Safety and Handling
Safety Precautions
While PEG 4000 is considered safe, proper precautions must be observed during handling.
- Personal Protective Equipment (PPE): Wear gloves and goggles to prevent direct contact.
- Avoid Inhalation: Use in a well-ventilated environment to avoid inhaling dust.
- Minimize Contact: Avoid prolonged skin or eye contact.
First Aid Measures
- Skin Contact: Wash thoroughly with soap and water. Seek medical advice if irritation develops.
- Eye Contact: Flush eyes with water for at least 15 minutes. Consult a healthcare professional if symptoms persist.
- Inhalation: Move to fresh air and seek medical attention if symptoms arise.
- Ingestion: Rinse mouth and drink water. Contact a physician if adverse effects occur.
Storage Guidelines
- Store in a cool, dry place, away from direct sunlight and moisture.
- Keep containers tightly closed to prevent contamination.
- Avoid contact with strong oxidizing agents.
Environmental Considerations
PEG 4000 is biodegradable and environmentally friendly when used appropriately. Prevent large-scale release into waterways or soil.
