Conditions to Avoid: Moisture, heat, incompatible chemicals
Hazardous Decomposition Products: Hydrogen fluoride, boron oxides, nitrogen oxides, carbon oxides; avoid inhaling any emitted gases
Incompatibility: Strong acids, oxidizing agents; may react vigorously or degrade
Acute Toxicity: Limited human data, extrapolated moderate toxicity based on quaternary ammonium and fluorinated salt class
Routes of Exposure: Inhalation, ingestion, skin, eyes
Symptoms: Irritation, headache, dizziness possible; large doses may cause nausea, vomiting
Skin Contact: Dryness, redness, dermatitis with repeated exposure
Eye Contact: Redness, pain
Chronic Effects: Data limited, but avoid chronic exposure due to unknowns with quaternary ammonium group and boron-fluoride
Carcinogenicity, Mutagenicity: Not listed by IARC, NTP, or OSHA
Other Risks: No known reproductive toxicity at typical lab concentrations; monitor new research publications for updates
Toxicity to Aquatic Life: No comprehensive studies, class-based risk for aquatic organisms due to fluorides and quaternary ammonium compounds
Persistence and Degradability: Persistent; doesn’t break down quickly in water or soil, potential for bioaccumulation of fluorinated components
Mobility in Soil: High solubility, possible migration to groundwater
Bioaccumulative Potential: Unknown for specific salt, but caution warranted due to non-degradability of tetrafluoroborate
