Special Hazards: Spillage can cause slipperiness, runoff may contaminate ground or water supplies
Personal Precautions: Use gloves, eye/face protection, restrict contact with skin, avoid breathing vapors
Environmental Precautions: Dike spillage, prevent entry to drains, sewers or natural waterways, report to local authorities if contamination risk exists
Methods for Cleaning Up: Use absorbent inert material like sand, transfer residues to suitable chemical waste container, ventilate area, wash spill site thoroughly after material pickup
Handling: Handle in well-ventilated conditions, minimize dust formation, keep away from heat sources or open flames, avoid direct contact with skin or eyes, avoid ingesting or inhaling vapors
Storage: Keep containers tightly sealed, store in cool, dry, well-ventilated space with secondary containment, clearly label all storage containers, keep away from acids, bases, moisture and strong oxidizers
Incompatibilities: Moisture, strong acids, strong bases, oxidizing agents

Hazardous Decomposition: Yields hydrogen fluoride, boron trifluoride, carbon oxides under fire/thermal stress
Polymerization: Does not readily polymerize under normal laboratory conditions
Other Risks: Prolonged contact with light or air can slowly degrade purity
Acute Toxicity: Not fully assessed for all exposure routes in humans, animal models show low to moderate oral and dermal toxicity
Skin Contact: Prolonged or repeated exposure can produce dermatitis or irritation
Eye Contact: Transient redness, discomfort, tearing
Inhalation: Fine mist or aerosols may irritate upper respiratory tract; pre-existing conditions could worsen on exposure

Chronic Effects: No known evidence of mutagenicity, reproductive toxicity or carcinogenic risk based on available information
Sensitization: Cases of skin sensitization are rare but possible
Medical Symptoms: Redness, itching, coughing, mild headache, upset stomach after exposure
Aquatic Toxicity: Mild to moderate hazard, can impact fish and aquatic invertebrates at higher concentrations
Persistence and Degradability: Degrades slowly through hydrolysis and biodegradation, bioaccumulation potential considered low
Mobility: Highly soluble, may migrate in soil with water movement
Bioaccumulation: Limited evidence for significant bioconcentration in aquatic organisms
Other Effects: Runoff entering waterbodies could disturb local ecosystems; avoid uncontrolled discharges into environment
