Product Name: Bromochlorodifluoromethane
Chemical Formula: CBrClF2
Synonyms: Halon 1211
Appearance: Colorless, odorless gas under standard conditions
Common Uses: Fire extinguishers, especially found in aviation and industrial settings
Main Hazards: Asphyxiation risk in confined spaces, cardiac sensitization, central nervous system depression
Eye Exposure: May irritate or cause discomfort due to cold gas expansion
Skin Contact: Frostbite on direct contact with liquid
Inhalation: Headache, dizziness, irregular heartbeat, risk of cardiac arrest at high concentrations
Label Warnings: Pressurized, asphyxiant, hazardous decomposition gases
Chemical: Bromochlorodifluoromethane
CAS Number: 353-59-3
Concentration: Approximately 100% in pure form
Impurities: Generally minor; may include low-level water or container-derived trace substances
Inhalation: Move to open air, monitor breathing, provide oxygen or CPR if needed
Skin Contact: Remove contaminated clothing, flush area with lukewarm water, avoid rubbing the area, apply clean dressing for frostbite signs
Eye Exposure: Rinse thoroughly with water for several minutes, seek medical attention if irritation persists
Ingestion: Unlikely due to gaseous state, but treat symptoms and consult a physician
Note for Responders: Watch for symptoms similar to cardiac event, do not leave affected person alone
Suitable Extinguishing Media: Gas itself is an extinguishing agent
Special Equipment: Self-contained breathing apparatus for firefighters, protective clothing
Hazardous Combustion Products: Hydrogen halides, phosgene, toxic fumes on thermal decomposition
Fire Hazards: Releases toxic fumes when heated, can displace oxygen in small spaces
Explosion Data: Does not burn or explode but creates hazardous environments during fire conditions
Personal Protection: Wear respiratory protection for leaks in enclosed areas, ventilate space
Environmental Precautions: Prevent release to atmosphere, since halons have strong ozone-depleting potential
Clean-up Procedure: Isolate leak, air out space, avoid contact with gas or liquid phase, evacuate non-essential personnel
Storage Requirements: Store cylinders upright, away from sources of heat, direct sunlight, ignition
Handling Precautions: Use only in well-ventilated areas, avoid rough handling that could cause cylinder rupture
Temperature Conditions: Avoid temperatures above 54°C to prevent pressure build-up
Special Advice: Do not attempt to modify or repair pressurized containers
Labeling: Follow local fire safety and chemical labeling rules
Engineering Controls: Local exhaust ventilation in work areas
Respiratory Protection: Wear appropriate respirators in confined or unventilated areas
Skin Protection: Gloves for possible contact with liquid or gas
Eye Protection: Chemical safety goggles
Occupational Exposure Limits: No safe exposure threshold – aim for minimal exposure due to cardiac risk
State: Gas at room temperature, liquefies under pressure
Odor: None
Color: Colorless
Boiling Point: -4°C
Melting Point: -159°C
Solubility in Water: Negligible
Vapor Pressure: High at room temperature
Relative Density: Heavier than air
Flammability: Nonflammable
Chemical Stability: Stable under recommended storage conditions
Reactivity With: Alkali metals or finely divided metals may generate halide salts and possible fires
Hazardous Reactions: Decomposes at high temperatures to toxic substances (hydrogen halides, phosgene)
Incompatible Materials: Strong bases, aluminum, magnesium in powdered form
Acute Effects: High concentrations rapidly depress central nervous system, induce irregular heartbeat leading to possible cardiac arrest
Chronic Effects: No clear evidence for long-term carcinogenicity, but repeated exposure under sub-acute levels not recommended
Symptoms of Overexposure: Nausea, dizziness, shortness of breath, confusion, unconsciousness
Routes of Entry: Inhalation is primary risk, direct skin contact poses frostbite hazards
Ozone Depletion: High ozone-depleting potential compared to most industrial gases
Aquatic Toxicity: Not significant compared to atmospheric concerns
Bioaccumulation: Not expected
Persistence: Can remain in atmosphere for years, contributing to ozone layer damage
Wider Impact: Atmosphere contains lower concentrations now due to phase-out, but legacy releases still cause concern in environmental health circles
Recommended Disposal: Reclaim for reuse if possible, work with licensed hazardous waste contractors
Prohibited Practices: Do not vent directly to atmosphere under any circumstances
Environmental Law: Subject to strict disposal controls due to ozone impact
Waste Code: Follows local, regional, and national hazardous waste codes
Recycling: Available in specialized facilities, not through general recycling or waste streams
Shipping Class: Compressed gas, hazardous
Proper Shipping Name: Bromochlorodifluoromethane, Compressed Gas
Packing Group: As defined by transport guidelines
Transport Precautions: Ensure cylinders are secure, valves protected, never transport with food or incompatible hazardous materials
Emergency Procedures: Train drivers in leak response and evacuation protocols; notify authorities immediately for spills or releases in transit
Ozone Control Act: Subject to restrictions or phase-out under many international treaties, such as the Montreal Protocol
Chemical Inventory: Listed in many national registries
Worker Safety: Must comply with regional workplace health and safety rules
Labeling and Marking: Follows global harmonized system for hazardous chemicals
Legal Restrictions: Use mostly limited to critical or exempted fire suppression applications due to environmental law
