U.S. FDA has warned customers to stop using hand sanitizers containing methanol. Some of the products tested by FDA had 81% & 28% methanol (v/v). Methanol is toxic by ingestion and absorption through skin.

Consumers who have been exposed to hand sanitizer containing methanol should seek immediate treatment, which is critical for potential reversal of toxic effects of methanol poisoning. Substantial methanol exposure can result in nausea, vomiting, headache, blurred vision, permanent blindness, seizures, coma, permanent damage to the nervous system or death. Although all persons using these products on their hands are at risk, young children who accidently ingest these products and adolescents and adults who drink these products as an alcohol (ethanol) substitute, are most at risk for methanol poisoning.

MFAG, Medical First Aid Guide, (supplement of IMDG Code) table 19 deals with methanol and ethylene glycol poisoning.
