CAS Number: 2437-29-8
Impurities: Usually minimal, specific residues dependent on manufacturing method
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, seek medical attention
Skin Contact: Wash thoroughly with soap and plenty of water, remove contaminated clothing, seek medical advice if irritation persists
Inhalation: Move individual to fresh air, maintain open airway, seek medical attention for any symptoms
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention
Suitable Extinguishing Methods: Use water spray, CO2, dry powder, or foam; avoid breathing dust or fumes
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, and toxic fumes may form
Protective Equipment: Firefighters should use self-contained breathing apparatus along with standard protective gear
Personal Precautions: Avoid direct contact, use protective gloves, mask, eye protection, ventilate area
Clean-up Methods: Collect spilled material carefully, avoid creating dust, place in appropriate waste container
Environmental Precautions: Avoid discharge to drains or water bodies, contain spillage
Safe Handling: Use in well-ventilated areas, avoid inhalation and excessive skin contact, always wear suitable protective equipment
Storage: Store in tightly closed containers in dry, cool, well-ventilated locations away from incompatible materials, especially strong oxidizers and acids
Engineering Controls: Local exhaust ventilation recommended to limit airborne concentrations
Personal Protection: Nitrile gloves, chemical safety goggles, lab coats, suitable dust mask or respirator
