Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Avoid inhalation and skin contact.
Use method most appropriate to fight surrounding fire.
When heated to decomposition, it emits toxic fumes of tellurium and sodium monoxide.
Fire may produce irritating, corrosive and/or toxic gases.
OSHA: PEL (8 h TWA): 0.1 mg/m3.
Tellurium inhibits sweating. Sodium tellurite induced significant reduced body temperature in experimental animals. Headache and drowsiness have been seen after human exposure to tellurium compounds. Malaise, weakness, lassitude and dizziness have also occurred. No reproductive data were found for sodium tellurite. Tellurium compounds have been teratogenic in experimental animals.
Anorexia, nausea, vomiting, garlicky odor, metallic taste, and constipation have occurred from exposure to tellurium compounds. The garlic odor may occur from other routes of exposure besides ingestion.
Irritation, pulmonary edema, respiratory depression, and death have been noted in experimental animals exposed to various tellurium compounds by inhalation. Similar effects have not been seen in isolated human exposures.
Avoid any skin contact. See Inhalation.
Dry mouth and throat have also been seen after exposure to this compound. Hair loss occurred in one case of acute intoxication from tellurium-contaminated meat.
Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Remove material from skin immediately. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
