Symptoms to Watch For: Burning, redness, coughing, headaches
Suitable Extinguishing Media: Carbon dioxide, dry chemical extinguisher, foam, water spray in small amounts
Unsuitable Media: High-pressure water jets can cause product spread
Fire Hazards: Decomposition forms toxic vapors including sulfur oxides, toluene energy products, and low levels of carbon monoxide
Protective Equipment: Wear self-contained breathing apparatus, full protective gear including face shield
Special Exposure Risks: Minimize inhalation of combustion by-products, ventilate area
Further Actions: Move containers from fire site if safe, cool with water mist if overheating occurs
Personal Protection: Put on chemical-proof gloves, safety goggles, and apron before touching spilled material
Environmental Precautions: Block drains, keep away from soil or surface water, minimize spread with absorptive barriers
Methods for Clean-Up: Absorb with sand, earth, or commercial spill kit, collect in secure, labeled chemical waste container
Decontamination: Wash affected area with detergent and water, ventilate after completion
Reporting: Notify appropriate local environmental agencies or regulatory bodies if major spill escapes secondary containment
Handling: Use only with adequate ventilation, avoid all unnecessary exposure or inhalation, never eat, drink, or smoke near chemical handling zones, always seal container after transfer
Storage Conditions: Store at room temperature, keep away from direct sunlight and incompatible materials (especially strong bases, oxidizers, strong acids), tightly close containers when not in use
Container Specifications: Chemically resistant poly or glass preferred, no metal contact
Safe Transfer Tips: Use anti-static grounding where possible, drip trays suggested beneath fixed dispensing pumps
Incompatibilities: Avoid storage near oxidizers, moisture-susceptible goods, or acids
Exposure Limits: No established long-term workplace exposure limit, treat as a moderate irritant
Engineering Controls: Local exhaust ventilation, fume hoods for large decanting
Personal Protective Equipment (PPE): Impervious gloves (nitrile, neoprene), chemical splash goggles, lab coats or full aprons, proper footwear
Respiratory Protection: Use a NIOSH-approved half-mask respirator with organic vapor cartridge if vapor present or large spill occurs
Hygiene Measures: Wash hands and forearms after use, keep contaminated garments separate until cleaned
Appearance: Clear to pale yellow oily liquid or crystalline solid at cooler temperatures
Odor: Mild, faint, slightly aromatic
Odor threshold: Low, not strongly perceptible
pH: Neutral to slightly acidic in water
Melting/Freezing Point: Low melting (approx. 30-40°C depending on grade)
Boiling Point: Above 230°C
Flash Point: Approx. 140°C (closed cup)
Flammability: Not highly flammable, may burn if heated above flash point
Vapor Pressure: Extremely low at room temperature
Solubility: Miscible in water, alcohols, glycol ethers
Density: 1.30–1.35 g/cm³ (varies with temperature)
Partition Coefficient (log Kow): Not available in public literature
Viscosity: Moderate
Chemical Stability: Stable under recommended storage conditions; decomposition begins at sustained temperatures above 160°C
Reactions: Vigorous reaction with strong oxidizers, may hydrolyze slowly in strong alkalis
Hazardous Decomposition Products: Sulfur dioxide, toluene, low levels of phenol, carbon monoxide, carbon dioxide
Polymerization: Not expected
Conditions to Avoid: Excess heat, open flames, strong UV exposure, mixing with incompatible reagents
Acute Toxicity: Low to moderate; estimated oral LD50 (rat) > 2,000 mg/kg
Skin Corrosion/Irritation: May cause redness, especially with prolonged or repeated exposure
Eye Damage/Irritation: Moderate irritant; severe cases require medical attention if symptoms persist
Respiratory Sensitization: Unlikely from single exposure, but repeated inhalation could trigger irritation
Carcinogenicity: No long-term cancer studies completed; not classified as a known carcinogen
Mutagenicity/Reproductive Toxicity: No evidence found for mutagenic or reproductive impacts in current studies
Additional Effects: Slight headache, nausea after large dose exposure, no specific target organ toxicity expected in occasional use
Aquatic Toxicity: Possible mild toxicity for aquatic life due to sulfonate group, detailed LC50 data not widely published
Persistence/Degradability: Expected to hydrolyze and biodegrade under aerobic conditions, breakdown may be slow in cold soil or sediment
Mobility: High in water; likely to mix into surface runoff
Bioaccumulation: Unlikely, no known significant build-up in aquatic food chains
Other Environmental Issues: Large spills can upset local sewage treatment processes, so limit volume entering municipal drains as far as possible
Waste Handling: Collect all spilled waste into chemical disposal drums with clear labeling
Disposal Method: Send well-sealed waste containers to licensed chemical disposal companies specializing in organic esters or industrial sulfonates
Empty Packaging: Triple-rinse and puncture before landfilling or recycling in approved, controlled sites
Additional Notes: Never dump into natural waterways, residential trash, or sewers; check for any updates on local landfill or incineration guidelines
UN Number: Not widely classified under common UN codes (consult shipment documentation, as rules change periodically)
Proper Shipping Name: Propanedioldiptoluenesulfonate or related sulfonic acid ester
Transport Hazard Class: Not regulated for land, air, or sea under general conditions, but transporter must verify latest hazardous goods listings
Packing Group: Not assigned (typical for low acute toxicity chemicals)
