). Dust particles may be irritating to the eyes, nose, throat, and skin. (Sulfur Fact sheet ). Molten sulfur can cause thermal burns. Molten sulfur may evolve hydrogen sulfide (toxic gas) which may accumulate in storage container vapor space. (Sulfur Fact sheet ). High concentration may cause immediate unconsciousness, death may result unless victim is promptly and successfully resuscitated. Hydrogen sulfide causes eye irritation. (Sulfur Fact sheet ).
Sulfur was known in ancient times and referred to in Genesis as brimstone.( , Sir Edward Thorpe 1914). Assyrian texts dated around 700-600 BC refer to it as the "product of the riverside", where deposits could be found. In the 9th century BC, Homer mentioned "pest-averting sulfur". (, Sir Edward Thorpe 1914). In 424 BC, the tribe of Bootier destroyed a city's walls using a burning mixture of coal, sulfur, and tar. (, Sir Edward Thorpe 1914). Sulfur is one of the elements which has an alchemical symbol, shown below (alchemy is an ancient pursuit concerned with, for instance, the transformation of other metals into gold). (, Sir Edward Thorpe 1914). Alchemists knew that mercury can be fixed with sulfur. Possibly Antoine Lavoisier should be credited with convincing the scientific community that sulphur is an element (around 1777). (, Sir Edward Thorpe 1914). Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same combination of these atoms. (, Sir Edward Thorpe 1914). Dalton also noted that in series of compounds, the ratios of the masses of the second element that combine with a given weight of the first element can be reduced to small whole numbers (the law of multiple proportions). (, Sir Edward Thorpe 1914). This...
