Inhalation: Move person to fresh air, keep comfortable for breathing, provide oxygen if breathing is difficult, seek medical advice if symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water, wash with soap and water, seek medical attention if irritation occurs
Eye Contact: Rinse cautiously with plenty of water for at least 15 minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical attention if irritation persists
Ingestion: Do not induce vomiting, rinse mouth, give water to drink if person is conscious, seek immediate medical assistance
Most Important Symptoms: Headache, dizziness, nausea, skin and eye irritation, drowsiness
Notes to Physician: Treat symptomatically, monitor respiratory and cardiovascular function, no specific antidote known
Suitable Extinguishing Media: Alcohol resistant foam, dry chemical powder, carbon dioxide, water spray (do not use water jet)
Special Hazards: Vapors may form explosive mixtures with air, hazardous decomposition products include carbon oxides, fire may produce irritating or toxic fumes
Advice for Firefighters: Wear full protective clothing and self-contained breathing apparatus, move containers from fire area if without risk, use water spray to cool containers, prevent run-off from entering drains or watercourses
Specific Methods: Contain and collect extinguishing water, use water spray to knock down vapors
Personal Precautions: Evacuate unnecessary personnel, avoid breathing vapors, avoid contact with eyes and skin, remove ignition sources, ensure adequate ventilation, use personal protective equipment
Environmental Precautions: Prevent further leakage, spillage, or runoff, do not allow material to enter drains or surface water
Methods for Containment and Cleanup: Contain spill with inert absorbent material like sand or earth, transfer to labeled container for disposal, ventilate area, wash spill area after removal
Reference to Other Sections: See sections on exposure controls and personal protection, and disposal considerations for more guidance
Precautions for Safe Handling: Avoid breathing vapors, use in well-ventilated area, keep away from heat and open flame, use grounded and explosion-proof equipment, avoid contact with eyes, skin, and clothing, wash hands after handling, keep container closed when not in use
Storage Requirements: Store in a cool, well-ventilated area away from direct sunlight, sources of ignition, acids, and oxidizers, keep in original container or approved chemical container, store away from food, feed, and incompatible materials
Specific End Uses: Follow label and technical guidance for use as solvent or ingredient in formulated products
Occupational Exposure Limits: No specific established limits for N-Hexyl Acetate; recommend controlling exposure to as low as reasonably practical based on similar esters’ TLV values
Engineering Controls: Use local exhaust ventilation, general ventilation, explosion-proof equipment, and process enclosures to minimize vapor exposure
Personal Protective Equipment: Protective gloves of nitrile or neoprene, chemical splash safety goggles, face shield as needed, appropriate protective clothing, use an approved respirator in poorly ventilated areas or where vapor concentration is high
Hygiene Measures: Avoid eating, drinking, and smoking during use, wash hands thoroughly after handling, launder contaminated clothing before reuse

Skin Corrosion/Irritation: May cause mild to moderate skin irritation on prolonged or repeated exposure
Serious Eye Damage/Irritation: Causes irritation with redness, tearing, and pain
Respiratory or Skin Sensitization: Not classified as a sensitizer based on available information, but repeated skin exposure increases risk of irritation
STOT-SE (Single Exposure): Can cause drowsiness or dizziness, possible headache and nausea at high vapor concentrations
