H2S is a colorless, flammable, and corrosive gas with an odor similar to rotten eggs. People can lose their ability to smell H2S, even at low concentrations, a condition called olfactory fatigue. Because of olfactory fatigue, OSHA warns that the sense of smell should not be used as a detection method. According to the National Institute for
