Inhalation: Remove person to fresh air, seek medical attention if experiencing symptoms like dizziness or shortness of breath
Skin Contact: Remove contaminated clothing, flush skin with plenty of soap and water, seek medical help if persistent irritation appears
Eye Contact: Flush eyes with plenty of water, lift eyelids, remove contact lenses if present; keep rinsing for 15 minutes, see doctor for pain, redness, or vision changes
Ingestion: Rinse mouth, do not induce vomiting, drink water in small sips if conscious, call physician or poison control center
Most Important Symptoms: Drowsiness, nausea, headaches, irritation; large doses: kidney/liver stress, rarely methemoglobinemia; enhance monitoring for exposed children
Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, carbon dioxide; avoid direct water jet
Special Hazards: Vapors form explosive mixtures with air when heated, burns to release irritating/toxic vapors such as carbon monoxide, carbon dioxide
Protective Equipment: Wear self-contained breathing apparatus, full protective suit
Advice for Firefighters: Move containers from fire area if it can be done safely, cool containers with water spray to prevent pressure build-up, prevent runoff
Personal Protection: Use chemical-resistant gloves, splash-proof eye protection, avoid breathing vapors, evacuate unprotected personnel
Environmental Precautions: Prevent liquid from entering soil, groundwater, drains, surface water systems
Methods for Clean-up: Use absorbent materials (earth, sand, inert absorbent), collect liquid residue in closed chemical waste container, ventilate area
Spill Procedures: Clean tools and equipment after handling spill, dispose of cleanup materials according to regulatory requirements, report releases as per local rules
Handling: Use only in well-ventilated areas, avoid skin and eye contact, avoid inhaling mist/vapor, no eating, drinking, or smoking while handling
Storage: Store in tightly closed containers, keep in cool, dry, well-ventilated place away from sources of ignition, incompatible materials (strong acids, bases, oxidizers), label all containers clearly
Storage Conditions: Keep away from heat or sunlight, limit temperature fluctuations, avoid freezing
Transfer: Use grounded/bonded equipment to prevent static, use explosion-proof electrical installations in storage and transfer areas
Occupational Exposure Limits: No established ACGIH or OSHA limits, keep airborne concentrations as low as practicable
Engineering Controls: Local exhaust ventilation, mechanical general ventilation when handling large volumes
Personal Protection: Chemical resistant gloves (nitrile, neoprene), safety goggles, lab coats or aprons, protective shoes
Respiratory Equipment: Use approved organic vapor respirator if vapor concentrations exceed comfort/threshold
Hygiene: Wash hands after use, avoid touching eyes and mouth, separate storage for contaminated clothing

Viscosity: 4.8 mPa·s (20°C)
Chemical Stability: Remains stable under standard storage and transport conditions
Reactivity: Not readily reactive but reacts violently with strong oxidizing agents, strong acids, strong bases
Hazardous Reactions: Excessive heat or incompatible material contact generates decomposition products
Hazardous Decomposition Products: Carbon oxides, potentially toxic fumes

Acute Toxicity: Oral LD50 (rats): approx. 5000 mg/kg; Dermal LD50 (rabbits): approx. 7500 mg/kg; inhalation at high concentrations not well characterized
Irritation: Mild eye and skin irritation in sensitive individuals
Corrosivity: None reported
Sensitization: No sensitization seen in standard patch tests
Chronic Exposure: Long-term intensive exposure overloads filtration organs, can damage liver/kidneys; claims based on high dose animal studies

Mobility in Soil/Water: Moves easily in water, does not strongly bind to soil; potential for groundwater contamination if released in large amounts
Bioaccumulation: Low bioaccumulation potential, log Kow negative suggests unlikely build-up in animal tissue
Other Effects: Large release to water systems could alter oxygen balance due to biological demand in breakdown
