Product Name: Bromotrifluoromethane
Synonyms: Halon 1301, Trifluorobromomethane
Chemical Formula: CBrF3
Molecular Weight: 148.91 g/mol
CAS Number: 75-63-8
Recommended Use: Fire extinguishing agent, specialty chemical
Supplier Information: Manufacturer contact details and emergency telephone number must be included for specific locations and companies.
Emergency Phone Number: Refer to local safety protocol for emergency contacts.
Hazard Class: Gases under pressure, Compressed gas
GHS Label Elements: Cylinder pictogram, Warning signal word
Hazard Statements: Contains gas under pressure; may explode if heated. Can cause suffocation by displacing oxygen. High concentrations might cause cardiac arrhythmia. Rapid release may result in frostbite due to cold gas.
Precautionary Statements: Store away from direct sunlight and hot surfaces. Ensure proper ventilation. Avoid breathing gas, use only with adequate ventilation.
Routes of Entry: Inhalation
Acute Effects: Dizziness, drowsiness, cardiac sensitization to catecholamines, frostbite on skin contact with rapidly-released liquid
Chronic Effects: Repeated exposure can affect heart rhythm and nervous system, leading to long-term health problems.
Environmental Impact: Hazardous for ozone layer, classified as an ozone-depleting substance.
Chemical Name: Bromotrifluoromethane
Concentration: 100%
CAS Number: 75-63-8
Impurities: None typically expected in high-purity product. Specify source for details.
Inhalation: Remove person to fresh air. Use supplemental oxygen and artificial respiration if breathing has stopped. Seek medical attention immediately for any breathing difficulty.
Skin Contact: Remove contaminated clothing. For frostbite, immediately immerse affected area in warm water (do not exceed 40°C). Do not rub. Seek medical attention for burns.
Eye Contact: Flush eyes with lukewarm water. Hold eyelids apart and rinse continuously for 15 minutes. Get medical attention if irritation persists or vision changes.
Ingestion: Not a typical route of exposure, but if swallowed or inhaled in large amounts, seek medical help rapidly.
Most Important Symptoms: Dizziness, irregular heartbeat, shortness of breath, frostbite
Notes to Physician: Avoid epinephrine or similar drugs in case of irregular heartbeat triggered by exposure.
Suitable Extinguishing Media: Product is used as a fire extinguishing agent; use appropriate media for surrounding fire.
Fire Hazards: Cylinders may explode in heat or fire conditions due to pressure rise.
Decomposition Products: Hydrogen bromide, hydrogen fluoride, carbonyl halides, which are corrosive and toxic.
Protective Equipment: Firefighters should use a full-face self-contained breathing apparatus and full protective gear.
Special Procedures: Cool fire-exposed containers with water spray. Remove containers from fire area if possible.
Explosion Risk: Risk of cylinder explosion if pressure is not controlled.
Personal Precautions: Ventilate area. Wear appropriate personal protective equipment including respiratory protection.
Environmental Precautions: Prevent release to environment, especially drains and waterways. This product contributes to ozone depletion.
Containment Methods: Stop leak if safe to do so. Use natural ventilation, or forced ventilation in confined spaces.
Cleaning Methods: Allow gas to dissipate in a safe and well-ventilated area. Evacuate personnel until gas has dispersed.
Spill Management: Evacuate non-essential personnel. Monitor oxygen levels, as the gas can displace air, causing an asphyxiation hazard.
Handling: Use only in well-ventilated areas. Avoid inhalation and skin contact. Never use or handle near open flames, hot surfaces, or sources of ignition. Do not manually open pressurized containers.
Storage Conditions: Store cylinders in cool, dry, well-ventilated areas away from direct sunlight, heat, and sources of ignition. Secure cylinders to prevent falling or rolling.
Incompatible Materials: Avoid contact with strong bases, alkali metals, and reactive metals such as magnesium. Chemical reacts with very hot surfaces to release toxic breakdown products.
Special Requirements: Label and segregate as ozone-depleting chemical according to local regulations.
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below exposure limits.
Occupational Exposure Limits: No OSHA established permissible exposure limit; ACGIH TLV: 1000 ppm (5650 mg/m3), NIOSH REL: 1000 ppm

Other Health Effects: Exposure may exacerbate pre-existing heart conditions
Ecotoxicity: Hazardous to the ozone layer; classified as an ozone-depleting substance.
Aquatic Toxicity: No evidence of direct aquatic toxicity at environmentally relevant concentrations.
Soil Mobility: High volatility, unlikely to bioconcentrate in soil or sediment
Partition Coefficient: Not biological, rapidly vaporizes
Bioaccumulation Potential: Low due to volatility
Degradation: Long atmospheric lifetime, 65 years (approximate), which increases its impact on atmospheric chemistry
Waste Treatment: Do not discharge to atmosphere without proper abatement. Collect residues and dispose according to local and national regulations.
