Emergency Overview :
Tellurium in melted form are toxic by inhalation and if swallowed. Copper powder is harmful by inhalation and assessed as very toxic to fish and other aquatic organisms and may cause long-term adverse effects in the aquatic environment.
Potential Health Effects
Swallowing this product is suspected to cause toxic effects.
Inhaling this product is suspected to cause toxic effects.
4. FIRST AID MEASURES
Fresh air and rest in a warm place. Possibly assisted the patient with respiration. Seek medical advice, even if there are no or only slight symptoms.
Give a couple of glasses of water to drink if the person is fully conscious. Contact a doctor if a larger amount has been swallowed.
5. FIRE FIGHTING MEASURES
Elementary tellurium burns slowly in the presence of air, giving a green-blue flame. Dust may form explosive mixtures with air.
Not Applicable
Not Applicable
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Wear self contained breathing apparatus for firefighting if necessary.
6. ACCIDENTAL RELEASE MEASURES
Sweep up and shovel. Keep in suitable, closed containers for disposal.
Personal Precaution
Wear appropriate respirator when ventilation is inadequate. Put on appropriate personal protective equipment. Avoid dust formation. Avoid breathing vapors, mist or gas.
Environmental Precaution
Do not let product enter drains.
7. HANDLING AND STORAGE
Provide appropriate exhaust ventilation at places where dust is formed. Normal measures for preventive fire protection.
Storage Precaution
Store in cool place. Keep container tightly closed in a dry, well-ventilated place and on waterproof floor. In accordance with preventing of pollution, any spillage should not be discharge into the environment. Symbol and emergency response equipments should be provided in accordance with applicable regulations.
Work/Hygienic Practices
Store the materials away from food, feedstuffs and explosive substances. Always practice good personal hygiene.

12. ECOLOGICAL INFORMATION
Even small amounts of copper ions are very toxic to aquatic organisms. The potential to form ions from solid metal depends on the particle size and factors in the surrounding environment, such as pH, redox-potential and the amount of organic material. An acidic pH is favouring the solubility of copper compounds. Copper in form of powder, is considered as very toxic to fish and other aquatic organisms.
