Hydrogen sulphide is an extremely hazardous gas that occurs naturally in crude petroleum and natural gas.

It is found in formations that are being drilled for oil, the gas is formed by the decomposition of organic matter containing sulphur. Hydrogen sulphide is a highly toxic, colorless, combustible gas. It is heavier than air and has the unmistakable odor of rotten eggs. High concentrations can cause shock, convulsions, inability to breathe, rapid unconsciousness, coma and death, and the effects can occur within as little as a single breath.

Usually, the poisoning it causes is through inhalation and has a toxicity similar to cyanide. Not only found in petroleum and natural gas but sometimes present in groundwater as well.
