Inhalation: Move person into fresh air immediately. Keep at rest. Seek medical attention if symptoms persist. Provide artificial respiration if breathing stops.
Skin Contact: Remove contaminated clothing and wash skin thoroughly with soap and water. Get medical attention for irritation.
Eye Contact: Rinse cautiously with water for at least 15 minutes, lifting eyelids. Remove contact lenses if present and easy. Get prompt medical advice.
Ingestion: Do not induce vomiting. Rinse mouth. Never give anything by mouth to an unconscious person. Seek medical help promptly.
Note to Physician: Treat symptomatically; monitor for respiratory complications and CNS depression.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray (do not use water jet)
Specific Hazards: Releases flammable vapors, vapor/air mixtures may explode far from ignition source, combustion produces toxic gases including carbon monoxide
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing
Special Procedures: Keep containers cool by spraying with water, prevent run-off from fire control from entering environment or sewers
Explosion Data: Vapors likely accumulate in low or confined places; significant risk of flashback
Personal Precautions: Evacuate area, ventilate, eliminate all ignition sources, wear suitable protective equipment
Environmental Precautions: Prevent entry into drains, waterways and soil
Methods for Cleaning Up: Absorb with inert material (sand, earth), collect in appropriate containers for disposal, ventilate area thoroughly
Spill Control: Use non-sparking tools, ground and bond containers
Decontamination: Wash spill site after clean-up
Safe Handling: Use only in well-ventilated places, avoid inhalation or contact with skin and eyes, keep away from heat, sparks, open flames, do not eat, drink or smoke near the material, use explosion-proof equipment
Storage Conditions: Store in tightly closed containers, in cool, dry, well-ventilated areas away from incompatibles like strong oxidizing agents, acids. Segregate from food and drink, ground and bond containers transmitting liquid
Technical Measures: Install emergency showers and eyewash stations nearby
Incompatible Materials: Heat, strong acids, alkalies, oxidizers, chlorine
Special Storage Requirements: Protect containers from damage, regularly inspect storage sites for leaks
Occupational Exposure Limits: ACGIH TLV: 50 ppm (skin), OSHA PEL: 500 ppm
