Safety and Handling

Hazards

Potassium Nitrite is a strong oxidizer and may pose risks of combustion when in contact with organic materials. It is also toxic if ingested, inhaled, or absorbed through the skin.

Precautions

• Personal Protective Equipment (PPE):
  • Use gloves, goggles, and lab coats during handling.
• Storage:
  • Keep in a cool, dry, and well-ventilated area. Avoid exposure to heat, sunlight, or incompatible substances.
• Handling:
  • Avoid contact with skin or eyes, and prevent inhalation of dust. Ensure proper ventilation in workspaces.

First Aid Measures

• Skin Contact: Wash thoroughly with soap and water. Seek medical attention if irritation occurs.
• Eye Contact: Rinse eyes with plenty of water for at least 15 minutes. Consult a doctor if irritation persists.
• Inhalation: Move to fresh air. Seek immediate medical attention if respiratory distress occurs.
• Ingestion: Do not induce vomiting. Rinse the mouth and contact a healthcare provider immediately.

Environmental Considerations

Potassium Nitrite should not be discharged into water sources. Dispose of it responsibly according to local environmental regulations.
