Antimony - a silvery-white metal.It is used in various alloys (printing, anti-friction, babbitt).antimony oxides (antimony antimony anhydride and anhydride) are used for the manufacture of fire-resistant textiles, fire-resistant paints, found in the air of industrial premises in the smelting of antimony.antimony potassium tartrate (tartar emetic) - colorless crystals.It is used as a medicine and as a mordant in textile production.Antimony sulfides and chlorides are used for coloring of metallic products for rubber vulcanization, etc. of antimony fluoride -.. Colorless crystals used in the textile industry.MPC dust antimony - 0.5 mg / m3, to fluorides and chlorides (in terms of Sb) - 0.3 mg / m3 for the trivalent oxides and sulfides as a dust (in terms of Sb) - 1 mg / m3to pentavalent oxides and sulfides as a dust (in terms of Sb) - 2 mg / m3.
Antimony and its compounds enter the body primarily through the respiratory system.Antimony is deposited in the liver, skin and hair.Trivalent antimony compounds
When exposed to antimony compounds in the form of vapor observed irritation of eyes (possible corneal damage), and upper respiratory tract.Inhalation of antimony oxide fume (generated during melting or burning antimony paints) cause metal fever symptom.After contact with antimony compounds in the stomach (possible household poisoning tartar emetic, food or beverages stored in enamelware, glazed enamel antimony) observed phenomena similar to symptoms of acute food poisoning.
Inflammatory diseases of the nasopharynx and trachea, mostly atrophic character, bronchitis and conjunctivitis, stomatitis, the appearance of bluish border on the gums, gastrointestinal disorders (anorexia, constipation or diarrhea, etc.), Functional disorders of the central nervous system (insomnia, headaches, irritability, dizziness, weakness), diencephalic syndrome.Polyneuritis possible, damage to the heart muscle, arterial hypotension.
antimony dust during long-term inhalation can cause lung disease - pneumoconiosis (antimopokonioz), predominantly interstitial sclerosis with severe forms of hilar lymph nodes, not progressive after cessation of exposure to antimony dust.
We antimony metallurgical plant workers revealed frequent menstrual disorders and impaired fertility (spontaneous abortions in later stages of pregnancy, and others.) And lagging in the growth of children.
Workers engaged in smelting of antimony metal, frequent skin diseases with symptoms of pruritus, erythema, dry skin (cracks), pustular rash, eczema, localized on the head, face, na folds of joints (with penetration of dust under the clothing).
in blood - moderate anemia, leukocytosis, eosinophilia.The urine is often a protein is determined.
First aid and treatment
In acute inhalation poisoning - alkaline inhalations, to drink plenty of warm sweet tea or coffee, aspirin, aminopyrine.In acute oral poisoning - repeated gastric lavage solution of tannin, protein water.Mucous drinks warm milk.Enema of decoction of flax seed with the addition of tincture of opium (10 drops).If severe vomiting - swallowing pieces of ice, morphine subcutaneously.According to the testimony - cardiovascular drugs intravenously - isotonic sodium chloride solution, glucose.As an antidote used unitiol apparently, effective only in case of poisoning by trivalent antimony compounds.
disability For the initial manifestations of chronic intoxication is recommended temporary suspension from contact with antimony and its compounds with the appropriate treatment.At relapse of poisoning or in the presence of severe chronic intoxication requires translation should work not related to the impact of antimony and its compounds.
Smelting Antimony - local extraction systems.Personal protective equipment.
