Health Hazards Acute and Chronic:NITROGEN IS DEFINED AS A SIMPLE
ASPHYXIANT. OXYGEN LEVELS SHOULD BE MAINTAINED AT GREATER THAN 18
MOLAR PERCENT AT NORMAL ATMOSPHERIC PRESSURE WHICH IS EQUIVALENT TO
A PARTIAL PRESSURE OF 135 MM HG.
Explanation of Carcinogenicity:THIS COMPOUND CONTAINS NO INGREDIENTS AT
CONCENTRATIONS OF 0.1% OR GREATER THAT ARE CARCINOGENS OR SUSPECT
CARCINOGENS.
Effects of Overexposure:EFFECTS OF EXPOSURE TO HIGH CONCENTRATIONS SO
AS TO DISPLACE THE OXYGEN IN AIR NECESSARY FOR LIFE MAY INCLUDE
ANY, ALL, OR NONE OF THE FOLLOWING: LOSS OF BALANCE OR DIZZINESS;
TIGHTNESS IN THE FRONTAL AREA OF THE FOREHEAD; TINGLING OF THE
TONGUE, FINGERTIPS OR TOES; WEAKENED SPEECH; REDUCED CONSCIOUSNESS;
AND OTHERS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

First Aid:INHALATION: CONSCIOUS PERSONS SHOULD BE ASSISTED TO AN
UNCONTAMINATED AREA AND INHALE FRESH AIR. QUICK REMOVAL FROM THE
CONTAMINATED AREA IS MOST IMPORTANT. UNCONSCIOUS PERSONS SHOULD BE
