Impurities: Trace levels of debrominated forms and unreacted phosphine derivatives may be present; these add to toxicity profile
Inhalation: Move person to fresh air. If breathing problems develop, seek medical help. Support respiration if needed.
Skin Contact: Remove contaminated clothing, rinse with water for at least 15 minutes, clean thoroughly with gentle soap, get medical attention if irritation persists.
Eye Contact: Immediately rinse with water, lifting eyelids frequently, for at least 15 minutes, seek prompt medical advice.
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention without delay, provide medical team with product details.
Notes for Doctors: Treat symptomatically, monitor for respiratory distress and potential allergic response
Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder, alcohol-resistant foam; avoid water jets on larger quantities
Hazardous Combustion Products: Toxic and irritating fumes including phosphorus oxides, bromine compounds, carbon oxides
Protective Equipment: Full firefighting suit, self-contained breathing apparatus
Special Procedures: Cool containers nearby with spray water, contain run-off to avoid water pollution, keep personnel away from vapors or combustion products
Personal Precautions: Wear gloves, chemical splash goggles, lab coat, and respiratory protection if dust or vapor forms
Environmental Precautions: Prevent further leakage or spillage if safe, do not let product enter drains or surface water; notify authorities if large spill
Cleanup Methods: Absorb with inert material such as sand or vermiculite, collect spill and place in suitable closed container for disposal, wash area with plenty of water, ventilate affected space
Decontamination: Wash contaminated surfaces thoroughly—use detergent solution
Handling: Use in well-ventilated areas, avoid dust and vapor formation, no eating or drinking near product, keep containers closed
Storage Conditions: Keep container tightly sealed, store in cool, dry, well-ventilated place, protect from sunlight and moisture
Storage Class: As required by local regulations for hazardous chemicals
Incompatible Materials: Strong oxidizers, strong acids, certain metals and metal salts
Hygiene Measures: Wash hands after handling, remove contaminated clothing before entering eating or rest areas
Control Parameters: No established occupational exposure limits. Engineer to minimize potential exposures
Engineering Controls: Fume hood or local ventilation for open handling
Personal Protection: Nitrile gloves, chemical splash goggles, protective lab coat, approved respirator for dust or vapor exposure
Environmental Exposure: Procedures in place to contain and treat effluent; regular monitoring for groundwater or air contamination
Appearance: White or off-white solid, crystalline powder
Odor: Faint, but may irritate sensitive individuals
pH: Not applicable in solid state; neutral to mildly basic in solution
Melting Point/Range: Typically 90–120°C, dependent on purity
Boiling Point: Decomposes before boiling
Flash Point: Data not established; treat as combustible
Solubility: Soluble in water and polar organic solvents
Vapor Pressure: Negligible at ambient temperature
Density: Roughly 1.1–1.2 g/cm³
Partition Coefficient: Not measured, but expected to have moderate log Kow due to alkyl chain
Other Data: Stable under recommended storage, hygroscopic properties can complicate weighing or transfer
Chemical Stability: Stable under recommended use and storage, monitor for potential yellowing on long exposure to air
Conditions to Avoid: Heat, flame, sources of ignition, long-term UV exposure
Incompatible Materials: Strong oxidizers, acids, metal salts, halogenating agents
Hazardous Decomposition: Phosphorus oxides, bromine or hydrogen bromide, carbon oxides, volatile phosphine traces
Polymerization: Not expected under normal conditions
Acute Toxicity: Harmful if swallowed or inhaled, may irritate stomach and respiratory tract; estimated oral LD50 in the range of 500–2000 mg/kg in rats, exact data limited
Skin/Eye Irritation: Causes moderate to severe skin and eye irritation in animal models and based on structure-activity relationship
Sensitization: May cause allergic skin response in sensitive or repeatedly exposed individuals
Chronic Toxicity: No evidence for carcinogenicity but long-term data are sparse; chronic exposure can weaken liver or kidney function in sensitive individuals
Additional Data: Structurally related phosphonium compounds are not mutagenic, but bromide can increase incidence of neurological symptoms after high exposures
Ecotoxicity: Toxic to aquatic organisms, may cause long-term adverse effects in water systems
Persistence/Degradability: Not readily biodegradable, risk of long-term persistence especially in sediments
Bioaccumulation: Moderate potential due to dodecyl chain, data suggest log Kow in the 3–5 range
Mobility: Limited mobility in soil, slow leaching but may accumulate
Other Effects: Ecotoxicity enhanced at high doses; bromide ion toxic to certain freshwater and marine species even at low concentrations
Waste Handling: Do not dispose with general garbage or down drain
Regulatory Waste Codes: As specified for halogenated organic compounds
Disposal Methods: Incineration in chemical waste facility preferred, treat filtrates and washings as hazardous
Packaging Disposal: Contaminated packaging treated as product waste, follow all local hazardous waste rules
