Methyl Alcohol (wood alcohol, CH3OH, CAS 67-56-1) is the simplest alcohol. It is volatile and burns with a nearly invisible flame. Methyl alcohol is poisonous, and swallowing small amounts can cause blindness. It is used as an industrial solvent, antifreeze in gas pipelines and windshield fluid, a denaturant for ethanol, and in the chemical, plastics and pharmaceutical industries. Storage tanks need grounding, flame arrestors and secure venting. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
