Hydrogen Sulfide, Dry or Wet - Chemical resistance

Sulfane

Hydrogen sulphide or sulphane is a colourless, flammable and toxic gas. It has an odour similar to that of rotten eggs. It is used in a variety of industrial processes, such as the production of sulphuric acid, and in the refining of petroleum products. It is also used in the production of fertilisers and in some medical procedures. It is dangerous if inhaled and can cause serious health problems if swallowed. Moist hydrogen sulfide is a solution of hydrogen sulfide in water.
