Inhalation: Move exposed person to fresh air, monitor for symptoms such as headache or dizziness, and seek medical advice if ill effects persist
Skin Contact: Wash skin immediately using soap and water; remove contaminated clothing and launder before reuse; seek medical support if irritation continues
Eye Contact: Rinse eyes cautiously with water for at least fifteen minutes, holding eyelids open, and get medical care if discomfort lingers
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention if large quantities have been swallowed or if symptoms appear
Note for Healthcare Providers: Treat symptoms, maintain airway and circulation, support vital functions as required
Extinguishing Media: Use dry chemical powder, CO2, foam, or water fog; avoid jet streams of water that could spread the fire
Specific Hazards: Heat can yield irritating or toxic vapors such as carbon monoxide, carbon dioxide, and other organic compounds
Protective Equipment: Firefighters should don full protective gear with self-contained breathing apparatus for enclosed or high vapor situations
Firefighting Instructions: Approach fire from upwind to avoid hazardous vapors and remain alert to possible accumulation of flammable vapors in low-lying areas
Personal Precautions: Isolate spill area, ventilate the area, and use protective equipment to avoid inhalation and skin contact
Environmental Precautions: Prevent release to sewers or waterways; dike spillages with sand, earth, or inert absorbent to restrict spread
Containment and Cleanup: Absorb using non-combustible material; collect residues in labeled containers for disposal; use spark-proof tools
Disposal: Place cleanup materials in suitable disposal containers and move to approved waste handling sites
Handling: Use only in well-ventilated areas; enforce hygiene measures such as washing after handling; avoid contact with skin, eyes, and clothing
Storage: Keep product in tightly closed containers, store in cool, dry, and well-ventilated locations away from sources of ignition and incompatible materials
Incompatibilities: Store away from acids, strong oxidizers, and reactive substances
Packaging: Prefer metal, glass, or HDPE drums/cans that resist solvent permeation and minimize environmental exposure
Occupational Exposure Limits: ACGIH TLV – TWA: 100 ppm (606 mg/m³); OSHA PEL: 100 ppm (600 mg/m³)
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to maintain air concentrations below regulatory limits
Personal Protection: Wear safety goggles, nitrile or neoprene gloves, and protective clothing; if ventilatory controls are insufficient, use approved respirators
Hygiene Measures: Change out of contaminated clothing immediately and wash before reuse to avoid skin irritation or secondary exposures

Evaporation Rate: Slower than butyl acetate
Chemical Stability: Stable under normal ambient and anticipated storage and handling conditions
Reactivity: May react with strong oxidizing agents, acids, and bases at elevated temperatures to produce hazardous products
Conditions to Avoid: Excessive heat, open flames, and all sources of ignition
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, and other volatile organic compounds in case of thermal breakdown or fire
Acute Toxicity: Oral LD50 (rat): >5,400 mg/kg; dermal LD50 (rabbit): >9,500 mg/kg; inhalation LC50 not established
Skin Corrosion/Irritation: Mild irritation possible on prolonged exposure
Eye Damage/Irritation: Direct contact can cause mild, reversible irritation
Respiratory Effects: Excessive vapor exposure may cause nose, throat or lung irritation, headache, or drowsiness
Chronic Effects: Limited evidence of chronic toxic effects in occupational settings, no evidence of carcinogenicity, mutagenicity, or reproductive toxicity in standard tests
Sensitization: Does not appear to cause allergic sensitization based on available data
Ecotoxicity: Practically non-toxic to aquatic organisms; LC50 (fish, 96 hrs): >10,000 mg/L
Persistence and Degradability: Readily biodegradable under aerobic conditions, over 60% degraded in 28 days in OECD test
