Hydrogen Sulfide in Workplaces

Hydrogen sulfide is produced naturally from decaying organic matter. It can be released from sewage sludge, liquid manure, and sulfur hot springs, and with natural gas. It is also used or is a by-product in many industrial processes such as:

• Petroleum production and refining
• Sewer and wastewater treatment
• Agricultural silos and pits
• Textile manufacturing
• Pulp and paper processing
• Food processing
• Hot asphalt paving
• Mining

Some nuclear power plants use hydrogen sulfide to produce heavy water, an alternative to regular water that enables nuclear reactors to use ordinary uranium fuel instead of enriched uranium. Farmers use H2S as an agricultural disinfectant and you'll find it in some cutting oils, which are coolants and lubricants designed specifically for metalworking and machining processes, and other lubricants. Hydrogen sulfide is also used in chemical warfare. Many industrial entities, such as iron smelters, landfills, food processing plants and breweries, produce or use hydrogen sulfide. If one of them disposes of this gas improperly or releases it accidentally, unwanted emissions may escape into the air.
