Inhalation: Remove person to fresh air. Rest in a position comfortable for breathing. Seek medical attention if symptoms persist.
Skin Contact: Take off contaminated clothing. Rinse skin thoroughly with water and soap. Seek medical help for irritation or persistent reddening.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Continue rinsing, get medical advice if irritation develops.
Ingestion: Do not induce vomiting. Rinse mouth. Never give anything by mouth to an unconscious person. Seek medical attention immediately.
Most Important Symptoms: Drowsiness, dizziness, headache, nausea, respiratory tract irritation, dermatitis
Immediate Medical Attention: Advised for any exposure above threshold limit or for persistent adverse effects.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, water spray (fog)
Fire Hazards: Extremely flammable liquid and vapor. Vapors can travel to ignition source and flash back. Containers may explode in heat of fire.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective suit.
Special Procedures: Cool containers with water jet to prevent pressure buildup. Avoid run-off to sewers and waterways.
Products of Combustion: Carbon monoxide, carbon dioxide, possible hazardous hydrocarbon fragments.
Personal Precautions: Evacuate non-essential personnel. Isolate hazard area. Remove all ignition sources and ventilate affected area.
Protective Equipment: Wear gloves, protective clothing, goggles, and respirator. Prevent skin and eye contact.
Spill Containment: Stop leak if without risk. Prevent from entering drains, sewers, basements.
Cleanup Methods: Absorb liquid in sand, earth, or inert absorbent. Collect in suitable closed containers for disposal. Ventilate area thoroughly.
Environmental Precautions: Avoid release to the environment. Inform responsible authorities of large spills.
Safe Handling: Use outdoors or in well-ventilated area. Avoid prolonged or repeated skin contact. Avoid inhaling vapor or mist. Ground and bond containers before transfer.
Hygiene Practices: Wash hands thoroughly after use. Remove contaminated clothing and wash before reuse.
Storage Requirements: Store in tightly closed, clearly labeled container, in cool, dry, well-ventilated place. Keep away from heat, spark, open flame, and incompatible materials.
