Characteristics and notes
General Precautions:
- Avoid contact with skin and eyes: Tellurium powder can cause irritation.
- Do not breathe dust: Inhaling tellurium dust can cause irritation and congestion of the respiratory tract.
- Wash thoroughly after handling: Remove any powder from skin and clothing.
- Do not eat, drink, or smoke while handling: Avoid contamination of food or drink.
- Keep away from food, drink, and animal feeding stuffs: Prevent accidental ingestion.
- Keep working clothes separately: Prevent contamination of personal clothing.
- Ensure eyewash stations and safety showers are close to the workstation location
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.
