Different fire extinguishing compositions are used to combat fire. Today, the day to the most demanded of them should be considered: water, Goth and foam. In addition to these fire extinguishing compositions, powder mixtures and aerosols are also used, but they are less common.
Fire extinguishing systems in which the above substances are used can be automatic, manual and combined. The most widespread automatic fire extinguishing.
This article will consider gas, water and foamed automatic fire extinguishing. Based on the above, it is precisely such systems that are most common to date.
Water
To date, fire extinguishing with water as a active substance is used to extinguish 90% of all fires. This popularity of the method is due to the fact that it is water that is the safest substance for human health.
It is the prevalence of the method that is the reason that water automatic fire extinguishing can have different execution options. First of all, all installations should be divided into two types:
Aggregate.
Modular using thin -lung water.
The first species, in turn, can be divided into drendrous and sprinkler systems. The differences between them are quite significant:
Firstly, sprinkler systems are always automatic. Their work does not depend on the fire alarm. The irrigators contain in their structure thermal locks or flasks that are destroyed under the influence of the growing temperature. Thus, automatic fire extinguishing is activated.
Secondly, sprinkler systems can be used provided that the temperature in the room where they are set are not dropped below +5 degrees. The fact is that the pipelines of sprinkler systems are always filled with fire extinguishing agents. Drenerman systems are able to work under more severe conditions.
Thirdly, sprinkler automatic fire extinguishing is most often local. Sprinklers are activated in the place where there is a need to extinguish a fire. Drenerman systems are fully activated. In particular, that is why with their help, water curtains are often created, which prevents the spread of fire.
Fire extinguishing modules with thin -posed water are recognized as the most effective, both from the point of view of the fight against fire and saving the fire extinguishing used. They do not need to arrange huge reservoirs.
Foam
Fires extinguishing with foam solutions are most often used if oil or oil products are burning. This is due to the following characteristics of foam fire extinguishing:
Minimum density. Foam is lighter than any oil product and therefore always remains from above.
Fluidity. Even the foam distributed by one nozzle can cover the entire burning area.
High enveloping qualities. Foam reliably overlaps the access of fresh air to the hearth. As a result of this, the fire fades quickly enough.
As the main advantage of foam fire extinguishing, high frequency of the active substance should be highlighted. It can be equal to one hundred units and even more.
Gas
Fire extinguishing using GTV, in particular gas automatic fire extinguishing is the most effective method of combating fire. As a rule, Gotv suppresses fire in less than a minute. Such fire extinguishing is not the most common only because all GTV under certain circumstances can pose a danger to humans.
