Safety and Handling

Precautions

• Protective Gear:
  • Use gloves, goggles, and a lab coat to avoid skin and eye exposure.
  • Employ a respirator or dust mask when working in areas with potential dust formation.
• Storage:
  • Store in a cool, dry place, away from direct sunlight and moisture.
  • Keep the container tightly sealed and store separately from incompatible substances, such as strong oxidizing agents.
• Handling:
  • Work in a well-ventilated environment, preferably under a fume hood. Avoid ingestion or inhalation.

First Aid Measures

• Inhalation: Move the person to fresh air and seek medical attention if symptoms persist.
• Skin Contact: Wash with soap and water. Remove contaminated clothing and rinse thoroughly.
• Eye Contact: Rinse immediately with water for at least 15 minutes. Seek medical attention if irritation persists.
• Ingestion: Do not induce vomiting. Rinse the mouth with water and seek immediate medical attention.

Environmental Precautions
