Safety Information about Hydrogen Sulfide H2S

Hydrogen sulfide has a signature smell of “rotten egg” and is known by several different names including swamp gas, manure gas, stink damp and sewer gas. It is a very hazardous gas that is colorless and flammable.

There are several industrial applications and activities that produce hydrogen sulfide such as the drilling and refinement of crude petroleum, wastewater treatment, tanneries, coke ovens, and paper mills.You can check this link https://h2szero.com/ to know more about purification solutions.

Essentially, hydrogen sulfide occurs when bacteria breaks down organic matter such as human or animal waste.

The Dangers of Hydrogen Sulfide

Hydrogen sulfide is a chemical asphyxiant which means that even low concentrations of this gas affect the body’s ability to maintain an adequate oxygen supply because the oxygen cannot be transferred to the cells. Carbon monoxide is another example of a chemical asphyxiant.

Even though hydrogen sulfide has a distinctive smell of “rotten egg,” workers that are consistently exposed to the gas they will lose the ability to smell the gas even though it is present.

This loss of smell can happen very quickly or even instantaneously which makes working in an environment where there is a possibility of consistent exposure to hydrogen sulfide very dangerous.

Hydrogen sulfide is also a highly flammable gas. When the gas mixeswith air it can cause an explosion.

The gas may also travel towards a source of ignition and cause flashback. When the gas is ignited it burns and produces toxic vapors like sulfur dioxide. Lastly, direct exposure with liquid hydrogen can cause severe frostbite.

Health Effects of H2S

In low concentrations exposure to hydrogen sulfide can irritate the eyes, nose, throat and respiratory system. A person exposed to the gas may experience shortness of breath, coughing, and tearing. Long term exposure can also cause headaches, fatigue, digestive problems, insomnia, irritability and weight loss.
