4. First-Aid Measures

4.1 First-aid measures

Eye Contact: Rinse thoroughly with plenty of water for several minutes, occasionally lifting the upper and

lower eyelids. Get medical attention if symptom persists.

Skin Contact: Wash with soap and water while removing contaminated clothing and shoes. Wash clothing

before reuse. Consult a physician if symptom persists.

Inhalation: Remove victim to fresh air and keep at rest in a position comfortable for breathing. If

breathing is difficult, give oxygen. If not breathing, give artificial respiration. Consult a physician.

Ingestion: Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or

water. Wash mouth out with water. Consult a physician if irritation or symptoms occur.

4.2 Acute or chronic effects:

Acute effects: Irritating to eyes, mucous membrane, skin and respiratory tract. May cause headache,

nausea and vomiting.

Chronic effects: No relevant research data.

4.3 Note to physician: Treat symptomatically.

5. Fire-Fighting Measures

Suitable Extinguishing Media: Extinguish with foam, water spray and sand. Do not use dry chemical or

carbon dioxide.

Special Hazards Arising from the Chemical: Thermal decomposition or combustion may release

irritating or high toxic gases and fumes.

Special Protective Actions for Fire-fighters: Fire-fighters should wear self-contained breathing

apparatus in pressure-demand and full fire-fighting turn-out gear. Extinguishing the fire from upwind and keep a

safe distance.6. Accidental Release Measures

Personal Precautions, Protective Equipment and Emergency Procedures: Isolate spill or leak area in all

directions. Keep unauthorized personnel away. Wear anti-dust masks, protective clothing. Ensure adequate

ventilation. Do not directly contact with the leakage. Stay upwind.

Precautions to Protect the Environment: Avoid let into waterways, sewers, basements or confined areas.

Methods and Materials for Containment and Cleaning Up: Provide ventilation. Avoid raising dust. Cut off

leakage if possible. Vacuum or sweep up leakage and put into a clean sealed container for further recycle or

disposal. If product is not contaminated, scoop into clean containers for reuse.

7. Handling and Storage

Precautions for Safe Handling: Avoid any source of contact. Avoid inhalation of dust. Avoid formation of

dust. Provide appropriate exhaust ventilation at places where dust is formed. Do not ingest. Keep container

tightly closed when not in use. Wash hands with soap and water before eating, drinking and smoking.

Conditions for Safe Storage: Keep container tightly closed in a dry, cool, well-ventilated place without

direct sunlight. Keep away from fire and heat. Keep away from oxidizes and acid. Storage area should be

equipped with right material and equipment to collect leakage. Avoid contaminated water, food or feeds.

8. Exposure Controls/Personal Protection

Control parameters: Not established.

Appropriate Engineering Controls: Provide enough natural or local ventilation. Facilities storing or

utilizing this material should be equipped with an eyewash facility and a safety shower.

Individual protective measure:

Respiration Protection: If dust exceeds recommended exposure limits, wear a self-absorption filter gas

mask (half mask). Wear an air respirator when emergency.

Hands Protection: Wear general protective gloves.

Skin Protection: Wear anti-static working clothing.

Eye Protection: Wear chemical safety goggles.

Hygiene Measures: Do not eat, drink or smoke at working place. Wash hands thoroughly and immediately

after handling the product.
