Chemical Identity: Polybrominated diphenyl ether mixture
Main Component: Pentabromodiphenyl ether, 95–98%
Other Brominated Diphenyl Ethers: 1–4% by weight, varies by source
Impurities: Trace octa- and nona-bromodiphenyl ethers, possible under 1%
Additives: May contain stabilizers or anti-caking agents under 0.5%
Inhalation: Move to fresh air, keep warm and at rest, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for at least 15 minutes, seek medical advice for persistent irritation
Eye Contact: Flush eyes with water for 15 minutes, avoid rubbing, get prompt medical evaluation
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical assessment, show physician the MSDS
Symptoms of Exposure: Irritation of skin, redness in eyes, respiratory discomfort, abdominal pain, nausea on ingestion
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide, avoid direct water jets
Hazardous Combustion Products: Hydrogen bromide, brominated aromatic compounds, carbon monoxide, carbon dioxide, toxic smoke
Protective Equipment: Wear self-contained breathing apparatus and full protective suit
Fire and Explosion Hazards: Combustible at elevated temperatures, releases dense and noxious fumes
Firefighting Instructions: Control run-off to prevent environmental impact, move containers from fire zone if safe
Personal Precautions: Evacuate unnecessary personnel, wear gloves, eye protection, and particulate respirator
Spill Cleanup: Avoid creating dust, sweep or vacuum using explosion-proof equipment, transfer material to labeled containers
Environmental Precautions: Prevent entry to sewers, surface waters, and soil
Decontamination: Wash spill site thoroughly after pickup is complete, ventilate area
Handling: Avoid dust formation, use only in ventilated areas, avoid contact with skin and eyes, wash hands thoroughly after handling
Storage: Store in tightly closed containers, away from sources of heat, ignition, and incompatible chemicals, in a cool, dry, well-ventilated space
Incompatible Materials: Strong oxidizers, reducing agents, acids
Storage Class: Toxic substance, keep away from food and drink, label clearly
Engineering Controls: Use local exhaust and process enclosure, maintain airborne concentration below occupational limits
Personal Protection: Wear protective gloves, chemical-resistant clothing, safety goggles, and particle respirators
Hygiene Measures: Do not eat, drink, or smoke during use, wash exposed areas after work
Occupational Exposure Limits: ACGIH and OSHA set limits for nuisance dust (10 mg/m³, 8h TWA for inhalable particles), though no established specific value for pentabromodiphenyl ether exists
Appearance: Off-white to light tan powder or flakes
Odor: Odorless or faint aromatic smell
Melting Point: 190°C – 206°C
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible at room temperature
Solubility: Virtually insoluble in water, slightly soluble in organic solvents (acetone, toluene)
pH: Not applicable (insoluble)
Flash Point: Not easily ignitable
Density: About 3.2 g/cm³
Partition Coefficient (log Kow): 6.5 – 7.6, means strong tendency to bioaccumulate
Decomposition Temperature: Above 240°C, emits toxic fumes
Chemical Stability: Stable under normal storage and handling conditions
Conditions to Avoid: Excessive heat, strong UV light, open flame
Incompatible Materials: Strong acids, bases, oxidizing agents
Hazardous Decomposition Products: Brominated dioxins, hydrogen bromide, other brominated compounds on thermal breakdown
Polymerization: Does not occur under normal conditions
Acute Effects: Mild to moderate skin and eye irritation, may cause respiratory tract irritation
Chronic Effects: May impact thyroid and liver, linked with reproductive and developmental risks in laboratory animal studies
Carcinogenicity: Classified as possible carcinogen by some agencies, not proven in humans
Routes of Exposure: Inhalation of dust, skin contact, accidental ingestion
Symptoms: Nausea, headache, dermatitis, breathing difficulties in high dust scenarios
LD50 (oral, rat): Above 5,000 mg/kg, shows low acute toxicity but repeated exposure risks accumulate
Other Information: No validated data on human cancer risk but studies suggest potential endocrine disruption
Ecotoxicity: Highly toxic to aquatic organisms, bioaccumulates in food chains
Persistence: Persists in soil, sediment, and water for long periods
Bioaccumulation Potential: Significant, due to high log Kow, accumulates in fatty tissues
Mobility: Attaches to particulates in soil, low mobility in groundwater
Aquatic Impact: Chronic toxicity observed in invertebrates and fish, biomagnification documented in real-world monitoring
Soil Impact: Resistant to microbial degradation, can remain for decades
Waste Treatment Methods: Incinerate at high temperature in authorized facility equipped with emission controls
Contaminated Packaging: Dispose of containers as hazardous waste, do not reuse
Disposal Restrictions: Do not disposal in landfill or sewer, prohibit burning in open areas
Recycling: Not recommended, contamination remains high
Special Handling: Label waste containers with full identity and hazard warning, track movement as per local hazardous waste regulations
UN Number: Not regulated for transport under UN model regulations in most jurisdictions, but check local restrictions
Proper Shipping Name: Pentabromodiphenyl ether, technical grade
Transport Hazard Class: No class assigned, treated as environmentally hazardous substance in some countries
Packing Group: None specified unless local guidelines apply
Environmental Hazards: Marine pollutant marking needed if subject to IMDG Code
Special Transport Precautions: Protect from rain and direct sunlight, minimize container movement, ensure outer packaging is secure and leakproof, documentation should accurately declare hazard statements
Global Inventories: Listed, restricted, or banned in many national or regional chemical inventories (REACH, TSCA, Canada DSL/NDSL, Japan ENCS, Australia AICS)
Restrictions: Production and use severely limited or phased out in Europe, US, and several Asian countries due to persistent organic pollutant (POP) classification
