1. Introduction to IG100 gas fire extinguishing system

my country has clear regulations on the application of gas fire extinguishing systems. GB50016-2006 "Code for Fire Protection Design of Buildings", GB50045-2005 "Code for Fire Protection Design of High-Rise Civil Buildings", GB50098-98 "Code for Fire Protection Design of Civil Air Defense Engineering" and other national standards require that gas fire extinguishing equipment should be installed in places with valuable equipment such as communication rooms, computer rooms, archives, libraries, and generator rooms. Since the signing of the Montreal Protocol, fire extinguishing agents such as Halon 1211 and 1301 that have a destructive effect on the ozone layer have gradually been replaced. With the continuous deepening of the research on Halon alternative gases, nitrogen, as an inert gas fire extinguishing agent, has attracted widespread attention, and corresponding research has been conducted on the fire extinguishing concentration, pressure, and fire extinguishing effect of nitrogen fire extinguishing systems. The IG10 nitrogen fire extinguishing system uses pure nitrogen that is completely derived from the atmosphere as a fire extinguishing agent. IG10 is the main component of air, with an ozone depletion potential of ODP=0, a greenhouse effect potential of GWP=0, and an atmospheric residence time of zero, and has no adverse effects on the environment.

IG100 is colorless, odorless, and non-toxic. It is not only harmless to the human body, but also does not produce any chemical substances during the fire extinguishing process, and will not cause secondary pollution to the equipment. There is no atomization phenomenon when spraying, and it does not hinder the field of vision, which can ensure the orderly and safe evacuation of personnel. The specific gravity of IG10 relative to air is 0.97, which enables it to maintain a constant fire extinguishing concentration after being released in the protected area, thereby ensuring the fire extinguishing effect and effectively preventing re-ignition. It is a safe and environmentally friendly fire extinguishing agent suitable for places where people are often active.

2. Characteristics of nitrogen fire extinguishing agent

The fire extinguishing agent of IG100 nitrogen fire extinguishing system is nitrogen. In the American Fire Protection Association standard NFPA2001, its code is specified as IG100. Nitrogen is a component of air, colorless, odorless, non-corrosive, non-conductive, and no residue after spraying. Nitrogen is not only an environmentally friendly gas, but also has other advantages as follows:

Nitrogen does not change the chemical properties of air; its GWP and ODS values ​​are both 0, in other words, it does not damage the ozone layer and does not cause greenhouse effect. Nitrogen does not react chemically with other substances or mixtures, and it still maintains its own chemical properties after use, and will not cause secondary pollution to other substances. (The chemical properties remain unchanged in any environment).

GWP - Greenhouse Effect Potential

ODP - Ozone Depletion Potential

Nitrogen is not a synthetic product; no chemical reagents are used in the production process of nitrogen, and there is no chemical reagent residue. It is extracted from absolutely dry air and concentrated and liquefied through a special process tower.

The power consumption cost of producing nitrogen is acceptable; the power consumption cost of concentration and liquefaction is about 1 kWh per cubic meter, and the produced N2 is of high purity, without additional purification costs.

There is no atomization phenomenon when IG10 is sprayed, which does not affect the field of vision and facilitates the safe and calm evacuation of personnel. It does not produce condensation and will not damage the equipment due to sudden temperature changes.

IG10 is chemically inert and does not decompose and produce any substances when exposed to high temperature or fire. It has good electrical insulation properties and is very suitable for extinguishing Class E live fires and protecting high-value irreplaceable equipment.

Fire extinguishing principle and applicable occasions

IG100 nitrogen fire extinguishing system adopts the "total flooding" immersion fire extinguishing principle to reduce the oxygen concentration in the protection area to below 15% and extinguish the fire. The fire extinguishing principle of nitrogen is physical fire extinguishing principle. When extinguishing a fire, it is sprayed into a closed protection area to reduce the oxygen concentration in the room to below 15%, so that it cannot support combustion. Nitrogen does not react chemically with any substance in the protection area. After spraying, it returns to the atmosphere without any residue.

3. IG100 nitrogen fire extinguishing system is suitable for extinguishing the following types of fires

Electrical and electronic equipment fires;

Flammable and combustible gas and liquid fires;

Solid fires, such as floors and ceilings;

Buildings with high-value equipment and installations (such as CED, control rooms, etc.);

High-demand cultural venues (libraries, museums, etc.);

4. IG100 nitrogen fire extinguishing system is not suitable for the following fire occasions

Chemicals or chemical mixtures that can be rapidly oxidized in the air, such as nitrocellulose, gunpowder, etc.

Active metals, such as lithium, sodium, potassium, magnesium, titanium, uranium, plutonium, etc.

Chemicals that can be thermally decomposed by themselves, such as certain organic peroxides or amides.
