Impurities: Trace amounts of cresols and cumene possible depending on supplier and production
Other Components: None reported as significant at levels affecting classification
Eye Contact: Immediately rinse with plenty of lukewarm water for at least 15 minutes, lifting upper and lower eyelids occasionally, and seek medical attention
Skin Contact: Remove contaminated clothing, flush skin with copious amounts of water, wash with soap, consult a physician if irritation develops
Inhalation: Move person to fresh air, assist breathing if needed, call a physician
Ingestion: Rinse mouth thoroughly, do NOT induce vomiting unless advised by medical personnel, call a poison center or doctor right away
Most Important Symptoms: Burning sensation, redness, dermatitis, respiratory distress if vapor inhaled
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide for small fires. Water spray may be used to cool containers
Special Exposure Hazards: Vapor may travel back to ignition source; produces toxic fumes of CO and CO2 when burned
Firefighter Protection: Wear self-contained breathing apparatus and full protective gear
