Need for testing

Testing of fire-fighting equipment, which undoubtedly includes hydrants, is an obligatory part of preventive maintenance, during which various problems that could lead to tragedy can be discovered and subsequently eliminated. When checking a hydrant, first of all, pay attention to its proper supply of water. There is a pressure gauge on the barrel of the water meter, the readings of which also need to be checked periodically. These inspections are carried out every 6 months and only in the warm season. Temperature and climatic factors are regulated by GOST 15150. When checking a hydrant, the following items are subject to inspection: the sign indicating the equipment, the nipple thread, the hydrant body itself and the drain channel. The ability of the hydrant to release water is carried out during the period of greatest load. It is also important to check the radius covered by the equipment, which should be sufficient for normal maintenance of the objects assigned to it. After testing with a fire hydrant, a report must be drawn up, which remains with the owner of the object (the building served by the hydrant).

When checking internal fire water supply systems, special attention is paid to fire hydrants and flywheels. Fire hydrants must be in good working order, because... they are an important element of the whole fire protection system. The diameter of fire hydrants should be similar to the diameter of the valves used. When checking, pay attention to the level of water flow required to extinguish the fire (fire) and the height of the jet. The data obtained during the tests must fit into the SNiP standard 2.04.01-85. Such work is carried out either before putting the hydrant into operation or after repair work. Testing is an important part of any fire protection system because... it allows you to promptly identify equipment malfunctions and eliminate them. Any inspection of fire-fighting equipment always begins with an external inspection to identify external problems. If visual inspection the hydrant does not reveal any malfunctions, then a column is placed on it, after which the water is started and pumped out of the riser. As a rule, any work on the plumbing network requires a permit, but fire officials do not need one.

Hydrant operation

It is very important to follow all the rules when using a hydrant, because... if it breaks down, there may be no access to water, which is fraught with serious consequences. Before starting work with a hydrant, a warning sign is installed, which should be well lit in dark time days. If work is carried out at sub-zero temperatures, then after completion, the remaining water in the riser must be drained into the drain hole to prevent freezing and icing of the hydrant. Before working with a hydrant winter time years, it is necessary to notify the water service employees about this. To gain access to the fire hydrant, you must open the well hatch. This can be done using a crowbar or special hook. IMPORTANT to know that various gases can accumulate in wells; for this reason, smoking is strictly prohibited in wells. Before installing a dispenser on the hydrant, all valves must be closed. When the column is installed, it is necessary to open the hydrant valve, which will be accompanied by the noise of filling water. All work on the hydrant must be carried out only by specialists.

Each employee undergoes fire safety certification. Description

The column is installed as follows:

• screw it onto the hydrant so that the square rod of the hydrant fits into the hole in the square coupling of the column;
• screw the KPA column onto the hydrant, rotating the body clockwise;
• then open the hydrant valve and rotate the socket wrench counterclockwise, now water will flow into the column cavity;
• We attach the hoses to the nozzles of the column, opening the valves, water from the column will flow into the hose line.

The KPA fire column consists of a housing (lower and upper), a key, a valve and connecting heads. Both halves of the housing are bolted to each other and sealed with a rubber O-ring. At the bottom of the body there is a thread that is intended for screwing the column onto a fire hydrant. At the top of the column there are 2 valves with 80 mm UP to shut off and regulate the flow of water passing through the outlet pipes, on which connecting heads are installed for connecting fire hoses to them.
A test must be performed to verify the column. A pressure of 1.5 MPa is applied to the column for 2 minutes, while moisture is allowed to escape at three points, but not more than 20 drops every minute.
It is necessary to store the column with the locking devices closed, but leaving space for a gap between the valve gaskets and the mounting sockets, which ensures their elasticity.

Working pressure – 1.0 MPa (10 kgf/cm2);

Conditional passages:

inlet pipe – 125 mm;

outlet pipes – 80 mm;

The opening and closing force of locking devices at operating pressure is 450 N (45 kgf);

The torque on the handle of the socket wrench when it rotates (without pressure) is 20 N.m (2 kgf.m);

Dimensions:

length (according to the fangs of the connecting heads) – 430 mm

width (along the speaker body) – 190 mm

height – 1090 mm

Weight – 16 kg.

