Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, dry chemical, foam or carbon dioxide
Unsuitable Extinguishing Media: Avoid high-pressure water jets
Specific Hazards: Decomposition may produce toxic gases including hydrogen fluoride, boron oxides, nitrogen oxides
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing
Firefighting Instructions: Move containers from area if possible, cool exposed containers with water, limit exposure to runoff

Accidental Release Measures

Personal Precautions: Evacuate area, use adequate ventilation, avoid breathing dust, wear appropriate personal protective equipment including gloves and goggles
Environmental Precautions: Prevent product from entering drains, sewers, or waterways
Containment: Scoop up spilled material and place in a properly labeled chemical waste container
Clean-up: Use damp paper towels or absorbent materials, thoroughly clean contaminated surfaces with water and detergent, ventilate area

Handling and Storage

Handling: Wear protective gloves, safety glasses, and appropriate laboratory clothing, minimize generation of dust, work in a fume hood if possible, avoid inhaling vapors or dusts, wash hands after handling
Storage: Store in tightly closed container, in a cool, dry, and well-ventilated place, separate from incompatible materials such as oxidizers or moisture, label all containers clearly, restrict access to trained personnel

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limits established specifically for this compound
Engineering Controls: Use fume hood or other appropriate containment to minimize exposure, ensure laboratory is equipped with eyewash stations and safety showers
Personal Protective Equipment: Wear chemical resistant gloves (such as nitrile or neoprene), safety goggles or face shield, laboratory coat, use respiratory protection if dust generation is possible or workplace limits are approached
Hygiene Measures: Wash hands before breaks and after work, avoid contact with skin and eyes, remove contaminated clothing promptly

Physical and Chemical Properties

Appearance: White to off-white crystalline powder
Odor: Mild, characteristic of organic salts
pH: Not available (aqueous solutions may be slightly acidic due to tetrafluoroborate hydrolysis)
Melting Point: 220°C (decomposition possible before melting)
Boiling Point: Decomposes
Solubility: Soluble in water, methanol, ethanol, slightly soluble in acetonitrile
Vapor Pressure: Not applicable
Density: Approximately 1.3 g/cm3
Partition Coefficient (log Pow): Not determined
Other Data: Hygroscopic, may form corrosive fumes in presence of moisture and acids

Stability and Reactivity

Reactivity: Reacts with water or acids to produce hydrogen fluoride and boron trifluoride gases
Chemical Stability: Stable under recommended storage conditions, sensitive to moisture, heat, and strong oxidizers
Hazardous Reactions: Contact with bases or strong acids may cause rapid decomposition, avoid elevated temperatures
Hazardous Decomposition Products: Hydrogen fluoride, boron trifluoride, nitrogen oxides, carbon oxides may be produced during combustion or degradation

Toxicological Information

Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Oral intake can cause gastrointestinal discomfort, possible central nervous system effects including dizziness, prolonged skin exposure leads to irritation, contact with eyes causes burning and redness
Chronic Effects: No long-term toxicity studies, repeated or prolonged exposure may increase risk of severe skin or respiratory irritation
Sensitization: Not reported for this specific compound, monitor for symptoms if used frequently
Carcinogenicity: Not classified by IARC, NTP, or OSHA
Additional Data: Limited toxicity data available, proper handling reduces adverse health effects

Ecological Information

Ecotoxicity: No specific aquatic toxicity data, related tetrafluoroborate salts can be harmful to aquatic organisms
Persistence and Degradability: Expected to be stable in environmental conditions, does not degrade rapidly, decomposes slowly via hydrolysis to fluoride and boron species
Bioaccumulative Potential: Low, expected for similar salts
Mobility in Soil: Compound likely leaches if released to environment, especially in moist soils, ionic nature suggests ready movement into groundwater
Other Adverse Effects: Releases of tetrafluoroborate or fluoride ions can impact local water quality, avoid spills or improper disposal

Disposal Considerations

Waste Treatment Methods: Collect all waste in compatible, clearly labeled containers for hazardous chemical disposal
Disposal of Product: Dispose of as hazardous chemical waste according to local, regional, and national regulations
Disposal of Packaging: Triple rinse contaminated containers if possible, puncture before landfill, match disposal method to local hazardous materials guidelines
Additional Notes: Do not allow to enter natural waterways or municipal sewers, consult a licensed chemical disposal contractor for larger quantities

Transport Information

UN Number: Consult latest regulations for specific UN assignment
UN Proper Shipping Name: Consult DOT, IATA, or IMDG lists
Transport Hazard Class: Generally not regulated for ground or air, may be subject to special rules in some regions
