Ingestion: Rinse mouth, do not induce vomiting, get medical attention right away, never give anything by mouth if unconscious
Notes for Physicians: Treat as strong acid exposure, support vital functions, monitor for delayed pulmonary effects
Suitable Extinguishing Agents: Use dry chemical, CO2, or foam, never use water directly on container
Hazardous Combustion Products: Releases toxic fumes of HCl, phosgene, and carbon oxides
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Special Procedures: Avoid inhaling decomposition products, use copious water spray to cool containers, prevent runoff from reaching drains or waterways
Personal Precautions: Evacuate all unprotected personnel, ventilate area, use appropriate PPE including respirator and chemical goggles
Environmental Protections: Prevent spillage from entering drains or watercourses, avoid soil contamination
Containment & Cleanup: Absorb with inert dry material (sand, vermiculite), place in chemical waste container, neutralize residue, ventilate area until safe, dispose according to local regulations
Safe Handling Advice: Handle inside chemical fume hood, avoid all contact with skin, eyes, and clothing, ensure emergency showers and eyewash stations nearby
Storage Conditions: Store in tightly closed containers away from heat and moisture, keep away from bases, alcohols, amines, strong oxidizing agents
Storage Temperature: Keep at 2–8°C for best stability,
Other Instructions: Keep separate from incompatible materials, label all containers clearly
Engineering Controls: Strong ventilation, fume hoods, negative pressure enclosures where possible
Exposure Limits: No specific OSHA or ACGIH TLVs assigned, minimize exposure as much as possible
Respiratory Protection: Approved cartridge respirators for acid gases or full-face supplied air for large spills
Skin Protection: Impervious chemical-resistant gloves (nitrile, neoprene) and full-length lab coats or chemical suits
Eye/Face Protection: Tightly fitting goggles and face shield
Other Protection: Safety shoes, chemical apron, avoid wearing contact lenses in contaminated areas
Appearance: Clear to pale yellow liquid
Odor: Sharp, irritating, pungent
Boiling Point: ~211 °C
Melting Point: Not well defined, below 0°C
Flash Point: Data not available; treat as non-flammable but handle with caution
Vapor Pressure: Low, increases with temperature
Solubility: Reacts violently with water, forms HCl
Density: Approx. 1.2 g/cm³
pH: Acidic in solution, but reacts with water
Other Properties: Corrosive to metals and tissue, releases corrosive vapors on contact with moisture in air
Chemical Stability: Stable under recommended storage, decomposes in moisture and at elevated temperatures
Incompatible Materials: Water, strong bases, alcohols, amines, oxidants
Hazardous Reactions: Violent hydrolysis, liberates HCl gas and heat
Decomposition Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide
Polymerization: No significant risk under normal conditions
Acute Toxicity: Harmful by inhalation, ingestion, skin contact; LD50 not fully established
Corrosive Effects: Causes burns to skin, eyes, and mucous membranes
Chronic Effects: Repeated exposure may cause dermatitis or respiratory damage
Sensitization: No data available on sensitization
Carcinogenicity/Mutagenicity: No comprehensive assessments, not classified as a human carcinogen by IARC, NTP, or OSHA
Symptoms of Overexposure: Burning pain, coughing, labored breathing, severe irritation, delayed lung edema possible
Ecotoxicity: Harmful to aquatic life due to acidity of hydrolysis products
Environmental Fate: Hydrolyzes rapidly; forms hydrochloric acid, alters pH in natural waters
Persistence and Degradability: Not persistent due to hydrolysis, but acidic byproducts can harm local environments
Bioaccumulation Potential: Not expected to bioaccumulate
Mobility in Soil: Likely to degrade in contact with moisture, but acidic runoff may mobilize heavy metals
Disposal Method: Incinerate at chemical waste facility with permit for corrosive halogenated organics
Container Handling: Triple rinse, neutralize residues, puncture and dispose as hazardous waste
Never Discharge: To drains, waterways, or typical landfill sites
Local Regulations: Follow national and local regulations for hazardous waste disposal
Special Precautions: Consult environmental agency if unsure about disposal options
