Inhalation: Remove person to fresh air. Seek medical attention if symptoms persist.
Skin Contact: Take off contaminated clothing. Wash with soap and water. Get medical advice if irritation develops.
Eye Contact: Rinse with water for at least 15 minutes, lifting eyelids. Remove contact lenses if present. Ask for medical help.
Ingestion: Do not induce vomiting. Rinse mouth with water. Seek immediate medical attention.
Acute and Delayed Symptoms: May cause central nervous system depression, nausea, dizziness, or headache.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, or water mist.

Protective Equipment for Firefighters: Full protective gear and self-contained breathing apparatus. Cool sealed containers with water spray.
Personal Precautions: Evacuate area if vapor concentration is high. Use protective equipment: gloves, goggles, respirators if needed. Eliminate ignition sources.
Environmental Precautions: Prevent entry into waterways, drains, or sewers. Notify authorities if large amounts escape.
Cleanup Methods: Contain spill with sand, earth, or absorbent materials. Collect residue in tightly sealed containers for disposal. Wash spill area thoroughly.
Handling: Avoid breathing mist, vapor, or spray. Avoid contact with skin and eyes. Use in well-ventilated areas. Do not smoke near product.
Storage: Store in cool, dry, well-ventilated area away from sunlight, sparks, and open flames. Keep containers tightly closed and grounded.
Special Instructions: Store away from acids, oxidizers, and strong bases. Use non-sparking tools.
Exposure Limits: ACGIH TLV: 100 ppm TWA; OSHA PEL: 100 ppm
Engineering Controls: Use mechanical (general or local exhaust) ventilation to control airborne vapors.
Personal Protective Equipment:
Gloves: Chemical-resistant recommended (nitrile, neoprene).
Eye: Safety goggles or full-face shield.
Respiratory: Approved respirators in poorly ventilated areas.
Other: Protective clothing to prevent skin exposure.
