Nitrogen Dioxide is a red-brown, toxic gas at room temperature.

 Exposure Limits   (As published under under the Ontario Occupational Health and Safety Act.)


 Exposure Effects Of Nitrogen Dioxide

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.
