Although nitrogen is nontoxic and largely inert, it can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life.

尽管氮无毒且很大程度上不活泼，通过取代空气中的氧，使之下降到维持生命所必须的水平以下它可以为简单的窒息物。

Inhalation of nitrogen in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness, and death.

过量吸入氮会导致眩晕、恶心、呕吐、失去知觉和死亡。

Death may result from errors in judgment, confusion, or loss of consciousness, which prevents self-rescue. At low oxygen concentrations, unconsciousness and death may occur in seconds and without warning.

死亡可能来源于错误的判断、精神混乱或者阻止了自救的失去知觉。在低氧浓度情况下，意识不清和死亡会在几秒钟内发生，而且没有警告。
