Carbon bisulfide

Carbon disulphide (CS -2) - disulfide carbon. temperature boiling 46,3 degrees, the density of 1.26 (20 degrees). A volatile, colorless liquid with a pleasant odor (in the absence of impurities). On light decays, while yellow and unpleasant smell. Poorly soluble in water. Mixed in any ratio with alcohol, chloroform, ether. Vapours are heavier than air, flammable, form explosive mixtures with air.
Used carbon disulfide in viscose industry as a solvent; and in agriculture to control pests. May be contained in the technical and oil products to stand out in the synthesis of carbon tetrachloride.
The carbon enters the body through the respiratory organs and the skin. Is in an unmodified form with your breath, urine, faeces and sweat. In the body long delays in fat and nerve tissue. May cause acute, subacute and chronic toxicity with predominant affection of the nervous system.
Carbon disulphide has a narcotic effect, causes mental disorders with symptoms of elementary excitation, alternating with depression. Described cases of dementia, as a result of severe acute poisoning. Chronic poisoning develop slowly - there are moderately expressed phenomenon neurasthenia, vegetative polyneuritis with prevalence of disorders of sensitivity. In more severe cases, toxic encephalopathy with cerebral disturbances, autonomic crises, cardiovascular disease, parkinsonism. Simultaneously detected changes in the liver (hepatitis), mild anemia, irritation of the urinary system, changes in metabolism.
Severe poisoning were observed at concentrations of 1.0-1.5 mg/l, but can be and at lower concentrations. Chronic poisoning is possible at a concentration of 0.15 mg/l and below.
First aid - clean air, serenity, the oxygen. In case of need artificial respiration, heart funds (caffeine, camphor, kordiamin). In cases of chronic intoxication - suspension from work, vitamin B1, physiotherapy.
Prevention: industrial filter mask, at high concentrations - insulating gas masks. Obligatory training of employees. Preliminary and periodic (1 every 6 months). the medical examinations. Sealing equipment. Mechanization of labour processes at work as a disulfide. Maximum permissible concentration in the air of working premises 10 mg/m3.
