HAZARD IDENTIFICATION
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
Eyes
:
Contact with eyes may cause slight irritation.
Skin
:
Direct skin contact may result in irritation in some workers.
Ingestion
:
Swallowing this product is suspected to cause toxic effects.
Inhalation
:
Inhaling this product is suspected to cause toxic effects.
Chronic Effects
:
-
FIRST AID MEASURES
Eye Contact
:
Rinse with water.
Skin Contact
:
Immediately, take off all contaminated clothing/shoes. Carefully wash the skin for several minutes with soap and water. Contact a doctor if the complaints persist.
Inhalation
:
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.
Ingestion
:
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.
FIRE FIGHTING MEASURES
Fire and Explosion Hazards
:
Elementary tellurium burns slowly in the presence of air, giving a green-blue flame. Dust may form explosive mixtures with air.

:
Non-flammable and does not support combustion.
Flammable limit
:
Not Applicable.
Autoignition Temperature
:
Not Applicable.
Extinguishing Media
:
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Fire Fighting
:
Wear self contained breathing apparatus for firefighting if necessary.
ACCIDENTAL RELEASE MEASURES
Procedure for Clean Up
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.
HANDLING AND STORAGE
Handling Precaution
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.

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.
DISPOSAL CONSIDERATIONS
Recycle, if possible. The generation of waste should be avoided or minimized wherever possible. Dispose of surplus and non-recyclable products via a licensed waste disposal contractor. The classification of the product may meet the criteria for a hazardous waste. Care should be taken when handling emptied containers that have not been cleaned or rinsed out.
TRANSPORT INFORMATION
Transportation is carried out using sealed containers.
