Hydrogen Sulfide (H₂S)
CAS Number:
7783-06-4
Hydrogen sulfide (H₂S) is a colorless, flammable gas with the distinctive odor of rotten eggs at low concentrations. It is produced naturally by the decomposition of organic matter and is a major byproduct in oil and gas production, wastewater treatment, pulp and paper manufacturing, and livestock confinement facilities. At low concentrations, H₂S causes eye and respiratory irritation; at moderate levels it causes headache, dizziness, and nausea. A critical hazard is that high concentrations rapidly desensitize the olfactory nerve (olfactory fatigue), eliminating the warning odor and leading to rapid incapacitation and death. H₂S monitoring is a life-safety requirement in oil fields, sewers, and confined spaces.
Hydrogen sulfide (H₂S) is a highly toxic gas commonly encountered in refineries, natural gas processing, wastewater treatment, and confined spaces such as manholes and lift stations. Rent H₂S detection equipment from RAECO Rents to support confined space entry screening, personal monitoring, and leak checks where sulfur compounds may be present. All rental instruments are bump tested before each rental to help crews confirm proper sensor response before heading into the field.
