Self-extinguishing fire extinguishers: choice, characteristics, advantages and disadvantages

Self-extinguishing fire extinguishers are modern devices that can be installed autonomously and which will operate without the efforts of a person. The essence of their action is based on the fact that the glass case is subjected to a temperature pressure. Automatically operating equipment is a module with powder, which is supplemented by a sensor. It is he who reacts to open fire, temperature rise or smoke. These devices should be mounted on water transport or storage facilities.

How to exploit?

Self-extinguishing fire extinguishers have a number of features:

1. Instant response to increased ambient temperature and automatic triggering.
2. Optimal operation at a temperature mode from -50 to +50 degrees.
3. Absence of toxic elements in a powdery substance.
4. Easy installation at low operating costs, as there is no need to install any additional equipment.
5. Energy-independent fire extinguishers that work regardless of whether there are external power supplies.

Instructions for use

Self-extinguishing fire extinguishers are installed where a fire may occur. The instruction for their use is quite simple:

1. Before using, make sure that there are no cracks in the device casing.
2. The glass flask is carefully removed from the holder.
3. The holder is fixed horizontally.
4. OSB should not be located at a height of more than 2 m.
5. The flask is carefully inserted into the holder, which is tightly attached.

OSB-1

OSP-1 self-extinguishing fire extinguishers are hermetically sealed glass vessels filled with a powdered fire extinguishing compound and a special gasifier. As soon as the ambient temperature exceeds the critical point, the powdered filler in the capsule becomes a gas, as a result of which it escapes from it under the influence of high pressure. OSP-1 operates at a temperature above 100 degrees.

OSP-1 self-extinguishing fire extinguishers are characterized by tightness. They are used to extinguish the burning of various substances - solid or liquid, petroleum products, electrical equipment. At the same time, human participation is not required. It is advisable to use these models in addition to portable fire extinguishers or in return for them. Automatic fire extinguishers are good in that they prevent the spread of fire around the surrounding area, which protects not only the premises, but also people who are not required to take part in firefighting. Another version - OSP-2, it can be used at a heating temperature of up to 200 degrees.

"Shar-1"

Fire extinguishers self-operating "Shar-1" can cope with the fire without human intervention. This device can be used as a primary fire extinguishing agent in the case of fires of solid or liquid combustible substances or equipment. It is impossible to apply metal (alkaline and alkaline-earth) fires to extinguish.

The following factors can be attributed to the advantages of this extinguishing agent:

• Do not turn on or press the fire extinguisher: "Shar-1" should simply be thrown into the fire, which even a child can cope with. Since you do not need to turn the device on or off, you can deal with a fire site quickly and safely for health.
• High reaction rate: "Shar-1" reacts to any kind of fire when the temperature inside the premises does not reach the peak.
• Instant response: an automatic fire extinguisher is installed in fire hazardous areas - from switchboards to filling stations and industrial plants.
• Efficiency: "Shar-1" copes with extinguishing fires of different classes.
• Safety of operation: components of a self-extinguishing fire extinguisher are made of soft materials, so when it works there will be no harm to property or people. The product can work even in hands, but not lead to injuries.

Design features of "Shara-1"

Self-extinguishing fire extinguishers "Shar-1" in its design is a device with a special chemical composition, which makes fire extinguishing very effective. Flammable cords on the sides of the ball when they hit the surface of the fire contribute to the activation of the ejection of the powder, which prevents combustion. A cloud of powder is formed all over the fire, which is not dangerous for human health.

Buran

Automatic fire extinguisher is a modern way to protect rooms from fire. The "Buran" model copes well with class A and B fires when extinguishing solid and liquid combustible materials. There are several varieties of a self-extinguishing fire extinguisher of this brand.

The fire extinguisher "Buran 2,5" can be started both in the forced electric start-up mode and in the self-service mode. The original shape allows you to harmoniously fit the product into any interior. Widely used in the protection of various enterprises and premises, mounted in ceilings. According to the design of the fire extinguisher "Buran" is a body in the form of spheres, which are tightly connected with each other. Inside them is a fire extinguishing powder, a gas generator and an electric activator. As soon as a fire occurs, gas is intensively released in the hull, pressure builds up, which leads to the destruction of the shell and the formation of fragments.

Buran-0.5

This fire extinguisher is a shell with a fire extinguishing powder, a gas generating element and an electric activator. On the one hand, the body is tightly closed by a rupture disc, on which notches are marked, it is over them that the membrane begins to burst under the influence of high pressure. The self-extinguishing powder extinguisher works as follows: a current impulse is applied to the activator, resulting in the decomposition of the gasifier and intensive gas evolution. As a consequence, pressure builds up inside the case, the membrane collapses, and the fire extinguishing powder is thrown out to the area that needs protection from fire.

Pros and cons

Most OSP are installed in conjunction with the installation of fire safety sensors, which react to heating, smoke. Characteristics of fire extinguishers as convenient and safe means of protection allows to use them in any premises. It is noteworthy that OSB can also be used in manual mode, especially if operational actions are required. In this case, the flask needs to be broken against a hard surface, and the contents are sprayed by hand.

With all the positive properties, self-conditioning systems can falsely react to an increase in air temperature, for example, due to its natural heating or the operation of the air-conditioning system. In addition, for larger premises it is advisable to mount several fire extinguishers.

Today, these varieties are the most popular, easy to install and maintain and affordable. Modifications of these systems there are many, so you can choose an option that will appeal to the principle of action and location features. Each set of extinguishers is supplemented with a powder fire extinguishing module , a set of fasteners, a passport and a user's manual.
