NONTOXIC, BUT THE RELEASE OF A LARGE AMOUNT IN A CONFINED AREA
COULD DISPLACE THE OXYGEN IN AIR NECESSARY TO S UPPORT LIFE.
Effects of Overexposure:EFFECTS OF OVEREXPOSURE TO HIGH CONCENTRATIONS
SO AS TO DISPLACE THE OXYGEN IN THE AIR NECESSARY FOR LIFE ARE
HEADACHE, DIZZINESS, LABORED BREATHING AND EVENTUAL
UNCONSCIOUSNESS. BREATHING MIXTURES OF HELIUM WITH ADEQUATE OXYGEN
TO SUPPORTLIFE MODIFIES THE VOICE SO THAT IT IS HIGH PITCHED.
