Name: Bromotrifluoroethylene
Chemical Formula: C2BrF3
Common Uses: Specialty gas for chemical synthesis, used in organic chemistry research and production
Physical Form: Gas under ordinary temperatures and pressures
Recognizable Odor: Sweet, possibly pungent aroma
Health Risks: This gas can irritate the respiratory tract, eyes, and skin upon contact. At higher concentrations, inhalation risk increases, especially for people with respiratory issues.
Flammability: Highly flammable. Ignition sources in the work area raise risk for fire or explosion.
Chemical Reactivity: Reacts with strong oxidizers, metals, and extreme heat; may release toxic or corrosive gases like hydrogen fluoride, bromides, and carbon oxides.
Chronic Exposure: Long-term repeated inhalation may cause lung function problems, so it pays to work in a well-ventilated spot.
Chemical Name: Bromotrifluoroethylene
CAS Number: 598-73-6
Purity: Usually above 98% for industrial work
Impurities: Minor traces of halogenated byproducts may be present in some grades used for research.
Inhalation: Get to fresh air quickly. If breathing trouble starts, use oxygen and call for medical help right away.
Skin Contact: Rinse the skin with plenty of water, take off contaminated clothing, and look for irritation. If the skin blisters or becomes painful, get medical attention.
Eye Contact: Use running water for at least fifteen minutes, holding eyelids open. Seek help if eyes keep burning or vision changes.
Ingestion: Not a typical risk since it’s a gas; in rare accidental cases, get prompt medical help. Do not induce vomiting.
Flammable Limits: Low ignition point; mixes with air rapidly.
Extinguishing Media: Use carbon dioxide, dry chemical powder, or foam—water may not be effective for a gas fire.
Protective Gear: Firefighters need self-contained breathing apparatus and turn-out gear, as burning material can release toxic byproducts.
Special Hazards: Confined spaces and pipelines may explode if exposed to heat or flame.
Evacuation: Move people away from the downwind area. Only let trained responders back to clean up.
Personal Protection: Respirators or full-face masks, chemical resistant gloves, and tight clothing should cover skin.
Enclosure: Prevent further release using shut-off valves or leak repair clamps where possible.
Ventilation: Vent the space to the outside. For outdoor releases, keep upwind.
Disposal: Contain and return to supplier if possible, or neutralize in a proper chemical scrubber or destruction unit.
Handling: Only people trained for gas cylinders and specialty gases should manage cylinders. Use tools rated for flammables. Avoid smoking and open flames in storage and usage areas.
Storage: Keep cylinders upright, secure, and cool. Mark the area as flammable gas storage. Far-away from oxidizers and incompatible chemicals. Get rid of old or unused gas promptly.
Leaks: Check for leaks using approved detection fluid. Never sniff for gas leaks by nose.
Ventilation: Good air movement in rooms where the gas is used. Local exhaust works best.
Personal Protection: Respirators when handling bulk amounts; splash goggles and gloves for any direct work especially if risk for liquid gas contact exists.
Monitoring: Use portable gas detectors and fixed monitors, especially if working with large volumes.
Clothing: Wearing chemical-resistant suits and boots keeps liquid splash off your body.
Occupational Limits: Exposure guidelines exist for similar halogenated gases, but nothing official for this specific substance. Keeping levels as low as possible in air cuts risk.
Appearance: Colorless gas
Odor: Sweet and sharp
Melting Point: Roughly -153°C
Boiling Point: Estimated near -58°C
Vapor Pressure: High at room temperature
Solubility: Low in water, higher in organic solvents
Density: Heavier than air
Stability: Unstable under strong heat, exposed metals, or light
Chemical Stability: Stable in cylinders under recommended conditions, but reacts in sunlight, heat, and with metals or oxidizers.
Reactivity: Contact with certain catalysts or open flame might kick off rapid decomposition or explosions.
Dangerous Byproducts: Decomposition lets out carbon monoxide, hydrogen fluoride, and bromine gas; all harmful to inhale.
Storage Containers: Only use tanks and fittings designed for corrosive and reactive gases.
Acute Effects: Short-term exposure hampers breathing, irritates eyes, skin, and upper airways. Prolonged breathing of higher concentrations risks more severe lung and nervous system problems.
Chronic Effects: Repeated low-level exposure slows reaction time or damages lungs. Animal data for similar compounds show damage to airway lining and kidneys.
Carcinogenicity: No conclusive data on cancer, but halogenated gases often warrant caution.
Target Organs: Lungs, central nervous system, skin.
Routes of Entry: Inhalation most common for workplace exposure.
Persistence: Highly stable in the environment. Likely remains for years if released into air.
Bioaccumulation: Little direct evidence for build-up in living things, but mobility in air raises global distribution prospects.
Aquatic Toxicity: Poor water solubility reduces direct harm to fish, but run-off or condensation near water could cause longer term issues.
Atmospheric Impact: As a volatile fluorinated compound, it could play a role in greenhouse gas accumulation or stratospheric chemistry, such as ozone depletion, based on analogues.
Preferred Methods: Return to supplier or specialized incineration that controls off-gas release. Simple venting may be illegal or hazardous.
Precautions: Never empty into public sewers or soil. Handle waste according to local rules on halogenated organics.
Packaging: Secure original containers during removal, label for hazardous material, and never reuse empty cylinders for other chemicals.
Shipping Class: Hazardous compressed gas
Packaging: Sturdy, pressure-rated gas cylinders. DOT and international guidelines demand proper hazard placards.
Transport Precautions: Secure against rolling, bumping, or heating during shipment. Only trained carriers should move gas cylinders.
Accident Response: In event of a spill during transportation, evacuate the area and follow emergency gas leak protocol.
US EPA/OSHA: Not directly listed, but covered by broad hazardous substance and workplace gas regulations.
International Regulations: Transport of this gas falls under international hazardous material codes (like UN recommendations).
Workplace Limits: Guidance based on structurally similar compounds; lab and factory policies tend to require monitoring and regular safety training.
Community Right to Know: Facilities storing or using large amounts likely need to report inventories to regulatory agencies and local fire departments.
