(Energy Safety Canada)

This is the required H2S course for oil and gas sites. We also offer Standard First Aid and Confined Space.

About H2S (Hydrogen Sulphide)

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.

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.

The H2S Alive course is taught only by an Energy Safety Canada certified instructor.
