Hydrogen sulfide gas is a common hazard in the oil and gas industry. Upon completion of this learning event, employees will demonstrate knowledge of the sources of hydrogen sulfide, its physical and chemical properties and effects on the body, hydrogen sulfide exposure controls and exposure response.
