Antimony (Stibium, Sb) is a chemical element V of groups of periodic system of D. I. Mendeleev, number 51, atomic weight 121,7. Silvery-white metal melting point 630 degrees boiling point 1625 degrees, the density 6,684, insoluble in water, when burning produces oxides.
Antimony is used in various alloys. Compounds of antimony is used in the preparation fireproof textiles, fireproof paints, mordant agent in textile industry, pharmaceutical industry, at vulcanization of rubber.
Compounds of antimony enter the body in the form of vapour and dust through the respiratory tract and intestinal tract.
Acute poisoning is celebrated irritation of mucous membranes of the upper respiratory tract and eyes. Hit in the stomach causing metallic taste in the mouth, nausea, vomiting, salivation, diarrhea, abdominal pain, and in severe cases convulsions, collapse, delay Department of urine.
At influence of oxides of antimony (smelting) occurs fever (casting sormana fever), accompanied by chills, difficulty breathing, asthma, elevation of body temperature, pain in the chest, leg.
Persons in prolonged contact with antimony, it may cause dermatitis (see), General weakness, indigestion, can be constipation or diarrhea, weight loss, inflammation in the mouth, itching, skin cracks.
First aid. In case of poisoning through the respiratory tract must drink plenty of water (warm sweet tea, coffee), acetylsalicylic acid, amidopyrine.
If you get antimony compounds in the stomach repeated gastric lavage solution of tannin, drink warm milk, enveloping drinks.
In acute dermatitis cool gadgets, when piodermatitis syntomycin and streptomicine emulsion. For treatment of cracks apply bactericidal plasters, collodion.
Prevention: in the presence of dust the use of respirators, use of mittens or gloves made of thick fabric. When melting of antimony use local ventilation devices. Maximum permissible concentration of antimony - 0.5 mg/m3, smoke trioxide and trekhmernoi antimony - 1.0 mg/m3, dust paternity and pentoxide antimony - 3 mg/m3.
