Inhalation: Remove person to fresh air, keep at rest, medical attention required if persistent irritation, cough, or difficulty breathing develops
Skin Contact: Remove contaminated clothing and rinse skin immediately with plenty of water for 15 minutes, seek urgent medical care for blistering or burns
Eye Contact: Rinse cautiously with water for at least 15 minutes, lift eyelids occasionally, get immediate eye specialist attention
Ingestion: Do not induce vomiting, rinse mouth thoroughly with water, obtain urgent medical care, monitor for delayed gastrointestinal symptoms
Suitable Extinguishing Media: Use dry chemical powder or carbon dioxide, avoid water or foam as violent reaction with water occurs
Specific Hazards: Decomposes under fire conditions, produces hydrogen fluoride and other toxic gases, strong oxidizing agent
Protective Equipment: Wear full-body chemical-protective suit and self-contained breathing apparatus, approach fire from upwind direction
Firefighting Instructions: Fight fire from safe distance, avoid direct contact with vapors or decomposition products
Personal Precautions: Evacuate unnecessary personnel, ventilate area, use appropriate PPE including gloves, full face protection and chemical suit
Environmental Precautions: Prevent entry into drains, waterways, or soil
Cleanup Procedures: Carefully collect spillage using non-combustible, acid-resistant absorbents, transfer to labelled waste container, ventilate area after cleanup
Spill Size Response: Small spills can be neutralized with calcium carbonate or soda ash, large spills must be managed by trained hazardous material responders
Handling: Work inside certified chemical fume hood, avoid any moisture exposure, never add water to product, prevent inhalation of dust or fumes, use tools resistant to corrosion and oxidation
Storage: Keep in tightly closed containers made of compatible materials such as PTFE or nickel, store in cool, dry, well-ventilated chemical store away from water, acids, organic materials, and reducing agents, ensure containers are clearly labeled with oxidizer warnings
Special Precautions: Always check storage vessels for signs of corrosion or leaks, install emergency eyewash and safety shower stations nearby
Engineering Controls: Use local exhaust ventilation, implement enclosure systems for large-scale activities
Personal Protective Equipment: Wear heavy-duty chemical-resistant gloves (neoprene, butyl rubber), splash-proof goggles, full-face shield, chemical-resistant laboratory coat or suit, closed footwear, respiratory protection such as P3 filter mask or supplied-air respirator during risk of exposure
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing before leaving work area, decontaminate reusable gear regularly
Exposure Limits: Consult local occupational exposure standards for fluorides and inorganic bismuth compounds, maintain airborne concentrations below 0.1 mg/m3 for fluorides as a baseline

Respiratory Effects: Severe burning pain, pulmonary edema, chemical pneumonitis
Sensitization: No reliable data for skin or respiratory sensitization
Chronic Effects: Prolonged exposure may result in chronic respiratory issues, fluorosis, kidney or liver damage
Carcinogenicity: Not classified as carcinogen by NTP, IARC, OSHA
Mutagenicity/Teratogenicity: No reliable genotoxic or reproductive toxicity reports
Aquatic Toxicity: Extremely toxic to aquatic organisms, immediate and long-term negative impacts expected
Bioaccumulation Potential: Inorganic fluorides and bismuth compounds persist and accumulate in sediments, impact aquatic food chains
Mobility in Soil: Reacts violently on contact with water, results in local acidic contamination and mobilization of fluoride ions
PBT/vPvB Assessment: Not classified but persistent and bioaccumulative character is recognized for some breakdown products
Other Hazards: Toxic decomposition products harm soil microflora, plants, and invertebrates
Waste Treatment Methods: Collect waste in sealed, corrosion-resistant containers, label for hazardous inorganic fluoride waste, do not landfill untreated, neutralize with calcium carbonate in chemical waste facility under controlled conditions
Disposal of Contaminated Packaging: Triple-rinse empty containers with neutralizing solution, treat rinsate as hazardous waste, destroy containers by controlled incineration or send to specialized landfill
