Sulfur Recovery Fact: Safe Handling of H2S


We all have heard how Hydrogen Sulfide smells like rotten eggs. But remember, that is in small concentrations. If it is in high enough concentration it will simply kill you.

Since H2S is heavier than air and may travel along the ground, it will collect in low-lying and enclosed, poorly-ventilated areas such as manholes, vaults and sewer lines. The primary route of exposure is inhalation and the gas is rapidly absorbed by the lungs. In high enough concentrations, the ability to smell the gas can be lost instantaneously. Therefore, DO NOT RELY on your sense of smell to indicate presence of H2S.

In addition, Hydrogen sulfide is high flammable and gas/air mixtures can be explosive. If ignited the gas burns to produce toxic gases.

Below are solid guidelines to follow when dealing with H2S Systems:
