What are the hazards of nitrogen gas?
Being odorless, colorless, tasteless, and nonirritating, nitrogen has no properties that can warn people of its pres- ence. Inhalation of excessive amounts of nitrogen can cause dizziness, nausea, vomiting, loss of consciousness, and death (Table 2).
Is dry nitrogen hazardous?
The gas can cause asphyxiation without warning by replacing the oxygen in the air. Based on the hazard and potential for exposure, select a respirator that meets the appropriate standard or certification.
Is N2 gas flammable?
Nitrogen gas is colorless, odorless and non-flammable. It is non-toxic. The primary health hazard is asphyxiation by displacement of oxygen. Maintain oxygen levels above 19.5%….Material Safety Data Sheet. Liquid Nitrogen.

Is nitrogen considered a toxic gas?
Nitrogen is a colorless gas with no odor or taste. It is not toxic; the only health hazard is that it is an asphyxiant and may displace oxygen in a workplace atmosphere. Routes of Exposure: Nitrogen is not toxic by any route. Asphyxia may result if the oxygen concentration is reduced to below 18% by displacement.

Why is nitrogen not flammable?
Nitrogen is not flammable. It has a very strong, triple bond that is stable and causes very low reactivity. It will not catch fire in most cases.
Can nitrogen gas catches fire?
No, Nitrogen does not burn under normal circumstances. It is the most abundant element in the atmosphere; however, it will not combust. It is primarily due to its poor thermal conductivity as compared to hydrogen and oxygen. It cannot even sustain a flame at atmospheric level.
How does nitrogen put out fire?
Nitrogen operates as a fire suppressant by reducing the oxygen content within a room to a point at which the fire will extinguish, without compromising the safety of individuals present in the room. Nitrogen will not decompose or produce any by-products when exposed to a flame.
