Hydrogen sulfide (H2S) is a highly toxic gas, with lethal levels typically starting at concentrations above 700 parts per million (ppm). Exposure to H2S at this level can lead to rapid respiratory failure and death within minutes. Even lower concentrations (around 100 ppm) can cause serious health effects, including loss of consciousness. Safety precautions are essential in environments where H2S may be present.
