Chemical Name: Isobutyl Acetate
Concentration: 99% or greater by weight
CAS Number: 110-19-0
Impurities/Additives: May contain trace stabilizers, impurities below 1% with no significant hazard classification
Other Ingredients: No hazardous non-disclosed components above regulatory thresholds
Inhalation: Remove to fresh air without delay. Get medical attention for ongoing symptoms such as breathing difficulty, headache, or dizziness. Place victim in a position comfortable for breathing. Administer oxygen by trained personnel if breathing is difficult.
Skin Contact: Remove contaminated clothing immediately. Wash skin thoroughly with plenty of soap and water. Seek medical attention if irritation develops or persists.
Eye Contact: Rinse eyes with lukewarm, gently flowing water for at least 15 minutes while holding eyelids open. Remove contact lenses if present and easy to do. Contact medical personnel if pain, blinking, or redness continue.
Ingestion: Rinse mouth. Do not induce vomiting. Never give anything by mouth to an unconscious or convulsing person. Seek medical aid if feeling unwell or if large quantities are ingested.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, or water spray or fog. Avoid straight water streams that may spread the fire.
Hazards from Combustion: Forms toxic and irritating gases when burned including carbon monoxide and carbon dioxide.
Special Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing.
Further Advice: Evacuate surrounding area. Cool fire-exposed containers with water spray to prevent rupture due to heat. Prevent water runoff from entering drains or watercourses.
Personal Precautions: Evacuate personnel from area if vapors are present. Eliminate all ignition sources. Provide adequate ventilation. Wear respiratory protection if vapor concentration is elevated.
Environmental Precautions: Prevent entry into sewers, waterways, or soil. Alert authorities if spillage contaminates water environment.
Containment: Stop leak if safe to do so. Dike with non-combustible material to contain liquid.
Cleanup Methods: Absorb with earth, sand, or other inert absorbent. Place in appropriate labeled containers for disposal. Wash spill site after pickup with plenty of water.
Safe Handling: Avoid inhalation and contact with skin or eyes. Use in well-ventilated areas. Ground and bond containers during liquid transfer. Only use spark-proof tools and equipment. Do not eat, drink, or smoke in handling areas.
Storage Recommendations: Store tightly closed in a cool, dry, well-ventilated place away from sources of ignition or heat. Segregate from oxidizers, acids, and strong alkalis. Keep container tightly sealed when not in use. Store at temperatures below 30°C (86°F) away from direct sunlight.
Occupational Exposure Limits: OSHA PEL: 150 ppm (710 mg/m³) (TWA); ACGIH TLV: 150 ppm
Engineering Controls: Local exhaust ventilation recommended. Personal enclosure or process enclosure where applicable.
Respiratory Protection: Approved air-purifying respirator for organic vapors if airborne exposure limit is exceeded.
Hand Protection: Impermeable gloves, such as nitrile or neoprene.
Eye Protection: Chemical safety goggles or face shield.
Skin Protection: Chemical-resistant clothing as needed.
Hygiene: Wash hands and exposed skin after use. Remove and clean contaminated clothing before reuse.
