H2S har en karakteristisk lukt av ruttet ägg, men luktsinnet bedövas snabbt och frånvaro av lukt är inget säkert kriterium för att det inte finns gas. • 1-150 ppm C6H12, 1000ppm: ~110 min, EN >70 Resistenstid B1 Klor Cl2, 1000 ppm: ~130 1000 ppm: ~40 min**, EN >25 Resistenstid B1 Svavelväte H2S, 1000 ppm: resistenstid A1 Cyklohexan C6H12, 1000ppm: ca. resistenstid B1 Klor Cl2, 1000 ppm: ca. resistenstid B1 Svavelväte H2S, 1000 ppm: 210 min** [>40] H2S (Hydrogen Sulfide) is a highly toxic gas that can kill or seriously harm human health when exposed to it, even at low concentrations like 10 parts per million (ppm).

530–1000 ppm causes strong stimulation of the central nervous system and rapid breathing, leading to loss of breathing. 800 ppm is the lethal concentration for 50% of humans for 5 minutes' exposure . Concentrations over 1000 ppm cause immediate collapse with loss of breathing, even after inhalation of a single breath. Incidents 2020-11-03 about 100 ppm* People are no longer able to smell this gas at these concentrations.
