Principle Routes of Exposure

Eye. Inhalation. Skin. Ingestion. Acute effects See component summary.  Methyl alcohol 67-56-1 May cause irritation to eyes, skin, and respiratory system. May cause drowsiness and dizziness. If ingested or inhaled, methanol may cause metabolic acidosis, blindness or death. Skin absorption of methanol may add significantly to the overall toxic effect. Skin Exposure to this material can result in absorption through skin causing a significant health hazard. May be mildly irritating to the skin. Inhalation Irritating to the respiratory system. May cause drowsiness and dizziness. Eyes May cause moderate irritation, including burning sensation, tearing, redness or swelling. Ingestion Swallowing as little as 1 to 2 ounces/25 to 50 grams of Methanol can result in metabolic acidosis leading to optic nerve damage ranging from diminished visual capacity to complete blindness, and death.

Potential chronic health

See component summary.  Methyl alcohol 67-56-1 Methanol is slowly eliminated from the body, therefore it can have cummulative toxicity effects with repeated exposures.

Medical Conditions Generally Aggravated by Exposure

Persons with existing skin, kidney, liver or eye disorders may be at increased risk when exposed to methanol.
