Chemical Formula: C7H14O
Purity: Typically high for industrial applications
Ingredient: 2-Heptanone, no significant impurities noted in standard grades
Inhalation: Move person to fresh air, support breathing if symptoms like coughing or shortness of breath appear
Skin Contact: Wash affected area thoroughly with soap and water
Eye Contact: Rinse eyes gently with water for at least 15 minutes, remove contact lenses if present
Ingestion: Seek medical attention, rinse mouth with water if conscious, do not induce vomiting unless directed by healthcare professional
Suitable Extinguishing Methods: Carbon dioxide, foam, dry chemical powder
Special Hazards: Vapors heavier than air, can travel to ignition sources, combustion generates toxic gases including carbon monoxide
Advice For Firefighters: Wear self-contained breathing apparatus, use water spray to cool exposed containers, avoid inhalation of smoke or fumes
Personal Precautions: Evacuate area of unnecessary personnel, ventilate area, avoid breathing vapor
Environmental Precautions: Prevent spill from entering drains or waterways, contain spill with sand or earth
Methods For Cleanup: Use non-sparking tools to collect liquid, absorb with inert material, dispose of collected material according to legal requirements
Handling: Use only in areas with adequate ventilation, keep away from heat sources and flames, avoid contact with skin and eyes
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place, keep away from incompatible materials such as oxidizing agents
Occupational Limits: 50 ppm (ACGIH TWA)
Engineering Controls: Local exhaust ventilation to limit vapor buildup
