carbon tetrachloride (CTC) - a colorless readily evaporating liquid with a sweet odor reminiscent of chloroform.In contact with a flame or incandescent material decomposes to form phosgene (the latter is formed, even when smoking a cigarette in the air, where there is carbon tetrachloride).
used in rubber, paint industries as a solvent resins, rubbers, in the production of CFCs, fire extinguishers (not used at fires in small confined spaces because of the possible formation of phosgene) and other MPC -. 20 mg / m3,
enters through the respiratory system, the gastrointestinal tract (random reception), the intact skin.Provided in an unmodified form of light (exhaled air has the smell of carbon tetrachloride).Weak drug.It has a long aftereffect.It causes severe degenerative changes in parenchymal organs, the development of hepato-renal syndrome.Irritating, affects the lungs.
