Tip 1: Safety rules in the gas sector

Certain safety rules in the gasthe economy must be known and observed without fail. Owners of private estates, as well as persons who are responsible for the production process carried out in a gas economy, must submit to them.

From clear compliance with certain rulessafety in the conduct of the gas economy directly depends on the health and life of people, the safety of their property. Similar requirements are specified in special regulatory documents. This is a direct responsibility for the long-term use of equipment, for maintaining all engineering communications in working order.

Basic requirements for gas operation

Modern safety rulesin a certain way, provide for certain duties regarding the use of gas in everyday life. Here you can note such things as: 1. The instructions for the safe use of gas in organizations that are responsible for the operation of such facilities, as well as strict compliance with the basic instructions for the use of gas equipment. If necessary, it is required to call an employee of a gas production enterprise. This is necessary to make some changes in the taps of such engineering communications, in the process of their operation, if some faults are detected in the equipment used. At the same time, the admission of specialists should be provided at any time. To ensure its own security, it is necessary to verify the availability of a business card. It is important to observe the most economical use of gas, as well as to make timely payments. There is a requirement for the competent and careful use of devices, to make timely maintenance. It is required to periodically organize a verification of the head during the winter, carefully clean it from frost and frost. 5. It is necessary to ensure the quality of ventilation in the structure, in particular the installation of chimneys. If a breakdown is found during a thorough inspection, it is required to immediately repair gas equipment. There are also some requirements for construction companies. Settlement in gasified apartments and houses is allowed only if all the necessary documentation is available, which will confirm the passage of a certain briefing on the safety of the apartment owner, as well as on the compliance of the facility with all security requirements.

Summing up

Only with full observance of safety rulesin the gasified economy, it is possible to ensure a clear operation of all the structures that are responsible for the operational process. More importantly, one can guarantee the preservation of human health and life. Strict observance of such rules will prevent the emergence of tragic situations.

Tip 2: How to install AGB

Gas fired boilers AGV Used for heating buildings and residentialpremises equipped with systems with water circulation. Installation of boiler equipment is carried out by specialists of the operating organization of gas facilities. Minor errors in the installation or start-up of the system can lead to fire and death.

Instructions

Make sure that the chimney in the room complies with the safety rules for gas consumption and gas distribution systems. If necessary, clean the chimney.

Select installation location AGV. The device can be mounted onany surface in a room equipped with a ventilation system. It should be remembered that when installing the device, it is necessary to ensure free air access to its rear wall and bottom.

Install the gas cock, by means of which the gas supply to the device will be regulated. The crane is installed on the gas supply pipe in front of the unit.

Connect the unit to the heating system using threaded connections.

Install the dirt filter on the return line located in front of the unit.

Fit the expansion tank at the top of the main riser.

Fill the system with a prepared coolant. Check the presence of draft in the chimney.

Set the thermostat knob to the "closed" position. To do this, turn it clockwise until it stops. Open the tap located on the gas pipeline.

Slide the flap and open the inspection window. Wrap the air regulators as far as they will go.

Take the paper and fold out of it a long strip. Light the paper strip, press the "start" button and, holding it, hold the paper to the ignition. Keep the button pressed for 15-45 seconds. Release the button and make sure that the flame does not go out.

Light the main burner. To do this, turn the thermostat counter-clockwise. Adjust the air supply by turning the flow control knob. Set the desired temperature mode.

Tip 3: Why hatches are round

The first sewer hatches appeared morea hundred and fifty years ago. In those days, communal services in big cities began to develop actively. Sewage systems were created from connected wells. To close the exit sites of the wells to the surface, hatches with lids were used. They had at first different outlines, but gradually the round shape replaced other types of manholes. Why did this happen?

Instructions

In the range of cast iron foundriesSewer hatches occupy far from last place. At the end of the XIX century, such enterprises were quite a lot, while each of them produced hatches for their city or even the district. There were no uniform standards, there was a wide variety of shapes and sizes of foundry products. On the covers of manholes that were manufactured in those days, you can trace the geography and specificity of the city economy.

With the advent of cars in the streets of citieshatches began to make new demands, because heavy trucks could exert pressure on the covers of sewerage wells of several tons. Hatches began to be designed in accordance with the class of roads, their purpose and the intensity of traffic flows. Steel began to be developed standards relating to the dimensions of hatches, their shape and the permissible weight of the covers.

Gradually, the sewer hatch found its usualtoday round shape. Those covers, which were installed on the roadway, began to supply the tail, which protruded into the well, acting as a kind of stabilizer. Such a device prevented the hatch cover from sliding to the side when the wheels of the car hit it.

Why, for most hatches, a roundthe form? There are several reasons for this. Firstly, products of this form are very simple to manufacture, it requires less material than any other similar size. Secondly, a cast-iron cover of round form is easier to transport or even simply roll from place to place.

Another reason is the safety ofoperation of wells. The fact is that the round hatch cover can not fall into the well under any circumstances, which is explained by the peculiarities of this geometric shape. But the square lid can easily pass through the well's throat, if you place its rib diagonally across the square, which can be dangerous for the life and health of workers during repair and maintenance work inside the engineering structure.

However, today there are also manhole coverssquare or even irregular shape. As a rule, they correspond in shape to wells, which are designed to close. Choosing a form for the hatch, manufacturers often are guided by the designation of wells. Such engineering facilities are used not only for sewerage, but also for the creation of water supply systems, heat and gas networks.

Tip 4: How to protect housing from gas leakage

Our accommodation should be safe, and we can take care of this ourselves, if we comply with some simple rules

Many in the house have gas: a stove in the kitchen, a column in the bathroom or a gas boiler for heating. All these devices require special handling and compliance with safety rules. 1. Beauty does not require sacrifice. Do not block the gas equipment (pipes, faucets and chimneys) with decorative walls or a kitchen set. In this case, access to gas engineering is difficult, so it will be difficult to identify the cause of the gas leakage and block it. Do not also build a chimney if you have a gas column, because the combustion temperature in the chimney can reach 600 degrees, and then the fire is imminent. So do not cover the box with a suspended ceiling.2. Ventilation is a guarantee of safety. As you know, household gas has no smell, so ethylmercaptan is added to it - its smell is felt even at the lowest concentrations. However, a person can not feel if the gas content is from 5 to 15%, and this can cause choking or fire. Therefore, ventilation should work fine. Extractor - also a good way out, because The gas is lighter than air and, when leaking, quickly rises to the ceiling. If there is a gas column in the bathroom, here it is necessary to check the ventilation constantly and not to put the door too tight, there are cases of suffocation from gas poisoning in the bathroom. The door must open to the outside so that a person can quickly open it. 3. The gas cooker does not replace the heater. Do not heat the apartment with a gas stove. constantly open fire is dangerous: in the air at this time, harmful to humans carbon monoxide, sulfur compounds and other by-products. If there are drafts in the house, the fire may go out and gas will flow into the apartment. Do not use the gas stove as a dryer for laundry - it can catch fire. Do not trust professionals. Do not install gas appliances unless you have special knowledge. Modern gas economy is a complicated thing, and you can not twist the screws in the old fashion. A small inaccuracy - and gas will enter the apartment a little, but constantly. Check the service life of the product - it must be at least 15 years old. Now, quite often cheap materials for podvodki have a service life of 2 or 3 years, later they shrink and crack. And the owners do not even know about it, because they did not check the certificate and did not look carefully at the documents. To avoid this, invite a gas specialist who will check and correct everything if necessary. In case of any malfunction of the gas equipment, you can call your gas service or call 04.
