<p>[QUOTE=&quot;TheNickelGuy, post: 1493421, member: 20201&quot;]Is hexane dangerous?</p><p><br /></p><p>Answer:</p><p>According to the Material Safety Data Sheet, <b><span style="color: #FF0000">Hexane is very dangerous.</span></b> It is Harmful, Dangerous to the Environment, and Highly Flammable.</p><p>Stability:</p><p>Hexane is stable, however it is incompatible with oxidizing agents, chlorine, fluorine and magnesium perchlorate. It also readily forms explosive mixtures with air and has a low flash point.</p><p>Toxicology: </p><p>Hexane may cause impaired fertility and CNS Depression. It is an irritant and it is harmful if inhaled. Prolonged exposure may also cause serious health damage.</p><p>Environmental Information: </p><p>Hexane is harmful in the environment and may cause long-term effects.</p><p>Personal Precautions: </p><p>One should wear safety glasses and a lab apron. Appropriate ventilation is needed such as a fume hood. All sources of ignition need be removed from the working area.</p><p><br /></p><p>&nbsp;</p><p><span style="color: #FF0000"><b>Chloroform is very dangerous</b></span></p><p>Chloroform is no longer available to the general public and for good reason. What would you be using it for? There are usually safer alternatives.</p><p>&nbsp;</p><p>Despite the fact that we see people getting knocked out by Chloroform on TV/Movies all of the time. You should know that it is a pretty dangerous level. If you can even smell chloroform in the air you are actually above the legal exposure limit for chloroform. Any waste chloroform must be treated as a highly toxic waste.</p><p>&nbsp;</p><p>FROM WIKIPEDIA:</p><p>&nbsp;</p><p>As might be expected from its use as a anesthetic, inhaling chloroform vapors depresses the central nervous system. It is immediately dangerous to health and life at approximately 500 ppm according to the United States National Institute for Occupational Saftey and Health. Breathing about 900 parts of chloroform per million parts air (900 parts per million) 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.</p><p>&nbsp;</p><p>Animal studies have shown that miscarriages occur in rats and mice that have breathed air containing 30 to 300 ppm chloroform during pregnancy and also in rats that have ingested chloroform during pregnancy. Offspring of rats and mice that breathed chloroform during pregnancy have a higher incidence of birth defects, and abnormal sperm have been found in male mice that have breathed air containing 400 ppm chloroform for a few days. The effect of chloroform on reproduction in humans is unknown.</p><p>&nbsp;</p><p>Chloroform once appeared in toothpastes, cough syrups, ointments, and other pharmaceuticals, but it has been banned in consumer products in the United States since 1976.[/QUOTE]</p><p><br /></p>
