Explosion Data: Avoid accumulation of vapor; flash point typically above 120°C
Personal Precautions: Evacuate area, ventilate, avoid breathing vapors, wear gloves and protective goggles
Containment: Stop leak if safe, prevent entry into drains or watercourses
Spill Cleanup: Soak up small spills with inert absorbent, shovel into suitable container, dispose in compliance with local regulations
Decontamination: Wash spill area with water and mild detergent to remove residues
Environmental Precautions: Notify authorities if large quantities enter water or soil
Handling: Use in a well-ventilated space, minimize inhalation and skin contact, avoid spraying or atomizing, wear recommended personal protective equipment
Storage Conditions: Store in tightly closed containers, out of direct sunlight, in a dry, cool, well-ventilated area
Incompatibilities: Avoid contact with strong oxidizing agents and acids
Packaging Materials: Stainless steel, polyethylene, or glass containers preferred
Specific Use Guidance: Limit access to trained personnel, label containers clearly
Exposure Limits: No specific occupational exposure limits established; general ventilation and controls required
Engineering Controls: Use local exhaust ventilation to minimize vapor exposure
Personal Protection: Wear safety goggles, chemical-resistant gloves (nitrile or neoprene), and protective clothing
Respiratory Protection: Use a suitable organic vapor respirator if airborne concentrations increase significantly
Hygiene Measures: Wash hands thoroughly after handling, avoid eating or drinking in work area, remove contaminated clothing promptly
Appearance: Clear, colorless to pale yellow liquid

Acute Toxicity: Oral LD50 (rat): 1,400-2,000 mg/kg
Skin Corrosion/Irritation: May cause mild skin irritation after repeated or prolonged exposure
Serious Eye Damage/Irritation: Causes moderate, temporary eye irritation
Sensitization: Not classified as skin sensitizer under current data
Chronic Effects: No reliable evidence linking to systemic toxicity from long-term exposures
Carcinogenicity: Not listed by IARC, NTP, or OSHA; low risk based on present data
Other Information: Headaches, nausea, and dizziness possible after vapor inhalation in confined spaces
Aquatic Toxicity: Low to moderate toxicity for aquatic life, with fish and invertebrate LC50 values generally above 10 mg/L
Persistence/Degradability: Biodegradable in soil and water, persistence not expected in well-managed systems
Bioaccumulation Potential: Moderate based on n-octanol/water partition coefficient, but significant accumulation considered unlikely in real-world scenarios
Mobility: Slight mobility in soils; spills can reach watercourses if large volumes escape containment
Other Adverse Effects: High concentrations might cause oxygen depletion in confined water bodies
