First Aid Measures

Inhalation: Move person to fresh air and keep comfortable, seek medical advice if symptoms like dizziness or coughing develop
Skin contact: Remove contaminated clothing, rinse skin thoroughly with water, wash with soap and water, consult physician if redness or irritation persists
Eye contact: Gently rinse immediately with plenty of water for at least 15 minutes, remove contact lenses if present and easy, obtain medical attention
Ingestion: Rinse mouth, do not induce vomiting, seek medical care, give water to drink only if person is conscious

Fire-Fighting Measures

Suitable extinguishing media: Carbon dioxide, dry chemical powder, water spray, or foam
Unsuitable extinguishing media: Do not use a strong water jet due to risk of hazardous decomposition
Hazards from combustion: Can release toxic fumes including hydrogen fluoride, phosphorus oxides, nitrogen oxides, carbon oxides
Protective equipment: Firefighters need self-contained breathing apparatus and fully protective clothing for significant exposure or confined fires

Accidental Release Measures

Personal precautions: Wear appropriate chemical-resistant gloves, safety goggles, lab coat; ventilate the area
Environmental precautions: Take steps to avoid environmental runoff, prevent entry into drains or waterways
Methods for cleanup: Absorb small spills with inert absorbent (sand, vermiculite), collect in closable containers, dispose according to regulations, wash contaminated area with water and detergent, ventilate area after cleanup

Handling and Storage

Safe handling advice: Use in a well-ventilated area, avoid inhaling vapor or mist, avoid skin and eye contact, keep away from heat sources
Storage requirements: Store in a cool, dry place in tightly sealed containers, protect from direct sunlight, keep away from strong oxidizers or incompatible materials, label storage clearly, maintain access controls for hazardous chemicals

Exposure Controls and Personal Protection

Engineering controls: Work with local exhaust ventilation or fume hood for bulk handling, maintain eye wash and emergency showers nearby
Personal protection: Wear safety glasses or face shield, impermeable gloves, laboratory coat, use a respirator for insufficient ventilation
Workplace exposure limit: No established occupational exposure limits, limit exposure by best laboratory practice

Physical and Chemical Properties

Appearance: Viscous colorless to light yellow liquid
Odor: Mild, non-characteristic
Melting point: 15°C to 25°C (range due to impurities or water content)
Boiling point: Decomposes before boiling
Density: 1.15–1.18 g/cm³
Solubility: Slightly soluble in water, soluble in organic solvents (acetonitrile, methanol, dichloromethane)
Vapor pressure: Negligible at room temperature
pH: Neutral to slightly acidic (depends on solubility in water)

Stability and Reactivity

Chemical stability: Stable under recommended storage and handling conditions
Incompatible materials: Strong oxidizers, strong acids, reducing agents
Hazardous decomposition products: May produce hydrogen fluoride, phosphorus pentafluoride, carbon oxides, toxic fluorinated compounds
Reactivity: Avoid contact with bases and moisture due to risk of hydrolysis and gas formation

Toxicological Information

Likely routes of exposure: Inhalation, skin contact, eye contact, ingestion
Potential health effects: May cause irritation to skin, eyes, and respiratory tract; overexposure can lead to drowsiness, headache, abdominal discomfort
Acute toxicity: Limited animal toxicity data available; estimated oral LD50 > 2000 mg/kg (rat, similar compounds)
Chronic effects: Prolonged exposure may cause dermatitis or respiratory symptoms
Carcinogenicity: No data to classify as carcinogenic
Mutagenicity: Not tested, no evidence found in related substances

Ecological Information

Environmental fate: Persistent in environment; does not readily biodegrade
Aquatic toxicity: Toxic to aquatic organisms, long-term effects in aquatic environments
Mobility: May leach into soil and waters due to solubility
Bioaccumulation potential: Low to moderate, accumulates slowly
Precaution: Prevent spillage and runoff, focus on containment and proper disposal

Disposal Considerations

Waste treatment methods: Dispose through an approved waste chemical disposal contractor
Contaminated packaging: Wash and dispose as chemical waste, never reuse for other purposes
Hazardous waste code: Check local regulations, may be classified under halogenated organic waste
Incineration: Only in facilities with suitable flue gas scrubbing equipment to capture fluorine byproducts

Transport Information

UN number: Not classified under typical UN hazardous categories; check current national transport regulations for latest classification
Transport hazard class: Considered environmentally hazardous substance
Packing group: III (if classified due to aquatic hazard)
Special precautions: Clearly label containers, document as hazardous for aquatic environments, protect against leakage and breakage, keep separate from foodstuffs or animal feed

Regulatory Information

Labeling requirements: Comply with local chemical safety labeling including hazard pictograms, signal words, and precautionary statements
Inventory status: Listed in major chemical inventories where applicable (e.g., TSCA, EINECS, DSL), check current country-specific chemical lists
Environmental regulations: Subject to reporting under pollutant release and transfer registries (PRTR), ensure compliance with local water and waste regulations
Worker protection: Ensure compliance with occupational health and safety guidelines for chemical use, require personnel training before handling
Restrictions: Not subject to international bans but may face local restrictions for environmental risks
