• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: Rapid evaporation of the liquid may cause frostbite. The substance is irritating to the eyes and respiratory tract. Inhalation of this gas may cause lung oedema. The effects may be delayed. Medical observation is indicated. The substance may cause effects on the central nervous system. Exposure could cause unconsciousness. Exposure could cause death.
• Description: Sulfur belongs to a nonmetallic chemical element (pure product: yellow crystalline solid) under the symbol S. It can actively react with many other elements. It exists in various kinds of forms and compound such as sulfide and sulfate minerals which can be found everywhere around the universe and earth. It is also a key element for all life as the major component of amino acids, vitamins and many other cofactors. Sulfur has applications in various kinds of fields. For example, one of its biggest applications is for the production of sulfuric acid for sulfate and phosphate fertilizers. It is also used for the manufacturing of insecticides, fungicides, and bactericides. In pharmaceutical, it can be used for the manufacturing of many kinds of sulfur-containing antibiotics.
• Physical properties: Sulfur is considered a nonmetallic solid. It is found in three allotropic crystal forms:1. Orthorhombic (or rhombic) octahedral lemon-yellow crystals, which are also called“brimstone” and referred to as “alpha” sulfur. The density of this form of sulfur is 2.06g/cm3, with a melting point of 95.5°C.2. Monoclinic, prismatic crystals, which are light-yellow in color. This allotrope is referredto as “beta” sulfur. Its density is 1.96 g/cm3, with a melting point of 119.3°C.3. Amorphous sulfur is formed when molten sulfur is quickly cooled. Amorphous sulfur issoft and elastic, and as it cools, it reverts back to the orthorhombic allotropic form.Sulfur, in its elemental form, is rather common and does not have a taste or odor except whenin contact with oxygen, when it forms small amounts of sulfur dioxide.
• Uses: sulfur (colloidal) reduces oil-gland activity and dissolves the skin’s surface layer of dry, dead cells. This ingredient is commonly used in acne soaps and lotions, and is a major component in many acne preparations. It can cause allergic skin reactions. sulfur is a mild anti-septic used in acne creams and lotions. It stimulates healing when used on skin rashes. Sulfur may cause skin irritation. Elemental sulfur is used for vulcanizing rubber; making black gunpowder; as a soil conditioner; as a fungicide; preparing a number of metal sulfides; and producing carbon disulfide. It also is used in matches; bleaching wood pulp, straw, silk, and wool; and in synthesis of many dyes. Pharmaceutical grade precipitated and sublimed sulfurs are used as scabicides and as antiseptics in lotions and ointments. Important sulfur compounds include sulfuric acid, sulfur dioxide, hydrogen 890 SULFUR sulfide, sulfur trioxide, and a number of metal sulfides and metal oxo- salts such as sulfates, bisulfates, and sulfites. Numerous organic compounds contain sulfur, such as mercaptans, thiophenes, thiophenols, sulfate esters, sulfones, and carbon disulfide. Sulfur is one of the four major commodities of the chemical industry. The other three arelimestone, coal, and salt. Most sulfur that is produced is used to manufacture sulfuric acid(H2SO4). Forty million tons are produced each year in the manufacture of fertilizers, lead-acidbatteries, gunpowder, desiccants (drying agent), matches, soaps, plastics, bleaching agents,rubber, road asphalt binders, insecticides, paint, dyes, medical ointment, and other pharmaceuticalproducts, among many, many other uses. Sulfur is essential to life.
