Section 3 - Hazards Identification
Appearance: orange to brown powder.
Warning! Harmful if swallowed, inhaled, or
absorbed through the skin. Causes eye, skin, and respiratory tract
irritation. Possible risk of harm to the unborn child. May cause
nervous system effects. The toxicological properties of this material
have not been fully investigated.
Target Organs: Blood, central nervous system,
Potential Health Effects
Causes eye irritation.
Causes skin irritation.
Harmful if swallowed. Ingestion of tellurium and its compounds has
produced symptoms such as "garlic-like" odor of the breath and sweat,
metallic taste, sleepiness, anorexia, cyanosis, restlessness, tremor,
diminished reflexes, paralysis, convulsions, liver damage, and nausea
Causes respiratory tract irritation.
Possible risk of harm to the unborn child. Prolonged or repeated
exposure affects the nervous system.
Section 4 - First Aid Measures
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid.
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Flash Point: Not applicable.
Autoignition Temperature: Not applicable.

(estimated) Health: 2; Flammability: 1; Instability: 0
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Section 7 - Handling and Storage
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid ingestion
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Section 8 - Exposure Controls, Personal Protection
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

Carbon monoxide, carbon dioxide, tellurium fumes.
Hazardous Polymerization: Has not been reported
Section 11 - Toxicological Information
Not listed by ACGIH, IARC, NTP, or CA Prop 65.
No reports of serious illness in workers exposed to Te &
its compounds in industry were identified. Complaints &
findings, including anorexia, nausea, drowsiness, metallic
taste, & garlic-like odor to breath & sweat, are major
negative effects reported.
Studies have found that diphenyl ditelluride can be
teratogenic to rat fetuses and toxic for dams. The late
fetal stages of rat prenatal development appeared uniquely
sensitive to organic tellurium exposure.
No information found
No information found
Diphenyl ditelluride is extremely neurotoxic and even
compounds that release the Te atom slowly may represent a
neurotoxic time bomb for mammals.
Section 12 - Ecological Information
No information available.
Section 13 - Disposal Considerations
Chemical waste generators must determine whether a discarded chemical is classified
as a hazardous waste.
