Moisture will produce ethanol vapor which may Emergency Overview: cause drowsiness. Primary Routes of Exposure:Inhalation, ingestion, contact with skin and eyes. Eye Contact:The dust and ethanol hydrolysis product may cause moderate irritation of the eyes. Skin Contact:Solid may cause mild irritation of the skin. Dust may cause moderate irritation to the upper respiratory tract. Ethanol vapor may cause dizziness and Inhalation: drowsiness Ingestion:Ingestion may cause gastrointestinal distress, nausea, vomiting and headache. May be irritating to skin, eyes and respiratory tract. Exposure may cause impairment of coordination and Acute Health Affects: reaction time. No data is available for this product. Prolonged exposure to ethanol vapors may be harmful to nerves and Chronic Health Affects: liver. 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 water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in Inhalation: breathing, coughing, wheezing or pain. In such cases seek immediate medical assistance.
