Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
Methanol toxicity (also methanol poisoning) is poisoning from methanol, characteristically via ingestion. [1] Symptoms may include an altered/decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. [1] [2] Decreased vision may start as early as twelve hours after exposure. [2]
It is also possible for high levels of methanol to be produced by contaminating microbes during traditional ethanol fermentation. The UK Foreign Office advises travellers: "Take care if offered ...

What is methanol? Methanol, a colourless liquid with a faintly sweet pungent smell, completely mixes with water. It’s very similar to ethanol – the pure form of alcohol in alcoholic drinks.
Methanol is a toxic alcohol used in industrial and household products like paint thinners, antifreeze, varnish and photocopier fluid. It is colourless and has a similar smell to ethyl alcohol ...
Pyridine and methanol, [1] each and together, make denatured alcohol poisonous; and denatonium makes it bitter. Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. Because of the diversity of industrial uses for denatured alcohol, hundreds of additives and denaturing methods have been used.
If as little as 10 mL of pure methanol is ingested, for example, it can break down into formic acid, which can cause permanent blindness by destruction of the optic nerve, and 30 mL is potentially fatal, [45] although the median lethal dose is typically 100 mL (3.4 fl oz) (i.e. 1–2 mL/kg body weight of pure methanol [46]).
