Its gas is acquired during preparation by the addition of special odorous liquids - ethanethiol and ethyl mercaptan. But what if the smell of gas?

Signs of a gas leak

In order for gas pipelines to be safe, it is necessary to identify and eliminate the leak of blue fuel in a timely manner. This is especially true for intra-house wiring, although communications laid underground are close located to the industrial or residential area, they also pose a considerable danger when they depressurization

Gas leaks contribute to the corrosion of gas pipes, weld seams when opportunities are not enough temperature compensators, poor-quality welding, insufficient reliability of the thread, flanges and the gas itself technicians.

How to prevent gas leakage

This should begin to be thought out even at the design and modification stage of the living space. The planning of the future gas pipe system and the placement of gas equipment must be entrusted to people with this right.

When installing gas equipment should be guided by the relevant rules. Moreover, the craftsmen with the necessary tolerances are required to deal with this matter. So, for example, a gas stove is installed no further than 400 cm from a metal pipe. There must be a dielectric insert between the gas tap and the hose.

To connect the gas equipment, it is necessary to install a Euro outlet with a grounding conductor near. When installing a combination gas stove with an electric oven, you need a separate three-core cable with a cross section of 4.5 mm or more2laid openly. In the input panel, it should move away from a separate 16 amp circuit breaker.

The gas stove is connected to the pipe using a special gas hose, properly certified. Moreover, it should be purchased in company specialized stores.

Gas hose

Today, gas stoves often come with protection that prevents the leakage of gas fuel by an automatic cut-off mechanism (gas control). He reacts to the disappearance of the flame, say, from a sharp gust of wind (draft). In such cases, the protective device shuts off the gas. Its principle of operation is simple: when the flame breaks down, the temperature sensor, cooling down, gives an impulse to the tap that blocks the supply of blue fuel.

Also, to prevent leakage, you can install a sensor (signaling device) that responds to gas pollution. They are installed in the kitchen and in the gas boiler room. Some models can automatically turn off the fuel supply if there is an explosive gas-air atmosphere in a confined space.

In kitchens, gas duplication alarms are usually installed household duplicating (SZBD). There are other types of these devices: SIKZ, SAOG, SZPS, etc.

The gas analyzer is connected to a separate 220 volt outlet. The location of the sensor is a wall on which it is mounted vertically at a distance of more than 100 cm from the edge of the gas-thermal unit and 15 ± 5 cm, departing from the overlap, when controlling methane or at the same elevation from the floor, if subject to control liquefied gas.

There are professional gas analyzers, with which you can not only establish where the gas is leaking, but also determine the composition of the gas-air mixture. Such a device costs 30,000 rubles.

Rules for the operation of gas equipment

Operating rules can be found in current regulatory documents, such as the Decree of the Gosstroy of Russia of 09/27/2003. No. 170, Decisions of the Cabinet of Ministers of the country dated July 21, 2008 No. 549 and dated May 14, 2013 No. 410.

According to these and other documents, the owners are responsible for the serviceability of gas equipment. Replacement of devices, which are part of domestic gas equipment, is carried out by specialized organizations, when this is specified in the relevant agreement. It is impossible to change these devices yourself, bypassing a specialized institution.

From one scheduled service to another, the owners are responsible for the safe operation of gas equipment. At the same time, they must not violate the rules for the consumption of blue fuel in a house or apartment.

Gas equipment inspection

The frequency of inspection of gas equipment is at least once every 36 months. When the gas technology works out its time, inspection and maintenance are carried out annually.

Gas appliances located in the housing are inspected for a fee. When concluding a collective agreement, the work of the serviced institution is paid in a separate line in receipts with utility bills. Having completed the inspection of gas equipment, the specialist draws up the relevant act.

Payment is determined by the amount of gas technology that is in the house or apartment. The average price for inspection, adjustment and repair of plates is 500 rubles for owners. If, in addition to the stove, there are other gas positions in the form of meters, gas columns, etc. payment will increase to 1 thousand rub.

Important safety precautions

  • It is necessary to strictly adhere to the relevant instructions and at the same time economically consume gas fuel.
  • Remind the head of the housing office about the need to check the ventilation and chimneys every three months.
  • The cleanliness and serviceability of gas equipment should always be maintained. If a large capacity is placed on the burner, then the ribs of the stand should be high.
  • Regularly inspect the ventilation system.
  • Prohibit children and persons who are not familiar with the rules of working with gas equipment from handling them.
  • Do not use garages, storage rooms and balconies for storing gas cylinders.
  • Refill gas cylinders only at designated points.
  • Do not engage in the independent connection and disconnection of home gas stoves.
  • In no case should you heat the living quarters with the help of gas stoves.
  • Do not violate the sequence of ignition of gas equipment: first, a match is ignited and only then the gas supply opens.
  • Before leaving the house, turn off the gas appliances and shut off the supply of gas fuel stored in the cylinder using a valve.
