moonshine safety -
"Poorly produced moonshine can be contaminated, mainly from materials used in construction of the
still. Stills employing used
automotive radiators as condensers are particularly dangerous; in some cases,
glycol, products from
antifreeze, can appear as well. Radiators used as condensers also may contain
lead at the connections to the plumbing. Both glycol and lead are poisonous and potentially deadly.
Although methanol is not produced in toxic amounts by fermentation of sugars from grain starches,[SUP][/SUP] contamination is still possible by unscrupulous distillers using cheap methanol to increase the apparent strength of the product. Moonshine can be made both more palatable and less damaging by discarding the "foreshot"—the first few ounces of alcohol that drip from the condenser. The foreshot contains most of the methanol, if any, from the mash because methanol vaporizes at a lower temperature than ethanol. The foreshot also typically contains small amounts of other undesirable compounds such as acetone and various aldehydes.
India has a thriving moonshine industry, and a methanol-tainted batch killed 143 people in December 2011.[SUP][/SUP]
Alcohol concentrations above about 50% alcohol by volume (100 proof) are flammable and therefore dangerous to handle. This is especially true during the distilling process when vaporized alcohol may accumulate in the air to dangerous concentrations if adequate ventilation has not been provided."
