Ancient and modern water fire extinguishing. Offer from Alfa TV Com. Scope and purpose

It will be necessary to establish cooperation with other rescue agencies such as gas, police, ambulance etc. Flames emerging from pipelines or process equipment can be tempered by powerful water jets using their energy. flow pressure extinguishing agent must be at least equal to the outlet gas pressure. Repayments should be carried out when it is possible to close the gas outflow.

Gas tanks, heated elements and pipelines, as well as objects in the immediate vicinity must be cooled. All activities must be carried out with special attention to the observance of safety conditions. Use any lid if possible, but avoid voids.

After the flame is extinguished, the extinguishing stations must remain in their occupied positions until it is determined that there is no possibility of re-ignition. When technical gases When recognizing events, you must define the following.

The type of gas flared or released to the environment, as well as gases in an area exposed to heat. The degree of danger to people, directions of care and place of refuge. Possibility of explosion or fire and danger to environment. Possibility to remove hazardous substances from the endangered area.

Taking measures to extinguish gas storage facilities, people must unload from the danger zone, and then intensively cool the storage facility and the surrounding area. Quenching is usually carried out using tight quenching. When removing the cylinders, move them very carefully, avoiding impacts, from the legs of the cylinder. Recall that the object in which the cylinders are located, we are approaching strong structural components that work open space. Don't stop at the light holes. When the cylinders are on a ramp or platform vehicle, we move by leaning below their level.

We put out fire extinguishers. Let's highlight a few words for acetylene bottles. Acetylene itself is a gas composed of carbon and hydrogen. In its pure form, it is an odorless gas, and the characteristic slight smell of garlic is added to it by hydrogen sulfide and ammonia. It is a very dangerous gas because an explosion is dangerous if the pressure is too high and after mixing with air. The ignition source can be any energy stimulus, even an electrostatic spark. Inflammation of the cylinder can also cause the flame to be deflected away from the connected burner.

In case of acetylene leakage or cylinder fire. When an event occurs in free space, specify a 300 megawatt safety zone. Remove people from the area and from the building and eliminate possible sources of ignition. The cylinders that have been warmed up so far can be used carefully, avoiding bumps and bumps, and move in a safe place.

Before moving the cylinder, check the degree of heating before hand. If any warm place is found, we leave the bottle in place to cool it down intensively. The positions are protected and preferably do not require maintenance. Checking the degree of heating of the cylinder is carried out after at least one hour of cooling from the moment the fire was extinguished, if the cylinder is still a place of heating or water vapor rises from it, continue to cool for another half an hour. Cooling can be interrupted when the surface of the cylinder remains wet and cold for half an hour.

Do not tamper with valves previously exposed to heat. In cases where we have a bottle of flammable acetylene gas, we evacuate the environment and try to close the valve. If this operation fails, the flame does not go out, allowing the gas to burn out. We will extinguish when the flame reaches the edge of the cylinder.

When working with factory bottles with water protection fire extinguishers, these devices should be started if we do not supply water from the wires, closing them with each of the cylinders. Slamming the cylinders after carefully moving the sink for at least 12 hours. Pay attention to the vertical or lateral position of the cylinder outlet.

Secure neighborhoods with the ability to transfer fragments or entire cylinders or pieces of process equipment, as well as heat wave effects that are short-lived but pose a threat to people and objects in their path. The village is a farm building, that is, residential, utility and livestock buildings in family farms, farm or horticultural farms and forestry. In addition to residential buildings, there are also important buildings for the construction of workshops and the storage of materials, tools and equipment used for other buildings, as well as utility buildings, as well as the storage of materials and equipment for agricultural production and agricultural products.

There are a number of other facilities such as utilities, manufacturing and storage companies, communication facilities, sacred buildings, and others. Fires in rural areas are still distinct from urban fires as a result of widely used flammable building materials. In addition, most of them are mostly low-rise, stand-alone, rarely serialized buildings. Depending on the region of the country, there is a variety of ways to build and use a building.

A characteristic feature of fires is the rapid formation of external fires that threaten the environment. Sometimes they cover much more space than in the city, mainly where firewood predominates. The reason for the spread of fire in rural areas may be.

Flammable and dense buildings and accumulation a large number flammable materials that contribute to direct flame exposure to the surroundings. Impact of thermal radiation on the environment. In case of external fires, flying fires occur. Fires in daylight may be difficult to see; Formation of fire bridges formed when combustible material is present, propagating a fire from its original place of origin to other locations within the fire's reach.

Due to the possibility of rapid development and spread of fire, it is necessary to pay attention to the danger to people and animals, and in case of its immediate adoption of evacuation or rescue actions. Fire fighting most often occurs from the ground level and primarily involves fire suppression and fire management. effective protection surroundings. Strive to block the fire in the main direction of spread. Where there are conditions and need - fire extinguishers should be occupied equal or higher, using adjacent objects or ladders freed.

Putting out a fire can prevent a temporary or complete absence of water. When there is a break in the water supply, demolition, scrap, stairs and laid heat and fire fighting must be stopped, which limits the decay of the resulting flame. Early application of the foam can give good effects.

V countryside we often encounter fires of infected fruits. The main action is to break the flame to reduce the danger to the environment and expose yourself to the landfill, and then continue to extinguish with scattered streams of water to increase the extinguishing surface and reduce water loss. Wetting agents are excellent for extinguishing, including solutions of aqueous foaming agents. If the combustion process has moved to a pile, then, apparently, the extinguished fire is resumed after a while, despite the constant flow of water currents.

Thus, using forks, grinding machines, scavengers, strip the pile on the ground and after scattering into thin layers in a large space - to suppress diffuse water flows. We respect you before we climb the stairs. The burning of its interior, caused not only by the destruction of the material caused by fire, but also by possible self-ignition, creates the danger of collapse. If for some reason this is necessary, then the rescuer should be protected by a rope, and at the top of the repository should be a deck of boards, ladders or even gates.

By reducing free-standing or threshing spot fires, the possibility of fire spreading on the ground must be reduced. Remove agricultural machinery and equipment there, endangered. Whereas a single staircase standing alone where there is no danger to the environment is not always economically justified. It is worth considering the possibility of fighting the fire and burning the stoker for free.

Specific fires that we may encounter are stump agricultural fires. Grain during ripening is a mass of flammable material. The fire spreads rapidly, covering large areas, endangering surrounding buildings, forests and other objects. In similar grassland fires, people and animals also kill. The fire comes with a fairly high flame and irregularity. Sometimes it is a fast movement of the fire, sometimes its dynamics is reduced, and this is a good opportunity to take fire extinguishers at this time.
