Suitable extinguishing media: Use dry chemicals, foam, or carbon dioxide for small fires. For larger fires, use water spray or appropriate foam.
Unsuitable extinguishing media: Avoid high-pressure water jets that may spread the substance.
Fire hazards: Product may produce toxic and corrosive fumes during combustion, such as phosphorus oxides, sulfur oxides, hydrogen fluoride, and other toxic gases.
Protective equipment: Firefighters require self-contained breathing apparatus and full protective clothing.
Special procedures: Evacuate area. Prevent contaminated water from entering drains. Remain upwind.
Personal precautions: Ensure adequate ventilation. Wear chemical-resistant gloves, protective clothing, and eye protection.
Environmental precautions: Prevent further leakage or spillage. Avoid discharge into drains, surface waters, or soil.
Cleanup methods: Absorb with inert material such as sand or earth. Collect in containers for disposal. Clean spill site with detergent and water.
Advice for responders: Avoid direct contact. Remove sources of ignition.
Spill notification: Notify local authorities according to applicable regulations.
Precautions for safe handling: Handle only in well-ventilated areas. Avoid contact with skin, eyes, and clothing. Do not eat or drink in work area.
Hygiene measures: Wash hands thoroughly before breaks and after work. Remove contaminated clothing and wash before reuse.
Storage conditions: Keep container tightly closed in a dry, cool, and well-ventilated place away from incompatible materials.
Specific end use(s): For laboratory and industrial use only, not for food or pharmaceuticals.
Incompatibilities: Strong oxidizers, acids, and bases may cause hazardous reactions.
Control parameters: No occupational exposure limit established. Monitor airborne levels as part of risk assessment.
Engineering controls: Use enclosed process equipment. Provide natural or mechanical ventilation to minimize exposure.
Personal protective equipment: Chemical-resistant gloves (nitrile or neoprene), tightly sealed safety goggles, lab coat or apron. Use respiratory protection if ventilation is inadequate.
Environmental exposure controls: Prevent substance from entering water systems or soil. Apply spill control measures promptly.
Protection for maintenance personnel: Follow lock-out and decontamination procedures.

Boiling point/range: Decomposes before boiling
Flash point: Over 200°C (closed cup)
Evaporation rate: Not determined, very low
Flammability: Not classified as flammable
Vapor pressure: Low, less than 0.1 kPa at room temperature
Vapor density: Heavier than air
Relative density: 1.16–1.22 g/cm³ at 25°C

Autoignition temperature: Not established
Decomposition temperature: Above 200°C
Viscosity: Moderate at room temperature
Chemical stability: Stable under recommended storage and handling conditions.
Conditions to avoid: Excessive heat, open flames, direct sunlight, incompatibility with strong oxidizers and acids.
Materials to avoid: Strong oxidizers, acids, bases may trigger hazardous decomposition.
Hazardous decomposition products: Thermal decomposition releases toxic gases including sulfur oxides, phosphorus compounds, hydrogen fluoride, carbon monoxide, and carbon dioxide.
Polymerization: Not expected to occur.
Acute toxicity: Animal studies demonstrate moderate oral toxicity (LD50 estimation: 300–2000 mg/kg body weight in rats). Data on inhalation toxicity is limited.
Skin corrosion/irritation: Causes moderate irritation on continued exposure.
Serious eye damage/irritation: Exposure can produce noticeable eye irritation and redness.
Respiratory or skin sensitization: No clear evidence of sensitization, but repeated exposure may increase sensitivity.
Germ cell mutagenicity and carcinogenicity: No tested evidence for mutagenicity or carcinogenicity.
Reproductive toxicity: Insufficient data.
Specific target organ toxicity (single and repeated exposure): High exposures may affect liver or kidneys; more research needed.
Aspiration hazard: Not considered an aspiration hazard.
Other long-term effects: Monitor those working with the substance regularly for adverse effects.
Toxicity to aquatic organisms: Harmful or toxic to aquatic life based on analog substances and predicted ecotoxicity values (EC50 for daphnia: estimated 1–10 mg/L).
Persistence and degradability: Not readily biodegradable. Potential to persist in the environment.
Bioaccumulation potential: Moderate potential for bioaccumulation based on molecular structure.
Mobility in soil: Slight mobility expected due to ionic nature and hydrophobic chains.
Other adverse effects: Spills add extra load to aquatic systems, so immediate cleanup limits environmental harm.
Methods for disposal of waste: Dispose as hazardous chemical waste in accordance with local, regional, national, and international laws.
Disposal of containers: Rinse empty containers thoroughly before recycling, or dispose as hazardous material.
