Hydrogen sulfide (also known as H 2 S, sewer gas, swamp gas, stink damp, and sour damp) is a colorless gas known for its pungent "rotten egg" odor at low concentrations. It is extremely flammable and highly toxic.
Hydrogen Sulfide - Hazards - Occupational Safety and Health …
Hydrogen sulfide is a highly flammable, explosive gas, and can cause possible life-threatening situations if not properly handled. In addition, hydrogen sulfide gas burns and produces other toxic vapors and gases, such as sulfur dioxide.
Hydrogen Sulfide (H 2S) 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. In addition, hydrogen sulfide is produced by bacterial break-
