Purity: >98%
Impurities: Moisture content, low-level organic and inorganic byproducts
Inhalation: Remove person to fresh air. Seek medical attention if symptoms persist.
Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing. Medical advice needed if irritation occurs.
Eye Contact: Rinse with plenty of water for at least 15 minutes. Remove contact lenses if present. Seek medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Get immediate medical attention.
Symptoms: Coughing, sore throat, redness or blisters on skin, eye watering, abdominal discomfort after swallowing.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam
Unsuitable Media: Avoid water stream if possible as it may spread chemical
Specific Hazards: Combustion can release toxic gases such as hydrogen fluoride, phosphorus oxides, nitrogen oxides
Protective Equipment: Wear self-contained breathing apparatus, full protective gear
Advice for Firefighters: Stay upwind, avoid inhalation of exhaust. Contain runoff water to prevent environmental contamination.
Personal Precautions: Wear gloves, protective glasses, appropriate mask; restrict unnecessary access; ventilate clouded areas
Environmental Precautions: Prevent entry into sewer and waterways; notify authorities if harmful discharge occurs
Cleanup Methods: Absorb with inert material (sand, earth, vermiculite), collect in proper waste container, wash spill area with water and detergent
Decontamination: Wash tools and hands thoroughly after cleanup
Handling: Use in fume hood, avoid skin and eye contact, avoid inhaling vapor or dust, keep away from incompatible materials (e.g., strong oxidizers, acids, bases)
Storage: Store tightly sealed in cool, dry, ventilated area; keep container upright and labeled; prevent moisture exposure; keep away from sources of ignition
Incompatibilities: Moist air, strong oxidizing agents, acids, alkali
Engineering Controls: Work with local exhaust ventilation; use safety shower and eyewash station nearby
OELs: No established occupational exposure limit values, control exposure as low as possible
Personal Protective Equipment: Nitrile gloves, lab coat, safety goggles, face shield if splashes are likely
Respiratory Protection: NIOSH-approved mask for dust/mist/vapors if ventilation is inadequate
Hygiene Measures: Wash hands before eating, drinking, or smoking; remove contaminated clothing after use
Appearance: Colorless to pale-yellow viscous liquid
Odor: None or faint organic odor
Melting Point: -20 to -15°C (varies by purity)
Boiling Point: Not well defined, decomposes above 350°C
Density: Approximately 1.3–1.4 g/cm3 at 25°C
Solubility: Soluble in organic solvents; little to no solubility in water
Vapor Pressure: Very low at room temperature
pH: Not applicable (non-aqueous)
Partition Coefficient: log Pow not determined
Decomposition Temperature: Decomposes above 350°C
Chemical Stability: Stable at room temperature under recommended storage
Possibility of Hazardous Reactions: May react violently with strong oxidizers, strong acids or bases
Conditions to Avoid: Moisture, heat, open flames, incompatible substances
Decomposition Products: Hydrogen fluoride, phosphorus oxides, nitrogen oxides, other harmful gases
Polymerization: Not expected under normal methods of use and storage
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Harmful if swallowed, irritating to mucous membranes
Skin Sensitization: Repeated contact causes dryness and chapping
Eye Effects: Causes irritation, tearing, and redness
Long-Term Effects: No comprehensive studies on chronic effects, best practice is to minimize all unnecessary exposures
Carcinogenicity: No data indicating carcinogenic effects
Mutagenicity / Reproductive toxicity: Not established due to limited available research
Additional Toxicological Data: Data gaps remain for many chronic endpoints; handling precautions should reflect this uncertainty.
Ecotoxicity: May be harmful to aquatic life due to fluorinated anion, limited direct data available
Environmental Fate: Not readily biodegradable, potential persistence and bioaccumulation depend on local environmental conditions
Mobility: Low mobility in soil; mostly remains where released unless in contact with water
Degradation: Hydrolysis leads to release of fluoride ions under certain conditions
Bioaccumulation: Unknown, but structurally related ionic liquids may accumulate in some species
Remarks: No threshold values set for drinking water exposure or soil contamination; best environmental management keeps it contained and out of waste streams.
Waste Treatment Methods: Collect in chemically compatible containers, label clearly, and store until picked up by a licensed hazardous waste contractor
Disposal of Product: Incinerate at high temperature in chemical incinerator equipped for scrubbing hydrogen fluoride emissions
Disposal of Packaging: Clean thoroughly before recycling or disposal; dispose by similar controls as for chemical product
Sewer Disposal: Avoid, can damage waterways and sewage treatment systems
