- Environmental Hazards: May be harmful to aquatic life. Avoid release into water bodies.
- Flammability: Zinc powder is flammable when dispersed in air. Sparks, open flames, or heat sources should be avoided.
4. First Aid Measures
- Inhalation: Move to fresh air. If breathing is difficult, seek medical attention immediately.
- Skin Contact: Wash affected area with plenty of water. Remove contaminated clothing.
- Eye Contact: Rinse eyes with water for at least 15 minutes. Seek medical help if irritation persists.
- Ingestion: Do not induce vomiting. Consult a physician immediately.
5. Fire Fighting Measures
- Extinguishing Media: Use dry chemical, carbon dioxide, or foam extinguishers. Water mist may also be used.
- Special Hazards: Fine zinc powder can form explosive mixtures with air. Avoid using water directly on burning material due to potential reaction with zinc.
6. Accidental Release Measures
- Personal Protection: Wear appropriate protective equipment including gloves, goggles, and a respirator.
- Containment: Contain the spill using absorbent materials. Avoid generating dust.
- Cleanup: Sweep up and place in sealed containers. Dispose of according to local regulations.
7. Handling and Storage
- Handling: Avoid inhalation and skin contact. Use proper ventilation and personal protective equipment.
