Fixed extinguishing systems for local risks - IFSEC Global
The extinguishing agent is a pre-mix foam solution that forms a coating over the liquid which has caught fire to exclude oxygen, provide cooling and to prevent fuel spread and re-ignition. In a petrol station forecourt in Spain, for example, a fixed automatic system – based on that described above – covers an area of approximately 12 square metres of vehicle lane, or the area adjacent to

The Original Clean Agent: Carbon Dioxide Systems
Carbon Dioxide (CO 2) systems are one of the oldest types of gaseous fire suppression systems.CO 2 is very inexpensive, requires no cleanup, and can be applied to a broad range of fire hazards. The major disadvantage associated with CO 2 systems is that the concentration required to extinguish a fire will not support human life, and for this reason, it can no longer be used in occupied enclosures.

What is the best fire extinguisher for a Class C fire? - …
Whereas the Carbon Dioxide fire extinguisher is only capable of extinguishing Class B and Class C fires. If there is a chance that a Class A fire may occur in the office or building where the fire extinguisher will be used, it is better to get the Halotron fire extinguisher.
Why is it that even when nitrogen and carbon dioxide …
The primary reason why CO2 is used as an extinguisher is that it''s denser than air, and hence displaces possible supply of O2 to the source of our deadly fire by forming a sort of a ''blanket'' around it…. Now, density of N2 is around 1.2 kg/m^3
12.4: Phase Diagrams - Chemistry LibreTexts
For example, carbon dioxide has a low critical temperature (31 C), a comparatively low critical pressure (73 atm), and low toxicity, making it easy to contain and relatively safe to manipulate. Because many substances are quite soluble in supercritical CO 2 , commercial processes that use it as a solvent are now well established in the oil industry, the food industry, and others.
The extinguishing properties of Sinorix extinguishing systems with natural agents are based on displacing oxygen in the protected area (inertization): Flooding the area with nitrogen, argon or carbon dioxide lowers the percent by volume of oxygen to typically 13.8

This extinguishing agent is clean, non-corrosive and leaves no residues so it''s no damaging to electrical equipment and machinery. This type of extinguisher is higly pressurized with carbon dioxide, which is a non-flammable inert gas ( a pressure at about 55/60 bar at 20° ).
Fire Suppression Agent Selection - Sprinkler Age
Carbon dioxide is an oxygen diluting agent and does not break down like clean agents. Therefore, the code allows it to take up to 2 minutes to achieve the design concentration. Because of this, we can easily extend the discharge and maintain the concentration with extra gas for several minutes.
