Inhalation: Move exposed person to fresh air; seek medical attention if symptoms develop such as coughing, dizziness, or breathing difficulties
Skin Contact: Remove contaminated clothing; gently wash affected areas with plenty of soap and water; obtain medical attention for ongoing irritation
Eye Contact: Rinse cautiously with water for 15 minutes, keeping eyelids open; do not rub eyes; call a physician without delay for persistent pain or redness
Ingestion: Rinse mouth with water; do not induce vomiting unless advised by a healthcare provider; contact poison control immediately
Suitable Extinguishing Media: Foam, dry chemical powder, CO2, water spray
Unsuitable Media: Water jets may spread burning liquid
Specific Hazards Arising: Combustion may release hydrogen chloride, chlorine, and carbon oxides
Protective Equipment: Full protective gear, self-contained breathing apparatus
Other Instructions: Approach fire from upwind; prevent run-off from entering water courses
Personal Precautions: Evacuate unnecessary personnel; use chemical splash goggles, impervious gloves, and suitable respiratory protection
Environmental Precautions: Prevent spillage from entering soil, sewers, or waterways; alert relevant environmental authorities for large releases
Spill Cleanup Methods: Absorb liquid with inert material such as sand or earth; collect material into sealable containers for proper disposal; ventilate area thoroughly after cleanup
Decontamination: Wash spill site with detergent and water after material removal
Safe Handling Guidelines: Use only in well-ventilated spaces; avoid contact with eyes and skin; do not inhale vapors or spray mist; use proper lifting techniques for larger containers
Storage Instructions: Store in cool, dry, well-ventilated locations; keep containers tightly closed and away from oxidizing agents; segregate from food and drink supplies
Packaging Materials: Store in HDPE, glass, or stainless steel containers that prevent interaction with chlorinated organics
Engineering Controls: Local exhaust ventilation or chemical fume hoods to reduce airborne concentrations
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles with side shields, lab coats or chemical aprons, and suitable respiratory protection for high vapor concentrations
Exposure Limits: No established OSHA or ACGIH limits; minimize exposure as principle
Hygiene Measures: Remove contaminated clothing and wash thoroughly before breaks and at end of shift; maintain good personal hygiene practices
Appearance: Colorless to pale yellow oily liquid
Odor: Mild, waxy, characteristic
Boiling Point: 325-330°C
Melting Point: 13-15°C
Flash Point: ~160°C (closed cup)
Auto-Ignition Temperature: No data
Solubility in Water: Practically insoluble
Solubility in Other Solvents: Soluble in benzene, chloroform, ether
Density: 0.85-0.87 g/cm3 at 20°C
Vapor Pressure: <0.01 mmHg at 25°C
Partition Coefficient (log Kow): Estimated >6
Chemical Stability: Stable under specified storage conditions
Reactivity: May react with strong bases, strong oxidizers, and strong reducing agents
Hazardous Reactions: Contact with water or moisture may produce hydrogen chloride gas
Hazardous Decomposition Products: Hydrogen chloride, phosgene, and carbon oxides when combusted
Conditions to Avoid: Excessive heat, direct sunlight, humidity, open flames
Acute Toxicity: Low toxicity by dermal route; moderate toxicity via ingestion and inhalation
Skin Corrosion/Irritation: Causes transient redness and irritation; prolonged contact increases severity
Eye Damage/Irritation: Exposure causes irritation, tearing, redness; damage risk escalates with concentration
Respiratory Sensitization: Inhalation of vapor or mist can provoke coughing, sore throat, headache
Chronic Effects: Repeated contact may lead to dermatitis or increased skin sensitivity
Carcinogenicity: No data from animal or human studies
Mutagenicity: Not listed by NTP, IARC, or OSHA
Specific Target Organ Toxicity: Not classified for repeated exposure
Aquatic Toxicity: Expected to be hazardous to aquatic organisms; large spills may impose additional damage by surfactant action
Persistence/Degradability: Not readily biodegradable; strong tendency to bioaccumulate due to high log Kow
Mobility in Soil: Low mobility because of very low water solubility
Bioaccumulation Potential: High, due to lipophilicity; may concentrate in aquatic organism tissue
Other Ecological Effects: Long-term effects to aquatic life possible from chronic exposure or repeated discharges
Disposal Methods: Deliver to licensed hazardous waste contractor for incineration under controlled conditions; never dispose via sewage system or regular landfill
Contaminated Packaging: Empty containers should be triple-rinsed and treated as hazardous; comply with local, regional, and national regulations on disposal and recycling
Special Precautions: Do not attempt to neutralize or chemically treat the material without professional oversight; take care to prevent environmental contamination during storage, transport, or disposal activities
