- CCOHS: Hydrogen Sulfide
Other Names: H2S, hydrogen sulphide, sour gas, sewer gas Main Uses: Manufacture of other chemicals; manufacturing processes; environmental contaminant; by-product of industrial processes Appearance: Colourless gas Odour: Rotten eggs Sickening sweet odour at high concentrations Can dull the sense of smell Canadian TDG: UN1053
- CCOHS: Respirators - Respirator Selection
What are "immediately dangerous to life or health" (IDLH) considerations? Back to top Some types of atmospheres place the worker in immediate danger because the concentrations of hazardous contaminant would impair the ability to leave the work area (self-rescue) or potentially cause irreversible health effects, serious injury, or death in a matter of minutes
- CCOHS: Occupational Hygiene - Occupational Exposure Limits
What are the occupational exposure limits? Back to top In general, the occupational exposure limit (OEL) indicates the level of admissible exposure, for a length of time (usually 8 hours), to a chemical or physical hazard that is not likely to affect the health of a worker

H2S, hydrogen sulphide, sour gas, sewer gas Main Uses: Manufacture of other chemicals; manufacturing processes; environmental contaminant; by-product of industrial processes Appearance: Colourless gas Odour: Rotten eggs Sickening sweet odour at high concentrations Can dull the sense of smell Canadian TDG: UN1053
- CHEMINFO: Hydrogen sulfide - CCOHS
Wet or moist H2S is corrosive to copper, brass, bronze, cast iron, types 1010 and 1020 carbon steel (100% concentration at temperatures of 21-65 5 deg C (70-150 deg F), lead, Monel and 400 series stainless steels (61,74- 76) It has been reported that wet H2S can corrode carbon steel at corrosion rates that can exceed 2 5 mm year, depending on
- CCOHS: Battery Charging - Industrial Lead-Acid Batteries
What are the risks of charging an industrial lead-acid battery? Back to top The charging of lead-acid batteries (e g , forklift or industrial truck batteries) can be hazardous
- CCOHS: Welding - Fumes And Gases
What are the health effects of welding fumes and gases? Back to top The International Agency for Research on Cancer (IARC) has classified welding fumes as carcinogenic to humans (Group 1)
- Hydrogen Sulfide Lewis Structure - Seymour Hub
The Lewis structure of H2S is constructed by placing the sulfur atom at the center, bonded to two hydrogen atoms, with two lone pairs on the sulfur atom The molecule has a bent or V-shaped geometry due to the presence of lone pairs on the sulfur atom, which is consistent with VSEPR theory
