Inhalation: Move to fresh air and monitor consciousness, loosen tight clothing, seek medical attention for persistent headache, coughing, or dizziness
Skin Contact: Remove contaminated clothing, wash area thoroughly with soapy water, use moisturizer if skin dries or cracks, medical help for lasting redness or rash
Eye Contact: Immediately rinse eyes gently with water for at least twenty minutes, hold eyelids apart, avoid rubbing, consult medical if symptoms like pain or blurred vision linger
Ingestion: Rinse mouth, do not induce vomiting, drink water if fully alert, monitor for symptoms such as nausea, drowsiness, confusion, call poison control right away
Advice for Doctor: Treat symptomatically, monitor for respiratory distress or chemical pneumonia, especially in severe inhalation cases
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide
Unsuitable Media: Steer clear of high-pressure water streams as they may spread fire
Special Hazards: Vapors form explosive mixtures with air, containers exposed to fire may rupture, decomposition can release irritating fumes such as carbon monoxide and carbon dioxide
Protective Equipment: Full protective gear and self-contained breathing apparatus required to prevent exposure to fumes
Firefighting Guidance: Evacuate area, cool containers uncovered by fire from a safe distance, prevent run-off from contaminating sewers or waterways
Personal Precautions: Ventilate area, restrict unnecessary access, eliminate ignition sources, avoid inhaling vapors
Spill Cleanup: Absorb with inert dry material like sand or vermiculite, collect in suitable closed containers for disposal, clean remainder with non-sparking tools
Environmental Precautions: Prevent entry into drains, soil, and water bodies, inform authorities if significant spill threatens environment
Disposal Method: Label containers appropriately for hazardous solvent disposal based on local guidelines
Safe Handling: Use with adequate physical ventilation, avoid breathing mist or vapor, practice good chemical hygiene, do not eat, drink, or smoke during use
Storage Conditions: Store in tightly closed containers, keep away from heat, sparks, static electricity, or direct sunlight in dedicated flammable storage cabinets
Incompatible Materials: Strong oxidizers, acids, and bases can cause dangerous reactions, never store with food or in open air
Handling Advice: Employ grounding and bonding for bulk transfer, ensure all electrical equipment is rated for flammable environments
Exposure Limits: OSHA PEL not established for this solvent, refer to manufacturer or ACGIH TLV values for recommended airborne limits (often <50 ppm over 8-hour work period)
Engineering Controls: Use local exhaust ventilation, forced-air systems in closed rooms, explosion-proof equipment
Personal Protection Equipment (PPE): Chemical goggles or safety glasses, nitrile gloves, apron for splash risk, flame-resistant lab coats, respiratory protection like organic vapor cartridges in low-ventilation work zones
Hygiene Measures: Wash hands after handling, no food or drink in chemical use areas, change contaminated clothes
Appearance: Clear, colorless liquid

Melting Point: Below -70°C
Boiling Point: 135–140°C
Flash Point: Around 45°C (closed cup)
Evaporation Rate: Slower than diethyl ether
Flammability: Flammable liquid (per GHS criteria)
Vapor Pressure: About 5 mmHg at 20°C
Vapor Density: Heavier than air (2.5)
Relative Density: Approximately 0.87 (water = 1)
Solubility: Miscible with water and alcohols
Partition Coefficient (n-octanol/water): Moderate (log Kow ~ 0.3)
Auto-ignition Temperature: 265–300°C
Decomposition Temperature: Above 200°C with breakdown products
Viscosity: Low (liquid spreads easily at room temperature)
Chemical Stability: Stable in sealed containers at standard laboratory storage temperatures
Reactivity Profile: Avoids contact with strong oxidizers, acids, bases — may lead to violent decomposition
Hazardous Reactions: May polymerize or react exothermically with hazardous chemicals, risk of runaway if mixed carelessly
Hazardous Decomposition Products: Carbon oxides (CO, CO₂), methane, traces of aldehydes in fire or extreme heat
Incompatible Materials: Peroxides, nitrates, halogens
Routes of Exposure: Skin, eye contact, inhalation, accidental ingestion
Acute Toxicity: LD50 (oral, rat) estimated at 3089 mg/kg; vapor causes nose and throat irritation
Chronic Effects: Frequent or prolonged exposure can dry or crack skin, possible liver or kidney stress after long-term overuse or abuse
Symptoms: Redness, pain, headache, dizziness, drowsiness in closed-space exposure, temporary memory issues in severe overexposure
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, OSHA
Reproductive & Genetic Effects: No clear evidence from workplace exposure, studies ongoing
Other Health Data: No known bioaccumulation in mammals, quickly metabolized and eliminated
Aquatic Toxicity: Moderately toxic to aquatic organisms at high concentrations (LC50 fish: ~1000 mg/L), breakdown products can increase chemical oxygen demand in waterways
Persistence and Degradability: Biodegradable under standard environmental conditions; sunlight, water, bacteria reduce half-life to days or weeks
Bioaccumulative Potential: Low, rapid breakdown and low fat solubility
Mobility in Soil: Moves readily through soil, may reach groundwater if large spills soak in
Other Adverse Effects: High concentrations can lower dissolved oxygen in water, affecting aquatic life
Waste Methods: Incinerate in approved, properly equipped facility or dispose at licensed chemical landfill site, separate solvent waste streams to avoid mixing with incompatible chemicals
Container Handling: Drain all residues, triple rinse, puncture and flatten before disposal as hazardous waste
Regulatory Considerations: Follow local and federal hazardous waste requirements, check for solvent-specific listings in environmental codes
Avoid Releases: Never discharge into sewer, storm water, open land
Recycling: Collect unspent solvent for recovery or solvent reclamation wherever practical
