| Hazard Information | Back Directory | [Chemical Properties]
Tellurium hexafluoride is a colorless gas with a repulsive odor. | [General Description]
TELLURIUM HEXAFLUORIDE is a colorless gas with a repulsive odor. TELLURIUM HEXAFLUORIDE is very toxic by inhalation and skin absorption. When heated to high temperatures, TELLURIUM HEXAFLUORIDE may emit toxic fluoride and tellurium fumes. TELLURIUM HEXAFLUORIDE is heavier than air. Under prolonged exposure to fire or intense heat the containers may violently rupture and rocket. TELLURIUM HEXAFLUORIDE reacts with water to yield toxic vapors. | [Air & Water Reactions]
TELLURIUM HEXAFLUORIDE reacts with water to yield toxic hydrogen fluoride vapors. TELLURIUM HEXAFLUORIDE emits very toxic fumes of fluoride and tellurium. Decomposes in water, acid, and alkali. [EPA, 1998]. | [Reactivity Profile]
TELLURIUM HEXAFLUORIDE is a colorless, toxic gas, when heated to decomposition TELLURIUM HEXAFLUORIDE emits very toxic fumes containing metallic tellurium and tellurium fluorides [Lewis, 3rd ed., 1993, p. 1207]. | [Health Hazard]
Capable of causing death or permanent injury. Acute -the material is highly toxic by inhalation exposure and a strong irritant to skin, eyes, the lungs, the throat, and stomach. Death can occur from filling of the lungs with fluid (pulmonary edema) or from asphyxiation due to spasm of the throat (larynx) or bronchi. Those with impaired pulmonary function, especially obstructive airway diseases are at a greater risk. | [Fire Hazard]
Container may explode in heat of fire. When heated to decomposition, TELLURIUM HEXAFLUORIDE emits very toxic fumes of fluoride and tellurium. Decomposes in water, acid, and alkali. | [Potential Exposure]
Tellurium hexafluoride is stated to be a by-product of ore refining. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
| [Shipping]
UN2195 Tellurium hexafluoride, Hazard Class: 2.3; Labels: 2.3-Poisonous gas, 8-Corrosive material, inhalation hazard zone A. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner. | [Incompatibilities]
Hydrolyzes slowly in water forming telluric acid. Emits highly toxic fumes when heated or on contact with acid or acid fumes. | [Waste Disposal]
Return refillable compressed gas cylinders to supplier. Nonrefillable cylinders should be disposed of in accordance with local, state and federal regulations. Allow remaining gas to vent slowly into atmosphere in an unconfined area or exhaust hood. Refillabletype cylinders should be returned to original supplier with any valve caps and outlet plugs secured and valve protection caps in place. | [Definition]
ChEBI:Tellurium hexafluoride is a tellurium coordination entity. | [Production Methods]
Tellurium hexafluoride (TeF6) is prepared by the direct
fluorination of tellurium metal. It is a by-product of ore
refining. | [Source]
