Ingestion: Rinse mouth, do not induce vomiting. Drink water to dilute. Seek immediate medical attention, especially if large quantities are swallowed.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, or water spray can be used.
Specific Hazards: Combustible liquid, gives off irritating or toxic fumes (carbon oxides) in fire.
Protective Equipment for Firefighters: Full chemical protective clothing and self-contained breathing apparatus.
Advice for Firefighters: Cool containers with water spray to prevent rupture due to heat. Avoid breathing vapors, keep people away from fire zone.
Personal Precautions: Evacuate area, avoid contact with spilled substance, use personal protective equipment including eye and skin protection.
Environmental Precautions: Prevent entry into drains, waterways, or soil. Report significant spills in accordance with government regulations.
Methods for Containment: Absorb spill with inert material (sand, earth, or suitable absorbent), then collect in containers for proper disposal. Wash area after removal.
Safe Handling: Avoid contact with eyes and skin. Use only in well-ventilated areas. Protection from inhalation recommended.
Storage Requirements: Store in tightly closed original container in a cool, dry, and well-ventilated place, away from incompatible substances such as strong acids and oxidizers.
Special Instructions: Ground/bond container and receiving equipment. Keep out of reach of children and unauthorized personnel.
Exposure Limits: No established occupational exposure limits; recommend minimizing exposure as with most fragrance chemicals.
Engineering Controls: Use local exhaust or ventilation to minimize vapor accumulation.
Eye/Face Protection: Safety goggles or shield recommended.
Skin Protection: Impermeable gloves (nitrile, neoprene) and protective clothing.
