Inhalation: Move to fresh air. Keep at rest. Seek medical attention for symptoms like coughing, shortness of breath, dizziness.
Skin Contact: Remove contaminated clothing; wash skin with running water and mild soap for several minutes. Obtain medical advice for persistent irritation.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Seek immediate medical attention if irritation or pain develops.
Ingestion: Rinse mouth with water. Do not induce vomiting. Call a poison information center or doctor. Maintain airway and monitor for trouble breathing.
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (do not use water jet directly on liquid).
Unsuitable Media: Direct, high-pressure water stream may spread fire.
Specific Hazards: Vapors may form explosive mixture with air. May give off toxic fumes like carbon oxides and nitrogen oxides during combustion.
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus.
Special Procedures: Remove containers from fire area if safe. Cool closed containers with water spray. Control runoff to avoid environmental contamination.
Personal Precautions: Use proper protective equipment including gloves and chemical splash goggles. Evacuate unnecessary personnel. Ensure adequate ventilation.
Environmental Precautions: Prevent entry into watercourses, drains, or soil. Alert authorities if product has entered environment.
Methods for Cleanup: Contain spill using non-combustible absorbent (sand, earth, vermiculite). Scoop into labeled drums for disposal. Clean contaminated area thoroughly.
Other Precautions: Remove ignition sources and ventilate area during cleanup. Wash hands after handling material and before eating or drinking.
Handling: Use in well-ventilated locations. Avoid inhaling vapors or contact with skin and eyes. Ground containers and outlets when transferring to prevent static spark ignition.
Storage: Store in tightly closed containers, away from incompatible substances like strong acids and oxidizers. Keep in a cool, dry, well-ventilated place. Mark clearly with chemical identification and hazard information.
Special Considerations: Keep away from food and drink. Do not smoke near material. Practice good industrial hygiene, including regular washing of hands and clothing.
Engineering Controls: Local exhaust or ventilation systems for vapor removal. Maintain airborne levels below recommended limits.
Exposure Limits: No specific ACGIH or OSHA limits, but general organic vapor standards apply.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or PVC); safety goggles or face shield; lab coats; use respirators for high vapor levels or spills.
Hygiene Measures: Do not eat, drink, or smoke in work areas. Wash hands after contact. Remove contaminated clothing promptly. Clean up spills immediately.
