Inhalation: Move to fresh air. Keep comfortable for breathing. Seek medical attention for persistent symptoms such as coughing, chest discomfort, or dizziness.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Do not use solvents. Get medical help for irritation or burns.
Eye Contact: Rinse cautiously with clean water for at least 15 minutes and remove contact lenses. Continue rinsing and get medical attention for redness, pain, or blurred vision.
Ingestion: Rinse mouth. Drink water only if conscious. Do not induce vomiting. Call poison control or seek urgent medical help.
Notes for Doctors: Treat symptomatically based on patient’s condition and symptoms. Watch for late-onset respiratory distress if fumes were inhaled.
Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide, or water spray
Unsuitable Media: Direct water jet on burning mass can spread molten product
Unusual Hazards: Burning releases carbon monoxide, carbon dioxide, hydrogen bromide, and antimony compounds
Firefighter Protection: Wear self-contained breathing apparatus and full firefighting gear. Avoid inhaling smoke or fumes.
Fire Residues: Collect extinguishing runoff separately to avoid environmental contamination
Personal Precautions: Use gloves, goggles, dust mask for loose pellets or powder. Remove ignition sources.
Environmental Precautions: Prevent entry into drains, rivers, or soil. Avoid dust and fume dispersion.
Cleanup Methods: Sweep up mechanically, avoid raising dust. Place in secure, labeled containers for disposal. Ventilate contaminated area.
Advice for Emergency Responders: Use respiratory protection for spill cleanup in confined or poorly ventilated spaces.
Handling: Avoid breathing dust, fumes, or vapor from hot processing. Use local exhaust or general ventilation. Do not eat, drink, or smoke during handling. Wash hands after contact.
Storage: Store in a dry, cool, well-ventilated area away from strong acids, bases, oxidizers. Keep in tightly sealed, original packaging or containers.
Storage Temperature Range: 5–30°C. Protect from direct sunlight, heat sources, and freezing.
Incompatible Materials: Strong acids, bases, methyl ethyl ketone, and powerful oxidizers
Other Considerations: Keep containers upright and prevent damage to packaging or labels.
Occupational Exposure Limits: Antimony Trioxide—0.05 mg/m³ TWA (ACGIH); Decabromodiphenyl Ethane—not established, use general dust limits
Engineering Controls: Local exhaust ventilation at the source; general room ventilation
Personal Protective Equipment: Protective gloves (nitrile, latex), safety goggles, half-mask respirator (P2 if dust, ABEK if fumes), chemical-resistant apron for high volume handling
Hygiene Measures: Do not touch face or eyes when using. Wash thoroughly at the end of shifts or before eating. Remove contaminated clothing and wash before reuse.
Appearance: Opaque or slightly translucent granules, various colors possible
Odor: Slight characteristic odor, more intense on heating
pH: Not applicable (solid, non-soluble in water)
Melting/Softening Point: 150–220°C range depending on grade
Boiling Point: Not applicable
Flash Point: Exceeds 350°C (closed cup, not easily ignited)
Decomposition Temperature: Above 300°C
Solubility: Insoluble in water, partially soluble in organic solvents
Flammability: Self-extinguishing. Will melt then burn if sustained flame. UL94 V-0 depending on content.
Vapor Pressure: Not relevant (solid at normal temperatures)
Density: 1.10–1.30 g/cm³
Viscosity: Not applicable (solid)
Chemical Stability: Stable under normal handling and storage conditions
Hazardous Reactions: No dangerous reaction under standard use; reacts with strong oxidizers
Conditions to Avoid: Open flame, direct sunlight, temperature above 50°C for extended periods
Hazardous Decomposition Products: Under fire, may produce carbon monoxide, hydrogen bromide, antimony oxides, other irritating or toxic gases
Incompatible Materials: Avoid contact with strong acids, bases, oxidizing materials, and certain amines
Acute Toxicity: Ingestion can cause nausea, vomiting, abdominal pain. Fumes may irritate respiratory tract.
Skin Contact: Prolonged contact may cause irritation, reddening, minor swelling.
Eye Contact: Dust or fragments may irritate, cause watering and redness. Fume exposure may worsen effects.
Chronic Effects: Long-term inhalation of dusts containing antimony compounds may affect lungs or other organs.
Mutagenicity and Carcinogenicity: Antimony trioxide classified by IARC as Group 2B (possibly carcinogenic to humans). Brominated flame retardants suspected to pose reproductive and developmental toxicity risks with extended exposure.
Aquatic Toxicity: Low solubility of polymer matrix but leaching of antimony and brominated compounds possible in aquatic environments; harmful to aquatic life with long lasting effects.
Soil Mobility: Generally immobile as polymer, but additives may migrate over time; risk increases if improperly disposed or incinerated.
Persistence and Degradability: Highly persistent in soil and water; slow degradation takes years.
Bioaccumulation: Additives potentially bioaccumulative in aquatic species.
Other Harmful Effects: Avoid uncontrolled release into environment; do not incinerate unless using exhaust gas filtering systems.
Disposal Methods: Send solid waste to licensed hazardous material incinerator or approved landfill. Recycling possible for clean, uncontaminated scrap through specialist services.
Incineration: Only in facilities with scrubbing/filtering for bromine- and antimony-containing fumes.
Container Disposal: Empty containers must be scraped clean and sent for specialized disposal or recycling if available. Never reuse uncleaned containers.
Do Not: Discharge to sewers, open water, or regular municipal trash.
UN Number: Not regulated under standard transport criteria for dangerous goods
Transport Hazard Class: Not classified
Packing Group: Not applicable
Proper Shipping Name: Not regulated
Special Precautions: Avoid heavy impact and high temperature during shipping. Prevent packaging rupture. Label as “Plastic Material – Keep Dry”
Transport in Bulk: Use sealed containers to avoid spillage or contamination on route.
TSCA (USA): All components listed or exempt
REACH (EU): All substances registered, needs verification for lead component compliance
OSHA Status: Hazardous due to antimony and decabromodiphenyl ethane
RoHS Status: Restricted for electrical/electronic products due to brominated and antimony compounds
SARA 313: Antimony compounds require reporting
Other Local Requirements: Regional disposal and import/export controls for flame retardants and heavy metal contents apply in many countries
