Physical Description | Tellurium hexafluoride is a colorless gas with a repulsive odor. It is very toxic by inhalation and skin absorption. When heated to high temperatures, it may emit toxic fluoride and tellurium fumes. It is heavier than air. Under prolonged exposure to fire or intense heat the containers may violently rupture and rocket. It reacts with water to yield toxic vapors.

Human Toxicity Excerpts

Tellurium hexafluoride has caused headache, chest pain, and dyspnea. It is considered toxic by inhalation and may produce pulmonary edema and death.

Non-Human Toxicity Excerpts

/RABBITS, GUINEA PIGS, RATS, & MICE WERE EXPOSED TO 1 PPM FOR 5 DAYS/ ... WITHOUT EFFECT ... WHEREAS SERIOUS EFFECTS WERE SEEN AFTER A SINGLE EXPOSURE OF /1 PPM FOR 4 HR/ ... TOLERANCE DEVELOPMENT AGAINST THE ACUTE EFFECTS WOULD SEEM A REASONABLE INTERPRETATION.

Populations at Special Risk

TELLURIUM HEXAFLUORIDE CAUSES RESPIRATORY IRRITATION. IN PERSONS WITH IMPAIRED PULMONARY FUNCTION, ESPECIALLY THOSE WITH OBSTRUCTIVE AIRWAY DISEASES, THE BREATHING OF TELLURIUM HEXAFLUORIDE MIGHT CAUSE EXACERBATION OF SYMPTOMS DUE TO ITS IRRITANT PROPERTIES.

Antidote and Emergency Treatment

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in respiratory arrest.
