Methanol may cause blindness, intoxication, dizziness, coma Emergency Overview: and death. Primary Routes of Exposure:Inhalation, ingestion, contact with skin and eyes. Eye Contact:Causes severe irritation of the eyes. Delayed blindness may occur through atrophy of the optic nerve. Skin Contact:Causes moderate irritation of the skin. Methanol vapor may be irritating to the respiratory tract and cause headache, dizziness, coma, and blindness. Inhalation: Ingestion:Ingestion may cause gastrointestinal distress, blindness, convulsions and coma. Irritating to skin, eyes and respiratory tract, cause nausea and vomiting, intoxication, blindness, convulsions, Acute Health Affects: and coma. Prolonged exposure may damage eyes, kidneys, and liver, and cause permanent blindness. In animal studies Chronic Health Affects: methanol has acted as a mutagen and reproductive effector. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with soap and water. Remove contaminated clothes if necessary. Seek medical Skin Exposure: assistance if irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
