Fire and Explosion Hazards: Dust generation increases explosion risk, avoid accumulation
Advice for Firefighters: Keep people away, cool containers with water, prevent run-off contaminating waterways, evacuate area if large-scale fire occurs
Personal Precautions: Avoid breathing dust, ventilate area, wear protective gloves, goggles, and mask
Methods for Cleanup: Scoop or vacuum up spill, avoid creating dust, place in labeled waste container, wash area with water/detergent
Environmental Precautions: Prevent entry into drains, surface water, or soil
Emergency Procedures: Evacuate unprotected personnel, isolate area, provide fresh air
Waste Disposal: Follow local, regional, and national guidelines for hazardous waste handling
Precautions for Handling: Keep container tightly closed, avoid dust formation, handle in fume hood if possible, use grounding and bonding when transferring larger amounts
Precautions for Storage: Store in a cool, dry, well-ventilated area, away from moisture and incompatible substances such as strong bases or acids
Incompatible Materials: Strong oxidants, moisture, acids, bases
Specific Use Notes: Label area with chemical hazards, minimize handling without protection, prevent skin and eye contact
Occupational Exposure Limits: No specific national or ACGIH exposure limit established for this compound
Engineering Controls: Local exhaust ventilation, process enclosure, appropriate chemical fume hood
Protective Equipment: Safety glasses with side shields, chemical-resistant gloves (nitrile or neoprene), lab coat or apron, dust mask or respirator (N95 minimum)
Personal Hygiene: Wash hands after handling, remove contaminated clothing, avoid eating or drinking around chemical
Environmental Exposure Prevention: Prevent release into environment through containment or use of spill trays
Appearance: White to off-white powder or waxy solid
Odor: Mild, slightly musty organic odor
pH: Not determined (expected near neutral in water)
Melting Point: 65 – 80°C
Boiling Point: Decomposes before boiling
Flash Point: >120°C (closed cup, estimated)
Solubility: Sparingly soluble in water, highly soluble in polar organic solvents
Vapor Pressure: Very low
Partition Coefficient: High log Kow (strong hydrophobicity)
Stability in Solution: May hydrolyze in humid environments
Density: About 1.0 – 1.2 g/cm³ at 25°C
Chemical Stability: Stable under standard laboratory conditions, degrades gradually on exposure to air moisture
Conditions to Avoid: Humidity, extreme heat, direct sunlight
Incompatible Materials: Strong acids, bases, oxidizers, moisture
Decomposition Products: May release hydrogen fluoride, phosphorus oxides, toxic fumes under fire
Reactivity Notes: May react with water to form hydrofluoric acid, moderate hazard from fluoride release
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Toxicity: LD50 (oral, rat) > 200 mg/kg (data from structural analogs)
Skin Corrosion/Irritation: Causes irritation, redness, itching
Eye Damage/Irritation: Strong irritant, risk of serious eye injury
Respiratory Sensitization: Coughing, shortness of breath on inhalation of dust
Chronic Effects: No known long-term studies, repeated exposure can aggravate respiratory or skin conditions
Mutagenicity/Carcinogenicity: No valid study data, not listed as a carcinogen by IARC, NTP, or OSHA
Other Information: Prolonged contact increases likelihood of symptoms, personal protection is important
Ecotoxicity: Potentially toxic to aquatic organisms, due to persistence and bioaccumulation
Persistence and Degradability: Does not readily biodegrade, breaks down slowly in environment
Bioaccumulative Potential: Very high due to long alkyl chain
Mobility in Soil: Low mobility, binds strongly to soil and sediment
Other Adverse Effects: Risk of long-term effects on aquatic environment if spilled
Precautions: Prevent release to surface water, ensure proper waste containment
Disposal Methods: Incinerate in approved chemical waste facility, do not dispose of via drains
Container Disposal: Rinse empty containers with suitable solvent, treat rinse as hazardous waste
Compliance: Follow EPA, local/state/provincial, and international regulations
Special Precautions for Landfill: Not suitable for landfill, avoid landfill disposal
Waste Classification: Treat as hazardous due to potential release of fluoride and persistent organic pollutant nature
