Impurities: Typical samples may include small amounts of other hydrocarbons, usually less than 1%
Inhalation: Remove person to fresh air, keep comfortable for breathing, seek medical attention for severe symptoms
Skin Contact: Remove contaminated clothing, rinse skin with water for at least 15 minutes, seek medical attention for irritation
Eye Contact: Flush with water for at least 15 minutes, hold eyelids open, obtain medical care if discomfort continues
Ingestion: Do not induce vomiting, rinse mouth with water, seek immediate medical attention due to aspiration risk
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide (CO2), water spray to cool containers
Specific Hazards: Vapors can travel to a source of ignition distant from the handling point, may form explosive mixtures with air; burns with invisible flame
Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Firefighting Procedures: Evacuate area, use water spray to keep exposed containers cool, control run-off water, avoid breathing combustion gases
Personal Precautions: Remove ignition sources, ventilate area, avoid contact with spilled material, use protective equipment including gloves and goggles
Environmental Precautions: Prevent entry into drains, sewers, and waterways; notify authorities if significant release or contamination occurs
Containment Methods: Stop leak if safe to do so, contain spill with inert material like sand or earth; do not allow material to dry and become airborne
Clean-Up: Use non-sparking tools, transfer spill to appropriate labeled containers, dispose according to local regulations
Handling: Use only in well-ventilated areas, avoid inhalation and contact with skin or eyes, do not smoke or use ignition sources
Storage: Store tightly closed in a cool, dry, well-ventilated location designated for flammable chemicals, segregate from oxidizing and reactive materials, ground and bond containers, label storage areas clearly
Special Instructions: Maintain good hygiene practices, clean spills immediately, do not reuse empty containers
Occupational Exposure Limits: OSHA TWA: 500 ppm; ACGIH TWA: 300 ppm
Engineering Controls: Local exhaust ventilation required where vapors are generated; safety shower and eyewash stations
Personal Protection: Chemical safety goggles, flame-resistant gloves, splash-proof aprons for handling, flame-proof antistatic footwear, organic vapor respirator if ventilation is inadequate
General Safety Measures: Remove contaminated clothing immediately, wash hands before eating or drinking, keep food and beverages out of the work area

Viscosity: 0.508 mPa·s at 20°C
Molecular Weight: 114.23 g/mol
Chemical Stability: Stable under recommended handling and storage conditions
Reactivity: Not reactive under normal conditions
Conditions to Avoid: Heat, sparks, open flames, strong oxidizers, static discharge
Incompatible Materials: Oxidizing agents, acids, halogens
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, various hydrocarbons
Acute Toxicity: Oral LD50 (rat): 12,800 mg/kg; inhalation LC50 (rat): 13,000 ppm/4 hr
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Symptoms: Drowsiness, headache, nausea, dizziness, narcosis at high exposure levels
Chronic Effects: Prolonged or repeated exposure can cause dermatitis, central nervous system effects
Carcinogenicity: Not classified as a human carcinogen by IARC, NTP, OSHA
Mutagenicity/Teratogenicity: No data indicating mutagenic or teratogenic effects in humans
Target Organs: Central nervous system, skin, respiratory system
Other Effects: Aspiration into the lungs during ingestion or vomiting may cause chemical pneumonitis, a potentially fatal condition
Aquatic Toxicity: Low solubility makes persistence likely in aquatic environments; fish 96 hr LC50 (rainbow trout): estimated 5.7 mg/L
Persistence and Degradability: Slowly biodegradable, can volatilize from soil and water surfaces, low potential for bioaccumulation due to high log Kow
Bioaccumulative Potential: High (log Kow > 6)
Mobility in Soil: Low due to poor water solubility and high volatility
Other Adverse Effects: May cause contamination if released to waterways, toxic to aquatic organisms at elevated concentrations, avoid uncontrolled discharge into the environment
Waste Disposal Methods: Dispose of contents/container in accordance with local/national regulations using licensed waste disposal contractors
Disposal of Contaminated Packaging: Rinse and destroy containers, never reuse for food or drink
Special Precautions: Do not allow to enter sewers, ground, or water bodies; incineration is preferred treatment method for bulk waste
