Safety and Handling

Precautions

• Personal Protective Equipment (PPE):
  • Wear gloves, goggles, and lab coats to avoid skin and eye contact.
  • Ensure good ventilation or use a fume hood to prevent inhalation of vapors.
• Storage:
  • Store in a cool, dry, and well-ventilated area away from sources of ignition and incompatible substances like strong oxidizers.
  • Keep the container tightly sealed to prevent contamination and degradation.

First Aid Measures

• Inhalation: Move the affected person to fresh air immediately. If breathing difficulties persist, seek medical attention.
• Skin Contact: Wash the affected area with soap and water. Remove contaminated clothing.
• Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes. Seek medical attention if irritation continues.
• Ingestion: Rinse the mouth with water and seek medical help. Do not induce vomiting unless advised by a healthcare provider.

Environmental Precautions

• Prevent the compound from entering drains, water systems, or soil.
• In case of spills, absorb and contain using appropriate materials (e.g., sand or activated carbon). Dispose of the material in accordance with local hazardous waste regulations.

Disposal
