I get some info off wikipedia. The problem is that some of the google and wikipedia links seem to be considering chlorine or chlorinated water a form of chloroform. Is it?
This is off of wikipedia:
Safety
As might be expected for an anesthetic, inhaling chloroform vapors depresses the central nervous system. It is immediately dangerous to life and health at approximately 500 ppm, according to the United States National Institute for Occupational Safety and Health. Breathing about 900 ppm for a short time can cause dizziness, fatigue, and headache. Chronic chloroform exposure may cause damage to the liver (where chloroform is metabolized to phosgene) and to the kidneys, and some people develop sores when the skin is immersed in chloroform.
Though normally minute and diluted amounts are exposed to humans, chloroform can be harmful. Chloroform can be exposed via inhalation, ingestion of drinking water and foods made with chlorinated water, as well as dermal contact. It is readily excreted through exhalation, and minuscule amounts are excreted through urination and feces. The Environmental Protection Agency reports, a fatal oral dose of chloroform may be as low as 10 mL (14.8 g), with death due to respiratory or cardiac arrest [12]