To draw water from the water supply network, a fire stand is installed on the fire hydrant. Pressure-suction fire hoses are connected to it and the pump of the fire truck (through the water collector) (one pressure hose is allowed, and the other is pressure-suction). Then, by smoothly rotating the fire pump socket wrench handle counterclockwise, open the hydrant valve. By rotating the handwheels of the fire column head counterclockwise, the valves of the pressure pipes of the column are opened. After this, water from the water supply network flows through the hydrant, standpipe and fire hoses to the pump of the fire truck. Close the hydrant valve in the reverse order with the valves of the dispenser pressure pipes closed. When removing (unscrewing) the fire column, its socket wrench must be stationary. The remaining water in the hydrant riser must drain through the drain hole. If the drain hole is clogged or closed, after finishing work in winter period, water from the fire hydrant riser can be removed (pumped out) using a foam mixer of a fire pump (working as when taking foam concentrate from an external container).

In the absence or low productivity of a water supply system, a non-piped water supply is used for fire extinguishing.

Non-pipe water supply is carried out from natural (rivers, lakes, seas, etc.) and artificial (ponds, reservoirs) water sources. Natural water sources, compared to artificial ones, have the advantage of an almost inexhaustible supply of water. However, there are also disadvantages - it is not always possible to freely and quickly withdraw water from them due to high, steep or swampy banks. To ensure reliable water intake, natural and artificial water sources are equipped with fire entrances or piers (see Fig. 5.33) capable of withstanding the load of fire trucks.

The entrance area (pier) is located no higher than 5 m from the horizon level low waters(GNV) and above the horizon high waters(GVV) by at least 0.7 m. Piles and load-bearing beams of the site are made of wood, reinforced concrete and metal. The width of the platform flooring must be at least 4 - 4.5 m, with a slope towards the shore and have a strong side fence 0.7 - 0.8 m high. At a distance of 1.5 m from the longitudinal edge of the platform, a thrust beam with a section of not less than 25x25 cm. If the water depth is less than 1 m (taking into account freezing in winter), a pit (pit) is built at the point where it is collected. In winter, to ensure quick water intake, non-freezing ice holes are installed near entrances and piers (at water intake points). To do this, they freeze it in ice. wooden barrel so that most of its height is below the lower surface of the ice (see Fig. 5.34).

The barrel is filled with insulating material, closed with an upper bottom and a lid, and covered with snow. The location of the fire hole is indicated by a sign. Before drawing water, it is necessary to remove the lid and the upper bottom of the barrel, remove the insulation from it and knock out the lower bottom.

If it is impossible to access the water source (swampy banks, etc.), gravity (receiving) wells are installed (see Fig. 5.35), connected to the water source by gravity pipelines.

Gravity wells have dimensions of at least 0.8×0.8 m in plan. They are made of concrete or stone and equipped with two covers, the space between which is filled with insulating material in winter to protect water from freezing. The well is connected to the water source by a gravity pipe with a diameter of at least 200 mm. The end of the pipe on the side of the water source is located at least 0.5 m above the bottom and at least 1 m below the low water horizon. The intake end of the pipe is protected with a metal mesh that prevents the entry of foreign objects. The depth of water in the well must be at least 1.5 m. The gravity well is provided with free access, designed for the simultaneous installation of two fire trucks.

If it is not possible to use natural water sources for fire extinguishing, construction of fire reservoirs is provided: digging ponds or reservoir reservoirs (see Fig. 5.36).

Reservoir reservoirs are more permanent structures than trench reservoirs and are more reliable in operation. Reservoir reservoirs can be of different types

forms. Their depth ranges from two to five meters. Each tank has a 0.6x0.6 m hatch with a double lid and a ventilation pipe. The hatch is used for water intake by fire fighting equipment and for inspection of the tank. A pit with a depth of at least 0.4 m is provided under the hatch. The bottom of the tank must have a slope towards the pit. The capacity of fire reservoirs is based on extinguishing fires within three hours.

If direct collection of water from a fire reservoir is difficult, receiving wells are installed, which in design resemble the gravity wells discussed earlier. In this case, in front of the receiving well, on the connecting pipeline (its minimum diameter is also 200 mm), a well with a valve is installed, the steering wheel of which is located under the manhole cover.

Water must be drawn from each fire reservoir by at least two fire pumps. Driveways with turning areas for fire trucks measuring at least 12×12 m are arranged to reservoirs and receiving wells. Illuminated (fluorescent) indicator signs are installed at the location of fire reservoirs and gravity wells, on which symbols indicate the type of water source, and with digital values ​​the water supply in m3 and the number of fire trucks that can be installed at the same time.
