Mixture: Not a mixture. Single-constituent organic chemical
Inhalation: Move affected person to fresh air. Inhaling significant amounts of dust rarely causes symptoms and usually requires no medical attention. Seek medical advice if symptoms like coughing persist.
Skin Contact: Remove contaminated clothing. Wash skin with soap and water. Seek medical advice if irritation develops.
Eye Contact: Rinse with plenty of water for at least several minutes, lifting eyelids. Remove contact lenses if easy. Seek medical attention if discomfort does not abate.
Ingestion: Rinse mouth with water. Do not induce vomiting unless recommended by medical personnel. Unlikely to cause significant harm at low levels. Large doses may cause gastrointestinal distress. Seek medical attention if feeling unwell.
Acute/Delayed Symptoms: Mild irritation possible but not usual. No delayed severe effects known.
Notes to Physician: Treat symptomatically. No antidote necessary.
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct stream of water may spread burning liquid
Hazards from Combustion: Combustion produces carbon oxides such as carbon monoxide and carbon dioxide. No unusual fire or explosion hazards.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full firefighting gear
Special Precautions: Containers exposed to heat may burst. Evacuate area and fight fire from a safe distance
Advice: Keep runoff out of local waterways if possible. Cool adjacent containers to prevent thermal stress.
Personal Precautions: Avoid dust formation. Ensure adequate ventilation. Avoid contact with eyes and skin.
Protective Equipment: Wear gloves, protective goggles, lab coat. Use a dust mask if significant dust is generated.
Environmental Precautions: Prevent entry to sewers and surface waters. Contain spill with inert absorbent like sand.
Cleanup Methods: Sweep or scoop up and transfer to container for recovery or disposal. Wash area with water. Dispose of as non-hazardous chemical waste.
Other Information: Small spills typically do not present acute risk but should still be handled with care.
Handling: Use in well-ventilated area. Minimize dust and direct contact. Avoid hand-to-mouth actions in the laboratory or production floor. Keep containers tightly closed after use.
Storage Conditions: Store in a cool, dry, and well-ventilated place. Protect from light and moisture. Keep away from incompatible materials such as strong oxidizing agents and acids.
Incompatibilities: Strong oxidizers, strong acids, strong bases
Other Storage Advice: Use original container or a compatible, tightly sealed chemical storage bottle. Avoid excessive heat and humidity.
Storage Class: General chemicals not requiring special security or refrigeration.
Occupational Exposure Limits: No specific limits established by OSHA, ACGIH, or European authorities
