Inhalation: Move person to fresh air immediately, seek urgent medical attention, provide oxygen if breathing is difficult.
Skin contact: Remove contaminated clothing, wash affected skin with soap and water, call a physician if irritation or symptoms occur.
Eye contact: Rinse with copious amounts of clean water for at least 15 minutes; obtain prompt medical evaluation.
Ingestion: Do not induce vomiting, rinse mouth, seek immediate medical attention. Activated charcoal may be recommended in some cases.
Medical Guidance: Treat symptomatically, monitor for delayed effects on the nervous system and liver.
Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam; avoid water stream that may spread contamination.
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Hazardous Combustion Products: Hydrogen chloride, phosgene, toxic fumes; avoid inhaling decomposition gases.
Fire and Explosion Hazards: Not flammable under standard conditions, can emit corrosive, toxic gases if heated.
Precautions: Isolate area, prevent firefighting water from entering drains or waterways.
Personal Precautions: Wear protective clothing, gloves, boots, and eye/face protection; avoid breathing dust or vapors.
Environmental Precautions: Prevent material from entering soil, sewers, waterways, or confined areas; contain with barriers.
Cleaning Methods: Collect spillage using non-sparking tools and place in labeled, sealed containers for disposal; avoid creating dust.
Decontamination: Wash contaminated area thoroughly with water and detergent, ventilate the area.
Reporting: Notify local environmental and health authorities per regulations.
Handling: Use in controlled, well-ventilated areas; minimize exposure; avoid creating dust or aerosols; do not eat, drink, or smoke in work areas.
Storage: Keep container tightly closed, store in a cool, dry, well-ventilated place away from incompatible materials, sources of ignition, and out of reach of unauthorized personnel; use secure, labeled storage compatible with hazardous materials management.
Incompatibilities: Strong acids, alkalis, oxidizers; incompatible with most reactive substances.
Occupational Exposure Limits: ACGIH TLV: 0.001 mg/m³ (TWA), OSHA PEL: 0.1 mg/m³ (TWA)—refer to most current regulatory limits.
Engineering Controls: Use local exhaust ventilation, process enclosures, or other engineering controls to control airborne levels.
Personal Protective Equipment: Approved respirators (full-face or half-mask as appropriate), chemical-resistant gloves, protective clothing, safety goggles or face shield.
Hygiene Measures: Wash hands thoroughly after handling, remove and wash contaminated clothing, provide eyewash stations, avoid accidental exposure.
Appearance: White crystalline solid (may discolor on prolonged exposure to air or light).
Odor: Odorless.
Boiling Point: Decomposes before boiling.

pH: Not applicable (insoluble in water).
Flash Point: Not applicable, not combustible.
Partition Coefficient (Log Kow): 5.41 (high potential for bioaccumulation).
Chemical Stability: Stable under recommended storage conditions.
Conditions to Avoid: Heat, open flame, exposure to light and air over extended periods, moisture.
Hazardous Reactions: Reacts with strong acids, bases, or oxidizers; may decompose violently at high temperatures.
Hazardous Decomposition Products: Releases hydrogen chloride, phosgene, chlorine gas, and other toxic compounds upon thermal decomposition.
Acute Toxicity: LD50 (oral, rat): 95 mg/kg; highly toxic by ingestion or inhalation.
Chronic Effects: Causes liver enlargement, neurological disorders, tremors, weight loss, reproductive effects.
Carcinogenicity: Classified as possibly carcinogenic to humans by IARC (Group 2B); listed by EPA as a probable human carcinogen.
Reproductive Toxicity: Animal studies show reduced fertility and reproductive effects.
Routes of Exposure: Skin, eyes, inhalation, ingestion.
Symptoms of Exposure: Headache, nausea, fatigue, tremors, dermatitis, liver toxicity, neuropsychiatric effects.
Other Data: Bioaccumulates in human tissue, especially liver and fatty tissue; can cross placenta and enter breast milk.
Biodegradability: Highly persistent in soil, sediment, and aquatic environments.
Bioaccumulation Potential: High (bioconcentration factor up to 13,000 in aquatic organisms).
Toxicity to Aquatic Life: Very toxic to fish, invertebrates, and aquatic plants.
Mobility in Soil: Low volatility, binds strongly to soil particles; risk of leaching to groundwater in sandy or porous soils.
Long-Term Environmental Impact: Persists for decades, disrupts ecosystems, and enters food webs.
Other concerns: Detected in surface and groundwater long after use stopped; bioaccumulates up the food chain from plankton to humans.
Waste Handling: Treat as hazardous chemical waste; avoid incineration due to production of toxic gases.
Disposal Methods: Incinerate in properly equipped facility with advanced emission controls, or treat at approved chemical waste landfill per environmental regulations.
Contaminated Packaging: Triple-rinse containers, disable for reuse, and dispose of as hazardous waste.
Precautions: Do not allow disposal material to contaminate soil, water, or drains; consult local, regional, and national regulations.
