Intoxications resulting from asphyxiate gases, such as nitrogen can cause hypoxia and even death. We present a case of a patient with nitrogen intoxication due to inadvertent industrial exposure. In this case, the patient survived and the outcome was different from those reported in the literature. For patients presenting to the emergency department from a workplace with a history of loss of consciousness after using of self-contained breathing apparatus, possibility of nitrogen or other simple asphyxiate gas intoxication should be considered seriously.
