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]
Hazard statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). They are intended to form a set of standardized phrases about the hazards of chemical substances and mixtures that can be translated into different languages.
The GHS includes directions for application of the hazard communication elements on the label. In particular, it specifies for each hazard, and for each class within the hazard, what signal word, pictogram, and hazard statement should be used. The GHS hazard pictograms, signal words and hazard statements should be located together on the label.
Precautionary statements are one of the key elements for the labelling of containers under the GHS, along with: [4] an identification of the product; one or more hazard pictograms (where necessary) a signal word – either Danger or Warning – where necessary; hazard statements, indicating the nature and degree of the risks posed by the product
Unlike ethanol, however, methanol is toxic to humans and is commonly used as a solvent in industrial processes, a precursor for producing formaldehyde and an ingredient in products like antifreeze ...
Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard. Note: The asterisks are replaced by the class number and compatibility code
Methanol is commonly used both because its boiling point is close to that of ethanol and because it is toxic. Another typical denaturant is pyridine. Often the denatured alcohol is dyed with methyl violet. [8] There are several grades of denatured alcohol, but in general the denaturants used are similar.
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol, with the chemical formula C H 3 OH (a methyl group linked to a hydroxyl group, often abbreviated as MeOH).
