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

Self-actuating fire extinguishers are modern devices that can be installed autonomously and which will operate without human effort. The essence of their action is based on the fact that temperature pressure is exerted on the glass case. Automatically working equipment is a powder module, which is complemented by a sensor. It is he who reacts to open fire, fever or smoke. It is advisable to mount these devices on water transport or storage facilities.

How to operate?

Self-operating fire extinguishers have a number of features:

  1. Instant response to an increase in ambient temperature and automatic response.
  2. Optimum operation in temperature conditions from -50 to +50 degrees.
  3. The absence of toxic elements in a powdery substance.
  4. Easy installation at low operating costs, since you do not need to install any additional equipment.
  5. Non-volatility of fire extinguishers that fire regardless of whether there are external power sources.

Instruction for use

Self-extinguishing fire extinguishers are mounted where the occurrence of a fire source is possible. Instructions for their use are quite simple:

  1. Before use, make sure that there are no cracks in the device case.
  2. The glass bulb is carefully removed from the holder.
  3. The holder is mounted horizontally.
  4. OSB should not be located above 2 m.
  5. The flask is carefully inserted into the holder, which is tightly attached.

OSP-1

OSP-1 self-propelled fire extinguishers are hermetically sealed glass vessels that are filled with a powdery extinguishing agent and a special gasifier. As soon as the ambient temperature exceeds a critical point, the powdery filler in the capsule becomes gas, as a result of which it breaks out under the influence of high pressure. OSP-1 is triggered at temperatures above 100 degrees.

OSP-1 self-propelled fire extinguishers are leakproof. They are used in extinguishing fires of various substances - solid or liquid, petroleum products, electrical equipment. Moreover, human participation is not required. It is advisable to use these models in addition to portable fire extinguishers or to replace them. Automatic fire extinguishers are good in that they prevent the spread of fire in the surrounding area, which protects not only the premises, but also people who do not need to take part in fire fighting. Another variety is OSP-2, it can be used at a heating temperature of up to 200 degrees.

"Ball-1"

Self-operating fire extinguishers "Shar-1" can cope with a fire without human intervention. This device can be used as a primary fire extinguishing agent for foci of ignition of solid or liquid combustible substances or equipment. It can not be used to extinguish metal ignitions (alkaline and alkaline earth).

OSB 1 self-operating fire extinguishers

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

  • There is no need to turn on or press the fire extinguisher: β€œBall-1” should just be thrown into the fire, which even a child can handle. Since it is not necessary to turn the appliance on or off, the fire can be dealt with quickly and safely.
  • High reaction rate: Shar-1 reacts to any fire when the indoor temperature does not have time to reach a peak.
  • Instant response: an automatic fire extinguisher is installed in fire hazardous areas - from switchboards to gas stations and industrial enterprises.
  • Efficiency: β€œShar-1” copes with extinguishing fires of different classes.
  • Operational safety: the components of a self-extinguishing fire extinguisher are made of soft materials, therefore, during its operation there will be no harm to property or people. The product may work even in the hands, but not result in personal injury.

Design features of the "Ball-1"

Self-extinguishing fire extinguishers "Shar-1" in their design are a device with a special chemical composition, due to which fire extinguishing is very effective. Highly flammable cords on the sides of the ball when exposed to fire contribute to the activation of the release of powder, which prevents combustion. A powder cloud is formed throughout the entire amount of the quenching, which is not harmful to human health.

Buran

An automatic fire extinguisher is a modern way of protecting 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 self-extinguishing fire extinguisher of this brand.

The Buran 2.5 fire extinguisher can be started both in the forced electric start mode and in the self-operation mode. The original form allows you to harmoniously fit the product into any interior. It is widely used in the protection of various enterprises and premises, mounted in ceilings. By design, the Buran fire extinguisher is a housing in the form of spheres that are tightly interconnected. Inside them is a fire extinguishing powder, a blowing agent and an electric activator. As soon as a source of ignition occurs, gas is intensely released in the housing, pressure builds up, which leads to the destruction of the housing and the formation of fragments.

Buran-0.5

This fire extinguisher is a housing with a fire extinguishing powder, a gas generating element and an electric activator. On the one hand, the casing is tightly closed by a bursting disc, on which notches are applied - it is through them that the membrane begins to burst under the influence of high pressure. A self-extinguishing powder fire extinguisher operates as follows: a current pulse is applied to the activator, as a result of which the blowing agent decomposes and intense gas evolution occurs. As a result, pressure builds up inside the case, the membrane collapses, and fire extinguishing powder is thrown to the area that needs protection from fire.

Pros and cons

Most often, OSBs are installed in combination with the installation of fire safety sensors that respond to heating, smoke. The characteristic of fire extinguishers as a convenient and safe means of protection allows you to use them in any room. It is noteworthy that OSB can be used in manual mode, especially if prompt action is required. In this case, the flask must be broken on a hard surface, and the contents are sprayed manually.

self-propelled powder fire extinguisher

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

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