Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:NITROGEN IS A SIMPLE ASPHYXIANT.
NITROGEN IS NONTOXIC, BUT IF RELEASED IN QUANTITY IN A CONFINED
SPACE, IT CAN REDUCE THE OXYGEN LEVEL TO BELOW THAT NECESSARY TO
SUSTAIN LIFE. CONTACT WITH LIQUID NITR OGEN MAY CAUSE FROSTBITE OR
FREEZING OFTHE TISSUE.
Explanation of Carcinogenicity:MFR GAVE THE ABOVE LISTINGS ON THE MSDS
BUT NO OTHER COMMENTS WERE RECORDED.
Effects of Overexposure:EFFECTS OF HIGH CONCENTRATIONS WHICH REDUCE
OXYGEN TO BELOW THAT NECESSARY FOR LIFE: LOSS OF BALANCE, TIGHTNESS
IN FRONTAL AREA OF FOREHEAD, TINGLING OF TONGUE,FINGERTIPS,TOES,
WEAKENED SPEECH, INABIL ITY TO UTTER SOUNDS, REDUCED ABILITY FOR
MOVEMENT OR CONSCIOUSNESS, LOSE OF TACTILE SENSATION, INCREASED
MENTAL ACTIVITY

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR SELF-
CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR EMERGENCY
USE.
Ventilation:LOCAL EXHAUST VENTILATION SUFFICIENT TO PREVENT REDUCTION
OF OXYGEN CONTENT OF AIR TO BELOW 19.5%.
Protective Gloves:PROTECTIVE GLOVES OF ANY MATERIAL
