Hydrogen Sulfide (H2S)

Hydrogen Sulfide is a colorless, flammable, extremely hazardous gas with a "rotten egg" smell. Also known as sewer gas, stink damp, swamp gas and manure gas. Industrial activities that can produce H2S gas include petroleum/natural gas drilling and refining, wastewater treatment, coke ovens, tanneries and kraft paper mills.

Hazardous properties of H2S Gas

Hydrogen Sulfide is heavier than air and may travel along the ground. It is prone to collecting in low lying and enclosed, poorly ventilated areas. (Basements, Manholes, Sewer Lines, underground telephone vaults and manure pits).

For work within confined spaces, use appropriate procedures for identifying hazards and monitoring and entering confined spaces.

H2S Gas is rapidly absorbed by the lungs. The "rotten egg" odor of H2S is only detectable at low concentrations in the air. Continuous low-level exposure or at high concentrations cause a person to lose the ability to smell the gas. This is known as olfactory fatigue. This can happen very rapidly at high concentrations. DO NOT RELY ON YOUR SENSE OF SMELL TO INDICATE THE CONTINUING PRESENCE OF HYDROGEN SULFIDE.

Hydrogen sulfide is a highly flammable gas and gas/air mixtures can be explosive. If ignited the gas burns to produce toxic vapors and gases such as sulfur dioxide.

Health effects of H2S Exposure

Hydrogen Sulfide is an irritant and a chemical asphyxiant - affecting both oxygen utilization and the central nervous system. Repeated exposures can result in negative effects occurring at levels that were previously tolerated without effect.

Low Concentrations: Cause burning and tearing of the eyes, coughing and shortness of breath. The effects can be delayed for several hours or days.

Repeated or Prolonged Low Level Exposure: Eye inflammation, headache, fatigue, irritability, insomnia, digestive disturbances and weight loss.

Moderate Concentrations: Coughing, difficulty breathing, accumulation of fluid in the lungs, headache, dizziness, nausea, vomiting, staggering and excitability

High Concentrations: Shock, convulsions, inability to breath, extremely rapid unconsciousness, coma and death. Effects can occur within a few breaths and possibly within a single breath.
