he nose to the point where the person can no longer smell the gas. Concentrations of hydrogen sulphide can soar from 5 parts per million (ppm) to more than 500 ppm in seconds after agitation begins and concentrations of hydrogen sulphide above 600 ppm can render a person unconscious after taking only one or two breaths. Hydrogen sulphide is a naturally occurring, flammable gas. It is formed through the decay of organic matter. It is commonly found in areas where raw sewage or animal manure collect. Because it is heavier than air, the gas will collect in confined spaces. At low concentrations, it has a rotten egg smell, but at medium concentrations, H2S is perceived as sweet smelling. At high concentrations or after long-term exposure, the gas cannot be smelled. At low concentrations and short exposures, H2S is an eye and lung irritant. It causes watering eyes, coughing or a sore throat. As concentration levels or exposure times increase, the irritation worsens and can include headaches and fluid in the lungs. High concentration levels can cause a coma or death within a few breaths.
