Although the odor of hydrogen sulfide is detectable at very low concentrations, it rapidly causes olfactory fatigue at higher levels, and therefore is not considered to have adequate warning properties. Hydrogen sulfide has not been shown to be carcinogenic or to have reproductive or developmental ...

Odor and Warning Properties: Hydrogen sulfide has an extremely unpleasant odor, characteristic of rotten eggs, and is easily detected at low concentrations: however, due to rapid onset of olfactory fatigue and paralysis (inability to smell) ODOR SHALL NOT BE USED AS A WARNING MEASURE.Exposure...
Hydrogen sulfideis easily identified by its smell of rotten eggs, detection of which is diminished with prolonged exposure (olfactory fatigue). It is also anirritantto the eyes and mucous membranes.Hydrogen sulfideis most closely associated with the phenomenon of knockdown, which may occur immediately...
fatalities have occurred to rescuers entering the hot zone. C Hydrogen sulfide is a colorless, highly flammable and explosive gas produced naturally by decaying organic matter and by certain industrial processes. Hydrogen sulfide has a characteristic rotten-egg odor; however, olfactory fatigue may occur...
hydrogen sulfide Thesaurus Medical Acronyms Encyclopedia Wikipedia Related to hydrogen sulfide:hydrogen sulfide poisoning n. A colorless, flammable poisonous gas, H2S, having a characteristic rotten-egg odor and used in metallurgy, and as an antiseptic, bleach, and reagent. ...
Due to hydrogen sulfide’s low odor threshold—often described as smelling like rotten eggs—relying on smell for detection is unsafe, as olfactory fatigue can set in during prolonged exposure. Therefore, occupational safety measures are critical, including the regular calibration of gas detection equi...

A particular danger when handling H_2S is that continuous exposure may lead to olfactory fatigue. If this condition occurs then the user will be unable to smell the characteristic foul odor of H_2S.~(1,2)Rodney W.SpitlerProceedings of the Seventy-Fourth International School of Hydrocarbon ...
In addition, brief exposure to H2S at ≥ 50 ppm or extended exposure at 5–10 ppm may lead to olfactory fatigue (deadening of the sense of smell) and cause a person to lose the ability to detect many toxic substances, even at deadly concentrations [9,10]. A number of techniques have ...
