Chloroform is used as a heat transfer medium in fire extinguishers, where it lowers the temperature of carbon tetrachloride. Sometimes these not-to-exceed levels differ among federal organizations because of different exposure times (an 8-hour workday or a 24-hour day), the use of different animal studies, or other factors. You may be exposed by breathing, eating, or drinking the substance, or by skin contact. There is some evidence that chloroform directly affects the central nervous system, along with the liver and kidneys; at high doses, it can cause respiratory depression and coma. Based on animal studies, the Department of Health and Human Services (DHHS) has determined that chloroform may reasonably be anticipated to be a carcinogen (a substance that causes cancer). Chloroform is a clear liquid with an ether-like odor and a slightly sweet taste. [48] Her autopsy establishing the cause of death was undertaken by John Fife assisted by Robert Mortimer Glover.

A knighthood for Simpson, and massive media coverage of the wonders of chloroform, ensured that Simpson's reputation remained high. 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. The mean lethal oral dose for an adult is estimated at 45g (1.6oz). [38], Although trichloromethane has properties such as its low boiling point and its low global warming potential of only 31 (compared to the 1,760 of R-22) which result in it having good refrigeration properties, there is little information to suggest that it has seen widespread use as a refrigerant in any consumer products.[39].
