosive gas between 4% and 45% (concentration in air) which may travel to ignition sources and flashback. When ignited, it burns to produce toxic vapors and gases (sulfur oxides).
H2S molecular structure

Hydrogen sulfide is slightly heavier than air. It may travel along the ground collecting into low lying, enclosed, or poorly ventilated areas such as basements, sewer lines, underground passages, manholes, etc.
Hydrogen sulfide in Atmosphere
H2S is present naturally in crude petroleum, natural gas, and hot springs. It is released into the atmosphere primarily as gas from volcanoes, geothermal vents, sulfur springs and lakes, salt marshes, and estuaries. Also, bacterial breakdown (anaerobic decay) of organic sulfur compounds also produce H2S.
