Impurities: Trace esters, alcohols, or acids, rarely present above 1%
Other Ingredients: None indicated or classified as hazardous based on typical specifications
Inhalation: Remove person to fresh air, keep individual at rest. Seek medical attention if symptoms like dizziness or nausea continue.
Skin Contact: Wash exposed skin generously with soap and water. Remove contaminated clothing.
Eye Contact: Rinse cautiously with water for at least fifteen minutes, spread eyelids wide. Remove contact lenses if easy to do. Get medical help if discomfort lingers.
Ingestion: Rinse mouth, do not induce vomiting. Small sips of water permitted. Get medical advice quickly if feeling unwell or experiencing persistent effects.
Symptoms: Headache, nausea, respiratory irritation, drowsiness possible after heavy exposure.
Flammability: Highly flammable liquid, vapor forms explosive mixtures with air
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, water fog for cooling
Special Hazards: Produces hazardous vapors under fire conditions, including carbon oxides
Advice for Firefighters: Wear full protective gear and self-contained breathing apparatus
Explosion Risk: Sealed containers may rupture when exposed to fire
Firefighting Procedures: Avoid direct water stream to prevent fire spread, use spray to cool surfaces, evacuate area as needed
Personal Precautions: Avoid breathing fumes, ventilate area, keep ignition sources away, evacuate unsuitable personnel
Spill Response: Use non-sparking tools, collect liquid with absorbent (sand, earth, vermiculite), put in chemical waste container
Cleanup Methods: Do not let product enter drains, sewers, or soil. Wash residual spills away with copious amounts of water, but avoid runoff
Personal Protection: Gloves, goggles, chemical-resistant coveralls, respiratory protection for vapors
Handling: Use in well-ventilated areas, ground containers and transfer equipment, avoid direct contact with liquid or vapors
Hygiene: Wash hands after use, remove and wash contaminated clothing before reuse
Storage Conditions: Store tightly closed in a cool, dry, well-ventilated area, away from heat, sparks, open flame. Use flame-proof equipment
Incompatible Materials: Acids, oxidizing agents, bases, reducing agents, strong alkalis
Transfer Precautions: Use non-sparking tools and static-resistant containers
Occupational Exposure Limits: OSHA PEL: 150 ppm (710 mg/m³), ACGIH TLV: 50 ppm, STEL: 150 ppm
Engineering Controls: Local exhaust ventilation recommended, ensure eyewash stations and safety showers nearby
