Fire-Fighting Measures

Suitable Extinguishing Media: Use CO2, dry chemical, alcohol-resistant foam, or water spray.
Specific Hazards: Emits toxic fumes under fire conditions, potential release of hydrogen fluoride and boron oxides when burned.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing.
Special Procedures: Cool containers with water spray to prevent bursting, avoid water runoff contamination.

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid contact with skin and eyes, use protective gloves and goggles.
Spill Cleanup: Absorb with inert material like sand or earth, transfer to proper chemical waste container, wash spill site after material pickup.
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid discharge into drains, water courses, or soil.

Handling and Storage

Handling: Work in well-ventilated areas, avoid inhalation of vapors, keep containers tightly closed when not in use, wear suitable protective equipment for eyes, skin, and respiratory tract.
Safe Practices: Use local exhaust ventilation if available, wash hands thoroughly after handling, avoid generating aerosols.
Storage: Store in a cool, dry, well-ventilated place, away from sources of ignition and incompatible materials such as strong oxidizers or acids, keep container tightly sealed, labeled, and out of reach of inexperienced persons.

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limit established for this specific compound, maintain exposure as low as reasonably achievable.
Engineering Controls: Use chemical fume hood, local exhaust, safety showers, and eyewash stations in work area.
Personal Protective Equipment: Chemical-resistant gloves (nitrile), safety goggles with side-shields or face shield, lab coat or apron.
Respiratory Protection: Use approval respiratory protection if airborne concentrations exceed recommended limits or during emergency response.
Hygiene Measures: Remove and wash contaminated clothing before reuse, do not eat or drink in chemical handling areas.

Toxicological Information

Routes of Exposure: Skin and eye contact, inhalation, ingestion.
Acute Toxicity: LD50 (Oral, rat) estimated 500–2000 mg/kg; limited data, assumed harmful.
Inhalation: May cause respiratory tract irritation.
Skin: Causes irritation, potential for dermatitis with prolonged exposure.
Eyes: Causes severe irritation, risk of damage with direct exposure.
Chronic Effects: No definitive data, repeated or prolonged exposure may lead to effects on liver and kidneys.
Carcinogenicity: No data supporting carcinogenic properties.
Mutagenicity / Teratogenicity: Not established

Ecological Information

Ecotoxicity: Expected to have moderate toxicity to aquatic organisms, due to presence of tetrafluoroborate anion, exact values not established.
Persistence and Degradability: Not readily biodegradable, resists microbial decomposition, potential for environmental accumulation.
Bioaccumulative Potential: Unlikely to bioaccumulate, lacks appreciable octanol-water partitioning but caution warranted.
Mobility in Soil: High mobility in aqueous environments, risk of leaching if released.
Other Adverse Effects: Avoid direct discharge to natural waters, harmful to aquatic ecosystems upon significant release.
