EXPOSURE EFFECTS OF
CARBON DIOXIDE GAS
Carbon Dioxide is generally regarded as an asphyxiant, in that it displaces Oxygen.
The signs and symptoms of asphyxia are headache, dizziness, shortness of breath, muscular weakness, drowsiness, and ringing in the ears.
10%-12%
These levels of carbon dioxide can cause unconsciousness within
a very short period of time.
Because Carbon Dioxide is heavier than air, (and large leaks will settle initially
in low lying areas) anyone working
in sub-surface or confined areas should be very alert to any presence
of elevated levels of CO2.
Anyone who has been overcome due
to exposure to carbon dioxide gas should be removed from the contaminated area immediately, inhale fresh air or oxygen and seek medical attention.
If breathing has stopped, start artificial respiration at once.
