Inhalation: Move person to fresh air; if not breathing, give artificial respiration; get immediate medical advice if symptoms persist such as dizziness, headache, or coughing
Skin Contact: Remove contaminated clothing; wash skin with soap and plenty of water; if redness or irritation occurs, seek medical attention
Eye Contact: Rinse eyes cautiously with lukewarm water, lifting eyelids occasionally; continue for at least 15 minutes; remove contact lenses if present; get medical help for persistent irritation
Ingestion: Do not induce vomiting; rinse mouth; seek immediate medical attention; never give anything by mouth to an unconscious person
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam; water mist can cool containers
Unsuitable Media: High-pressure water jets may spread powder
Hazardous Combustion Products: Emits toxic antimony and bromine compounds, hydrogen bromide gas, carbon oxides
Protective Equipment for Firefighters: Full protective suit and self-contained breathing apparatus; stay upwind and avoid inhaling gases
Special Procedures: Prevent runoff from contaminating ground or surface water; cooled containers with water spray may reduce bursting risk
Personal Precautions: Evacuate area if high dust levels; wear NIOSH-approved dust respirator, goggles, chemical-resistant gloves, coveralls
Environmental Precautions: Prevent spillage from entering drains, soil, or natural waterways; contain dust with dampened rags or adsorbent material
Methods for Clean-Up: Sweep up, avoid raising dust; place residue in sealed, labelled containers for disposal; ventilate area after cleanup
Decontamination: Wash exposed skin, tools and equipment thoroughly with soap and water
Handling Practices: Use local exhaust ventilation at dust-generating points; avoid spills and airborne exposure; do not eat, drink, or smoke while handling; maintain good housekeeping
Storage Conditions: Keep in tightly sealed original containers; store in cool, dry, well-ventilated area away from food, feed, strong acids, alkalis, and oxidizing agents
Incompatible Materials: Avoid contact with strong bases, oxidizers, organic peroxides; segregate from other chemicals
Specific Storage Controls: Store away from direct sunlight and heat sources; label storage areas and restrict unauthorized entry
Occupational Exposure Limits: Antimony Trioxide 0.5 mg/m³ (NIOSH REL, 8hr TWA), TBBPA not established
Engineering Controls: Local exhaust ventilation, HEPA-filtered air systems, dust collection
Personal Protective Equipment: Safety goggles with side shields, nitrile gloves, chemical-resistant apron, dust mask (P100 or equivalent), powered air-purifying respirator for high concentrations
Industrial Hygiene Practices: Wash hands and face after handling; remove contaminated clothing; do not reuse soiled PPE without cleaning
Appearance: Fine white-to-off-white free-flowing powder or granules

Vapor Pressure: Negligible at room temperature
Solubility: Very low in water; partial in organic solvents
Density: 3.5–4.5 g/cm³ (composite blend)
Partition Coefficient (n-octanol/water): Not established
Explosive Properties: Not explosive
Oxidizing Properties: Not oxidizing
Chemical Stability: Chemically stable under proper storage; resists degradation up to 200°C
Possible Reactions: Reacts vigorously with strong oxidizing agents, acids, generating toxic fumes
Hazardous Decomposition: Antimony oxides, hydrogen bromide, carbon monoxide, carbon dioxide fumes if burned or overheated
Conditions to Avoid: High temperatures above 200°C, strong acids and bases, open flames, static discharge
Polymerization Risk: No hazardous polymerization under recommended conditions
Likely Exposure Routes: Inhalation, skin and eye contact, accidental ingestion during handling
Acute Effects: Irritation of respiratory tract, coughing, dryness, skin redness, eye discomfort, mild upset stomach if ingested
Chronic Effects: Long-term exposure may affect lungs, increase cancer risk (IARC Group 2B, possibly carcinogenic); dermatitis with repeated skin exposure
Animal Studies: Rats developed lung tumors after prolonged inhalation; high oral doses harmed liver and kidneys in rodents
Sensitization: No data suggesting sensitization
Mutagenicity: No strong evidence in animal testing
Ecotoxicity: Toxic to fish, aquatic invertebrates; LC50 (96h, fish): 2–3 mg/L (antimony trioxide); long-term harm to aquatic systems possible through bioaccumulation
Persistence / Degradability: Not readily biodegradable; highly stable in soil and water; persists in sediments
Bioaccumulative Potential: Antimony and brominated compounds can bioaccumulate in aquatic and terrestrial organisms
Mobility in Soil: Low to moderate migration through soil; partitioning to sediments likely
Other Adverse Effects: Releases to water may disrupt growth and reproduction in fish and amphibian populations
Waste Methods: Dispose via licensed hazardous waste facility; do not landfill in regular solid waste
Container Disposal: Rinse empty packaging thoroughly; treat as hazardous residue; puncture to prevent reuse
Environmental Caution: Prevent residue from entering drains, surface water, or municipal sewers; avoid incineration unless approved for halogenated wastes
