Tellurium Powder
SKU: RXSOL-98-9817-025
Category: Metal Treatment-68
Tellurium powder is a dark gray-to-brown, amorphous, brittle powder, a metalloid element with the symbol Te, used in various applications including solar cells, thermoelectric production, metallurgy, and rubber applications.
Personal Protective Equipment (PPE):
- Wear protective gloves: Choose gloves that are impermeable to tellurium.
- Wear protective clothing: Wear clothing that covers exposed skin.
- Wear eye protection: Use goggles or a face shield to protect eyes from dust.
- Wear a dust mask: Use a dust mask (like an N95) to prevent inhalation of dust.
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
