Inhalation: Move person to fresh air right away, keep comfortable for breathing, get medical attention if symptoms develop (such as coughing or shortness of breath)
Skin Contact: Immediately remove contaminated clothing, wash affected skin with mild soap and plenty of lukewarm water, seek medical attention if irritation or rash occurs
Eye Contact: Rinse eye cautiously with water for at least 15 minutes lifting upper and lower eyelids, remove contact lenses if present and easy, seek medical attention for persistent irritation or vision changes
Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, seek medical advice as soon as possible
Symptoms: May cause redness, irritation, or gastrointestinal discomfort depending on route of exposure
Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, or foam; water spray for surrounding fire
Unsuitable Media: Avoid high-pressure water jets directly on solid product; risk of chemical runoff
Hazardous Combustion Products: Phosphine oxides, carbon monoxide, carbon dioxide, hydrogen bromide gas, aromatic brominated compounds
Specific Hazards: May give off toxic fumes under fire conditions, risk of inhalation exposure to decomposition products
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear during response
Personal Precautions: Equip with gloves, goggles, dust mask or suitable respirator, remove ignition sources, ensure adequate ventilation
Environmental Precautions: Prevent release to drains, surface water, or soil; avoid contamination of sewers
Cleanup Methods: Sweep up material carefully, collect in suitable container for disposal, avoid creating dust, ventilate area, clean spill sections with water and detergent
Decontamination: Clean tools and contact surfaces thoroughly after containment, wash affected skin areas, segregate waste for appropriate disposal
Handling: Avoid direct contact with skin, eyes or clothing, use in well-ventilated areas or chemical fume hood, do not eat, drink or smoke while handling
Storage: Store tightly closed in a cool, dry, well-ventilated place away from heat sources, direct sunlight, acids, and oxidizing agents, keep container upright and clearly labeled, restrict access to trained personnel
Incompatible Materials: Strong oxidizers, strong acids, halogenated compounds
Storage Life: Consult supplier guidance for long-term stability, typically stable for one year under recommended storage conditions
Engineering Controls: Use local exhaust ventilation, laboratory fume hood, or equivalent engineering controls to minimize exposure
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene recommended), safety goggles, lab coat, closed-toe shoes, respiratory protection if dust risk exists
Hygiene Measures: Wash hands after handling, immediately remove contaminated clothing, maintain clean working area
Exposure Limits: No established OSHA, ACGIH, NIOSH, or international limits; handle as hazardous chemical regardless
Appearance: White to off-white crystalline solid
Odor: Odorless or faint aromatic odor
Boiling Point: Not applicable (decomposes before boiling)
Melting Point: 220-236°C (batch-dependent)
Solubility: Soluble in polar organic solvents (e.g., acetonitrile, methanol); sparingly soluble in water
Density: About 1.36 g/cm³
Vapor Pressure: Negligible at room temperature
pH (aqueous solution): Not available
Flash Point: Not relevant (solid nonflammable under ambient conditions)
Partition Coefficient (log Kow): Not established
Chemical Stability: Stable under recommended storage conditions, sensitive to moisture and strong light
Reactivity: Can react with strong oxidizers, strong acids, and halogenating agents
Hazardous Decomposition Products: Hydrobromic acid, triphenylphosphine oxide, aromatic hydrocarbons upon thermal decomposition
Conditions to Avoid: Excessive heat, direct sunlight, ignition sources, humid or damp environments
Polymerization: Will not polymerize under normal conditions
Acute Toxicity: Moderately toxic by ingestion; oral LD50 (rat) data not specified
Chronic Effects: Data on chronic effects limited, repeated exposure may cause dermatitis or sensitization
Skin Corrosion/Irritation: Causes irritation on contact; avoid repeated skin exposure
Eye Damage/Irritation: Risk of redness and serious irritation
Respiratory Effects: Inhalation of dust may provoke coughing or shortness of breath
Carcinogenicity: No evidence from regulatory agencies indicating carcinogenic risk; insufficient long-term studies
Reproductive and Developmental Effects: No specific studies or data available; handle with care in all reproductive safety contexts
Mutagenicity: Not classified as mutagenic due to lack of data
Ecotoxicity: Likely harmful to aquatic life if released into water systems; acute and long-term ecological consequences not fully characterized
Mobility in Soil: Expected to have low mobility due to low water solubility
Persistence and Degradability: Not readily biodegradable; can persist in environment
Bioaccumulation Potential: Data not available, possible moderate bioaccumulation based on structure
Other Adverse Effects: Avoid environmental release, minimize handling and dispose of waste properly
Waste Treatment Methods: Gather waste in sealed, labeled containers suitable for hazardous waste disposal
Disposal Recommendation: Dispose of at an approved waste facility in compliance with local, state, and national regulations
Packaging Disposal: Rinse empty containers before discarding if allowed, otherwise treat as hazardous
Contaminated Materials: Dispose of gloves, wipes, and contaminated material as chemical waste
