As a new type of fire extinguishing agent, liquid nitrogen is non-toxic to human body, friendly to the atmosphere and efficient in fire extinguishing. Because of its strong cooling ability, inerting ability and good asphyxiation effect, it is suitable for the fire extinguishing in utility tunnel.
Why nitrogen Cannot be used as fire extinguisher?
The extinguishing effect of inert gases such as argon, nitrogen and carbon dioxide (in principle, this is not an inert gas and is therefore unsuitable for class D fires) is achieved through the displacement of atmospheric oxygen. … In most cases the fire will extinguish after a reduction of oxygen to approx. 13% volume.
What can I use instead of a fire extinguisher?

Is nitrogen a flammable gas?
EMERGENCY OVERVIEW: Nitrogen is a colorless, odorless, non-flammable gas, or a colorless, odorless, cryogenic liquid. The main health hazard associated with releases of this gas is asphyxiation, by displacement of oxygen. … The liquefied gas can cause frostbite to any contaminated tissue.
Can you use fire extinguisher on electrical fire?
Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment. Both monoammonium phosphate and sodium bicarbonate are commonly used to fight this type of fire because of their nonconductive properties.
Is baking soda used for fire extinguishers?
When the fire extinguisher is operated by pressing the knob on it, the sulphuric acid gets mixed with sodium bicarbonate solution producing a lot of carbon dioxide gas. … Hence, sodium bicarbonate is used in fire extinguishers.
What happens if we breathe nitrogen gas?
According to Dr RK Singal, head (internal medicine) at BLK Super Specialty Hospital in the capital, nitrogen gas can prove catastrophic and fatal if inhaled in large quantity because body will be left oxygen-deprived. “Depending on the dose of nitrogen inhaled, it can lead to full body paralysis to instant death.
Is nitrogen bad for the body?
High nitrogen uptake can cause problems in the thyroid gland and it can lead to vitamin A shortages. In the animal stomach and intestines nitrates can form nitroamines; dangerously carcinogenic compounds.
