SAFETY PRECAUTIONS FOR CARBON DIOXIDE
WARNING:
Carbon Dioxide can cause asphyxiation and death in confined, poorly
ventilated areas. Cold Carbon Dioxide gas can cause severe frostbite to the
eyes or skin. Do not touch frosted pipes or valves. If accidental exposure
occurs, consult a physician at once. If a physician is not readily available,
warm the areas affected by frostbite with water that is near body temperature.
KEEP WORK AREA WELL VENTILATED
Carbon dioxide affects the important acid-base balance in the body. Carbon dioxide is formed from
normal functioning of the body, but the body can tolerate increased amounts of carbon dioxide only in
limited concentration. This is recognized in OSHA standards where a Threshold Limit Value of 5,000
parts per million by volume (0.5 percent concentration) has been adopted. For safety, concentrations
above this level should not be permitted; increased concentrations can cause bodily harm or death.
Additionally, carbon dioxide can cause asphyxiation by displacing oxygen resulting in dizziness,
unconsciousness or death.
Ten percent carbon dioxide in air can be endured for only a few minutes; twelve to fifteen percent soon
causes unconsciousness; twenty five percent may cause death if exposure lasts for several hours. Carbon
dioxide cannot be detected by human senses and will be inhaled like air. 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 displace normal air without warning that a
life-depriving atmosphere is developing.
COVER EYES AND SKIN
If released to atmosphere, liquid carbon dioxide will turn to carbon dioxide snow. Accidental contact of
carbon dioxide snow or cold gas with the eyes or skin may cause severe frostbite. Handle liquid so that
it will not vent or spill. Protect your eyes with safety goggles or a face shield. Cover the skin to prevent
contact with snow or cold gas, or with cold pipes and equipment. Protective gloves can be quickly and
easily removed and long sleeves are recommended for protection.
GROUP ALL PIPING
The rapid discharge of liquid carbon dioxide through a line, which is not electrically grounded, will
result in a buildup of static electricity. Contact with this electrical charge could be startling and
potentially dangerous to operating personnel. Such lines should be grounded before use.
NOTE:
For additional information of properties of carbon dioxide and proper handling refer to
CGA pamphlets G-6, "Carbon Dioxide" and G-6.1, "Standard for Low Pressure Carbon
Dioxide Systems at Consumer Sites". These publications are available from the
Compressed Gas Association, 1235 Jefferson Davis Highway, Arlington, VA, 22202.
