HEALTH HAZARD DATA

EMERGENCY OVERVIEW

Trifluoromethane is a colorless, nonflammable, nontoxic gas at temperatures above 298.89°K (25.75°C) at atomospheric pressure. It is shipped in steel cylinders as a liquefied gas under its own vapor pressure of 4 380 kPa (635 psig) at 21.1°C.

SYMPTOMS OF OVER-EXPOSURE

Inhalation: High concentrations of Trifluoromethane so as to exclude an adequate supply of oxygen to the lungs causes dizziness, deeper breathing due to air hunger, possible nausea and eventual unconsciousness. Contact with rapidly evaporating liquid can cause “bums” or frostbite.
