Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, water spray
Unsuitable Extinguishing Media: Direct water jet may spread burning liquid
Special Hazards: Emits toxic fumes including phenol compounds and carbon oxides when heated strongly or during combustion; closed containers may rupture if exposed to flames or high heat
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective clothing recommended due to risk of fume inhalation
Additional Advice: Stand upwind of fire; prevent runoff from reaching open drains or waterways
Personal Precautions: Wear chemical-resistant gloves, goggles, and splash apron; ventilate area; avoid generation of dust or vapor
Environmental Precautions: Keep spills out of watercourses and sewers; notify authorities if major release threatens ecosystem
Cleanup Methods: Absorb liquid with inert material such as sand or earth; shovel into waste container; clean residue with water and suitable detergent; dispose of in accordance with local regulations
Spill Volume Control: Contain spill with dikes if large; neutralize if advised by qualified personnel
Handling: Use local exhaust ventilation to limit airborne concentrations; keep containers tightly closed when not in use; avoid contact with eyes, skin, clothing
Safe Handling Practices: Do not eat, drink, or smoke while handling; always wash thoroughly after handling; use proper grounding for transfer operations
Storage Conditions: Store in a dry, cool, well-ventilated facility away from heat and direct sunlight; keep in original, labeled container; segregate from incompatible chemicals such as strong oxidizing agents
Packaging Materials: Use corrosion-resistant containers designed for organic chemicals
Exposure Limit Values: No workplace exposure limit established by OSHA or ACGIH; caution is advised due to irritation risk
Engineering Controls: Local exhaust, general dilution ventilation recommended to keep vapor concentrations below 5 ppm for comfort
Personal Protective Equipment (PPE): Chemical splash goggles, gloves made from nitrile or neoprene, long-sleeved protective clothing, face shield for risk of splashing; if exposure limit risk exists, use respirator with organic vapor cartridge
Hygiene Measures: Remove contaminated clothing; wash skin thoroughly after exposure; clean equipment regularly
Appearance: Colorless to pale yellow, viscous liquid
Odor: Mild, slightly phenolic odor
pH (undiluted): Not applicable, non-aqueous liquid

Vapor Pressure: Less than 1 mm Hg at 20°C
Vapor Density: Heavier than air
Solubility in Water: Slightly soluble (estimated under 10 g/L)
Partition Coefficient (Log Kow): Estimated range between 1.5–2.5; affinity for organic phases
Autoignition Temperature: Around 350°C
Decomposition Temperature: Decomposes above 180°C
Viscosity: Viscous at ambient temperatures

Possible Reactions: Can react with strong oxidizing agents, acyl halides, acid chlorides; hazardous polymerization not expected
Decomposition Products: Phenol compounds, carbon monoxide, carbon dioxide may form in fire conditions
Conditions to Avoid: Avoid exposure to open flames, sparks, excessive heat, and strong oxidizers
Routes of Exposure: Eyes, skin, inhalation, ingestion
Acute Effects: Eye and skin irritation; inhalation of vapor may cause respiratory tract discomfort; ingestion likely to cause stomach upset, possible drowsiness or dizziness
Chronic Effects: No clear evidence of carcinogenicity or reproductive toxicity in available studies; may aggravate pre-existing skin or respiratory conditions
Toxicity Data: Oral LD50 (rat) estimated at greater than 2,000 mg/kg; skin and eye irritation studies show mild to moderate irritation at high concentrations
Sensitization: Not known to produce allergic effects
Aquatic Toxicity: Expected to be moderately toxic to aquatic organisms, with EC50 values in the low to mid mg/L range for fish and daphnia based on structure-activity studies
Persistence and Degradability: Partial biodegradability under aerobic conditions; likely to persist in low-oxygen waters
Bioaccumulation Potential: Moderate due to log Kow between 1.5–2.5; not highly persistent in higher organisms
Soil Mobility: Low mobility; will adsorb moderately to soil organic matter
Other Hazardous Effects: Possible environmental hazard at high concentrations or in cases of large spills
Waste Disposal Methods: Dispose of by incineration in a chemical incinerator equipped with afterburner and scrubber in accordance with local and national regulatory requirements; avoid release to waterways
