Self-working fire extinguishers are moderndevices that can be installed autonomously and that will work without human effort. The essence of their action is based on the fact that temperature is applied to the glass case. Automatically operating equipment is a module with powder, which is complemented by a sensor. It is he who reacts to open fire, fever or smoke. These devices should be mounted on water transport or storage facilities.
Self-working fire extinguishers have a number of features:
Self-propelled fire extinguishers are mounted where possible the occurrence of the fire. Instructions for their use is quite simple:
Самосрабатывающие огнетушители ОСП-1 – это hermetically sealed glass vessels, which are filled with powdered fire extinguishing composition and a special blowing agent. 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 is pulled out under the influence of high pressure. OSP-1 works at temperatures above 100 degrees.
OSP-1 self-fire extinguishers are differenttightness. They are used in extinguishing the fire of various substances - solid or liquid, petroleum products, electrical equipment. In this case, human participation is not required. It is advisable to use these models in addition to portable fire extinguishers or in exchange for them. Automatic fire extinguishers are good because 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 version - OSP-2, it can be used at a temperature of heating up to 200 degrees.
Self-working fire extinguishers "Shar-1" allowcope with a fire without human intervention. This device can be used as a primary fire extinguishing agent in case of fires of solid or liquid combustible substances or equipment. Do not use to extinguish fires of metals (alkali and alkaline earth).
The advantages of this fire extinguishing agent include the following factors:
Self-working fire extinguishers "Ball-1"structures are a device with a special chemical composition, making 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 burning. Throughout the extinguishing volume, a cloud of powder is formed, which is not dangerous to human health.
Automatic fire extinguisher is modernway to protect the premises from fire. The Buran model copes well with Class A and B fires when extinguishing solid and liquid combustible materials. There are several types of self-working fire extinguisher of this brand.
Огнетушитель «Буран 2,5» может быть запущен как в the mode of forced electric start-up, and in the self-working mode. The original form allows you to harmoniously enter the product in 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 body in the form of spheres, which are tightly interconnected. Inside of them is a fire extinguishing powder, a gasifier and an electrical activator. As soon as a source of ignition arises, gas is intensively emitted in the body, pressure builds up, which leads to body destruction and the formation of fragments.
Этот огнетушитель представляет собой корпус с fire extinguishing powder, gas generating element and electric activator. On the one hand, the casing is tightly closed with a bursting disc, on which notches are applied - it is precisely along them that the membrane begins to burst under the influence of high pressure. The self-propelled powder fire extinguisher works as follows: a current pulse is applied to the activator, resulting in decomposition of the gasifier and intense gassing. As a result, pressure builds up inside the casing, the membrane collapses, and fire extinguishing powder is ejected onto the area that needs protection from fire.
Most often, PCBs are installed in conjunction withinstallation of fire safety sensors that respond to heating, smoke. The characteristic of fire extinguishers as convenient and safe means of protection allows their use in any premises. It is noteworthy that the PCB can be used in manual mode, especially if operational actions are required. In this case, the flask must be broken on a hard surface, and the contents sprayed manually.
With all the positive properties,self-generating systems may falsely react to an increase in air temperature, for example, due to its natural heating or air conditioning operation. In addition, for large rooms it is advisable to install several fire extinguishers.
Today, these varieties are the mostpopular, easy to install and maintain and affordable. There are many modifications of these systems, so you can choose an option that will appeal to the principle of operation and location features. Each set of fire extinguishers is supplemented with a powder fire extinguishing module, a set of fasteners, a passport and an instruction manual.
