Hydrogen Sulfide (H2S) Colorless gas Biological decay Olfactory
Rotten eggs odor Smell ppm Biological decay Sulfur-containing goods Sewage Manure Leafs, wood, animals Olfactory Deaden sense of smell ppm Chemical asphyxiate Rendering cells dead Chemical irritant Eye and upper airway

H2S properties Vapor density Vapor knockdown Venting Absorption
1.19 heaver than air Low to the ground Vapor knockdown Water spray Venting May not work Consider PPV Absorption Poisonous IDLH 100 ppm Autoignition 500°F Flammable gas LEL 4% UEL 44%
