(N/A) Denatured alcohol is ethanol $\left( C _{2} H _{5} OH \right)$ mixed with methanol $\left( CH _{3} OH \right)$.
Effects: When a person consumes denatured alcohol,methanol is oxidized in the body to methanal $\left( HCHO \right)$ and subsequently to methanoic acid $\left( HCOOH \right)$. This process causes severe toxicity,leading to blindness and potentially death.
Remedies: The treatment for methanol poisoning involves the intravenous administration of diluted ethanol. Ethanol acts as a competitive inhibitor for the enzyme responsible for the oxidation of methanol. This allows the body time to excrete the methanol through the kidneys,thereby preventing the formation of toxic methanoic acid and saving the patient.
