Hydrogen Sulphide (H2S) is a highly toxic and flammable gas. Each year in Canada, workers are injured and killed by exposure to H2S. H2S Awareness explains the properties of H2S, identifies control measures, and provides a practical description of what to do in the event of exposure. H2S Awareness is a great introductory course for those looking to continue on to complete the H2S Alive certification or those looking to better understand the extremely dangerous hazards associated with H2S.
