Safety and Handling
- Hazards:
- Potassium tetraoxalate is a strong acid and can cause irritation to the skin, eyes, and mucous membranes.
- It is toxic if ingested in significant quantities due to the oxalate ions, which can form insoluble calcium oxalate crystals in the kidneys.
- Precautions:
- Always wear appropriate personal protective equipment (PPE) such as gloves, goggles, and protective clothing when handling potassium tetraoxalate.
- Ensure adequate ventilation when working with the compound to avoid inhalation of dust.
- Store in a cool, dry place, away from incompatible substances such as acids and strong bases.
- First Aid:
- Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes. Seek medical attention if irritation persists.
- Skin Contact: Wash exposed skin areas with soap and water. If irritation occurs, seek medical help.
- Inhalation: Move to fresh air immediately. If breathing difficulties persist, consult a doctor.
- Ingestion: If swallowed, rinse mouth with water. Do not induce vomiting. Seek immediate medical attention.
