Freon
The most common gases used in fire extinguishing at present are freons 125 and 227ea. Studies have shown that the time of safe exposure of people to freons (even at concentrations one third higher than the fire extinguishing concentration) is at least 30 seconds, which allows for evacuation in most cases.
Therefore, they are usually used in SGP for rooms where people are constantly present.
In demand where the priority is the preservation of material assets that can be damaged by water, foam or aggressive chemicals:
- art objects
- archival documents
- electronic devices
Freon 227ea is low-toxic for humans - inhaling freon vapors for several minutes will not lead to disruption of life.
HFC 227ea does not displace oxygen (as compressed gases do, diluting the atmosphere)
Freon 125 is as effective as freon 227ea. Just like freon 227ea, freon 125 does not damage documents and sensitive electronics, and therefore is actively used where careful handling of objects located indoors is necessary. Its advantages include excellent ability to extinguish smoldering materials, but it cannot be used in rooms where people are constantly present, as it is toxic.
No type of freon (including freon 227ea and freon 125) does not conduct electricity; this substance is chemically inert and does not cause corrosion, due to which it is classified as “pure gases”.
Freon 125 and freon 227ea are designed to extinguish a wide variety of fires:
- class A (combustion of solids)
- class B (combustion of liquid substances)
- class C (combustion of gaseous substances)
- class E in initial stage development (electrical installations under voltage up to 110 kV)
Freons have a relatively low storage pressure, making them easy to transport and store. That is, less space is required to install a gas fire extinguishing system based on them. The supply of refrigerants from the cylinder occurs under the pressure of a propellant gas, which can be nitrogen or dried air.
Carbon dioxide CO 2 (carbon dioxide)
A colorless gas with a density of 1.98 kg/m3, odorless and non-flammable for most substances. The mechanism by which carbon dioxide stops combustion is its ability to dilute the concentration of reactants to the point where combustion becomes impossible.
Carbon dioxide can be released into the combustion zone in the form of a snow-like mass, thereby exerting a cooling effect. One kilogram of liquid carbon dioxide produces 506 liters. gas The fire extinguishing effect is achieved if the concentration of carbon dioxide is at least 30% by volume.
Requires the use of weighing devices to control the leakage of fire extinguishing agent, usually a tensor weighing device.
Traditionally used to protect industrial facilities (only in premises where personnel are absent or can only be present periodically):
- diesel
- flammable liquid warehouses
- compressor
Such objects are characterized by intensive fire development due to the presence of class B fire load according to GOST 27331 ( diesel fuel, oils, gasoline, etc.), cables, electrical equipment for high voltage, as well as a number of other features.
Cannot be used to extinguish alkaline earth, alkali metals, some metal hydrides, developed fires of smoldering materials.
A colorless and odorless liquid, sometimes called "dry water". Obtained by the 3M Corporation during research to replace freon 114 (banned in 1993). First demonstrated in 2004. This is a new generation gas used to extinguish fires, an innovative substance that is safe and effective remedy fire fighting.
Advantages:
- safety and harmlessness to people (to a high degree)
- safety for devices and equipment with electronics, documents, furniture and interior items
- ease of transportation and use (without “dangerous goods” marking)
- compact design of the fire extinguishing system
- high degree of efficiency in extinguishing fire

Gas fire extinguishing composition Freon 125HP
Gas fire extinguishing agent Freon 125ХП is a chemical flame retardant. The mechanism of fire extinguishing with freons consists mainly in the effect of this gaseous fire extinguishing agent on the rupture of radical bonds of the physicochemical chain reaction combustion, in suppressing the “active centers” of this reaction and creating a non-flammable environment in the protected volume.
Gas fire extinguishing composition Freon 125ХП is environmentally friendly and does not affect ozone layer, interior items, electrical equipment and material assets. Filling factor 0.9kg/l.
In addition, Freon 125ХП has maximum thermal stability compared to other refrigerants; the thermal decomposition temperature of its molecules is more than 900°C. The high thermal stability of Freon-125HP allows it to be used to extinguish fires of smoldering materials, because at the smoldering temperature (usually about 450°C) thermal decomposition practically does not occur.
Freon 125HP (Pentafluoroethane, C2F5H, Halon 25, FE-25, R125, HFC-125) can be used to extinguish:
Electrical equipment fires;
Fires of flammable liquids and gases (equipment rooms and pump rooms);
Fires in premises where expensive devices and equipment are concentrated (CED, operating rooms, etc.);
Fires in valuable storage areas.
Gas fire extinguishing composition Freon 227EA
HFC-227ea is a fire extinguishing agent from the freon class. It is most widely used in world practice to protect objects where the safety of material assets is of paramount importance. HFC-227ea is a colorless, tasteless and odorless gas. It is registered in NFPA 2001 and ISO 14520 as HFC-227ea and is sold under the brand names FM 200, Solkaflam 227, Novalon, etc. Chemically, HFC-227ea is heptafluoropropane and has the chemical formula CF3CHFCF3.
In the cylinder, HFC-227ea is in a liquefied state. When leaving the cylinder, HFC-227ea evaporates, reducing the ambient temperature, as for all gases of the freon class, the decrease in temperature is one of the fire extinguishing factors for HFC-227ea. Another factor is chemical inhibition of the combustion reaction.
The undoubted advantage of HFC-227ea is its chemical inertness. It does not conduct electricity, does not cause corrosion of metals and destruction of organic compounds, which allows it to be classified as a group of so-called “pure gases”.
HFC-227ea has regulatory fire extinguishing concentrations of about 7.5%, which is lower than its NOAEL rating (9%). This means that when used as a fire extinguishing agent, it is safe for humans. HFC-227ea is 1.4 times heavier than water, so its maximum filling factor is 1.15 kg/l, which allows the number of cylinders in a fire extinguishing system using it to be reduced to a minimum.
Physico-chemical data of HFC-227ea:
- Molecular weight 170 a.u.
- Boiling point at a pressure of 1 bar - 16.4 ° C
- Liquid density at a temperature of 25 °C - 1407 kg/m3
- Gas density at a pressure of 1 bar and a temperature of 20 ° C - 7.28 kgm3
- Saturated vapor pressure at 25 °C - 3.91 bar
- Fire extinguishing concentration for class B fire 7.2 vol.%
- NOAEL- 9/%.
Toxicity level NOAEL - No Observed Adverse Effect Level - the highest concentration of GFFS at which no harmful psychological or toxicological effect on humans is observed.
- HFC-227ea has an ozone depletion potential of zero and a global warming potential of 3500.
