Safety and Handling

Hazards

Potassium Nitrate is an oxidizer and can enhance combustion of flammable materials. Direct contact may cause irritation to skin, eyes, or respiratory tract.

Precautions

• Personal Protective Equipment (PPE):
  • Wear gloves, safety goggles, and protective clothing during handling.
• Storage:
  • Store in a cool, dry place away from heat, moisture, and incompatible substances like organic materials or reducing agents.
• Handling:
  • Avoid inhalation of dust and direct contact with skin or eyes. Ensure adequate ventilation.

First Aid Measures

• Skin Contact: Rinse skin with soap and water. Seek medical advice if irritation persists.
• Eye Contact: Flush eyes thoroughly with water for at least 15 minutes. Consult a doctor if irritation continues.
• Inhalation: Move to fresh air and seek medical attention if breathing difficulties occur.
• Ingestion: Rinse mouth and drink water. Contact a healthcare provider immediately.

Environmental Considerations

Potassium Nitrate should not be released into water bodies. Dispose of waste responsibly to avoid environmental contamination.
