Suitable Extinguishing Media: Use dry chemical powder, CO2, alcohol-resistant foam, water spray (not direct stream)
Specific Hazards: Vapors can form explosive mixtures with air, combustion releases toxic fumes including hydrogen chloride, phosgene, and carbon monoxide
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing
Special Information: Contain run-off to prevent contamination of water courses, cool fire-exposed containers with water
Personal Precautions: Evacuate area, ventilate, avoid breathing vapors, prevent skin and eye contact, use personal protective equipment
Environmental Precautions: Prevent leak or spill from entering drains, surface water, or soil
Containment: Stop leak if safe to do so, dike large spills
Cleanup Methods: Absorb with non-combustible absorbent (sand, earth, vermiculite), collect in containers for disposal, ventilate area, decontaminate with alkaline detergent solution
Handling: Use only in chemical fume hood or well-ventilated location, keep away from heat, sparks, open flames, and static discharge, avoid breathing vapor or mist, avoid contact with skin, eyes, and clothing
Storage: Keep in tightly closed containers, store in cool, dry, well-ventilated area resistant to acid vapors, segregate from strong bases, oxidizers, and water, label containers clearly
