Hydrogen Sulfide, or H2S, is known as the “Silent Killer” because you can’t see or smell it, and it’s so powerful that it can kill you with just one breath.

Protect your workers with this lifesaving training that teaches how to control the hazard and how workers can protect themselves.

Which Industries need H2S Training?

Oil & Gas Industry: Upstream, Midstream, and Downstream

  • Oil and natural gas wells; in refineries, where H2S is removed from natural gas and oil
  • Pipelines and tankers used to carry unrefined petroleum: Shale Shaker Areas, Fluid Treatment Areas, Rig Floor, Belle Nipple, Mud Tanks, Mud Pump Areas, Storage Tanks, Wellhead, Cellar, Drilling Floor, Pump Houses, Gas Processors, Manure Tanks & Ponds, Plug Flow Digesters, Storage Tanks, Transportation (trucks, barges and rail cars)
  • Underground Natural Gas Storage Facilities

Pulp and Paper Industry

  • H2S is a by-product of wood breaking down into pulp in making paper, fertilizers, glues, dyes, plastic wrap, etc.

Construction Industry

  • Underground Utilities and Excavation work in swamps or landfills, Wastewater/Sewage Industry, sewers, septic tanks, and sewage treatment plants.

Agriculture Industry

  • Manure tanks, bogs, swamps, and other places where organic material breaks down without oxygen.

Other Areas

  • Mining, tunnels, coke ovens, coal-fired plants, and animal processing plants.
