Impurities: Trace levels of related chloroformates and hydrochloric acid possible
Inhalation: Move the affected person to fresh air immediately, supply oxygen if breathing difficulty occurs, seek medical attention
Skin Contact: Remove contaminated clothing, flush skin liberally with water and soap, monitor for burns, seek a doctor
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, hold eyelids open and seek urgent medical care
Ingestion: Rinse mouth, do not induce vomiting, get prompt medical help
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or foam; avoid water jets
Hazardous Combustion Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide
Firefighter Protection: Wear full protective gear and a self-contained breathing apparatus
Explosion Risk: Vapors may form explosive mixtures with air
Personal Precautions: Evacuate area, use chemical splash goggles, nitrile gloves, chemical-resistant clothing
Environmental Precautions: Prevent spills from entering drains, waterways, or soil
Cleanup Methods: Absorb with inert material such as sand, place waste in sealed containers for disposal, ventilate area thoroughly
Handling: Keep containers tightly sealed, operate in fume hoods or well-ventilated areas, avoid direct contact, never mix with water or alcohols casually
Storage: Store away from strong bases, water, oxidizers, acids, and sources of ignition, use corrosion-resistant containers, maintain at controlled temperature
Engineering Controls: Chemical fume hoods, local exhaust ventilation
Personal Protective Equipment: Chemical splash goggles, impervious gloves, lab coat, respiratory protection for high vapor concentrations
Exposure Limits: No specific OSHA or ACGIH limits, minimize exposure as much as possible
Physical State: Liquid
