Time-Weighted Average Exposure Values
Short-Term Exposure Values
EXPOSURE EFFECTS OF
CARBON DIOXIDE GAS
Exposure to low concentrations of Nitrogen Dioxide (as little as 25ppm
over an 8 hour period) will likely not produce immediate serious effects,
but the effects of exposure will
set in as much as 5 to 48 hours later.
Just a few breaths of NO2 at as little as 200ppm may produce fatal results after 5-8 hours have passed.
Some of the symptoms and effects
of exposure include; initially, headache, nausea, dizziness, vomiting and respiratory discomfort. Increasingly, these symptoms will get worse with time and the victim of exposure will find their ears and lips turn blue, respiration will become more difficult and accelerated.
If untreated, death is likely to occur from pulmonary edema.
