Decomposition Products: May release hazardous gases such as hydrogen fluoride, boron trifluoride, imidazole derivatives on heating or reaction with incompatible materials
Polymerization: No hazardous polymerization expected
Conditions to Avoid: Excess heat, contact with water in bulk, prolonged exposure to light or oxidants
Likely Exposure Routes: Inhalation of dust, skin or eye contact, ingestion
Acute Toxicity: Data limited; expected to cause irritation to eyes, skin, respiratory tract, no human data available on ingestion
Chronic Effects: Prolonged contact may cause dermatitis or eczema, risk to liver or kidney considered low at laboratory scale
Carcinogenicity: Not classified as carcinogen by IARC, NTP, OSHA
Sensitization: No information available, prudent to avoid repeated skin contact
Other Effects: In high doses, fluorinated compounds may irritate mucosa or cause fluoride toxicity
Aquatic Toxicity: Harmful to aquatic life, may cause long-term adverse effects in aquatic environments
Persistence and Degradability: Low biodegradability expected, stable ion in the environment
Bioaccumulative Potential: Potential for bioaccumulation based on structure, testing not conclusive
Mobility in Soil: Moderately mobile, soluble in water, risk of migration to groundwater if spilled
Other Harmful Effects: Tetrafluoroborate salts can persist, disrupt local water chemistry
