Chloroform is a member of a group of chemicals called "trihalomethanes." Chloroform can be toxic if inhaled or swallowed. We interviewed a number of chemists working in chemical laboratories who explained that the chloroform smell vaguely resembles the smell of acetone, an organic compound. Although many of us associate chloroform with a fluid in a rag that knocks people out, its effects on the human body can be far more complex, and if not carefully monitored, chloroform can be fatal. Chloroform is a volatile liquid, so it quickly loses its effectiveness when it comes into contact with air. Another important point. It is used to make coolants, as a fumigant for grain, and as a dry WebChloroform (CHCl 3) is a colorless liquid that quickly evaporates into gas.

The use of Chloroform as an ingredient in cosmetic products has been banned since 1976. Formerly used during surgery as an inhaled anaesthetic, the main application of chloroform today is in agriculture, where it is used as a solvent, and also particularly in the manufacture of the refrigerant freon. These sites make up the National Priorities List (NPL) and the sites are targeted for long-term federal cleanup. While the right dose of chloroform soaked in a rag can definitely render you unconscious (the Lancet articles cites 5 minutes and persistance should knock someone out, but no experimental evidence was provided), it would take much longer than what they show in movies: you wouldnt drop unconscious just by taking a whiff! 0.2.22 GENOTOXICITY. Storing It. This compound was originally made by the reaction of ethanol or acetone with bleaching powder calcium hypochlorite. The rise of gas anaesthesia using nitrous oxide, improved equipment for administering anaesthetics and the discovery of hexobarbital in 1932 led to the gradual decline of chloroform narcosis.
