Safety Guidelines:

1. Personal Protective Equipment (PPE):
   • Skin Protection: Wear gloves and appropriate protective clothing to prevent skin contact, as prolonged exposure may cause irritation.
   • Eye Protection: Always use safety goggles or face shields when handling Sodium Tungstate Solution to avoid splashes into the eyes.
   • Respiratory Protection: If working with the solution in a poorly ventilated area or in aerosolized form, wear a respirator to avoid inhalation of any mist or vapor.
2. Storage:
   • Store Sodium Tungstate Solution in a cool, dry, and well-ventilated area away from incompatible materials such as strong acids or oxidizers.
   • Ensure that the containers are tightly sealed to avoid moisture absorption and contamination, which could affect the solution’s quality and performance.
3. First Aid:
   • Inhalation: If inhaled, move the person to fresh air immediately. If respiratory symptoms persist, seek medical attention.
   • Skin Contact: In case of skin contact, wash the affected area thoroughly with soap and water. Seek medical attention if irritation occurs.
   • Eye Contact: If Sodium Tungstate Solution comes into contact with the eyes, rinse immediately with plenty of water for at least 15 minutes. Seek medical attention if irritation persists.
   • Ingestion: If ingested, rinse the mouth with water. Do not induce vomiting unless instructed by a healthcare professional. Seek immediate medical attention.
4. Disposal:
   • Dispose of Sodium Tungstate Solution according to local, state, and federal environmental regulations. It is important to avoid contaminating water sources and dispose of the solution in accordance with hazardous waste disposal guidelines.
