Chemical Name: Bromine Pentafluoride
Concentration: 100%
CAS Number: 7789-30-2
Impurities or Stabilizers: None reported in reagent-grade material
Molecular Weight: 174.89 g/mol
Eye Contact: Rinse immediately with copious amounts of clean water for at least 15 minutes. Hold eyelids apart and avoid direct contact with contaminated water. Seek medical attention without delay even if symptoms appear mild.
Skin Contact: Remove contaminated clothing, rinse affected skin with high volumes of water for minimum 15 minutes. Use chemical shower if available. Immediate hospital consultation is critical; delayed effects possible.
Inhalation: Remove individual to fresh air at once. Begin artificial respiration if breathing fails; avoid mouth-to-mouth due to corrosive risk. Emergency medical services should be alerted right away. Administer oxygen if possible.
Ingestion: Do not induce vomiting. Rinse mouth thoroughly with water if possible yet ensure not to swallow. Never give anything by mouth to a person who is unconscious or convulsing. Immediate medical support essential.
Suitable Extinguishing Media: Water should not be used directly on chemical spill or burning product. Use dry sand, powdery extinguishing agents, or CO2 where compatible. Water can cause violent reaction and toxic gas release.
Specific Hazards: Decomposes under heat releasing toxic fumes including bromine and hydrogen fluoride. Reacts violently with combustible materials.
Protective Equipment: Firefighters need self-contained breathing apparatus and chemical-resistant protective clothing.
Advice for Firefighters: Move containers away from fire area if this can be done safely. Evacuate personnel to a safe distance. Water spray may be used for cooling unaffected tanks or containers. Avoid direct application to product.
Personal Precautions: Leave the immediate area. Use full-face positive pressure respiratory protection and chemically resistant clothing before approaching a spill.
Environmental Precautions: Prevent chemical from entering drains, soil, or water sources. Report releases to local regulatory bodies.
Cleanup Methods: Do not touch spilled material. Stop leaks if it can be done safely. Cover spill with dry sand or inert material; collect and transfer into secure, sealable chemical waste containers. Ensure area is ventilated and decontaminate site following approved procedures.
Emergency Measures: Restrict area with warning signs and control access.
Safe Handling: Only trained personnel in controlled environments should manage this product. Always use chemical fume hoods or ventilated enclosures. Do not allow contact with water, organic material, or combustibles.
Storage Conditions: Store in tightly sealed containers built from materials resistant to highly corrosive and oxidizing chemicals, such as nickel or Monel. Isolate from acids, organics, and all water sources. Place containers in cool, dry, well-ventilated secure areas. Maintain secondary containment and continuous monitoring for leaks.
Incompatible Materials: Almost all organics, water, metals except specified alloys, and combustible substances.
Occupational Exposure Limits: Bromine pentafluoride is not assigned a specific OSHA exposure limit, but air monitoring and best industrial hygiene practices must be followed. The ACGIH recommends rigorous area control and monitoring.
Engineering Controls: Chemical fume hoods, local exhaust ventilation, and properly maintained air purification equipment required.
Respiratory Protection: Full-face supplied-air respirators or SCBA required during any potential exposure.
Skin Protection: Chemically resistant suits, gloves (thick neoprene or butyl rubber, double-gloved), and boots.
Eye/Face Protection: Tight goggles and full-face shield; do not rely on a single protective device.
Hygiene Measures: Wash thoroughly after handling. Remove contaminated clothing promptly. Do not eat, drink, or smoke in work areas. Facility must offer eyewash stations and emergency showers.
Appearance: Colorless to yellow fuming liquid
Odor: Sharp, pungent odor resembling chlorine
Melting Point: -61.3°C
Boiling Point: 40.5°C
Density: 2.466 g/cm3 at 15°C
Solubility: Reacts violently with water
Vapor Pressure: 133 mmHg at 25°C
pH: Not applicable (reacts with water)
Flash Point: Not flammable, but an extreme oxidizer
Other Properties: Decomposes and fumes in air
Chemical Stability: Maintains stability in original sealed container. Sensitive to moisture and elevated temperature.
Reactivity: Highly reactive with organic or combustible material and strong reducing agents. Reacts violently with water to yield toxic and corrosive products.
Hazardous Reactions: Contact with most metals, water, acids, and organic substances will generate severe exothermic reaction and hazardous gases.
Decomposition Products: Emits bromine, fluorine, and hydrogen fluoride fumes when decomposed.
Incompatibility: Metals other than Monel or nickel alloys, glass, ceramics, organic materials, and water
Acute Toxicity: Lethal in low concentrations by inhalation. Animal studies report LC50 (rat, inhalation) at extremely low doses (below 50 ppm).
Skin Corrosion/Irritation: Causes rapid and deep chemical burns, severe pain, tissue destruction. Delayed necrosis reported.
Eye Damage: Direct contact results in immediate pain, severe necrosis, and potential for permanent vision loss.
Inhalation: Causes immediate and potentially fatal lung damage, bronchospasm, pulmonary edema, chemical pneumonitis.
Chronic Effects: Prolonged exposure may cause chronic lung damage, scarring.
Carcinogenicity: No data suggesting carcinogenic properties.
Sensitization: Not well documented.
Other Data: Severe systemic toxicity; risk for multi-organ involvement with sufficient dose.
Environmental Hazards: Highly toxic to all forms of life due to corrosive and oxidative effects. Hydrolysis in water produces acids lethal to aquatic and soil organisms.
Persistence and Degradability: Does not persist in environment; rapidly reacts forming bromine, fluoride, and strong mineral acids.
Bioaccumulation: Unlikely because of instability and rapid reaction.
Soil Mobility: High mobility due to immediate reaction and solubilization of products; persistent contamination possible.
Other Adverse Effects: Release into air forms dense fuming clouds, resulting in significant hazard downwind.
Waste Handling: Neutralization and destruction must take place under controlled laboratory conditions with proper neutralizing agents (typically calcium carbonate slurries) and qualified personnel.
Disposal Containers: Use sealed vessels built from corrosion-resistant materials such as Monel, securely closed, and correctly labelled.
Transport to Disposal: Engage only certified hazardous waste professionals licensed for oxidizers and corrosives.
Regulations: Comply with all local, state, and national hazardous waste disposal requirements. Do not mix with incompatible waste streams.
Spill Residues: Completely decontaminate all surfaces and equipment after clean-up.
