EMERGENCY OVERVIEW Tetrafluoromethane is an odorless, colorless non-flammable, liquefied gas. Tetrafluoromethane can cause central nervous system depression after inhalation exposures. Symptoms of such over-exposure can include drowsiness, fatigue, and weakness. At high concentration, the gas can act as an asphyxiant, by displacing oxygen. Therefore, exposure to high concentration of this gas can be fatal. Frostbite can be caused by contact with rapidly expanding gases or the liquefied gas. This gas is not flammable and not reactive in normal emergency response situations. However, if involved in a fire, this product can decompose to produce toxic gases (i.e. hydrogen fluoride, phosgene). |
