First Aid Measures

Inhalation: Move affected person into fresh air immediately, keep at rest, provide oxygen if breathing is difficult, seek medical attention promptly
Skin Contact: Remove contaminated clothing, rinse skin with soap and plenty of water for at least 15 minutes, call a physician if irritation persists
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical advice if irritation develops
Ingestion: Rinse mouth with water, do not induce vomiting, never give anything by mouth to an unconscious person, seek medical attention as soon as possible
Self-Protection for First Aiders: Wear suitable protective equipment, avoid exposure by inhalation or skin contact

Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide, water spray (not direct stream)
Hazards: Vapors may form explosive mixtures with air, dense vapor may travel at ground level
Hazardous Combustion Products: Hydrogen chloride, carbon monoxide, phosgene, chlorine gases
Fire-Fighter Protection: Wear self-contained breathing apparatus and protective clothing, avoid inhaling combustion products
Advice: Remove containers from area if safe, use water to keep fire-exposed containers cool

Accidental Release Measures

Personal Precautions: Ventilate area, avoid breathing vapors, prevent skin and eye contact, use appropriate PPE (gloves, goggles, respirator)
Environmental Precautions: Stop leak if safe, prevent entry into sewers, watercourses, or soil, notify authorities for large spills
Cleanup Methods: Contain spill with sand or inert absorbent, place in chemical waste container for disposal, wash area thoroughly after pickup

Handling and Storage

Safe Handling: Limit vapors, only use with proper exhaust ventilation, avoid sources of ignition, ground/bond container and receiving equipment, avoid unnecessary exposure
Storage Conditions: Store tightly closed in cool, dry, well-ventilated area, protect from sunlight and incompatible materials, keep away from oxidizing agents and acids

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limits established in most jurisdictions; use precautionary exposure strategies
Engineering Controls: Fume hood or local exhaust ventilation, eyewash stations, emergency showers
Personal Protection: Chemical-resistant gloves, safety goggles or face shield, laboratory coat or coveralls, respiratory protection if ventilation is inadequate
Hygiene Measures: Avoid eating, drinking, or smoking in work area, wash hands and face after handling
Environmental Controls: Prevent discharge into drains, use pollution control measures if required
