Other Identifiers: No significant non-listed ingredients expected beyond trace contaminants
Eye Contact: Rinse eyes carefully with water for several minutes; remove contact lenses if present and easy to do; seek medical attention if irritation persists
Skin Contact: Wash skin thoroughly with soap and plenty of water; remove contaminated clothing and shoes; medical care for persistent irritation
Inhalation: Move to fresh air; support breathing with oxygen if dizziness or difficulty starts; medical help if symptoms stick around
Ingestion: Rinse mouth with water; do not induce vomiting; seek medical advice for discomfort
Most Likely Symptoms: Mild irritation, coughing, redness to the eyes or skin
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Specific Hazards: Decomposition can produce toxic gases such as hydrogen bromide and carbon monoxide
Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Special Procedures: Cool containers with water spray; try to move containers from fire area if safe
Unusual Fire/Explosion Hazards: Dust buildup may present a risk of dust explosion in enclosed spaces
Personal Precautions: Wear gloves, eye protection, and dust mask; ventilate area
Spill Cleanup Methods: Sweep up without raising dust; collect material into suitable container for reuse or disposal; avoid dry sweeping if dust is present, use wet methods if possible
Environmental Precautions: Prevent entry into drains, watercourses, or soil; notify authorities if it reaches the environment
Emergency Procedures: Remove people from spill area and isolate; limit access until cleanup is done
Safe Handling: Avoid making dust; handle with care to avoid spills; wear protective gear
Hygiene Practices: Wash hands before eating, drinking, or smoking; change contaminated work clothes
Storage Conditions: Store in cool, dry, well-ventilated area away from direct sunlight, ignition sources or incompatible materials like strong oxidizers
Packaging: Keep in original containers or ones made of compatible plastic
Incompatible Materials: Strong oxidizing agents, acids
Engineering Controls: Use local exhaust or general room ventilation to keep airborne dust below limits
Occupational Exposure Limits: No established OSHA/ACGIH limit for DBDPE, but maintain total nuisance dust below 10 mg/m3 (inhalable), 3 mg/m3 (respirable)
Respiratory Protection: Use NIOSH-approved dust masks or respirators if dust exposure exceeds safe levels
Hand Protection: Wear chemical-resistant gloves
Eye Protection: Safety goggles or glasses with side shields
Skin Protection: Wear coveralls and closed footwear to avoid contact
Appearance: White or off-white granules or pellets
Odor: Mild or absent
Molecular Weight: 971.23 g/mol (active component)
Melting Point (DBDPE): Decomposition above 345°C
Solubility in Water: Insoluble
Density: About 1.9–2.3 g/cm3 (depends on carrier)
Vapor Pressure: Negligible
Flash Point: Not applicable (solid masterbatch)
Boiling Point: Decomposes before boiling
Stability: Stable in recommended storage and use conditions
Reactivity: No rapid reactions expected under normal process temperatures
Hazardous Decomposition Products: Thermal breakdown produces hydrogen bromide, oxides of carbon and other brominated byproducts
Incompatible Materials: Strong oxidizers and acids increase risk of hazardous reaction
Polymerization: Not expected to occur under normal handling
Acute Toxicity: Low acute toxicity by ingestion or skin contact, but dust can irritate airways and eyes
Skin Irritation: Prolonged or repeated skin contact may cause mild irritation
Eye Irritation: Dust may cause redness or discomfort
Chronic Health Effects: Some studies note possible liver effects and thyroid disruption in lab animals at high or repeated doses; evidence in humans remains limited
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Inhalation: Dust can aggravate asthma, bronchitis, and similar ailments
Ecotoxicity: Persistent in the environment; bioaccumulates in aquatic life; long-term adverse effects possible for aquatic ecosystems
Mobility in Soil: Results in environmental persistence, minimal degradation, tends to adsorb to sediment and organic matter
Persistence and Biodegradability: Resistant to natural breakdown; does not readily degrade
Bioaccumulation Potential: High potential, supported by monitoring and research on brominated flame retardants
Aquatic Toxicity: Fish and aquatic invertebrates can experience chronic toxicity from long-term exposure to dust or fines in water bodies
Waste Treatment Methods: Dispose of by landfill or regulated incineration; avoid uncontrolled release
Recycling: Collect uncontaminated spill material for possible recovery or recycling
Precautions: Follow local, regional, and national regulations for non-hazardous plastic waste containing brominated chemicals
Contaminated Packaging: Clean all used sacks or containers before recycling or disposal; treat packaging as chemical waste if significant residue remains
UN Number: Not regulated for transport as a hazardous material under typical shipment conditions
Transport Hazard Class: Not hazardous
