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-

H2S accumulation and knockdown It is possible for H 2 S gas to accumulate in any low area or in enclosed areas, such as gas venting systems, mud systems, cellars, pits, and tanks. A condition referred to as "knockdown," or swift unconsciousness, can occur in such locations, with collapse occurring with 1 to 2 breaths.
