Protective Equipment and Precautions: Firefighters should use self-contained breathing apparatus and full protective clothing
Additional Information: Cool exposed containers with water to prevent rupture; contain runoff to avoid environmental contamination
Personal Precautions: Use dust respirator, gloves, and protective clothing; ventilate area
Environmental Precautions: Prevent product from entering drains, soil, or watercourses
Containment: Collect spilled powder using non-sparking tools and place in tightly sealed containers for proper disposal
Cleanup Methods: Vacuum or sweep up without generating dust, avoid dry sweeping, clean area thoroughly
Waste Disposal: Dispose of collected material in accordance with local, regional, and national regulations, avoid release to the environment
Safe Handling: Handle with proper protective equipment to minimize dust exposure, avoid eating, drinking, or smoking in use areas
Precautions: Keep containers closed when not in use, avoid contact with incompatible materials, use in well-ventilated areas
Storage Requirements: Store in a dry, cool, well-ventilated location, away from direct sunlight and sources of ignition
Incompatible Materials: Strong oxidizing agents, acids
Packaging Materials: Store in original packaging or compatible containers designed for chemical storage
Occupational Exposure Limits: No established national limits for DBDPE, use general nuisance dust limits (respirable fraction: 3 mg/m³, inhalable fraction: 10 mg/m³)
Engineering Controls: Use local exhaust ventilation or process enclosure to reduce airborne dust
Personal Protective Equipment: NIOSH-approved dust respirator, chemical-resistant gloves, safety goggles, long-sleeved protective clothing
Hygiene Measures: Wash hands and face after handling, remove and wash contaminated clothing before reuse
Environmental Controls: Use pollution control measures as required to prevent workplace and environmental contamination
Appearance: White to off-white powder or granules

pH: Not applicable (insoluble in water)
Boiling Point: Decomposes before boiling
Melting Point: 350–370°C (decomposition may start in this range)
Flash Point: Not readily flammable
Solubility: Virtually insoluble in water; slightly soluble in organic solvents
Vapor Pressure: Essentially zero at ambient temperature
Density: About 3.3–3.5 g/cm³
Partition Coefficient (log Kow): Estimated at around 11, indicating strong bioaccumulation potential
Other Properties: Negligible volatility, stable under recommended storage and handling conditions
Chemical Stability: Stable under normal conditions of use and storage
Reactivity: Nonreactive under standard environmental and use situations
Hazardous Decomposition Products: Heating or burning creates hydrogen bromide, carbon monoxide, carbon dioxide
Conditions to Avoid: Excessive heat, open flames, prolonged exposure to sunlight
Incompatible Materials: Strong oxidizers may cause hazardous reactions
Polymerization: Not expected to occur
Acute Toxicity: Low oral and inhalation toxicity in animal studies; LD50 (oral, rat) >5000 mg/kg
Chronic Toxicity: No clear evidence for chronic human toxicity but long-term data lacking
Skin Corrosion/Irritation: Slight skin irritant in laboratory tests
Eye Damage/Irritation: Mild, reversible irritation possible
Sensitization: No evidence of skin sensitization reported
Mutagenicity and Carcinogenicity: No data indicate carcinogenic or mutagenic risk at currently understood exposure levels
Other Potential Effects: Dust inhalation may cause respiratory tract irritation
Ecotoxicity: Very toxic to aquatic organisms, long-term effects due to extreme persistence and bioaccumulation
Persistence and Degradability: Highly persistent in soil, sediment, and water; not readily biodegradable
Bioaccumulative Potential: High potential for bioaccumulation in aquatic and terrestrial food webs
Mobility in Soil: Likely to partition to sediments and particulate matter; low mobility in groundwater
Other Adverse Effects: Concern in the scientific community over transfer and accumulation in ecosystems; long-term monitoring recommended
Disposal Methods: Use a licensed hazardous waste contractor; incinerate in permitted facility with proper technology to handle brominated compounds; avoid landfill disposal if possible
Packaging Disposal: Dispose of contaminated packaging as hazardous waste in accordance with local, regional, and national regulations
