OSHA Hydrogen Sulfide (H2S) Fact Sheet

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.  Features Poster size 11” x 17” Poster is available in English and in Spanish Front and back sides are laminated Quality printing in full color Attorney Approved Recycled Paper Made in USA Poster content is guaranteed to be up-to-date
