Eye Contact: Rinse cautiously with water for at least 15 minutes, remove contact lenses if possible, contact a physician immediately
Ingestion: Rinse mouth, do not induce vomiting, get medical attention; never give anything by mouth to an unconscious person
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide
Specific Hazards: Releases hazardous fumes of nitrogen oxides, carbon oxides, hydrogen chloride on combustion
Protective Equipment: Firefighters should wear self-contained breathing apparatus, full protective gear
Advice for Firefighters: Fight fire from a safe distance, avoid breathing fumes, contain run-off to prevent entry into water courses
Personal Precautions: Wear chemical-resistant gloves, goggles, and protective clothing
Environmental Precautions: Prevent entry into rivers, sewers or water sources, notify authorities in case of large spills
Methods for Cleanup: Absorb with inert material (sand, earth), sweep up, place in suitable labeled containers for disposal, ventilate affected area
Spill Response: Use non-sparking tools, wash spill site after material pick-up is complete
Handling: Avoid breathing vapors or mist, prevent contact with skin and eyes, do not eat, drink or smoke in work areas, wash hands after handling
Storage: Store in tightly closed containers, keep in a dry and well-ventilated place, avoid storing near acids and oxidizers
Storage Temperature: Store above freezing but below 30°C to maintain product stability, keep out of direct sunlight
Special Considerations: Segregate from foodstuffs and incompatible materials, ensure secondary containment for bulk storage
Workplace Exposure Limits: No established occupational exposure limits
Engineering Controls: Use local exhaust ventilation to minimize exposure
Personal Protective Equipment: Wear approved chemical-resistant gloves, safety goggles or face shield, lab coat or apron, use respiratory protection for aerosol/mist formation
Hygiene Measures: Change clothes if contaminated, launder work clothing before reuse, maintain clean work environment
