Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (avoid direct jet of water on burning product)
Special Hazards: Releases toxic gases under fire conditions such as phosphorus oxides, carbon monoxide
Protective Equipment: Full protective gear, self-contained breathing apparatus and gloves required for responders
Advice for Firefighters: Keep upwind, stay out of low areas, cool nearby containers with water spray to keep product stable
Explosion Risk: Product can fume but doesn’t usually explode unless heated in closed drums
Hazards to Nearby Materials: Shouldn’t mix with acids, oxidizers or bases during fire response
Personal Protection: Put on gloves, goggles, and protective aprons to block skin and eye exposures
Environmental Precautions: Block material from drains, stormwater, or water pipes due to aquatic toxicity
Containment: Dike and soak up spill with sand, absorbent pads or clay, bag up contaminated material in tight drums for picking up
Cleanup Procedures: Clean spill area with industrial detergent and large amounts of water once bulk is picked up
Ventilation: Open doors or windows, use fans to reduce harmful air levels in enclosed spots
Disposal: Waste and cleanup material must be labeled hazardous and disposed of by licensed contractor in accordance with regulations
Handling Practices: Always wear gloves, goggles, and coveralls; avoid breathing dust, vapor or mist; wash hands after
Storage Conditions: Keep containers tightly closed, store at 5-30°C, away from food and drink
Incompatible Materials: Store away from oxidizers, acids, strong bases or aluminum
Other Precautions: Use in well-ventilated places to limit buildup of fumes; keep drums shut when not in use
Long-Term Storage: Avoid freezing or overheating; shelf life usually is one year in original packaging
Packaging: Use lined drums, HDPE or composite containers
Engineering Controls: Local exhaust ventilation, splash-proof work areas, eyewash stations needed in all use locations
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), chemical goggles and face shield, disposable coveralls or apron
Respiratory Protection: Mask or respirator if vapor/dust levels go above recommended limits
Exposure Limits: No strict OSHA PEL set, but keep airborne levels as low as possible
Environmental Controls: Procedures in place to block leaks, use sump or drain covers under storage racks
Appearance: Clear or slightly yellowish viscous liquid
Odor: Mild, faint organic smell
pH (undiluted): Around 2.5 - 3.5
Boiling Point: Above 200°C
Melting Point: Below 0°C, usually does not freeze at room temperature
Flash Point: More than 110°C, not considered highly flammable
Vapor Pressure: Very low at room temperature
Specific Gravity: 1.35 - 1.40
Solubility: Miscible with water, limited in organic solvents
Decomposition Temperature: Starts to break down above 240°C, letting off phosphorus oxides
Viscosity: High – thick liquid
Evaporation Rate: Slow
Chemical Stability: Stable under normal storage and handling
Reactivity: Can react with strong acids, bases, and oxidants
Decomposition Products: Burning, charring, or overheating releases phosphorus oxides and hydrocarbons
Hazardous Reactions: May polymerize if mixed with incompatible chemicals or exposed to sunlight
Conditions to Avoid: High heat over long periods, mixing with strong oxidizers, storing in metal containers can trigger reactions
Incompatible Materials: Avoid acids, bases, oxidizers, and metals like aluminum or zinc
Acute Toxicity: Causes burns, mouth and throat pain if swallowed; moderate toxicity through skin or inhalation
Chronic Effects: Prolonged skin contact may lead to dermatitis; inhalation can cause upper airway effects
Sensitization: Not a skin sensitizer based on limited animal data
Relevant Routes of Exposure: Eyes, skin, mouth and lung; fumes can make symptoms worse in asthma
Carcinogenicity/Mutagenicity: No evidence of cancer or genetic risk in published literature
Other Risks: May aggravate eczema or respiratory disease if inhaled frequently at high doses
Symptoms of Overexposure: Burning, irritation, nausea, dizziness
Ecotoxicity: Harmful to aquatic organisms or plants; may cause longer-term effects if spills reach water
Persistence: Phosphonates tend to remain in soils and sediments for months if not physically removed
Bioaccumulation: Low potential to build up in fish or food chains
Mobility: Moves with water, but binds to soils and organic matter
Degradability: Breaks down slowly through microbial action in well-managed landfills and water treatment
Disposal Concerns: Never pour to surface water or public sewers without treatment
Preferred Disposal: Take to hazardous chemical incinerator authorized for phosphorus compounds
Container Disposal: Clean empty containers with water and detergent, puncture to prevent reuse; send for industrial recycling
Special Instructions: Label all waste, complete a hazardous waste manifest if needed, store in well-marked drums
Avoid: Landfilling untreated liquid or mixed with household waste
Supplier Take-Back: Some manufacturers run closed loop take-back for used drums
