BANGKOK — Two Australian teenagers and a British woman died from suspected methanol poisoning after drinking tainted alcohol in Laos. An American man and two Danes also died, though their exact causes of death have not been released. A New Zealander also has been sickened. The U.S. State Department issued a warning to travelers to be “alert to the potential risk of methanol poisoning.” But what is methanol, and how do you avoid it?
There are three main types of alcohol: ethanol, methanol and isopropyl. Ethanol is what is found in consumer spirits and is the only one intended for consumption. Isopropanol is the main ingredient in rubbing alcohol and hand sanitizers. Methanol, commonly called wood alcohol because it is the byproduct of wood distillation, is frequently used as fuel and in products such as antifreeze and solvents.
According to the Methanol Institute, the global trade association for the industry, drinking just 25 to 90 ml (0.7 to 3.0 ounces) of methanol can be fatal without proper medical treatment, but can be successfully treated if caught early.
