Is Methanol Toxic When Burned? No, while methanol, both as a liquid and as a gas, is toxic, the byproducts of burned methanol are carbon dioxide and water and neither of these is toxic (though carbon dioxide is a potential asphyxiation hazard).

What happens if you burn methanol?

Like many hydrocarbon derivatives, methanol undergoes combustion (see simulation at bottom of page) when combined with heat and oxygen. This reaction releases energy, carbon dioxide, and water.

Is methanol safe to burn indoors?

Very clean combustion with negligible emissions and no soot. Can safely be used indoors; eliminates Household Air Pollution (HAP) Heat available instantly after ignition.
