enough oxygen for breathing can cause dizziness, unconsciousness, or even death.

Nitrogen, a colorless, odorless, and tasteless gas, cannot be detected by the human

senses and will be inhaled normally. Without adequate ventilation, the expanding

nitrogen will displace the normal air resulting in a non-life-supporting atmosphere.

Dispose of Waste Liquid Nitrogen Safely

Dispose of waste liquid nitrogen out-of-doors where its cold temperature cannot

NOTE: Argon is an inert gas whose physical properties are very similar to those of

nitrogen. For handling of liquid argon, follow the safe practices described for the

handling and use of liquid nitrogen.

Safety Precautions for Liquid Carbon Dioxide

WARNING: CARBON DIOXIDE CAN CAUSE ASPHYXIATION AND DEATH IN CONFINED, POORLY VEN-

TILATED AREAS.

COLD GAS CARBON DIOXIDE CAN CAUSE SEVERE FROSTBITE TO THE EYES OR SKIN. DO NOT TOUCH

FROSTED PIPES OR VALVES. IF ACCIDENTAL EXPOSURE TO THESE GASES OCCURS, CONSULT A PHY-

SICIAN AT ONCE. IF A PHYSICIAN IS NOT READILY AVAILABLE, WARM THE AREAS AFFECTED BY

FROSTBITE WITH WATER THAT IS NEAR BODY TEMPERATURE

if exposure lasts for several hours. Carbon dioxide cannot be detected by the hu-

man senses and will be inhaled normally. Carbon dioxide is heavier than air and

will accumulate in low lying areas. Carbon dioxide concentrations will be greater

in these areas. If adequate ventilation is not provided, carbon dioxide may dis-

place normal air without warning that a life-depriving atmosphere is developing.
