Safety and Handling
Hazards
Potassium Permanganate is a strong oxidizing agent and can pose serious risks if not handled properly. It is harmful to skin, eyes, and respiratory systems.
Precautions
- Personal Protective Equipment (PPE):
- Wear appropriate gloves, protective goggles, and clothing to prevent skin and eye contact.
- Use a respiratory mask if handling large amounts or working in confined spaces.
- Storage:
- Store in a cool, dry, and well-ventilated area away from combustible materials and reducing agents.
- Keep containers tightly sealed and away from incompatible substances such as acids and flammable materials.
- Handling:
- Handle with care and avoid direct contact with the skin and eyes.
- Do not ingest or inhale the product.
- Always use the chemical in a well-ventilated area or under a fume hood when necessary.
First Aid Measures
- Skin Contact: Immediately wash the affected area with plenty of water. Seek medical attention if irritation persists.
- Eye Contact: Flush the eyes with water for at least 15 minutes. Seek medical assistance immediately.
- Inhalation: Move to fresh air and provide rest. Seek medical attention if symptoms persist or worsen.
- Ingestion: Rinse the mouth with water, but do not induce vomiting. Seek immediate medical care.
