Inhalation: Move person to fresh air, keep comfortable, seek medical attention if symptoms persist
Skin Contact: Wash with soap and plenty of water, remove contaminated clothing, seek medical help for persistent irritation
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing, get medical advice
Ingestion: Rinse mouth, do not induce vomiting, seek medical assistance immediately
Symptoms: Redness, irritation, burning sensation on skin and eyes, headache or nausea from inhalation in poorly ventilated areas
Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide, do not use water since runoff can cause environmental damage
Specific Hazards: Reacts to produce toxic and corrosive gases including hydrogen fluoride, phosphorus oxides, and hydrofluoric acid fumes
Protective Equipment for Fire-Fighters: Self-contained breathing apparatus and full protective clothing
Special Procedures: Isolate area, use water spray to cool exposed containers, approach from upwind to avoid hazardous vapors
Combustion Products: Phosphorus oxides, carbon oxides, hydrogen fluoride, other toxic gases
Personal Precautions: Evacuate unnecessary personnel, ensure adequate ventilation, use personal protective equipment including gloves, goggles, respirator
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid discharge into drains, waterways, or soil
Spill Cleanup Methods: Absorb spilled material with inert absorbent (vermiculite, sand), scoop up, place in chemical waste container, clean area with water/soap, ventilate
Reporting: Notify local authorities in case of significant leaks or contamination
Handling: Avoid direct contact with skin, eyes, or clothing, prevent inhalation of dust or vapors, operate with local exhaust or general room ventilation
Hygienic Practices: Wash hands thoroughly after use, do not eat, drink, or smoke near the product
Storage Conditions: Store in tightly closed original container, keep in a dry well-ventilated place, protect from light and moisture, store away from incompatible materials such as strong acids and bases, oxidizers
Storage Temperature: Keep at room temperature or cooler, avoid temperature extremes below freezing or above 30°C
Engineering Controls: Use fume hood or local exhaust to minimize exposure concentration, ensure safety showers, eyewash stations available
Personal Protection: Splash-proof goggles, chemical-resistant gloves (nitrile or neoprene), impervious lab coat or apron, dust mask or half-face respirator if dusty

Partition Coefficient (log Kow): Not determined
Auto-Ignition Temperature: Data not available
Decomposition Products: Releases toxic gases on decomposition
Stability: Stable under recommended storage conditions
Reactivity: Reacts with strong acids, alkalis and oxidizing agents, generates toxic HF upon reaction with acids or moisture in air
Hazardous Decomposition Products: Hydrogen fluoride, phosphorus oxides, carbon oxides, butyl compounds
Polymerization: Hazardous polymerization not expected under normal conditions
Conditions to Avoid: Excess heat, moisture, exposure to acids and oxidizers, direct sunlight
Likely Routes of Exposure: Skin and eye contact, inhalation of dust, accidental ingestion
Acute Toxicity: No specific LD50 data available, based on structural analogues expected to be of moderate toxicity
Skin Corrosion/Irritation: May cause moderate to strong irritation

Respiratory Sensitization: Not classified, may cause coughing or throat irritation
Ingestion Effects: Can lead to nausea, abdominal pain, headache, systemic toxicity if large quantities taken
Chronic Toxicity: Unlikely to accumulate, insufficient data to assess carcinogenicity or mutagenicity
Medical Conditions Aggravated: Skin disorders, existing respiratory conditions may worsen with exposure
Ecotoxicity: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Limited data, likely to resist rapid biodegradation due to ionic nature and phosphorus-fluorine bond
Bioaccumulative Potential: No significant potential to bioaccumulate expected due to molecular size and low water solubility
Mobility in Soil: Slight movement expected in soil, soluble in organic solvents but not water
Other Adverse Effects: Do not allow material to penetrate into groundwater or surface water systems, impacts not fully assessed due to limited environmental data
Waste Disposal Methods: Incinerate under controlled conditions in accordance with local regulations, small amounts can be neutralized with limestone then stabilized
Product Disposal: Avoid releasing to the environment, consult disposal company or local authority for guidance
Container Disposal: Empty containers retain residue, triple rinse and offer for recycling or reconditioning if available, or dispose under hazardous waste regulations
