Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (do not use direct water jet)
Special Hazards: Combustion may generate toxic and corrosive fumes, including hydrogen fluoride, boron oxides, phosphorus oxides, and other unidentified organic compounds
Protective Equipment: Firefighters require self-contained breathing apparatus and protective clothing due to risk of corrosive and toxic gases
Specific Methods: Move containers away from affected area if possible and safe, cool fire-exposed containers with water spray, prevent runoff entering water sources
Hazardous Decomposition: Tetrafluoroborate salts decompose under intense heat, producing hydrogen fluoride and boron trifluoride vapors
Personal Precautions: Use adequate ventilation, wear gloves, chemical splash goggles, and suitable protective clothing to prevent direct contact
Environmental Precautions: Keep material out of drains, surface water, and soil, contain spillage to avoid environmental contamination
Methods for Cleaning Up: Absorb spillage with inert absorbent material (sand, earth, vermiculite), sweep or scoop into suitable containers for disposal, wash spill site with water and detergent
Prevent Further Leaks: Secure containers, isolate spill area, avoid generating dust or aerosols
Disposal: Dispose of collected material in accordance with local regulations
Handling Recommendations: Use with local exhaust ventilation, avoid breathing vapors or dust, avoid skin and eye contact, wash hands thoroughly after handling, keep work area clean and free of unnecessary materials
Safe Storage Conditions: Store in tightly closed, clearly labeled containers in a dry, cool, and well-ventilated area, protect from moisture and direct sunlight, segregate from incompatible materials such as strong oxidizers, acids, and alkali metals
Storage Temperature: Ambient or as specified by product integrity requirements
Special Provisions: Keep away from food, drink, and animal feed, store only in original packaging or containers compatible with strong ionic materials
Occupational Exposure Limits: No established regulatory limits for this compound, avoid exposure as much as possible
Engineering Controls: Local exhaust ventilation, eye wash stations, safety showers
Personal Protective Equipment:
Gloves (nitrile or polyvinyl chloride recommended), chemical splash goggles or face shield, lab coat or apron, impermeable closed-toe shoes
Respiratory Protection: Use approved respirators if ventilation is insufficient or exposure limits may be exceeded
Hygiene Measures: Wash hands, arms, and face after handling, change contaminated clothing, do not eat, drink, or smoke during use

Conditions to Avoid: Avoid heat, sparks, open flames, contact with moisture or strong oxidizing/reducing agents
Incompatible Materials: Strong oxidizers, strong acids, alkali metals, moisture-sensitive chemicals, sources of ignition
Hazardous Decomposition Products: Decomposition can produce toxic and corrosive vapors including hydrogen fluoride, boron trifluoride, and phosphorus oxides
Reactivity: Non-reactive with most materials under normal conditions; risk of hazardous reactions with incompatible substances
Acute Toxicity: Oral and dermal toxicity data limited but considered harmful; animal studies show LD50 (oral, rat) estimated between 300–2000 mg/kg
Skin Corrosion/Irritation: Product may cause irritation and redness, risk of dermatitis from repeated exposure
Serious Eye Damage/Irritation: Contact with eyes results in irritation, watering, risk of conjunctivitis upon exposure
Respiratory Effects: Inhalation of vapors, mists or dust may cause irritation to nose, throat, and lungs
Chronic Effects: Repeated or prolonged skin contact may cause sensitivity or dermatitis
Carcinogenicity: No data available, not listed by IARC, NTP, or OSHA as a carcinogen
Mutagenicity: No evidence from available data
Reproductive Toxicity: No studies in humans or animals demonstrate reproductive harm
Other Information: Avoid repeated exposure, and take precautionary measures due to lack of full toxicological profile
Ecotoxicity: Limited studies suggest moderate acute hazard to aquatic life; tetrafluoroborate ions can be toxic at higher concentrations
Persistence/Degradability: Product is persistent in environment, ion pairs do not readily biodegrade; ultimate fate depends on environmental conditions
Bioaccumulative Potential: Low bioaccumulation expected, large ionic molecule unlikely to pass biological membranes efficiently
Mobility in Soil: Expected to have moderate persistence in soils, leaches slowly depending on ionic strength of soil matrix
Other Adverse Effects: Avoid direct release to water bodies, municipal sewers, or natural environments to reduce ecological impact
Additional Notes: Prolonged environmental exposure may contribute to altered microbial or chemical balances in affected habitats
