Notes to Physician: Treatment based on symptoms, consider observation for delayed effects in case of significant exposure
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, water spray
Specific Hazards: Combustion releases toxic and corrosive fumes, risk of phosphorus oxides, possible flashback
Protective Equipment: Full protective gear, self-contained breathing apparatus for fire-fighters
Special Procedures: Cool fire-exposed tanks with water spray, avoid inhaling smoke
Explosion Data: Not particularly sensitive to mechanical impact or static discharge but can form flammable mixtures when vaporized
Fire Residues: Toxic, proper containment and clean-up required after a fire
Personal Precautions: Use appropriate personal protective equipment, ensure adequate ventilation, isolate area
Environmental Precautions: Prevent spillage from entering drains, surface and groundwater; notify authorities in case of large spill
Methods for Cleanup: Absorb with inert material (sand, earth, vermiculite), collect and place in suitable containers for disposal
Decontamination: Wash with copious amounts of water and mild detergent after cleanup
Disposal of Cleanup Materials: Seal in labeled, approved waste containers for hazardous materials
Spill Area Ventilation: Ensure maximum possible air flow until all residue is removed and area is declared safe
Handling: Avoid breathing vapors or mist, avoid skin and eye contact, keep away from heat, sparks, and open flames, wash hands after handling
Storage: Store in a tightly closed container, in a cool, dry, well-ventilated area, away from incompatible materials such as strong oxidizers and acids
Storage Temperature: Maintain below 30°C, do not freeze
Packaging: Preferably in high-density polyethylene drums or steel containers compatible with organic phosphates
Special Designation: Storage area should include secondary containment to prevent leaks spreading
Occupational Exposure Limit: 0.1 mg/m³ (manufacturer recommendation, check local regulations)
Engineering Controls: Work in well-ventilated environments, use fume hoods or extraction fans
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles, lab coat or coveralls, appropriate respiratory protection in poorly ventilated areas
Hygiene Measures: Wash thoroughly after handling, do not eat or drink in work areas
Biological Monitoring: Regular urinary or blood testing for workers at risk of chronic exposure
Appearance: Clear, colorless to pale yellow liquid
Odor: Faint, aromatic
Boiling Point: 400–420°C
Melting Point: Lower than room temperature, remains liquid
Density: 1.18–1.20 g/cm³ at 25°C
Solubility: Insoluble in water, soluble in most organic solvents
Vapor Pressure: Very low at room temperature (<0.01 mmHg)
Flash Point: 235°C (closed cup)
Auto-ignition Temperature: 430°C
Viscosity: Moderate, thick liquid at room temperature
Partition Coefficient (log Kow): Estimated >4 (high potential for bioaccumulation)
Chemical Stability: Stable under normal storage and usage conditions
Incompatibilities: Strong oxidizing agents, strong acids, alkalis, reducing agents
Conditions to Avoid: Excessive heat, sparks, open flames, moisture
Hazardous Decomposition Products: Phosphorus oxides, aromatic hydrocarbons, irritant fumes
Reactivity: Not expected to polymerize, but thermal decomposition can generate hazardous vapors
Shelf Life: Typically several years in properly sealed containers in cool storage
Routes of Exposure: Absorption through skin, inhalation of vapor or mists, accidental ingestion
Acute Toxicity: LD50 (oral, rat) 2700 mg/kg; LD50 (dermal, rabbit) 6500 mg/kg
Skin Corrosion/Irritation: Causes redness, dryness, sometimes burns on prolonged contact
Eye Damage/Irritation: Causes severe eye irritation, redness, watering
Respiratory Sensitization: Signs include coughing, headaches with moderate exposure
Chronic Effects: Potential neurotoxicity with prolonged or repeated exposure; possible effects on liver and kidneys
Carcinogenicity: Not listed as a known carcinogen by IARC, ACGIH, or NTP
Mutagenicity: Genetic toxicity studies indicate low mutagenic risk
Other Adverse Effects: Allergic skin reactions possible in sensitive individuals
Ecotoxicity: Highly toxic to aquatic organisms; LC50 (fish) ~2 mg/L (96h)
Persistence and Degradability: Poorly biodegradable, may persist in sediment and water
Bioaccumulation Potential: High log Kow, likely to accumulate in aquatic organisms
Mobility in Soil: Strongly adsorbs to soil and organic matter, unlikely to leach into groundwater
Other Adverse Effects: Potential to disrupt aquatic food chains through bioaccumulation
Recommendations: Prevent material from entering waterways, avoid large-scale release into the environment
Waste Treatment Methods: Incineration in facilities equipped to handle organophosphates, do not landfill untreated product
Container Disposal: Triple rinse containers, puncture, and dispose of according to local, state, and federal regulations
Disposal of Small Quantities: Absorb spills with inert material and incinerate in chemical incinerator
