Additional Information: May include non-hazardous additives and stabilizers, which are typically proprietary or considered non-hazardous under OSHA guidelines
Inhalation: Move affected person to fresh air immediately; keep warm and at rest; seek medical attention if symptoms such as coughing or chest discomfort persist
Skin Contact: Remove contaminated clothing and wash skin thoroughly with soap and water; do not use solvents or thinners
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes while holding eyelids open; remove contact lenses if present and easy to do; consult a physician
Ingestion: Rinse mouth with water; never induce vomiting; provide small sips of water if the person is conscious; obtain medical help right away
Symptoms and Effects: Short-term exposure may cause redness, irritation, coughing; long-term or repeated contact may cause organ damage or neurological effects
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray; use media suitable for surrounding materials as well
Special Hazards: May decompose under fire conditions emitting toxic phosphorous oxides, carbon oxides, and hydrogen chloride gases
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Firefighting Instructions: Cool containers exposed to fire with water spray; control run-off water; avoid direct entry into drains or waterways
Personal Precautions: Avoid direct contact with skin, eyes, and clothing; ensure adequate ventilation; use recommended personal protective equipment
Environmental Precautions: Prevent product from entering drains, sewers, or watercourses due to risk of environmental harm
Containment and Cleanup: For small spills, absorb with inert material (sand, earth); collect in suitable, closed containers for disposal; for large spills, use diking or barriers to stop spread; clean contaminated area with water and detergent
Reference to Other Sections: See information on exposure controls and personal protection
Safe Handling: Avoid inhalation of vapors or dust; minimize contact with skin and eyes; use in well-ventilated areas; never consume food or drink or smoke while handling
Storage Conditions: Store containers tightly closed in a dry, cool, well-ventilated area; keep away from sources of ignition, heat, and direct sunlight; do not store with incompatible materials such as strong oxidizers or strong acids
Incompatibilities: Strong acids, oxidizing agents, strong bases
Other Considerations: Use original containers if possible; label all secondary containers clearly
Exposure Limits: No established OSHA PEL; ACGIH TLV for related compounds is typically 3 mg/m³ (inhalable fraction)
Engineering Controls: Use local exhaust ventilation or general dilution ventilation to keep airborne concentrations below recommended limits; use explosion-proof equipment in areas with potential vapor build-up
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or butyl), safety goggles or face shield, protective clothing to minimize skin contact; in case of insufficient ventilation, use suitable respiratory protection (organic vapor cartridge respirator)
Workplace Hygiene: Wash hands and face after handling; do not eat, drink, or smoke in work areas
Physical State: Liquid or viscous fluid, sometimes crystalline solid depending on specific grade
Color: Colorless to pale yellow
Odor: Mild, slightly aromatic or chemical
pH: Not applicable or slightly acidic in aqueous solutions
Boiling Point: 400°C (752°F) range depending on type
Melting Point: -40°C to 50°C, depending on component
Density: 1.1–1.4 g/cm³
Solubility: Poorly soluble in water; soluble in most organic solvents
Vapor Pressure: Low, below 1 mmHg at 25°C
Flash Point: > 230°C (closed cup)
Partition Coefficient (log Kow): 4–7
Chemical Stability: Stable under normal use and storage conditions
Conditions to Avoid: Avoid heat, sparks, open flames, direct sunlight, and moisture
Incompatible Materials: Strong oxidizers, strong acids or bases, aluminum
Decomposition Products: Decomposition at high temperatures can generate carbon oxides, phosphorus oxides, hydrogen chloride, and other toxic gases
Hazardous Reactions: Risk of hazardous polymerization is low
Routes of Exposure: Contact with skin or eyes, inhalation of vapors, dust, or mists, ingestion
Acute Toxicity: LD50 (oral, rat) ~2,000–5,000 mg/kg depending on type
Skin Irritation: May cause redness and irritation
Eye Irritation: Causes moderate irritation with tearing, redness
Chronic Effects: Repeated or prolonged exposure may affect liver, kidneys, or nervous system
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA, but some related compounds have been under review
Other Health Effects: Reports of reproductive toxicity and developmental toxicity for certain phosphate esters (e.g., TCEP)
Aquatic Toxicity: Very toxic to aquatic organisms; may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Partially biodegradable but may persist in sediments and water, potentially biomagnifying in the food chain
Bioaccumulation: Significant potential for accumulation in aquatic organisms
Mobility in Soil: Low to moderate; may leach to some extent but tends to stick to sediments and organic matter
Other Effects: Phosphate esters can have chronic effects at low concentrations for certain fish and invertebrate species
Waste Treatment Methods: Collect and contain material for proper disposal; do not dump into drains or the environment
Disposal of Containers: Empty containers thoroughly to remove residues, then send to approved recycler or incinerator
Hazardous Waste: Classified as hazardous waste under RCRA; generate and dispose in accordance with local, state, and federal regulations
Precautions: Avoid incineration without properly equipped pollution controls due to possible emission of toxic gases
