Eye Contact: Rinse eyes cautiously with water for several minutes while keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing and get medical help.
Ingestion: Rinse mouth, do not induce vomiting. Call a poison control center or physician immediately. Provide supportive care as needed.
Most Important Symptoms: Redness, pain, burning sensation, gastric upset, possible chemical burns to eyes or skin.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam. Water spray for cooling containers.
Routine Hazards: Thermal decomposition releases toxic fumes, including phosphorus oxides and hydrogen fluoride.
Special Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear to avoid contact with hazardous decomposition products.
Hazardous Combustion Products: Phosphorus oxides, toxic fluorine-containing gases, carbon monoxide, carbon dioxide.
Special Procedures: Move containers from fire area if safe. Prevent runoff into drains or waterways.
Personal Precautions: Evacuate unnecessary personnel. Wear appropriate chemical-resistant gloves, goggles, and protective clothing.
Avoid Release: Prevent product from reaching drains or entering the environment.
Spill Cleanup: Collect spillage with inert absorbent material (sand, earth, vermiculite), place in chemical waste container, and ventilate area.
Decontamination: Wash surface and tools thoroughly with water and detergent. Dispose of cleaning material under hazardous waste regulations.
Environmental Precautions: Secure spill to minimize spread. Notify relevant authorities in case of environmental contamination.
Handling: Keep containers closed and handle with care to avoid spills. Use in well-ventilated areas. Do not breathe dust, fumes, or vapors. Avoid contact with skin, eyes, and clothing. Implement good hygiene practices after handling.
Storage: Store in tightly sealed containers, away from direct sunlight and moisture. Locate in a well-ventilated, temperature-controlled area away from incompatible chemicals such as strong oxidizers and acids.
Additional Requirements: Clearly label storage containers and keep away from food and drink. Inspect containers regularly for leaks and integrity.
Exposure Limits: No established occupational exposure limits. Manage using local ventilation and general safety guidelines for similar chemicals.
Engineering Controls: Implement fume hoods or local exhaust ventilation
Personal Protective Equipment: Safety glasses or goggles, impervious gloves (nitrile or neoprene), lab coat, and suitable respiratory protection if dust or vapors may be generated.
Hygiene Practices: Avoid eating, drinking, or smoking during use. Wash hands thoroughly after handling.
Environmental Controls: Prevent release to soil, water, or public sewers by using secondary containment and monitoring systems.
Appearance: Colorless to pale yellow viscous liquid or solid
Odor: Faint, characteristic
pH: Not available (aqueous solutions may be acidic due to hydrolysis)
Melting Point: Approx. 35-40°C
Boiling Point: Decomposes before boiling
Flash Point: > 150°C (closed cup, estimated)
Solubility: Slightly soluble in water, highly soluble in organic solvents
Partition Coefficient (log Pow): Not determined
Vapor Pressure: Very low at ambient conditions
Viscosity: High, depending on temperature
Decomposition Temperature: Decomposes above 200°C
Density: Approx. 1.1-1.2 g/cm³
Auto-ignition Temperature: Not available
Chemical Stability: Remains stable under recommended storage and handling conditions. Degrades at elevated temperatures, producing toxic gases.
Incompatible Materials: Strong oxidizing agents, mineral acids, bases, materials that might release fluoride ions
Hazardous Decomposition Products: Hydrogen fluoride, phosphorus oxides, carbon monoxide, carbon dioxide
Polymerization: Not known to undergo hazardous polymerizations
Additional Considerations: Moisture and heat accelerate decomposition. Avoid conditions that favor hydrolysis.
Acute Toxicity: Harmful if ingested, inhaled, or absorbed through skin. Limited data on lethal doses; based on related phosphonium salts, suspected oral LD50 in rats: 500-2000 mg/kg.
Irritation: Causes skin and eye irritation. Repeated or prolonged exposure increases risk of dermatitis or serious eye damage.
Sensitization: Could sensitize skin upon repeated contact.
Carcinogenicity: No evidence from available data. Contains no listed carcinogens by OSHA, IARC, or NTP.
Mutagenicity: No clear information, but organofluorophosphonium salts pose potential genetic hazards.
Other Effects: May cause respiratory tract irritation if dust or vapor is inhaled.
Ecotoxicity: Limited data available; similar fluorinated phosphonium compounds can be toxic to aquatic organisms.
Persistence and Degradability: Not rapidly biodegradable; likely to persist in soil and sediment. Products may degrade to release persistent phosphorus and fluorinated species.
Bioaccumulation: Potential for bioaccumulation in aquatic systems due to moderate lipophilicity and slow breakdown.
Mobility in Soil: Based on solubility, can migrate to groundwater; strong sorption to organic content in soils.
Other Adverse Effects: No data, but minimize release; harm to aquatic life and soil microorganisms probable.
Regulatory Status: Not listed as a marine pollutant, but local environmental laws may apply.
Waste Treatment Methods: Dispose of product in accordance with local, regional, and national regulations. Seek specialized facilities qualified to handle hazardous chemical waste.
Contaminated Packaging: Dispose similarly; do not reuse containers. Rinse empty containers with suitable solvent and send for chemical waste incineration.
Special Precautions: Do not dump into environment. Confirm disposal methods with regulatory agencies.
Regulatory Information: Waste code may vary by jurisdiction, but typically assigned hazardous waste status.
Recommended Disposal: Incineration at high temperatures with scrubbers for toxic gases.
UN Number: Not assigned (consult latest ADR, IMDG, IATA rules for updates)
Proper Shipping Name: Organophosphorus compound, n.o.s. (not otherwise specified); consult shipping regulations
Hazard Class: May not be classified under current transport regulations, but treat as chemical hazard
Packing Group: III (recommended, based on toxicity and chemical nature)
