Skin: May cause skin irritation with pain and stringing, especially when skin is abraded. Inhalation: Solvents may cause respiratory tract irritation, headaches and possible dizziness. Ingestion: May cause respiratory and digestive tract irritation. Chronic: Prolonged and repeated exposure may cause dermatitis, defatting of the skin, liver and kidney damage, and adverse central nervous system effects. Section 4: First Aid Measure Eyes: Remove contact lenses. Flush with water or saline. Get medical aid. Skin: Wash skin with large quantities of soap and water. Get medical aid if symptoms persist. Inhalation: Immediately remove from exposure to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Ingestion: Do not induce vomiting. If conscious, give 1 to 2 glasses of water. Get medical aid. Section 5: Fire Fighting Measures Autoignition Temperature: N/A Flash Point: -20 C -4 F LEL / UEL: N/A Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam. General Information: Will burn if involved in a fire. Flash back along vapor trail is possible. Section 6: Accidental Release Measures Spill Procedure: Remove all sources of ignition.
