10F    Hydrogen Sulfide (H2S Gas): A Toxic Killer (Basic)
Charles “Lewis” Raymond – The Gray Insurance Company

Hydrogen sulfide, also known as H2S, is one of the most dan-gerous gases encountered in industry. Hydrogen sulfide is a toxic gas that occurs naturally due to the bacterial decomposition of organic material, or occurs as a product, byproduct, or waste material result-ing from industrial processes. Construction active ties that could be impacted by hydrogen sulfide include projects in oil refineries, chemical plants, pulp mills, landfills, and sewerage treatment facili-ties. The purpose of this presentation is to provide attendees with an overview of hydrogen sulfide, its chemical and physical properties, sources of H2S, work practices, methods of detection, personal pro-tective equipment, contingency planning, rescue and first aid.
